App Lock keeps your private apps safe with PIN, pattern, password, or biometric authentication. Everything stays on your device — no cloud, no tracking.

🔐 LOCK ANY APP
Protect social media, messaging, gallery, banking, and any app on your device. Choose from PIN, pattern, or password lock. App Info access is also protected — no bypassing through Settings.

🔓 BIOMETRIC UNLOCK
Unlock protected apps instantly with your fingerprint or face. Fast, secure, and convenient.

🛡️ UNINSTALL PROTECTION
Prevent App Lock from being removed without your permission. Device Admin protection means no one can quietly uninstall it behind your back.

👻 STEALTH MODE
Hide App Lock from your launcher and recent apps. Access it anytime via a secret dialer code or deep link — only you know it's there.

📸 INTRUDER SELFIE
Catch snoopers in the act. App Lock silently captures a front-camera photo after failed unlock attempts.

⏱️ SMART AUTO-LOCK
Set custom lock delays — immediate, 30 seconds, 1 minute, or 5 minutes. Apps stay unlocked while you're actively using your phone.

🔑 ACCOUNT RECOVERY
Set up a recovery option so you're never permanently locked out, even if you forget your PIN, pattern, or password.

🎨 BEAUTIFUL THEMES
Choose from five handcrafted themes — Aurora, Pearl, Crimson, Obsidian. Light and dark modes included.

🔒 BUILT FOR PRIVACY
• All credentials are hashed with BCrypt — never stored in plain text
• Brute-force protection: 5 failed attempts triggers a lockout
• No internet permission required for core functionality
• No data collection, no analytics on your locked apps
• No cloud backup of your credentials

App Lock is lightweight, fast, and designed to stay out of your way while keeping your social and private apps truly private.
