We keep saying that we are 'GPS-free' and do not store or share location data with others. Still, the app asks for permission for location data. What's up with that?
Location data technically means much more than just GPS. The phone can determine your location in many different ways, namely via the nearest GSM mast, the Wi-Fi network to which you are connected, a Bluetooth box and your GPS location. Each of these ways involves a different chip in your phone. The GPS chip is only turned on for a very precise location, using the GPS satellites.
We do not turn on this GPS chip. This has two advantages: no invasion of your privacy, but also a much lower battery consumption of your phone, because GPS consumes a relatively large amount of energy.
