App Lock

Intruder selfie
Takes a photo of anyone who enters a wrong PIN, with a break-in log.
Fake PIN
Forced to open it? The fake PIN opens a separate, nearly empty vault.
Passwords & notes
Encrypted with your master password. Password generator and a health check for weak or reused passwords.
Full encrypted backup
One file with everything, saved to Google Drive or your phone. Restore it on a new phone.
Recycle Bin + recovery
Deleted items go to the bin; even after "delete forever" they can be recovered for 30 days.

Kryvo has no internet permission — it physically cannot send your data anywhere.
Encryption
AES-256-GCM. Passwords are protected by your master password (PBKDF2-HMAC-SHA256, 310,000 rounds). Media keys live in the Android Keystore.
Zero data collected
No account, no analytics, no ads. The Play Store data-safety label reads "No data collected".
Your keys, your data
Forgot the password and no recovery key? Nobody can open the vault — not even us. Set up a recovery key in Settings.
