I respect your privacy, so I don't use anything like Google Analytics or similar services. In fact, there is no JavaScript at all on this site. My CDN provider does collect basic metrics on what pages get accessed, and some other information you send in your request.

I am never presented this information in a non-aggregated form, meaning that when you access this site I get some metrics that can help me optimize the site for you, but I can't see any of your information specifically.

This information is based off of data in the requests you make to the site, like your user agent and IP address. To my knowledge it's mainly used by CloudFront to help mitigate DoS attacks or perform region blocking. If you want to block it, feel free.
