About this app
Your photos, behind a password only you know. LOCK! keeps private photos in an encrypted vault on your phone. Not hidden in a folder — every photo is encrypted with AES-256, and the key comes from your password. Without it the files are unreadable, even to someone holding your unlocked phone. • A password only you know. Your iPhone passcode no longer opens this app. • Face ID for everyday unlocking. • Albums to keep things in order. • Nothing is uploaded. No account, no sign-up, works offline. Please read this before you start: if you forget your password, nobody can bring your photos back — not us, not Apple. There is no reset link and no support that can help. Write it down somewhere safe. Free with ads: 2 albums and 20 photos. A one-time purchase removes the ads and the limits.
