Calculator - photo vault is an Android app for hiding photos, videos, and other files behind a calculator interface. Its vault uses AES encryption and access is controlled with a numeric PIN; fingerprint unlocking is also listed as an option.
Vaults and access
The main vault stores private photos, videos, and other files. A separate Fake Vault can be set up with a different password and used to store alternative photos and videos. The app also lists an Intruder Selfie feature, which captures a photo after an incorrect password attempt.
Fingerprint unlocking provides another listed way to open the vault. Shake Close is intended to close the app when the phone is shaken, giving users a quick way to exit.
Private browsing and appearance
A private browser is included for browsing websites and downloading photos. The description does not specify browser settings or how downloaded files are handled, so those details cannot be confirmed from the available information.
The app also offers colorful themes and a user-friendly interface. The available description does not state a minimum Android version; its minimum OS field contains no version information.
