    With the release of iOS 14 some <a href="https://www.apple.com/ios/ios-14/features/#Privacy" target="_blank">Privacy</a> features are put into the spotlight.
    One of these features is making transparent how your data is being used for tracking purposes.
    Developers are now required to self-report their privacy practices.
  </p><p>
    We have selected a random sample of applications for evaluation and want to check whether the app behaviour changes over time.
    This study consists of two stages; this is the second.
    In the first stage we recorded the app communications before iOS 14 was released.
    In the second stage we repeat the process after the launch of iOS 14.
  </p><p>
    You can help us by providing app recordings of the following applications.
    Make sure to update to the lastest AppCheck version (v.34) which includes a check for the iOS version.
