Calculator Lock - Photo Vault

Is your phone truly private?
What happens when you hand your unlocked phone to a friend or family member?
With Calculator Lock - Photo Vault & App Hider, you never have to worry again. Behind a fully working calculator interface lies a secret, encrypted space where your private apps, photos, videos, and files remain completely invisible to everyone but you.

Why choose Calculator Lock?
Unlike standard app lockers that merely put a password on your apps, we offer absolute invisibility. If they can't see it, they can't snoop on it!
