ATT and LAT raw data for devices running iOS 14

At a glance: Use ATT to understand user privacy preferences in iOS14. Staring in iOS 14 Limit ad tracking (LAT) is deprecated. 

ATT values

  • Starting iOS 14: Apple ATTrackingManager (ATT) provides the status values for app tracking authorization.
  • AppsFlyer gets ATT from the following sources:
    • AppsFlyer SDK V6.X or later embedded in the app.
    • By API from advertisers. For example, S2S API. 
  • ATT is available in raw data reports.
  • Advertisers use ATT to gain a better understanding of user privacy preferences.
  • In some cases, ATT is populated by values defined by AppsFlyer. They are indicated by the prefix af in the table.

af_authorized

IDFA use permitted for one of the following reasons: 

  • Device iOS version: prior to iOS 14.
  • The event reported contained IDFA but not ATT. For example, an app having SDK V5.X on a device having iOS 14
af_unavailable
  • ATT was not reported in the event by the advertiser and IDFA is not available.
  • AppsFlyer SDK version V5.X is unable to get ATT and did not get IDFA
