App Lock: Lock Apps & Vault

Keep your apps, photos and chats private. App Lock protects any app with a PIN, pattern or fingerprint, and gives you a private vault for the things nobody else should see.

🔒 LOCK ANY APP IN ONE TAP
• Lock chats, gallery, banking, social and shopping apps
• PIN, pattern or fingerprint unlock
• Quick groups: lock all your social, finance or game apps at once
• Recommended apps: see which sensitive apps are still open

🎨 A LOCK SCREEN THAT FEELS LIKE YOURS
• Three themes: Night, Light and Signal

• Clean, fast lock screen with no clutter

🛡️ PROTECTION CHECK
• The home screen shows what is missing: permissions, the lock service, battery settings and Settings lock

🗂️ PRIVATE VAULT

• Files in the vault are encrypted and only open inside App Lock

🕵️ CATCH SNOOPERS

🏠 SMART UNLOCK
