Built differently
Military-Grade Privacy Architecture
CyclePrivate is engineered differently. While others harvest data, we built a fortress around it.
- 01
100% Offline-First
No cloud sync by default. Your data is stored locally on your device using encrypted storage.

Biometric App Lock
Integrated with Face ID / Touch ID so only you can open the app, with auto-lock timeout.

Granular Permissions
Centralized checks for required permissions — the app only accesses exactly what it needs.
