Loud anti-theft alarm for snatches, unplugging and failed unlocks
JoltGuard helps protect your phone in public places with instant motion detection, charger unplug alerts, and failed-unlock alarms. FEATURES — FREE ✓ Snatch Alarm When someone grabs your phone, a 100 dB siren sounds, the camera light flashes, and the phone vibrates. Works with the screen off. Trigger sensitivity adjustable in m/s². ✓ Charger Unplug Alarm If someone pulls out the charging cable, the alarm sounds instantly. Perfect for cafés, libraries, airports, and trains. ✓ Failed-Unlock Alarm Wrong PIN or pattern attempts on your lock screen trigger a siren (or silent alert if you prefer). ✓ On-Device Logs Every event is logged with the exact time and GPS location, stored only on your phone. Open them anytime to see what happened and where. ✓ Disarm with Fingerprint or PIN Set your own owner PIN in Settings → Authentication & Terms. Disarm the alarm with your fingerprint/face or PIN (nobody else can). PRO FEATURES — ONE-TIME PURCHASE (no subscription, no ads) ✓ Instant Email Alerts Receive an alert immediately when an alarm fires—includes the time, phone location on a Google Maps link, and more details. ✓ SIM-Change Alert Works with single-SIM and dual-SIM phones. Detects if a new SIM is inserted into ANY slot, even while your own SIM stays in the other slot. Alerts show the slot number and carrier name. No special permission needed. ✓ Low-Battery Last Alert When the battery drops to 15% (not charging), your phone sends one alert with its location, so you know where to find it. ✓ Tamper Alert If someone disables JoltGuard's Device Admin protection, you're alerted immediately with location. PRIVACY & SECURITY - No accounts, no cloud sign-in, no ads, no analytics - Location recorded only when an alarm fires (not continuously tracked) - All data stays on your phone - Pro email alerts go to YOUR email only (no third-party sharing) - Device Admin used only to detect failed unlocks; never locks, wipes, or forces restart PERMISSIONS & HOW THEY'RE USED - Location: Used only to record where alarms happen (requires your permission on launch) - Notifications: Shows the alarm siren and protection status - Device Admin: Detects failed unlock attempts (watch-login only) REQUIREMENTS - Android 11 or later - The app must run in the foreground to keep motion detection active IMPORTANT JoltGuard is a deterrent, not a guaranteed anti-theft system.
