Calculator Vault: Hide Photos
A real calculator on the outside. A private vault inside.

About Calculator Vault
Calculator Vault looks and works like a real calculator, but entering a secret PIN unlocks a private vault for photos, videos, files, and notes. Everything is protected with AES-256-GCM encryption backed by the Android Keystore, and the app is fully offline — it has no servers, no analytics, no tracking, and nothing ever leaves your device.
What It Does
Disguised as a Calculator
A fully functional calculator hides the vault. Only your secret PIN reveals it.
AES-256-GCM Encryption
Photos, videos, files, and notes are encrypted on-device using the Android Keystore system.
Screenshot Blocking
Vault screens use FLAG_SECURE, so screenshots and screen recording are blocked.
100% Offline
No servers, no backend, no cloud. The app never connects to the internet with your data.
Camera Capture
Take photos straight into the vault — they never touch your public gallery.
Local PIN Recovery
Security questions let you recover access on-device. Nothing is stored anywhere else.
