My mission
Mathis Belouar-Pruvot
Founder and developer of Filarr. Independent developer based in France.
I built Filarr because privacy is a right, not a premium feature.
I believe digital privacy is a fundamental right, not a premium feature. Filarr was born out of frustration with productivity tools that scan, analyze, and monetize their users’ data. My goal: build a complete workspace — notes, files, graph — that genuinely respects the privacy of your data.
Transparency
Filarr’s desktop client is now published on GitHub under Business Source License 1.1 (github.com/matbel91765/filarr). You can read the code that runs on your machine, verify the cryptographic claims, and propose fixes. Cloud sync is live with end-to-end encryption — your files are encrypted on your device before upload. No SOC2 or HIPAA certifications yet. An independent security audit is on the roadmap. I say what exists, what’s in progress, and what’s not there yet.

My Values
Privacy first
Every technical decision is made with privacy as the absolute priority. No ads, no tracking. What the app sends is listed here. And I don’t sell anything.
Honesty
I communicate without exaggeration. The desktop app’s code is public; the server’s is not — that’s a deliberate choice during the initial phase. If a feature isn’t ready, I say so. Trust is built on truth, not marketing.
Data sovereignty
Your data belongs to you. You can export it at any time, in the format of your choice. No vendor lock-in, ever.
