Hi there, we have the same problem at the moment... we will do a detailed description with everything we will track and will hopefully get our new version approved :/ I added this, too: keyNSUserTrackingUsageDescription/key stringOUR DESCRIPTION/string in our info.plist file with the description that looked something like this: We would like to track some of the behavioral Data to improve your experience with our app and the app itself.  We won't pass your data on to somebody else. and it got rejected. I also opened this thread: https://developer.apple.com/forums/thread/679184 because the App Store Review Guys couldn't answer my question, if we have to provide something like a whole new terms of serviec or data privacy terms. We develop our App in Germany, so we already have approved such terms by a lawyer. I really don't hope we have to create another "neck-breaker-text" like this... For usability reasons, I wanted to keep this description short :( Best, Sonja
