I use analytics on this site. It's not Google or anything, it's a self-hosted software called Ackee, and collects minimal information.
I only use analytics to see how many people use the site, and other very basic info such as which pages are the most visited, etc.
If you want to disable it, just block URLs from https://curiosity.termer.net with a browser plugin like uBlock Origin, or just set the domain's IP to something else in your hosts file (if you know how to do that).
