> To address your concern with the privacy, WhatRuns do not collect or log any visitor information including IP address, location etc

That's not the whole truth - you are using Google Analytics to track visitors and you fail to disclose this in your privacy policy, despite this being mandatory under the Google Analytics T&C's.

Well done launching what looks like a very cool project, and I hope you can further improve it by informing visitors that you are using Google Analytics to track them (or even drop GA completely in favor of something privacy friendly).
