App reporting privacy - is there any? When you report an app (for violation) through Google Play, does the developer have access to (any parts of) your Google identity? Does the fact that you've reported this app show up in any of your public (or private) Google records? Does Google have an official policy on that?
There's a pop up every time you submit a report for the privacy policy.

But regardless, pretty much every Google system and API is covered by the same privacy policy:  http://www.google.com/policies/privacy/
