About this app

Calculator Lock: Photo Vault gives you a private space to hide photos, videos, files and selected apps behind a working calculator.

To anyone opening the app, it looks and works like a normal calculator. Enter your private PIN and tap the equals button to access your hidden photo and video vault.

PROTECT YOUR PRIVATE PHOTOS AND VIDEOS

Import personal photos and videos into your private vault so they no longer appear in your regular gallery. Organize hidden media into folders and access it securely whenever you need it.

• Hide photos from your phone gallery
• Lock and protect private videos
• Organize hidden files in private folders
• View photos with the built-in image viewer
• Play private videos inside the secure vault
• Restore photos and videos when required

SECRET CALCULATOR LOCK

Calculator Lock disguises your private vault as an everyday calculator. The calculator remains fully functional, while your hidden space can only be opened using your secret PIN.

• Working calculator interface
• Secret PIN access
• Fingerprint unlock on supported devices
• PIN and pattern protection
• Discreet access to your private vault

APP LOCK FOR EXTRA PRIVACY

Protect selected apps from unauthorized access. Lock social, messaging, gallery and other personal apps using a PIN, pattern or fingerprint.

Calculator Lock can also notify you when a new app is installed, allowing you to protect it quickly.

INTRUDER SELFIE

Want to know who tried to open your private vault? Enable Intruder Selfie to capture a photo after an incorrect password attempt.

Camera permission is requested only when you choose to enable this feature.

PRIVATE BROWSER

Browse privately without saving your browsing history inside your regular browser. The built-in private browser gives you a discreet place to visit websites and keep your browsing activity separate.

OPTIONAL GOOGLE DRIVE BACKUP

Protect important files before changing your phone, uninstalling the app or resetting your device.

Backup is completely optional. When you enable it, your selected files are backed up directly to your personal Google Drive account. Your backup is not stored on our servers.

You remain in control of your Google Drive backup and can restore your protected files when needed.

PERSONALIZE YOUR PRIVATE SPACE

Customize the appearance of your vault with available themes, wallpapers and dark mode. Choose a style that makes your private space comfortable and easy to use.

For some reason this app can't get "drive level" SD card access, but then it prompts to create a "new folder" which the app won't accept cause it requires "drive level" access and not a "new folder" (?)... as a result, I'm stuck and unable to try the app beyond the SD card access point. I've tried at least 10 different privacy apps and none ever had such problem in this particular device.
