About this app

Vault is a secret photo vault and calculator lock in one — a private photo vault disguised as a real, working calculator. Open the app and it is a calculator. Type your PIN, press equals, and your secret photo vault opens.

Unlike other calculator vault apps, Vault shows zero ads and collects zero data. Your private photos and private pictures stay encrypted on your phone, in a hidden photo vault only you can open.
