# App Tracking Transparency

Starting with iOS 14.5 publishers have to use the [App Tracking Transparency](https://developer.apple.com/documentation/apptrackingtransparency?language=objc) framework when accessing the IDFA. This is why you should present the app-tracking authorization request to the end user. Currently Unity doesn't officially support this functionality, however, there is a preview package allowing to use ATT framework. Please see [this](https://alanyeats.com/post/unityapptrackingtransparencypopup/) article to find out how to use it within your project. Also please see our recommendations [here](https://bitbucket.org/addapptr/addapptrlandingpage/wiki/iOS14).
