❓ Frequently Asked Questions

SentryRF is a counter-surveillance app that helps you detect potential tracking devices by scanning for WiFi and Bluetooth signals around you. It analyzes device behavior patterns to identify devices that may be following you.

Yes, SentryRF can detect AirTags, Tiles, Samsung SmartTags, and other Bluetooth trackers. However, some trackers use privacy features that may limit detection. SentryRF works alongside (not as a replacement for) manufacturer apps like Apple's "Find My" which have direct access to their own tracker protocols.

Detection accuracy depends on many factors including signal strength, environmental interference, and device type. SentryRF provides confidence indicators and suspicion scores rather than definitive identifications. A high-score device warrants attention, but does not prove malicious intent.

No. All data stays on your device. SentryRF has no servers and does not collect, transmit, or store any of your information. We can't see what devices you detect, where you go, or anything else. Your privacy is protected by design.

Android requires location permission to scan for WiFi and Bluetooth devices—this is an Android security requirement, not our choice. We also use your location to map where devices are detected so you can see patterns over time. Your location is never transmitted anywhere.

The only internet usage is downloading map tiles from OpenStreetMap to display the map view. No personal data, device detection data, or usage information is ever transmitted.

The suspicion score (0-100) indicates how likely a device is to be tracking you based on its behavior. Factors include: how often it appears, at how many locations, signal consistency, and device type. Higher scores mean more suspicious patterns, but are not proof of tracking.

SentryRF detects all nearby WiFi and Bluetooth devices, including your own. You can add your devices to the whitelist by tapping on them and selecting "Add to Whitelist." Whitelisted devices won't trigger alerts.

Yes, SentryRF can scan in the background. Enable background scanning in Settings and grant background location permission when prompted. A notification will show when scanning is active.

Go to Settings → Clear All Data to delete all detected devices and sightings. You can also delete individual devices from the device list. Uninstalling the app removes all data completely.

Check that: 1) Location permission is granted, 2) WiFi and Bluetooth are enabled on your device, 3) Location services are turned on in system settings. Some devices may also have battery optimization that prevents background scanning—try disabling it for SentryRF.

The map requires an internet connection to download tiles from OpenStreetMap. Check your internet connection. If you're offline, the map may show a blank area, but your device data is still being collected.
