Some reports have indicated that Apple has started enforcing an Apple Store rule about location data more stringently. The 9to5mac reported that the tech giant has already eliminated a number of apps from the App Store that share the location of users to third parties without their knowledge. In the letter forwarded to the affected developers, Apple informed them that their applications didn’t meet with Legal sections 5.1.1 and 5.1.2 of the App Store Review Guidelines. Those sections state that apps must not transmit location data of a user to third parties without authorization from the user and for unapproved purposes. Apple also informed them that they should remove any code, framework or SDK used for location data collection and third-party sharing before their apps can be listed on the Store again.
