Who do I have to allow the localization of my device?
The locatization is a condition for Android devices. For these devices, the Bluetooth Low Energy is used to locate the user. To do so, it uses beacons that permanently send the location and Bluetooth for indoor localization.
The Equisense Motion does not use these beacons but instead a Bluetooth connection (Bluetooth 4 or newer) to communicate. For safety reasons, Android devices nevertheless ask for your permission to locate.
This will not happen if you have an iOS device because they separate beacons and simple Bluetooth communication.
Now you are in the know :)
