これは何？

MetaRadar, also called Bluetooth Radar, is an Android app for monitoring the Bluetooth Low Energy (BLE) devices around you. BLE devices such as headphones, fitness trackers and AirTags broadcast packets that can contain persistent identifiers, which may make a person traceable. The app analyzes these broadcasts to show which nearby devices appear to use privacy protections such as randomized addresses and which may be trackable.

You can create custom filters for the radar and set alerts based on device identifiers, types or behaviors, including when a device keeps moving with you over time. It also reads data from available GATT services through a service explorer, identifies device types from metadata, and estimates the approximate distance to each device. All processing runs offline, and the app does not share personal data or location.

The project is intended for education, security research and personal investigation. Users are responsible for complying with applicable laws.
