About this app

Protect your device! Safeguard your data! Anytime, anywhere!

DeviceSentinel turns your smartphone into a smart anti-theft system — alerting you instantly when someone moves, unplugs, or tampers with your device.

No accounts. No cloud. No battery drain. Just pure, offline protection.

Key Features include:
• Motion Alarm — Triggers a loud alarm if your phone is picked up or moved
• Charger Alarm — Notifies you instantly if the power cable is unplugged
• Proximity Guard — Set a safe distance; alerts if your phone moves too far
• Offline & Private — Works 100% offline. No login or internet required
• Battery Efficient — Designed to run silently in the background
• Quick Arm/Disarm — One-tap control with customizable sensitivity
• Custom Alerts — Choose vibration, and sensitivity settings

Why DeviceSentinel?

Most anti-theft apps require cloud access, or drain your battery. DeviceSentinel gives you real protection without the hassle:
• No account needed
• No internet dependency
• Minimal permissions
• Local-only data — your privacy is respected

Built for travelers, students, freelancers, and anyone who needs peace of mind in shared or public spaces.

Perfect For Situations Like:
• Leaving your phone on a table at a café or library
• Charging your device in airports or co-working spaces
• Securing your device while you sleep

Tips for Best Use
• Adjust motion sensitivity based on the surface (e.g. table vs sofa)
• Use Proximity Guard in stationary environments
• Allow required permissions for full background functionality
