If you see a request to track your activity, you can tap Allow or Ask App Not to Track. You can still use the full capabilities of the app, regardless of whether you allow the app to track your activity.

The app developer can customize part of the message to explain why the app is asking to track your activity. You can also visit the app’s product page in the App Store for more details about how the app developer uses your data.

If you choose Ask App Not to Track, the app developer can’t access the system advertising identifier (IDFA), which is often used to track. The app is also not permitted to track your activity using other information that identifies you or your device, like your email address.
