Best Encrypted Note-Taking Apps in 2026: A Founder's Honest, In-Depth Guide

Quick answer. The best encrypted note-taking apps in 2026 are Standard Notes and Notesnook for pure encrypted notes, Joplin for open-source Markdown with opt-in end-to-end encryption, Obsidian for a huge plugin ecosystem (with encrypted sync but not encrypted files at rest), Anytype for a graph-based encrypted knowledge base, Proton Docs for encrypted cloud documents, Cryptee for encrypted web documents and photos, and Filarr if you want your notes and your actual files in one workspace, encrypted per file on your own disk with cloud sync as an option rather than the point. There is no single winner. The right pick depends on whether you mostly write notes, whether you also need to store files, and how much you care about your data living locally versus in someone else's cloud.

Why "encrypted" quietly became the feature that decides everything

Most people do not wake up wanting encryption. They want to find that contract from eighteen months ago, keep their journal private from a housemate, hold onto the messy notes that make up a half-finished book, and stop losing the one PDF that mattered. Encryption only enters the picture the day you realize that the app holding all of that can also read all of that, and that "can read" quietly means "could leak," "could be subpoenaed," "could be trained on," and "could change its terms next quarter." The tools we trust with our thinking have slowly become the tools that know the most about us, and in 2026 that is no longer an abstract worry. It is the reason a normal person who has never said the words "threat model" out loud starts typing "encrypted notes app" into a search bar.

I built Filarr because I lived exactly that arc. I wanted one place for my files, my notes, and the links between them, and I wanted it to be private by default rather than private if I remembered to turn something on. When I went looking for that in the existing market, I found a strange gap. There were beautiful note apps that stored my words in plaintext on a server. There were encrypted note apps that could not hold my files. There were file vaults that could not take a note. And there were local-first tools that treated encryption as an afterthought or a paid add-on. So I want to be honest with you up front: this guide is written by someone with a horse in the race. That is exactly why I am going to spend most of it telling you where the other apps genuinely beat mine, because a roundup where the author's product wins every row is worthless, and you can smell it a mile off.

The goal here is not to crown one app. It is to give you the mental model to judge any encrypted note app you encounter, this year or next, and then to place the eight tools that matter in 2026 onto that model honestly. By the end you should be able to answer three questions for yourself: what am I actually protecting, who am I protecting it from, and what am I willing to give up in convenience to get that protection. Those three answers, not a feature checklist, are what decide the right app for you.

What "encrypted" actually means, before anyone sells you on it

Here is the uncomfortable truth about the phrase "end-to-end encrypted," which you will see stamped on nearly every app in this guide: it is doing a lot of work, and it does not all mean the same thing. The useful way to cut through the marketing is to stop thinking about ciphers for a moment and start thinking about scenarios, because encryption is only ever meaningful relative to a specific attacker. If you cannot name who you are defending against, you cannot judge whether an app defends you. So let me lay out the four scenarios that matter for notes, and then, later in the guide, walk each app through them.

The first scenario is the honest-but-hackable server. The company running your notes app is not evil, but its database gets breached, or an employee goes rogue, or a government hands it a warrant. The question that matters is simple: when someone with full access to the server looks at your data, do they see your notes or do they see noise? For a plaintext app like classic Notion, they see your notes. For a genuinely end-to-end encrypted app, they see ciphertext they cannot open, because the key never left your device. This is the single most important property, and it is the one the phrase "zero-knowledge" is trying to name. If you want the precise version of this distinction, I wrote a whole piece on end-to-end versus zero-knowledge encryption that untangles the two terms people use interchangeably and wrongly.

The second scenario is the stolen or seized device. Your laptop is taken, your phone is lost, a border agent asks you to hand it over. Server-side encryption does nothing for you here, because the threat is local. What protects you is encryption at rest on the device itself, ideally so that even someone holding the physical disk sees only encrypted files until the correct password unlocks them. This is where a lot of "encrypted" note apps quietly fall down, because they encrypt data in transit and on the server but leave a decrypted working copy sitting in a local database that anyone with your unlocked machine, or your disk image, can read.

The third scenario is the weak password. Encryption is only as strong as the secret that unlocks it, and humans pick terrible secrets. The defense here is not the cipher, it is the key derivation function, the deliberately slow math that turns your mediocre password into a key while making brute-force guessing painfully expensive for an attacker. An app using hundreds of thousands of iterations of a modern derivation function buys you time even with a bad password. An app that skips this, or uses a weak setting, hands an attacker your notes the moment they get the encrypted blob. This is invisible in the marketing and decisive in reality.

The fourth scenario is losing access yourself. This one cuts the other way. The stronger the encryption, the more real the risk that you lock yourself out permanently. In a plaintext cloud app, a forgotten password is a minor annoyance: click reset, the company mails you a link, you are back in. In a true zero-knowledge app, the company cannot reset your password, because it never had your key. That is the whole point, and it is also a loaded gun pointed at your own foot. So recovery design, the recovery phrase, the backup key, the account-death plan, is not a footnote. It is a core feature, and I will judge every app on it. Notice that none of these four scenarios required me to name a cipher. That is deliberate. The cipher matters, but it is the last thing to worry about, not the first, because in 2026 essentially every serious app uses a strong one. What separates them is everything around the cipher.

The apps, one honest profile at a time

Standard Notes: the disciplined purist

Standard Notes is the app that treats encryption as a religion rather than a feature, and I mean that as a compliment. Every note is encrypted by default with XChaCha20-Poly1305, one of the strongest authenticated encryption schemes in wide use, and the company has built its entire reputation on the idea that it cannot read your notes even if it wanted to. It is open source, it has been independently audited, and it has been around long enough to have proven the model rather than just promised it. If your need is narrow and sharp, encrypt my writing, sync it everywhere, let me trust it for a decade, Standard Notes is close to the platonic ideal. The free tier gives you unlimited encrypted notes across your devices, which is genuinely generous.

Where it costs you is breadth and price. The free plan is deliberately spartan: plain text, no fancy editors, no file attachments to speak of. The good stuff, rich editors, Markdown, file attachments, note history, lives behind the Productivity plan at roughly 90 dollars a year, with a Professional tier around 120 dollars a year for larger file storage. That is not unreasonable for what it is, but it is a real subscription for what remains, at heart, a note app. Standard Notes is not trying to be your file manager, your project hub, or your knowledge graph. It is trying to be the most trustworthy text box in the world, and it largely succeeds. If you want to see how its design philosophy compares directly with mine, I did a full head-to-head in Standard Notes versus Filarr.

Notesnook: the friendly zero-knowledge challenger

Notesnook is what happens when someone looks at Standard Notes, agrees with the security stance, and decides the experience should be warmer and the platforms broader. It encrypts everything end to end with XChaCha20-Poly1305 for content and Argon2 for key derivation, which is a modern and well-chosen combination, and it is fully open source with the crypto documented in the open. Critically, it ships real apps on Windows, macOS, Linux, iOS, Android, and the web, so if you are the kind of person who does half your thinking on a phone, Notesnook meets you there in a way many privacy tools do not. It leans into rich notes, notebooks, tags, and a genuinely pleasant editing experience, so it feels less like a security appliance and more like a note app that happens to be locked down.

The honest caveats are about the free tier and the paid ladder. The free plan is tight, with a small monthly sync allowance and small file limits, which pushes serious users toward paying. The paid tiers are reasonably priced, an Essential plan around 20 dollars a year, a Pro plan around 50 dollars a year, and a Believer tier around 90 dollars a year, but the model is still fundamentally cloud-sync-as-product: the app pushes your encrypted data through Notesnook's servers, and heavy use means a subscription. It is a superb choice, arguably the best pure encrypted note app for most people in 2026, and I say that as a competitor. If you want zero-knowledge notes on every platform with a gentle learning curve, start here. I compared it with my own approach in Notesnook versus Filarr.

Joplin: the open-source workhorse

Joplin is the grizzled, dependable open-source option, the one that has been quietly syncing Markdown for years and does not much care about being pretty. Its notes are plain Markdown, which is a genuine virtue: your data is never trapped, because Markdown is the closest thing the note world has to a universal, future-proof format. Its encryption uses AES-256 with a key derived from your master password, it encrypts both note bodies and attachments, and the key never leaves your device. It syncs against almost anything, your own Nextcloud, Dropbox, S3, WebDAV, or the managed Joplin Cloud, and it is free and self-hostable, with Joplin Cloud plans starting around 3 dollars a month if you would rather not run infrastructure.

Here is the sharp edge you must not miss: end-to-end encryption in Joplin is opt-in, not on by default in the traditional setup. You have to go into settings and enable it. This is the single most common way Joplin users think they are protected and are not, because they synced to Dropbox for months before turning encryption on, leaving plaintext copies in a cloud they do not control. Joplin Cloud has improved this by wiring encryption into the sync flow, but the mental model still requires you to care and act. Joplin also asks for patience: the interface is functional rather than delightful, and setting up sync and encryption is a small project rather than a one-tap affair. For the person who values open source, data portability, and self-hosting above polish, it is excellent. I wrote up the full comparison in Joplin versus Filarr.

Obsidian: the plugin universe (with an encryption asterisk)

Obsidian is the app most of the internet's power users actually love, and I am not going to pretend otherwise. It is local-first in the sense that matters day to day: your notes are plain Markdown files in a folder on your disk, yours forever, editable by any tool, and its graph view and backlinks make it a joy for building a personal knowledge base. Its plugin ecosystem is in a category of one. There is a community plugin for almost anything you can imagine, and that extensibility is a genuine, hard-to-replicate moat that no other app in this guide comes close to matching. If your bottleneck is capability and customization, Obsidian wins, full stop.

But here is the asterisk that this entire guide exists to flag: Obsidian does not natively encrypt your notes at rest. Those Markdown files sit on your disk in plaintext. Anyone with access to your unlocked machine, your backups, or your synced folder can read every word. Obsidian's paid Sync service, around 4 dollars a month billed annually, is end-to-end encrypted with AES-256, so your notes are protected in transit and on Obsidian's servers, but that protects the sync, not the files on your laptop. To get encryption at rest you are stitching together full-disk encryption or a community plugin, and community encryption plugins are a fragile place to put your secrets: they are maintained by volunteers, they can break on updates, and a bug in one is a bug in your privacy. Obsidian is also closed source, which is worth knowing given how much you entrust to it. It is a phenomenal thinking tool with an encryption story you have to build yourself. My side-by-side is in Obsidian versus Filarr.

Anytype: the encrypted graph

Anytype is the most ambitious of the bunch, an attempt to build an end-to-end encrypted, local-first, graph-based knowledge base that could plausibly replace Notion for people who refuse to store their second brain in plaintext. Everything is encrypted so that neither Anytype nor its infrastructure can read your pages, it stores data locally and syncs over an encrypted peer-to-peer network rather than a classic central server, and it gives you objects, relations, and types, a genuine data model rather than just a pile of documents. The free tier is generous, with local-first encrypted storage and a gigabyte of sync included, and paid plans like Builder run around 99 dollars a year for much larger storage.

The honest caveats are maturity and licensing nuance. Anytype's client is source-available under its own Any Source Available License rather than a standard open-source license, with only the core sync libraries under MIT, so "open source" is a fuzzier claim than it is for Standard Notes or Notesnook. The data model, while powerful, has a learning curve, and the peer-to-peer sync, while clever, can be less predictable than boring old client-server sync when your devices are rarely online at the same time. If you want an encrypted Notion-shaped workspace with a graph and you enjoy learning a system, Anytype is compelling. I went deep on the trade-offs in Anytype versus Filarr.

Proton Docs and Proton Drive: encrypted cloud, made in Switzerland

Proton is the trust brand of the privacy world, and Proton Docs, built on top of Proton Drive, brings that reputation to documents and notes. Everything is end-to-end encrypted by default, it is backed by a company with a long track record in encrypted email, and it offers real-time collaborative editing of documents and spreadsheets on a private platform, which almost no other tool in this guide can match. There is a 5 gigabyte free tier, Drive Plus runs around 4 dollars a month billed annually, and the full Docs experience comes with Proton's Unlimited bundle. If your instinct is "I trust Proton and I want encrypted documents I can share and collaborate on," this is a strong, safe answer.

The philosophical caveat is that Proton is cloud-first, not local-first. Your documents live in Proton's cloud by design. It is encrypted cloud storage, which is a genuinely good thing and a real upgrade over Google Docs, but it is not the same as data that lives on your own disk and treats the cloud as optional. If Proton has an outage, if you are offline, or if you ever leave, your relationship to your own documents is mediated by Proton in a way it is not with a local-first tool. This is a difference in kind, not degree, and I spelled it out fully in Proton Drive versus Filarr. Proton is the best answer for encrypted collaborative cloud documents. It is not trying to be a local-first workspace, and you should not ask it to be.

Cryptee: the encrypted web notebook

Cryptee is the quiet European option, an Estonia-based, client-side-encrypted service for documents, photos, and notes that runs in your browser. It encrypts on the client so that Cryptee cannot read your documents or see your photos, it is open source enough to inspect, and it is refreshingly honest about being a small, bootstrapped, subscription-funded business with no investors pulling it toward surveillance. Its editor handles Markdown and LaTeX and can even open PDFs and Word documents, and pricing is gentle, a small free tier around 100 megabytes and paid plans starting around 3 dollars a month for 10 gigabytes. For a private encrypted notebook plus photo vault that you reach from any browser, Cryptee is a lovely, under-appreciated pick.

The caveats are scope and heft. Cryptee is web-first, so it does not give you the deep desktop integration, the local file management, or the offline-native feel that a downloaded app provides, and its free tier is genuinely tiny. It is best thought of as a private, encrypted place for documents and photos rather than a full workspace for your projects and files. If that is what you want, it delivers with unusual integrity.

Filarr: notes and files together, encrypted on your disk

Now the part where I tell you what I built and why it exists, and I will try to earn your trust by being precise rather than promotional. Filarr is a local-first encrypted workspace that holds your notes, your actual files, and a graph that links the two, and its defining choice is that encryption is the default state of your data rather than a mode you enable. Every file is encrypted individually with AES-256-GCM, the same authenticated encryption used by Signal, 1Password, and TLS, and if you want the plain-language version of what that name means, I wrote what AES-256-GCM is and why it matters. Crucially, each file gets its own key. That per-file key is wrapped by a key derived from your password, a two-layer design that means compromising one file does not compromise the rest, and I explained why that layout matters in KEK and FEK explained.

The key derivation uses PBKDF2 at 600,000 iterations, following OWASP's 2024 guidance, with Argon2id available as an option, which is the boring, correct answer to the weak-password scenario. Recovery runs through a 24-word BIP-39 phrase, the same standard the crypto-wallet world uses to let you restore access after a disaster. The whole thing runs offline as an Electron and React desktop app on Windows, macOS, and Linux, it handles over 51 file formats, and the cloud sync is genuinely optional: when you turn it on, files upload already encrypted, and the server (Cloudflare R2 by default, or your own S3-compatible bucket if you bring your own storage) stores only opaque blobs it cannot read. It is free forever for local use, with cloud sync starting at 4 euros a month, and the desktop client is open source under the Business Source License 1.1.

So where does Filarr honestly lose? It is younger than most apps here, born in 2026, with a smaller community and a shorter track record. It has nothing like Obsidian's plugin ecosystem. Mobile is still in progress, so if your life runs on your phone, Notesnook or Standard Notes serve you better today. And it is not trying to be your real-time collaborative document editor the way Proton Docs is. Filarr's bet is narrow and specific: if you want your notes and your files in one place, encrypted per file on your own disk, with the cloud as a convenience rather than a dependency, nothing else on this list does exactly that. If that is not your need, one of the other seven is a better fit, and I would rather you find the right tool than the tool with my name on it.

The encryption, walked through the four scenarios

Now let me do what the profiles could not, and run these apps through the four threat scenarios from earlier, because this is where the real differences live and where marketing copy goes to die. Take the honest-but-hackable server first. Standard Notes, Notesnook, Anytype, Proton, Cryptee, and Filarr all pass this cleanly: the server sees ciphertext, and a breach or a subpoena yields noise rather than notes. Joplin passes only if you enabled encryption, which is the recurring asterisk on an otherwise excellent tool. Obsidian's Sync passes for the synced copy, because that channel is end-to-end encrypted, but the files on your disk are a separate matter entirely. And any plaintext cloud app, the Notions and Google Docs of the world, fails this scenario by design, which is the whole reason you are reading a guide about encrypted alternatives. If you want the deeper mechanics of what "the server cannot read it" really requires, zero-knowledge encryption explained lays it out with diagrams.

Now the stolen or seized device, which is where the picture gets more interesting and where a lot of "encrypted" apps quietly stumble. The question is what an attacker sees when they hold your powered-off, locked laptop or a raw image of its disk. Filarr's answer is that they see individually encrypted files, because encryption at rest on your own disk is the entire premise, not a sync side effect. Standard Notes and Notesnook keep local caches encrypted as well, consistent with their security-first design. Obsidian, by contrast, stores plaintext Markdown on disk, so a seized device gives up your notes unless you separately run full-disk encryption, and full-disk encryption only helps when the machine is fully powered down, not when it is asleep and unlocked. Joplin's local database is only protected if you have taken care with disk-level encryption, since its E2EE is oriented at sync. Proton and Cryptee, being cloud-first and web-first, keep less permanent plaintext lying around locally, but they also mean your data's home is the cloud rather than your disk. The lesson is blunt: encryption in transit and on the server is common, encryption genuinely at rest on your own device is rarer, and it is the property that saves you when the threat is physical.

The weak-password scenario is the invisible one, and it is decided by key derivation, not by the cipher name that gets top billing. This is why Notesnook's use of Argon2 and Filarr's 600,000 PBKDF2 iterations matter more than they look: they make each password guess expensive, so that even a mediocre password buys you meaningful time if an attacker ever gets the encrypted blob. An app that encrypts with a beautiful cipher but derives the key with a weak, low-iteration function is a strong door on a paper wall. The frustrating part for you as a user is that this is almost never in the marketing, which is exactly why an app that documents its derivation openly, as the open-source options here do, deserves extra trust. When you cannot inspect the derivation, you are trusting a promise; when you can, you are trusting math.

The fourth scenario, legal or coercive demand, ties the others together. A properly zero-knowledge app can be handed a warrant and truthfully respond that it cannot produce your plaintext, because it never held your key. Standard Notes, Notesnook, Proton, Anytype, Cryptee, and Filarr are all built so that the honest answer to a subpoena is "we have ciphertext and nothing else." That is a profound difference from a plaintext app, where the honest answer is a full export of everything you ever wrote. But notice the trade this creates, and it leads directly into the next section: the very property that makes an app unable to betray you also makes it unable to rescue you. If the company cannot decrypt your notes for a government, it cannot decrypt them for you either when you forget your password. Encryption does not give you safety for free. It gives you safety in exchange for responsibility, and any app that hides that trade from you is lying to you.

How sync actually works, and what happens when it breaks

Sync is where the philosophical differences between these apps stop being abstract and start affecting your Tuesday. The cloud-first tools, Proton foremost among them, treat the server as the source of truth: your document lives in Proton's cloud, your devices are windows onto it, and this is what makes real-time collaboration possible, because everyone is editing the same authoritative copy. The cost is dependency. When the server has an outage, your access degrades, and when you are offline, you are working against a cached copy that has to reconcile later. This is a perfectly reasonable design, and for collaborative documents it is arguably the right one, but it means the cloud is not optional, it is the foundation.

The local-first tools invert this. In Filarr, Obsidian, Joplin, and Anytype, the source of truth is the copy on your disk, and sync is a mechanism for propagating changes between your own devices rather than the place your data lives. The practical consequence is that these apps work fully offline, indefinitely, because being offline is just the normal state with sync paused, not a degraded mode. Filarr's sync, when you choose to enable it, uploads files that are already encrypted on your device, so the server, Cloudflare R2 or your own S3-compatible bucket, only ever holds opaque encrypted blobs. If Filarr the company vanished tomorrow, your encrypted files would still be on your disk, fully usable, because the desktop app does not need the server to function. That is the entire point of local-first, and it is a resilience property you cannot retrofit onto a cloud-first design. I walked through exactly how that stays zero-knowledge at the code level in how Filarr's optional cloud sync works.

Anytype's peer-to-peer sync is a fascinating middle path: there is no classic central server holding your data, and your devices exchange encrypted updates over an encrypted network. This is elegant and genuinely private, but it introduces its own quirk, which is that peer-to-peer sync is happiest when your devices are online together, and can feel less predictable than boring client-server sync when, say, your desktop is off for a week and your phone is doing all the work. Joplin's sync is the most flexible of all, because you point it at whatever backend you like, but flexibility is a euphemism for setup effort, and the failure modes depend on the backend you chose. Obsidian gives you the polished first-party Sync for a fee, or you can rig up your own sync over any file-syncing service, with the crucial caveat that only the paid Obsidian Sync is end-to-end encrypted, and rolling your own over a generic sync service means plaintext notes traveling through and resting in that service. The single most important question to ask any of these apps is not "does it sync" but "what happens when the sync is unavailable, and where do my keys and my plaintext live in the meantime." That question separates a tool you own from a tool that rents you access to your own words.

Recovery: the scenario nobody markets and everybody eventually hits

I want to spend real time here, because recovery is where encrypted apps either respect you or quietly set a trap. In a plaintext cloud app, forgetting your password is trivial: the company holds your data, resets your credential, and you are back in minutes. In a true zero-knowledge app, that convenience is structurally impossible, because the company cannot decrypt what it cannot read. This is not a bug, it is the security property working as designed, but it means the burden of recovery shifts from the company to you, and a well-designed app makes that burden survivable while a badly designed one leaves you one forgotten password away from losing years of work.

The gold-standard pattern, and the one Filarr uses, is a recovery phrase: a 24-word BIP-39 sequence generated when you set up your vault, which encodes the material needed to regain access independently of your password. If you write those words down and keep them somewhere safe, ideally offline, on paper, in a fireproof box, not in the same encrypted vault they are meant to recover, then a forgotten password is a recoverable event rather than a catastrophe. This is the same battle-tested mechanism the cryptocurrency world uses to let people restore wallets after losing devices, and it works because it moves the ultimate secret out of any company's control and into yours. The trade is that the responsibility is now genuinely yours: lose the phrase and the password both, and no one on earth, including me, can get your data back. That is the honest deal, and I would rather state it plainly than pretend encryption is free of consequences.

Standard Notes and Notesnook handle this well within their models, giving you recovery codes or keys and being explicit that account recovery is your responsibility because they cannot see your data. Proton has built a mature recovery system precisely because it learned these lessons in the encrypted email world, offering recovery phrases and secondary methods, though the more recovery paths an app offers, the more carefully you have to think about whether each path is also a potential attack surface. Joplin's story is more manual and tied to your master password and your backend, which suits its self-hosting audience but demands more of you. Obsidian, since your notes are plain files, has the gentlest recovery of all for the notes themselves (they are just Markdown on your disk and in your backups), which is a real convenience, but that is the same property that makes them unencrypted at rest, so the ease is the flip side of the exposure. And the account-death question, what happens to your notes when you die or simply abandon the app, is answered best by exactly the local-first, file-on-disk model: if the plaintext or the recovery phrase lives with you rather than only in a company's servers, your heirs or your future self have a path that does not depend on a company still existing. The uncomfortable meta-lesson is that recovery and security pull against each other, and every app on this list is really just choosing a point on that spectrum. Your job is to pick the point that matches how organized and how careful you actually are, not how organized you wish you were.

The comparison table, with the analysis that keeps it honest

Before the table, a warning about tables: they flatten nuance into checkmarks, and a checkmark hides whether a feature is on by default, opt-in, native, or bolted on with a plugin. Read the rows below with the profiles above in mind, because "yes" and "yes" are often two different animals.

App	Encrypted at rest by default	Cipher / KDF	Files, not just notes	Local-first	Open source	Mobile apps	Starting paid price
Filarr	Yes, per file	AES-256-GCM / PBKDF2 600k, Argon2id optional	Yes, 51+ formats	Yes	Yes (BSL 1.1, desktop)	In progress	4 euros/mo (sync optional)
Standard Notes	Yes	XChaCha20-Poly1305	Limited (paid attachments)	Sync-based	Yes	Yes	~90 USD/yr
Notesnook	Yes	XChaCha20-Poly1305 / Argon2	Attachments	Sync-based	Yes	Yes	~20 USD/yr
Joplin	Opt-in	AES-256 / PBKDF2	Attachments	Yes	Yes	Yes	~3 USD/mo (Cloud)
Obsidian	No (Sync is E2EE)	AES-256 (Sync only)	Attachments in vault	Yes	No	Yes	~4 USD/mo (Sync)
Anytype	Yes	E2EE, P2P sync	Files as objects	Yes	Source-available	Yes	~99 USD/yr
Proton Docs	Yes	E2EE	Yes (Drive)	No (cloud-first)	Partly	Yes	~4 USD/mo (Drive)
Cryptee	Yes	Client-side E2EE	Documents, photos	No (web-first)	Yes	Web/PWA	~3 USD/mo

Read down the "encrypted at rest by default" column, because that is the one this whole guide turns on, and notice how much variation hides behind the shared label "encrypted." Joplin's "opt-in" is not a knock on its cryptography, which is fine, but a warning that the protection is off until you turn it on, and most breaches of trust happen in that gap. Obsidian's "No" with an E2EE-Sync footnote is the most important cell in the table for a lot of readers, because Obsidian is so beloved that people assume it protects the files on their disk, and it does not. Read across the "local-first" row and you see the philosophical fault line: Proton and Cryptee are cloud-first and web-first by design, which is a legitimate choice that buys collaboration and browser access at the cost of your data living on someone else's computer. And read the price column with a grain of salt, because a low sticker price on a sync-metered plan can cost more than a higher price on a plan with room to grow, which is exactly why the next section runs actual scenarios instead of quoting headline numbers.

Where the competitors genuinely win

Let me be concrete and generous, because this is the part that earns the rest of the guide. Obsidian wins on capability and ecosystem, and it is not close. If you want a tool that bends to your exact workflow through community plugins, that renders complex knowledge graphs, that has a decade of tutorials and templates and a passionate community, Obsidian is the answer and nothing here dislodges it. The plugin ecosystem alone is a moat I cannot pretend to match, and if your primary need is a maximally extensible thinking environment and you are willing to handle encryption at the disk or plugin level yourself, you should probably use Obsidian and stop reading comparison articles.

Notesnook wins on being the best all-around pure encrypted note app for most people, especially on mobile. Its combination of zero-knowledge encryption, a genuinely pleasant editor, and real first-class apps on every platform including iOS and Android makes it the tool I recommend to friends who say "I just want private notes on my phone and laptop and I do not want to think about it." Filarr's mobile story is still in progress, and Notesnook's is mature today, so for the phone-centric person Notesnook is simply the better pick right now, and I will not pretend otherwise. Standard Notes wins on longevity and monastic focus: it has proven the encrypted-notes model over many years, it has been audited, and its refusal to be anything other than the most trustworthy text box is a feature, not a limitation, for people who want exactly that.

Proton wins on collaboration and brand trust. If you need to co-edit encrypted documents in real time with other people, Proton Docs does something no local-first tool in this guide does well, because real-time collaboration genuinely wants a shared authoritative copy in the cloud, and Proton pairs that with a reputation for privacy that it has earned over years in the encrypted email trenches. Anytype wins on being an encrypted, graph-native Notion alternative with a real data model, which is a specific and hard thing to build, and Joplin wins on open-source purity, data portability, and self-hosting, giving you Markdown you will be able to read in twenty years and the ability to run the whole thing on your own server with no company in the loop at all. Cryptee wins on being a small, honest, European encrypted notebook and photo vault that you can reach from any browser. Every one of these is a better choice than Filarr for the person whose priorities match its strengths, and if I have described your priorities in this section, take that as a real recommendation, not false modesty.

Where Filarr genuinely wins

Now the other side, stated as plainly. Filarr wins when your problem is not "I need encrypted notes" but "I need my notes and my actual files in one encrypted place." Almost every app in this guide is a note app that grudgingly accepts attachments. Filarr is a workspace where a PDF, a spreadsheet, a photo, and the note that references them all live together, all encrypted, all linked in a graph, across 51-plus file formats. If your real life is a mess of documents scattered across a note app, a cloud drive, and a downloads folder, and you want one private home for all of it, that is the specific gap Filarr was built to fill, and I have written about that daily reality in how to organize your whole digital life in one private workspace.

Filarr wins on encryption being the floor rather than a feature. There is no toggle to forget, no plaintext window before you enabled protection, no plugin that might break. Every file is encrypted per file with its own key from the moment it exists, which means the weak point in most "encrypted" workflows, the gap between installing the app and remembering to turn encryption on, simply does not exist. It wins on the local-first guarantee being real and complete: the app is fully functional offline forever, the cloud is genuinely optional, and when you do enable sync the server holds only opaque encrypted blobs, so there is no version of Filarr's business that requires reading your data. And it wins on price for the person who mostly works on one machine, because it is free forever for local use, with the 4-euro-a-month sync being something you opt into rather than a subscription you need to make the app work at all. If your center of gravity is a desktop, if you have files as well as notes, and if you want encryption you cannot accidentally skip, Filarr is doing something the others are not.

Migration: moving without losing anything

Switching note apps sounds terrifying and is usually more tedious than dangerous, but the friction is real and worth planning for. The single best insurance policy is to favor tools that speak Markdown and export cleanly, because a proprietary format is a cage and Markdown is a passport. Joplin and Obsidian are Markdown-native, so moving between them, or out of them, is close to painless: your notes are already portable text files. Moving out of a more structured app like Standard Notes, Notesnook, Anytype, or Notion means using their export function, and the honest warning is that export quality varies, and the richer the app's data model, the more likely that databases, relations, and embedded views degrade into flatter formats on the way out. Always export and inspect before you delete anything from the source app, and never treat a migration as complete until you have opened the imported result and confirmed your attachments actually came along, because attachments are what silently get left behind.

Coming into an encrypted app specifically, the extra step is that you are not just importing content, you are encrypting it, which for a large library can take a moment and, more importantly, means you now own a recovery phrase you did not have before. Whatever you migrate into, the first thing to do after the import is set up and safely store your recovery method, because the worst possible time to discover you never wrote down your recovery phrase is the day you need it. If you are specifically leaving Notion, which is the most common migration in 2026, I wrote a step-by-step guide for moving a Notion workspace to a private, encrypted app that covers the export-import-verify loop in detail, and it applies in spirit to migrating out of any plaintext cloud tool. The general principle holds across all of these apps: export from the old, import into the new, verify attachments and structure, set up recovery, and only then decommission the original. Do it in that order and migration is an afternoon of tedium rather than a loss.

Price, decoded with real scenarios

Headline prices lie by omission, so let me run three concrete scenarios and show what you would actually pay, because the cheapest sticker is often not the cheapest year. Scenario one, the solo desktop user who works mostly on one laptop, keeps a few gigabytes of notes and files, and rarely needs sync. Here Filarr costs zero, because local use is free forever and this person does not need the cloud. Obsidian also costs zero if this person skips Sync and keeps everything local. Joplin is free and self-hostable. Standard Notes is usable free but cramped, and to get attachments and rich editing you are paying around 90 dollars a year. Notesnook's free tier might just fit, but any real file use nudges you toward its roughly 20-dollar-a-year Essential plan. For the pure local desktop user, the local-first, free-for-local tools win outright, and paying a subscription for an app you use offline on one machine is money spent on a feature you are not using.

Scenario two, the multi-device user who bounces between a laptop, a desktop, and a phone, and genuinely needs sync to keep them aligned. Now the calculus flips, because sync is the paid product for most of these apps. Filarr is 4 euros a month for optional sync, and the local app stays free underneath it, so you are paying only for the convenience. Notesnook lands around 20 to 50 dollars a year depending on how much you store, and it shines here because its mobile apps are mature. Obsidian Sync is about 4 dollars a month, so roughly 48 dollars a year, on top of a free app. Standard Notes Productivity is around 90 dollars a year. Proton Drive Plus is around 4 dollars a month but often makes more sense inside a broader Proton bundle if you also want mail and VPN. For the multi-device person, the meaningful question is not the per-month number but whether the free app underneath still belongs to you if you ever stop paying, and the local-first tools answer that better, because you keep a working offline app when the subscription lapses rather than losing access.

Scenario three, the heavy user with a large library, many gigabytes of files, and a need for lots of sync storage. This is where metered plans bite. Notesnook's higher tiers, its roughly 50-dollar Pro or 90-dollar Believer, and Anytype's roughly 99-dollar Builder, are priced around storage, so a big library pushes you up the ladder. Filarr's bring-your-own-storage option is genuinely differentiating here, because you can point sync at your own S3-compatible bucket and pay commodity storage prices to a provider of your choice rather than a per-gigabyte markup to the app vendor, which for a large library can be dramatically cheaper over years. The broad lesson across all three scenarios is that "free" and "cheap" mean different things depending on whether you are paying for the app, for sync, or for storage, and the tools that separate those three, letting the app be free, sync be optional, and storage be yours, tend to cost the least over the long run for exactly the people who have the most to store.

Open source and licensing: what it actually buys you

People throw "open source" around as a synonym for "trustworthy," and it is worth being precise about what it does and does not give you as a user of an encrypted app. The concrete benefit is inspectability: when the code is public, security researchers and curious users can verify that the encryption is implemented the way the marketing claims, that keys are handled correctly, and that there is no quiet backdoor. For an app whose entire value proposition is "trust us, we cannot read your data," the ability for anyone to check that claim is not a nice-to-have, it is close to the whole point, because a closed-source zero-knowledge claim is a promise you cannot verify. Standard Notes, Notesnook, Joplin, and Cryptee are open source in the full sense, and that transparency is a genuine reason to trust their encryption claims more than an unverifiable promise.

But the licensing landscape in 2026 is more nuanced than open versus closed, and honesty requires naming the shades of grey. Anytype is source-available under its own license rather than a standard open-source one, with only its core sync libraries under a permissive MIT license, so "open source" is a fuzzier claim there than the headline suggests. Filarr's desktop client is open source under the Business Source License 1.1, which lets you read, inspect, and verify the code, the transparency that matters for trusting the encryption, while placing some commercial-use restrictions that a purist would note are not classic open source, and I laid out that reasoning in why Filarr chose BSL 1.1. Obsidian, for all its virtues, is closed source, which is a real consideration given how central it becomes to people's thinking. The practical takeaway is not "only use software with an OSI-approved license," which would rule out tools that are perfectly trustworthy, but rather "for an app that asks you to trust it with encrypted data, prefer one whose encryption you or someone you trust can actually inspect." Inspectability of the crypto is the property that matters most, and it is available across a wider range of licenses than the open-source-purity debate usually admits.

Four people, four right answers

Let me stop generalizing and describe four specific people, because the honest truth is that the best app is a function of who you are, not of which one has the longest feature list. If you are the phone-first note-taker, someone who captures most thoughts on a phone, wants private notes without fiddling, and does not deal in large files, choose Notesnook. Its mobile apps are mature, its encryption is zero-knowledge by default, and its editor is pleasant. You will be protected without having to think about it, and "without having to think about it" is exactly the right standard for someone who wants notes rather than a security project. Filarr, with mobile still in progress, is not your best pick today, and I would rather point you to the tool that serves you now.

If you are the power-user tinkerer, the person who loves customizing tools, builds elaborate knowledge graphs, and enjoys the process of shaping software to your workflow, choose Obsidian, and layer encryption underneath it with full-disk encryption on your machine. You will trade native encryption at rest for an unmatched plugin ecosystem, and for you that is the right trade, because your bottleneck is capability, not privacy tooling, and you are the kind of person who will actually configure disk encryption correctly. If you are the collaborator, someone whose documents are shared and co-edited with others and who wants privacy without giving up real-time teamwork, choose Proton Docs. Local-first tools, mine included, are not built for real-time multiplayer editing, and Proton is, with a trust record to match.

And if you are the digital packrat with a privacy conscience, the person whose life is a sprawl of notes and PDFs and spreadsheets and photos scattered across five apps, who is tired of losing files, and who wants one private, encrypted home for all of it on your own machine, choose Filarr. This is the person I built it for, the one who does not just want encrypted text but wants their whole document life in one encrypted local workspace with a graph tying it together, and who wants encryption to be the default rather than a setting. If that is you, and you have felt the specific frustration of a note app that cannot hold your files and a file app that cannot take a note, that is precisely the gap Filarr exists to close, and I wrote about that exact pain in stop losing files: a calmer way to manage your documents and notes.

Conclusion: pick the trade, not the logo

If there is one thing I want you to take from a guide this long, it is that there is no best encrypted note app, only the best trade for your situation, and every app on this list is really just a different answer to the same three questions: what am I protecting, who am I protecting it from, and what will I give up to get that protection. The apps that win pretend to be effortless are usually hiding the trade rather than avoiding it, and the ones worth trusting are the ones that state the trade plainly and then handle their side of it well. Encryption is not a magic word that makes your data safe. It is a specific bargain: real protection against real attackers, in exchange for real responsibility about passwords and recovery phrases, and any app that lets you believe otherwise is doing you a quiet disservice.

So choose deliberately. If you mostly write and mostly work on a phone, Notesnook. If you want the most extensible thinking tool on earth and will handle encryption yourself, Obsidian. If you want proven, monastic encrypted notes, Standard Notes. If you want open-source Markdown you can self-host, Joplin. If you want an encrypted graph-based Notion alternative, Anytype. If you want encrypted collaborative cloud documents, Proton Docs. If you want a small, honest encrypted web notebook, Cryptee. And if you want your notes and your files together, encrypted per file on your own disk, with the cloud as an option rather than the point, that is the one I built, and I would be glad to have you try it. Whichever you pick, do the boring part first: turn encryption on if it is not on by default, write down your recovery phrase, and store it somewhere your future self will actually find it. The best encrypted note app in the world cannot save data from a lost password. Only you can, and the app's job is just to make that responsibility survivable. For a wider view beyond notes, into files, project management, and team docs, I keep a ranked roundup of the best local-first apps in 2026 that puts these tools in their larger context.

FAQ

What is the most secure note-taking app in 2026? There is no single most secure app, because security depends on your threat model, but the strongest options are the ones that encrypt at rest by default with the server unable to read your data: Standard Notes, Notesnook, Anytype, Proton, Cryptee, and Filarr all meet that bar. Among them, the tools that also encrypt genuinely on your own disk, so a stolen laptop yields only ciphertext, offer the broadest protection. Filarr's per-file AES-256-GCM encryption with a 24-word recovery phrase is designed precisely for the stolen-device and hostile-server scenarios at once.

Is Obsidian encrypted? Not at rest by default. Obsidian stores your notes as plain Markdown files on your disk, so anyone with access to your unlocked machine or your backups can read them. Obsidian's paid Sync service is end-to-end encrypted, which protects your notes in transit and on Obsidian's servers, but to protect the files on your own device you need to add full-disk encryption or a community plugin, and encryption plugins are a fragile place to store your privacy.

Does Notion encrypt my notes? No, not in the end-to-end sense. Notion stores your content on its servers in a form it can read, which is why encrypted alternatives exist in the first place. If server-side readability worries you, the honest move is to migrate to an app where the server sees only ciphertext, and I keep a dedicated guide to encrypted Notion alternatives in 2026 that compares the credible options.

What is the difference between end-to-end encryption and zero-knowledge? They overlap but are not identical. End-to-end encryption means data is encrypted on your device and only decrypted on your device, so it is unreadable in transit. Zero-knowledge is the stronger architectural claim that the service itself never has the ability to read your data, even at rest on its servers, because it never holds your key. In practice the apps you want combine both, and the precise distinction is worth understanding before you trust a marketing badge.

Can I lose access to my encrypted notes forever? Yes, and this is the trade you accept for real encryption. Because a true zero-knowledge app cannot decrypt your data, it cannot reset your password for you, so if you forget your password and lose your recovery phrase, your notes are gone permanently. This is why recovery design matters so much, and why apps like Filarr give you a 24-word BIP-39 recovery phrase that you should write down and store offline, separately from the vault it protects.

Which encrypted note app is best for mobile? Notesnook is the strongest mobile-first choice in 2026, with mature, zero-knowledge apps on iOS and Android and a pleasant editing experience. Standard Notes and Proton also have solid mobile apps. Filarr is a desktop-first workspace with mobile still in progress, so if your life runs primarily on your phone today, a mobile-mature app serves you better right now.

Is open source necessary for an encrypted app to be trustworthy? Open or at least inspectable source is highly desirable, because it lets researchers verify that the encryption is implemented correctly and that there is no backdoor, which matters enormously for an app whose whole promise is that it cannot read your data. That said, licenses vary: Standard Notes, Notesnook, Joplin, and Cryptee are fully open source, Anytype is source-available, and Filarr's desktop client is open under the Business Source License 1.1. The property that matters most is that you or someone you trust can actually inspect the crypto.

How do I move my notes to an encrypted app without losing anything? Export from your current app, import into the new one, and then verify the result before deleting anything, paying special attention to attachments, which are the things that most often get silently left behind. Favor apps that speak Markdown for the smoothest transitions, and once you have imported into an encrypted app, immediately set up and safely store your recovery phrase. My Notion migration guide walks through the export-import-verify loop in detail and applies to leaving most plaintext cloud tools.
