Hide and lock your private photos and videos inside a secret calculator safe.
Calculator Lock hides your private photos and videos behind a calculator that really works. Switch between standard and scientific modes while your hidden pictures stay out of your gallery, opened only by your secret PIN. Security Features PIN Protection - Type your 4-digit PIN on the calculator keypad and press '=' to open your private vault. To anyone else it is just a calculator, with no sign of the photo lock behind it Decoy Vault - Set a second, decoy PIN that opens a separate vault. Keep harmless photos there and your truly private files in your real secret vault Private Albums - Give any album its own password, so even an open vault keeps your most personal photos locked Privacy Screen - The vault stays blank in recent apps, blocks screenshots and locks itself the moment you leave the app Flip to Hide - Turn your phone face-down to close the vault instantly and open the calculator, your home screen or an app you choose Calculator Modes - Use standard mode for everyday sums or scientific mode for trigonometry, logarithms, powers, roots and factorials, with five calculator themes Media Management Hide Photos & Videos - Import pictures and videos in all common formats from your gallery. After import, remove the originals from your public gallery in one tap, so they stay only in your private photo vault Album Organization - Create as many albums as you like, each with its own emoji and cover. Sort them your way and switch between grid and list view in your hidden gallery HD Media Player - View photos and play videos in full quality without leaving the vault. Move, share or export files back to your gallery whenever you want Private Camera - Take photos and record videos inside the app. They go straight into your vault and never appear in your phone's public gallery Private Browser - Browse the web from inside the vault. History, cookies and site data are cleared when you leave the browser or the vault locks Private Notes - Write notes inside your hidden vault, away from your regular apps Trash Recovery - Deleted photos and videos go to Trash first and stay there until you empty it, so you can restore them to any album Backup & Recovery Backup Protection - If enabled, you can protect your vault contents against device loss, theft, or damage. If something happens to your phone, your memories and important files remain safe and recoverable with our secure backup recovery system. Keep your hidden photos and private videos protected across devices FAQ Forgot your PIN? Set a recovery pattern in Settings. Then, on the calculator, press C, press and hold '=' and draw your pattern to set a new PIN. Without a recovery pattern, a PIN can't be recovered. File Safety: Your files are stored inside the app. Without backup, uninstalling the app permanently deletes them. With backup on, reinstall the app and sign in to restore them. Supported Formats: Photos and videos in all common formats, including JPG, PNG, GIF, MP4 and MOV. Decoy Mode: Your decoy PIN opens a completely separate vault, so you can show the calculator vault without revealing your real secret photo album and video safe. Need more help?
