Why Does This App Need Bluetooth?
Bluetooth isn't just for headphones. Apps use Bluetooth for proximity tracking, indoor location, and device fingerprinting. According to Facebook's privacy policy, they collect 'information about nearby Wi-Fi access points, beacons, and Bluetooth devices' to improve location accuracy and enable features like finding friends nearby. TikTok's policy similarly lists Bluetooth data under automatically collected device information.

Frequently Asked Questions
Why does an app need Bluetooth permission?
Apps use Bluetooth for several purposes beyond audio: proximity detection (knowing when you're near a specific location), indoor navigation (Bluetooth beacons in shops and airports), device fingerprinting (identifying your device), and social features like finding nearby friends. Facebook's privacy policy explicitly states they collect Bluetooth data for location and social features.
Can apps track my location using Bluetooth?
Yes. Bluetooth beacons placed in physical locations (shops, airports, venues) can detect your phone when you're nearby. Apps with Bluetooth permission can receive these beacon signals and report your indoor location. Meta's privacy policy describes collecting 'Bluetooth signals' as part of their location data collection.
Is Bluetooth permission dangerous?
Bluetooth permission carries privacy risks beyond what most users expect. On Android 12+, the 'Nearby devices' permission (which includes Bluetooth scanning) is separate from location permission, but can still be used to infer location. You should only grant Bluetooth permission to apps that genuinely need it for a specific feature you use.
How do I stop apps using Bluetooth for tracking?
On iOS: Settings > Privacy & Security > Bluetooth — revoke permission from apps that don't need it. On Android 12+: Settings > Apps > [App] > Permissions > Nearby devices — deny for apps that don't need Bluetooth. Turning off Bluetooth entirely when not in use also prevents beacon tracking.
