About this app
Notes. Encrypted. Local. Nothing more.
Why Cipher?
- Your phone is your vault. Everything stays on device. - No accounts. No login. No tracking who you are. - Small footprint. No bloat. - Auditable. Open source. Every line of code visible. - Privacy by design. No internet permission. Zero telemetry hooks.
What it does NOT do
- Cloud sync - Account creation - Analytics - Advertisements - Internet calls (network config enforces it) - Crash reporting - Any telemetry
Privacy by design
- No INTERNET permission in AndroidManifest - Network security config blocks all outbound traffic at OS level - Passwords never stored — derived on-demand via PBKDF2 - Encryption uses: PBKDF2 (200k iterations) + AES-256-GCM - All data stays on device — Room SQLite database
