Apple’s App Tracking Transparency feature will be enabled by default and arrive in ‘early spring’ on iOS
Apple first announced at WWDC in June that app developers would have to ask users for permission in order to track and share their IDFA identifier for cross-property ad targeting purposes. The plan is to launch these changes in early spring, with a version of the feature coming in the next iOS 14 beta release.
The App Tracking Transparency feature moves from the old method where you had to opt-out of sharing your Identifier for Advertisers (IDFA) to an opt-in model. This means that every app will have to ask you up front whether it is ok for them to share your IDFA with third parties including networks or data brokers.
