Why Secure Notes
Privacy is the default, not an upsell.
No analytics on your content. No developer keys. No server-side reset link. The engineering choices we made reduce the number of people who could ever read your notes to exactly one: you.
Zero-knowledge architecture
Keys are derived on-device from your password. They never leave. The publisher cannot decrypt your content.
No content analytics
The app does not scan your notes for advertising, ML training, or anything else. Ever.
Minimal permissions
Face ID and iCloud only. No location, no microphone, no contacts, no notifications.
Audited cryptography
AES-256 (FIPS 197) with keys derived via PBKDF2. Named ciphers, documented choices.
