It's behind you!
to clarify (again)
The HM DCC app MUST ask for locations services to use bluetooth, it's an Android only thing, Apple does not make this stipulation.
When you install the app you can turn off any permissions, but you must leave location services and nearby devices on as a bare minimum. If you want to use the camera then leave that permission on.
The HM DCC app does not track users precise location and also does not track "third Party" so cannot gather information that you may have entered into other apps such as amazon, facebook etc etc
Depending on your device during install it may default to all permissions, or may not, it's device and possibly OS version specific.
