Data Storage & Security
🏠 Local Storage (Device-Only)
Most of your data is stored locally on your device using Flutter's Shared Preferences. This means:
- ✅ Your notes, passwords, and QR history remain on your device
- ✅ We do not have access to your master password or decrypted data
- ✅ Your data is not uploaded to any cloud server by default
- ✅ You maintain full control over your information
🔐 Security Measures
- Master Password Protection: Your password vault is encrypted and protected by a master password that only you know
- Local Encryption: Stored passwords are encrypted before being saved to disk
- No Network Transmission: Your sensitive data never leaves your device
- Secure Development: We follow Flutter and Android security best practices
⚠️ Your Responsibility
- Keep your master password secure and confidential
- Use a strong, unique master password
- Do not share your device with unauthorized users
- Enable device-level security (screen lock, biometrics) on your phone

🚫 No Analytics SDKs
We do not use Google Analytics, Firebase Analytics, or any third-party analytics SDKs that track user behavior across apps.
