Auto-lock your phone when you fall asleep. Offline, private, no data collected.
Ever fallen asleep watching YouTube or Movies, or scrolling Short Videos - only to wake up with a dead battery and your screen still on? zzzGuard locks your phone automatically when you stop interacting with it. No more wasted battery. No more pocket dials. No more accidental messages sent at 3 AM. ━━━━━━━━━━━━━━━━━━━━ ### How It Works zzzGuard monitors your screen for inactivity. When you haven't touched your phone for a set period, a gentle "Still watching?" prompt appears. If you don't respond, your phone locks itself — just like a sleep timer, but smarter. ━━━━━━━━━━━━━━━━━━━━ ### Key Features 🔒 **Auto Screen Lock on Inactivity** Set a custom timeout (5–60 minutes). If you stop interacting with the screen, zzzGuard steps in and locks your device automatically after prompt. 📱 **Per-App or Global Monitoring** Choose specific apps to monitor—like Netflix, YouTube, Instagram, Disney+, or Prime Video or enable Global Mode to track inactivity across all apps at once. ⏰ **Custom Schedule / Sleep Timer** Set active hours so zzzGuard only runs during your sleep time for example, 11 PM to 6 AM. Outside those hours, it stays out of your way. 👁️ **"Still Watching?" Smart Prompt** Before locking, a countdown prompt dialog gives you a chance to tap "I'm here." Miss it, and the screen locks. Simple. 🔋 **Save Battery Overnight** No more waking up to 10% battery because your screen stayed on all night. zzzGuard keeps your battery healthy. 🛡️ **100% Offline & Private** No internet permission. No analytics. No tracking. No ads. No server calls. No data collection — ever. Everything runs entirely on your device. ━━━━━━━━━━━━━━━━━━━━ ### Perfect For • Falling asleep while watching videos or movies in bed • Kids using your phone, auto-lock when they stop watching • Preventing pocket dials and accidental screen taps • Saving battery by auto-locking idle screens • Anyone who wants a smarter screen timeout ━━━━━━━━━━━━━━━━━━━━ ### Why zzzGuard? Your phone's built-in screen timeout is limited to a few minutes and applies everywhere. zzzGuard is different: ✓ Works per-app — only monitors the apps you choose ✓ Custom timeout — from 5 to 60 minutes ✓ Scheduled activation — runs only when you need it ✓ Smart prompt dialog — gives you a chance before locking ✓ Zero data — completely offline, completely private ✓ Lightweight — minimal battery usage, no background drain ━━━━━━━━━━━━━━━━━━━━ ### Accessibility Service & Privacy promise zzzGuard requires Accessibility Service permission solely to detect inactivity and lock your screen. This data is processed on-device and is never stored, logged, or transmitted anywhere. We have no servers. We collect nothing. ━━━━━━━━━━━━━━━━━━━━ **Your Phone Sleeps When You Do.** Download zzzGuard and never worry about falling asleep with your screen on again.
