Why is Deezer adjusting the volume while I drive?

I'm not sure if this happened to me too, but from now on I will try to pay attention to it myself.

@PMTours Does this happens connected to Android Auto or Carplay?
Thanks 

I’m experiencing the same thing, and it’s concerning from a privacy perspective. My location services are disabled, I’m not using any connected in-car audio system, and other music apps don’t change their volume based on whether I’m moving or stopped.

What I’d like to understand is: what specific sensor or permission is Deezer using to detect that the phone is moving? If location is turned off, that doesn’t necessarily mean the device has no access to motion sensors, but users should be clearly informed when an app is using that data and for what purpose.

What makes this particularly frustrating is that the volume-normalization setting doesn’t seem to affect this behavior. If Deezer has introduced automatic volume adjustments based on detected movement, there should be a clear setting to disable it completely.

Privacy-conscious users should be able to make an informed choice about whether their device’s motion data is being used. Transparency and a genuine opt-out would be appreciated.
