AppLock Pro – Lock Apps & PIN
NexFlow Ltd
AppLock Pro is the premium app locker built for people who take their privacy seriously. Lock any app on your Android phone — WhatsApp, Instagram, Facebook, Gmail, banking apps, and more instantly using fingerprint or PIN. Your phone. Your rules.
Tired of wondering who's been through your phone? You shouldn't have to. App Lock Pro puts a silent, instant lock on every app that matters — no ads interrupting you, no data leaving your device, no ongoing cost. Just clean, powerful app locking that works every single time.
🛡️ WHO IS THIS FOR?
Anyone who shares a phone with a partner, family member, or coworker. Parents who want to keep children out of banking or private apps. Anyone who's felt that uncomfortable moment of handing their phone to someone and immediately regretting it. If that's you, this privacy lock gives you back full control — quietly and permanently.
🔐 FINGERPRINT & BIOMETRIC LOCK
Unlock your protected apps in under a second using your device's built-in fingerprint sensor. The fingerprint app lock integrates directly with your Android biometrics — no third-party access, no cloud upload. Instant, seamless, and completely private. For devices without a fingerprint scanner, PIN and password lock work as a reliable primary method.
📱 LOCK ANY APP — WHATSAPP, INSTAGRAM, BANKING & MORE
App Lock Pro works as a universal app locker across your entire device. App Lock can lock WhatsApp, Instagram, Snapchat, Telegram, Facebook, Gmail, Google Photos, your gallery, banking apps, settings, and any system app with a single toggle. One tap to lock. One fingerprint to open.
🔢 PIN & PASSWORD LOCK
Set a strong custom PIN or passcode as your primary lock or as a backup to biometrics. The PIN lock screen appears instantly when a protected app is opened — before any content is visible.
🛑 UNINSTALL PROTECTION
This is the feature that separates App Lock Pro from every other app locker on the market. Using Android Device Administrator privileges, App Lock Pro prevents anyone from deleting or force-stopping the app without entering your PIN first. They cannot remove the lock. They cannot bypass your privacy protection by uninstalling. You remain in full control — always.
🌐 OFFLINE — ZERO DATA COLLECTED
App Lock Pro operates entirely offline. No internet permission is requested or used. Your PIN, your locked app list, and your usage data never leave your device. No cloud sync. No account required. No analytics. No data collection of any kind.
⚡ LIGHTWEIGHT & BATTERY EFFICIENT
Built to run silently in the background without draining your battery or slowing your phone. App Lock Pro uses minimal system resources while maintaining real-time app locking across all your protected apps. No performance impact on your device.
✅ SETUP GUIDE — READY IN 60 SECONDS
1. Install App Lock Pro and open it.
2. Set your PIN or enable fingerprint lock.
3. Grant Usage Access permission — required to detect when a locked app is opened.
4. Enable Display Over Apps — required to show the lock screen overlay.
5. Select the apps you want to protect with a single toggle.
6. Optional: Enable Uninstall Protection for maximum security.
Done. Every app you selected is now locked.
🔒 PERMISSIONS — HONEST DISCLOSURE
• PACKAGE_USAGE_STATS — detects when a locked app is launched so the lock screen appears instantly.
• Device Administrator — used exclusively for Uninstall Protection. Prevents the app from being removed without your PIN. You can disable this permission at any time in your device settings under Security → Device Admin Apps.
• No internet permission. No camera access. No microphone. No location. No contacts. No accounts. Nothing else.
App Lock Pro is the right choice for anyone tired of ad-filled, subscription-heavy, data-collecting free applock apps. One purchase. Real privacy. Yours forever.
