Apple defines "track" here - https://developer.apple.com/app-store/user-privacy-and-data-use/#permission-to-track: Track user and share it with other companies for targeted advertising or advertising measurement purposes Share user or device data with data brokers So I tries to answer my Crashlytics example question with it: Yes, app privacy information need to state "sharing crash data to other company" for this No, app does not "track" No, ATT only applies those app "track" App review should not reject me, right?

Let's narrow down the question by only focusing on Using Google Crashlytics to collect crash data for debug and 3 yes-no questions of this case. Here's what Apple responses to this, and none responses to this case directly: AppStore Resolution Center If your app integrates code from a third-party partner, like analytics tools, advertising networks, or third-party SDKs, you should include their privacy practices in the App Privacy Information you provide in App Store Connect. For example, if you implement a third-party SDK that tracks users based on data collected by your app, you should disclose that in your app privacy information, and use App Tracking Transparency to request permission to track. If you are unsure if a third-party partner is tracking, please contact them or consult the documentation they've made available. Please note that tracking refers to not just IDFA, but any data that is collected and then used for tracking purposes.

Your responses to the app privacy questions are used to help inform customers about your app’s data practices. Users with the appropriate role must explain your data handling practices in App Store Connect so customers know what data may be collected through your app and how it may be used. Based on your submitted responses, your App Store product page will be updated to include information about the app’s data collection and usage.  Responses are provided at the app level and should represent your app's data practices across all platforms. You are responsible for keeping your responses accurate. If your practices change, update your responses in App Store Connect.
