Google asks every app to have a Privacy Policy to be accepted in the Play Store. So, xScreenSaver had to write a privacy policy.

@fla w.r.t. the line:
Unlike Google, XScreenSaver will never tell you to put glue on pizza, eat rocks, or smoke while pregnant.

I think you might want to reconsider.
Screenshots of google saying these things could be quite funny and a good screensaver.
