Assuming you’re right, it’s really sad that multiple sibling posts assume that the app was doing something shady and selling the user’s data. It shows, in general, how little trust people have in apps on their own phones.
Plenty of app developers have muddied the water enough that apps should have a lower level of trust given to them. Stealing data is a reasonable fear now. It is not reasonable to assert otherwise.
It is therefore reasonable for a person to wonder why geolocation is requested but then be suspicious why it doesn't seem to need it. Regardless of the underlying technical reason. Those technical reasons are part of informed consent. If I don't have informed consent, do I really have consent?
Its also not a sad state at all. Its healthy. Its part of the modern landscape that someone can be suspicious and rightly so. If not, you're setting people up for misfortune. Is there some reason you want people to blindly trust like this? That seems almost abusive to me.
This is almost all apps. Your default assumption should be that anything on the big app stores is being as malicious as they can get away with -- especially if it is a forced install leveraging some product you have already purchased that could easily be sent over a standard protocol.
_Maybe_ the app is fine, but in the cases I've checked big corporations abusing your privacy is the norm.
