We use the information from Google Analytics only to improve our Service. Google's ability to use and share information collected by Google Analytics is restricted by the Google Analytics Terms of Service and the Google Privacy Policy. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.
