It looks like a calculator. It hides everything private.
Calculator Vault keeps your photos, videos and notes behind a secret code. To anyone else, it's just an ordinary calculator sitting on your home screen.
Free to download. Contains ads and in-app purchases starting from INR 100 to INR 5,000.
Everything stays private, nothing looks suspicious.
Under the calculator is a full file manager built for privacy — import existing media, capture new media directly, and organize it your way.
Screen-down auto actions
Someone walks in? Flip your phone face-down and the vault reacts on its own — closes itself, jumps to another app, or loads a decoy website.
Hide photos & videos
Import from your gallery, or share files in directly from any app's share sheet — they vanish from your public Photos app instantly.
Shoot straight into the vault
Capture new photos and record video with the built-in camera — nothing touches your public gallery.
Private notes
Keep passwords, journal entries or anything text-based in a built-in encrypted notes editor.
Fingerprint unlock
Use the fingerprint sensor already on your phone to get into the vault — and the calculator lock screen — in one touch.
Built-in viewers
Pinch-to-zoom photo and GIF viewing with slideshow and shuffle, plus a full video player.
Themes & dark mode
Recolor the whole vault, or switch to a dark theme built to go easy on your eyes at night.
Same app your friends see. Very different app you use.

Questions people actually ask.
I forgot my password. How do I get back in?
Open the calculator, type 11223344, then press =. That opens the password-reset screen with your secret question — answer it correctly to set a new password. If you added a recovery email, you can also reset using an emailed code.
If I uninstall the app, are my hidden files still there?
No. Unlock the vault and move your files back out before you uninstall — once the app is removed, anything left inside it is gone for good, even if you reinstall.
Is Calculator Vault free?
Yes, it's free to download and use. It contains ads and offers an optional one-time in-app purchase to remove them.
What Android version do I need?
Calculator Vault runs on Android 4.4 and up, and works on both phones and tablets.
