This site uses Google Analytics to log anonymous data. Like what? Like which pages are visited, when they are visited, and which towns or cities people are (probably) visiting from. It doesn't track things like your name or address, and it can't because your computer doesn't give that out.
It also gives your computer a string of scribbled notes that your computer sends back on each page load. What?
On the internet, clicking a link is like mailing a letter where the return address is a bunch of letters and numbers with no name. People might send mail from different places, and different people may send mail from the same place, which means the website doesn't even know which letters came from the same person. They compensate by giving your computer notes that it must send back with Every. Single. Request. This allows the site to keep track of information such as who has read this message already and which paths people are taking through the site. The string of scribbled notes is called a COOKIE.
