Summary: I don't track, but there are a few scripts/services on this site.

Comments are handled by Giscus, and to comment you must sign in to it with Github. Once commented, you can manually remove your comments by editing your posts on https://github.com/CodeDrivenDevelopment/comments.

Analytics with Google Analytics, to track number of visitors on the site

I also use Sentry to track javascript errors on this site, but set it up to not collect IP addresses or other personally identifying information (PII)
