NotesPy — encrypted notes app for people who actually care about their privacy.
KEY FEATURES
• Local-first architecture: all data stays on your device, encrypted with AES-256
• Two-mode security: simple notes unlocked by biometrics, sensitive notes protected by additional password
• Multiple vaults with independent passwords for organizing sensitive content
• Backup to YOUR own Google Drive (Android) or iCloud (iOS) — we don't run any sync server
• Markdown support with live preview
• Image attachments preserved in original quality
• Color labels for note organization
• Light and dark themes
• Biometric app lock (Face ID, Touch ID, fingerprint)
PRIVACY BY DESIGN
• No account required for using the app
• No telemetry, no analytics, no ads, no tracking
• We don't see your notes. Ever. Our servers don't have them.
• Your backup is encrypted with a key derived from your recovery passphrase — only you have it
• Open about our threat model: see our website for full security documentation
ADVANCED SECURITY
• Recovery via 12-word passphrase (BIP-39 compatible) and QR code
• Optional self-destruct triggers: inactivity timeout, failed password attempts
• Optional duress password support for plausible deniability scenarios
• All backups encrypted before leaving your device
WHO IS THIS FOR
NoteAgent is built for journalists, activists, security researchers, lawyers, and anyone who needs more from a notes app than what Google Keep or Apple Notes provide. If you understand what a recovery passphrase is and why it matters, you'll feel at home.
WHO IS THIS NOT FOR
If you want cloud sync between multiple devices in real-time, you want a collaborative tool, or you don't want to deal with managing your own backup keys — this app is not for you. We recommend looking at other notes apps instead.
OPEN SOURCE COMMITMENT
The cryptographic core of NotesPy will be open-sourced for independent audit. See our website for repository links and security audits.
