5. 1.2 Legal: Privacy - Data Use and Sharing

Guideline 5.1.2 - Legal - Privacy - Data Use and Sharing

We noticed you do not use App Tracking Transparency to request the user's permission before tracking their activity across apps and websites. The app privacy information you provided in App Store Connect indicates you collect data in order to track the user, including Performance Data, Crash , Advertising Data, Product Interaction, and Other Diagnostic Data.

Starting with iOS 14.5, apps on the App Store need to receive the user’s permission through the AppTrackingTransparency framework before collecting data used to track them. This requirement protects the privacy of App Store users.

Next Steps

Here are two ways to resolve this issue:

You can remove the tracking functionality from your app and update your app privacy information in App Store Connect.

If you decide to continue tracking users, you must implement App Tracking Transparency and request permission before collecting data used to track the user or device.

ATT(Application Tracking Transparency)란?

iOS 14.5, iPadOS 14.5, tvOS 14.5 이상에서는 사용자를 추적하거나 사용자 기기의 광고 식별자에 액세스할 때 AppTrackingTransparency 프레임워크를 통해 사용자 권한을 얻어야 합니다. 추적은 앱에서 수집한 사용자 및 기기에 대한 데이터를 타겟 광고 및 광고 효과 측정을 위해 타사 앱, 웹사이트 또는 오프라인 속성에서 수집한 사용자 및 기기에 대한 데이터에 연결합니다. 행위를 가리킵니다. 또한 사용자 및 기기에 대한 데이터를 데이터 브로커에 공유하는 것도 추적에 적용됩니다.
