I&#39;ve just received this message from Google Play but I&#39;m not collecting the Advertising ID.

&gt; Reason for warning: Violation of Usage of Android Advertising ID
&gt; policy and section 4.8 of the Developer Distribution Agreement
&gt; 
&gt; Google Play requires developers to provide a valid privacy policy when
&gt; the app requests or handles sensitive user or device information.
&gt; We’ve identified that your app collects and transmits the Android
&gt; advertising ID, which is subject to a privacy policy requirement.
