Cloudflare's free-tier is being used for DNS and does collect some analytics data. The information I have access to is all anonymous. Matomo (formerly Piwik), Countly, and/or Fathom may be used for analytics, with IP Anonymization enabled and Do Not Track support enabled. All analytics software will be self-hosted and any collected data will never be sold.
I collect as little identifiable information about you as I can. I do not have any tracking logic beyond what I highlighted above installed on this site.
