The catch, of course, is that while developers are required to disclose this information to continue releasing and updating apps, all of the information developers provide will be self-reported, which could still leave some possibility for
foul play.
Apple’s Developer site cautions that developers will be required to disclose all the information they and their third-party partners collect and keep their “labels” up to date. For example, if an app needs to know your precise location to work, you’ll know that before you even download it. If GPS functionality is ever removed from the app, a new label will have to reflect that. Apple does offer some exceptions when these label disclosures are optional, but the important thing to know that if an app intends to track you consistently, you’ll know about it before it’s on your phone.
