Starting with iOS 14.5, iPadOS 14.5, and tvOS 14.5, you’ll need to receive the user’s permission through the AppTrackingTransparency framework to track them or access their device’s advertising identifier. Tracking refers to the act of linking user or device data collected from your app with user or device data collected from other companies’ apps, websites, or offline properties for targeted advertising or advertising measurement purposes. Tracking also refers to sharing user or device data with data brokers.
