Kindly note that Actofit does not track your location by asking for location permission.
Android operating system 6.0 and above require GPS (Location) to be turned on for searching and synchronizing Bluetooth devices (operating system 10.0 and above require authorization to locate) to use Bluetooth.
kindly provide the permissions to proceed with the app.

Caution: BLE scanning needs location permissions as BLE scanning identifies objects that could be used for geolocation. Turning off Location services will turn off Bluetooth scanning.
