Privacy
Last updated 26 June 2026
Fleece AI Brain is local-first. Your knowledge graph lives on your own device as plain Markdown files. You can use the product fully without ever sending your content to us.
What we store
If you create an account, we store the minimum needed to operate it: your email address, authentication tokens, and billing metadata handled by our payment processor. We do not sell personal data and we do not run advertising.
Cloud sync & encryption
Cloud sync is opt-in. When enabled, your notes are end-to-end encrypted on your device before they leave it. We store ciphertext only — we cannot read the contents of your graph. Encryption keys never leave your devices.
Telemetry
We collect privacy-preserving, aggregate product analytics (for example, which features are used) to improve the product. This data is not tied to the contents of your notes. You can opt out in settings.
Your rights
You can export your data at any time — it is just Markdown — and you can delete your account and associated cloud data on request. If you are in the EU/EEA, you have rights of access, rectification, erasure, and portability under the GDPR.
