title: Is my app or its dependencies violating the Android Advertising Id policy?
body: <p>I've just received this message from Google Play but I'm not collecting the Advertising ID.</p>
  
  <blockquote>
    <p>Reason for warning: Violation of Usage of Android Advertising ID
    policy and section 4.8 of the Developer Distribution Agreement</p>
    
    <p>Google Play requires developers to provide a valid privacy policy when
    the app requests or handles sensitive user or device information.
    We’ve identified that your app collects and transmits the Android
    advertising ID, which is subject to a privacy policy requirement.</p>
