App Lock: Photo Vault & Locker

App Lock lets you lock any app with a PIN or pattern, hide private photos and videos in an encrypted vault, and disguise the app so no one knows it's a security tool. Keep your personal data private — even when someone else is using your phone.

🔒 APP LOCK
• Lock any app with a 4-digit PIN or a custom draw pattern
• Choose how quickly apps re-lock after you leave — immediately, 30 seconds, 1 minute, 5 minutes, 15 minutes, or 30 minutes
• Lock Android Settings to prevent anyone from disabling your security setup
• Get a reminder when a new app is installed so you can lock it right away
• Search and filter your app list to find and protect apps quickly

Whether you share your phone with family, lend it to a friend, or just want to keep personal apps private — App Lock makes sure only you can get in.

🗄️ PRIVATE PHOTO VAULT
• Hide photos and videos so they disappear from your gallery
• Files are stored with AES-256 encryption and protected by your PIN or pattern
• Your encryption key is generated on your device and stored in the Android Keystore — never uploaded anywhere
• Import photos and videos from your gallery into the vault with one tap
• Export files back to your gallery whenever you need them

The photo vault is completely separate from your gallery. Hidden files are invisible to other apps, cloud backups, and anyone browsing your phone.

🎭 APP DISGUISE
• Change App Lock's icon and name to look like a Calculator, Weather app, Notes, Clock, or Files
• The disguise appears on your home screen and app drawer — no one will know it's a security app
• Tap the disguise icon, enter your PIN or pattern, and you're in

App disguise is one of the most effective ways to keep your locker app hidden from curious eyes.

🔑 FORGOT YOUR PIN OR PATTERN?
• Set up 3 personal security questions as a backup recovery method
• Answer 2 out of 3 correctly to reset your PIN or pattern and regain access
• Built-in cooldown after repeated wrong attempts to prevent brute-force

🔧 BUILT FOR EVERYDAY USE
• Two lock methods — PIN or pattern — switch anytime in settings
• Per-app auto-lock timeout: set different re-lock delays for different apps
• New app install reminder: get notified when a new app is installed and lock it immediately
• Multiple languages supported — use App Lock in your preferred language
• Lightweight design with minimal battery and memory usage

App Lock combines an app locker, encrypted photo vault, and app disguise in one place. If you're looking for an app lock with pattern, a PIN lock for apps, or a way to hide photos and videos privately — App Lock covers all of it without needing multiple apps.
