This webpage shows your referrer. As simple as that. Your referrer is the page you’re coming from. Why would you want to know your referrer? In other words: Why should we tell you which website you visited just a second ago? This service is mainly used by people who want to test whether their anonymization service or their browser settings work correctly. If you came to this site by clicking on a link on another page and can’t see your referrer above, that means neither we nor other website owners can track your source. You’re one step further on your way anonymity on the internet!
