About Fox Sentinel
Fox Sentinel is an anti-theft alarm app designed to help protect your phone when it is connected to a charging cable or wired headset.
Arm the app while your charging cable or wired headset is connected. If the cable is unplugged, Fox Sentinel immediately triggers a loud alarm to help deter theft and alert you.
Key features
- Loud anti-theft alarm when a cable is unplugged
- Works with charging cable and supported wired headset connections
- Full-screen alarm experience designed to get your attention fast
- PIN-protected disarm flow
- Simple, focused setup
- Event logging for alarm activity
- Privacy-conscious design with local on-device settings
How it works
1) Connect your USB cable or wired headset
2) Arm protection in the app
3) If the cable is disconnected, the alarm is triggered
Fox Sentinel is built for users who want a simple anti-theft alarm for desks, public spaces, travel, charging stations, and other everyday situations where added deterrence can help.
Daily use cases:
1. Public transportation
Connect a wired headset and secure the cable to your belt, bag, or clothing while riding the train or bus. If someone tries to steal your phone and unplugs the cable, the alarm can sound immediately.
2. Phone charging in public
Plug your phone into a charger at an airport, café, library, or shared workspace. If someone unplugs the charging cable and takes the phone, the alarm can be triggered.
3. Studying or working in a café
Keep your phone charging beside you while you study or work. If the cable is disconnected unexpectedly, Fox Sentinel can alert you right away.
4. Travel and waiting areas
Use it in airports, stations, hotel lobbies, or waiting rooms when your phone is plugged in and not always in your hand. An unexpected unplug can trigger the alarm.
5. At the gym or in shared spaces
If your phone is charging or connected by cable nearby while you move around, the app can help alert you if someone disconnects it and tries to take it.
