Daily Apple Privacy Stats and App Tracking Transparency

Daily Apple Privacy Stats and App Tracking Transparency

Over the last few years, Apple has invested heavily in user privacy protections. In December 2020, for instance, with the release of iOS 14.3, the tech giant introduced App Privacy Details to the Apple App Store. This new feature requires publishers to provide information about their app’s privacy features in App Store Connect, including information about the practices of third-party partners whose code they integrate into their products. As such, App Privacy Details enables users to better understand an app’s privacy practices before they download it to their devices.

But Apple didn’t stop there. The April 26, 2021 release of iOS 14.5 was accompanied by more privacy-related changes. Chief among these is the App Tracking Transparency feature, which requires developers to request user permission before tracking them for advertising purposes.

In short, Apple is running a full-court press on behalf of user privacy. So, we here at 42matters decided to leverage our app intelligence solutions to see how publishers have incorporated Apple’s new privacy standards into their strategies.
