iPhone owners with iOS 14.3 installed are starting to get warnings when apps track their activities across other apps and websites. This new privacy feature has been in the works for some time, and some app developers have protested against its implementation. Facebook, for example has complained about the requirement that it must ask permission to track its users and collect the resulting data.
All apps listed in the Apple App Store now have an "App Privacy" section to inform users on how an app utilizes data. This allows iPhone and iPad users the ability to decide if they want to install an app based on the data it tracks. Alls apps must have its privacy policies listed after December 8, 2020.
