This blog is served by hardware run and owned by me. The only information I see about you, the visitor is whatever your browser sends as part of the connection. That usually includes the IP address visible to my hardware, the user agent string which identifies your browser, and a few other HTTP headers. Log files are rotated frequently so nothing is stored for more than a few weeks.
I do parse the logs with goatcounter and send them to a self hosted instance because I like to see which pages and posts are popular and where my readers come from. All information is aggregated so nothing can be used to identify any specific users.
Aside from that I have taken great care to eliminate any other external dependencies that could be used to track you. No external scripts or assets are loaded.
