Calculator Vault: Hide Photos

A real calculator on the outside. A private vault inside.

01 — Overview

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.

02 — Features

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.

03 — Privacy

What never happens

  • No analytics, crash reporting, usage tracking, or advertising SDKs of any kind

Permissions it asks for
