ChronoAuth is a privacy-focused, offline authenticator application designed to generate time-based one-time passwords (TOTP) securely on your device.
Your privacy is a core principle of this app. This policy explains what data is collected, how it is used, and—most importantly—what is not collected.

Specifically:
- ❌ No personal information

The app functions fully offline and does not require an internet connection.
4. Backup & Restore (Local Only)

- Backups are encrypted using a password you define
- The app has no access to your backup files after export

5. Permissions
The app may request certain permissions strictly to support core functionality:
| Permission | Purpose |
