App Lock is a lightweight and easy-to-use privacy protection tool. Whether it's social media, banking apps, or your photo gallery, you can lock them with a single tap. Keep your phone secure from snoopers and prevent privacy leaks when borrowing your phone to others. App Lock helps you "Lock, Hide, and Manage" your digital life. 🔒 Core Feature: App Lock Lock Any App: Secure your social apps (WhatsApp, Facebook, Instagram), Gallery, SMS, Contacts, and banking apps. Flexible Security: Prevent unauthorized access and guard against accidental touches. Simple Management: Easily lock or unlock apps with a clear list view. Perfect for keeping your personal data safe from prying eyes. 📷 Intruder Selfie Catch Snoopers: If someone tries to unlock your apps with the wrong password/pattern, App Lock will automatically take a photo of them (Camera permission required). Security Log: The photos are saved locally on your device, letting you know who attempted to access your private apps. 🙈 Privacy Protection & Notification Hiding Hide Notifications: Mask sensitive preview content in your notification bar to prevent privacy leaks. Safe Browsing: Protect your sensitive apps from being peeked at in public. 🖼️ Photo Vault (Safe Gallery) Media Protection: Move your private photos and videos into a secure vault. Keep it Private: These files will be locked away, ensuring that no one can view them when casually scrolling through your gallery. 🧹 Junk Cleaner Free Up Space: Intelligently scan and remove useless cache, residual files, and junk files to reclaim your storage space. Lightweight: Keep your device clean without deleting your important personal files. 🔐 Permissions & Privacy We value your privacy. App Lock requires certain permissions (such as Usage Access, Camera, and Storage) solely to provide app locking, intruder detection, and file cleaning features. Local Processing: All sensitive operations are performed locally on your device. Full Control: You can manage or revoke these permissions in your system settings at any time.
