To use the add-on, users automatically submit the urls they have been on (RateTheSite does not read the website source code). This helps with logging to prevent spam on our servers and conduct analysis of websites to provide better objective recommendations for users in the future. URLs are inherently not a place website developers store harmful information, and the only urls transmitted are the ones not disallowed via a robots.txt listing or essentially what you see in your browser's url address bar. If the user logs in with Google, the user agrees to Google's OAuth authentication services. By logging in with Google, users may add ratings on each website they visit.
