  • This site has no accounts, no comments and no forms.
  • It sets no cookies of its own. Your light or dark choice is stored in your browser only.
  • It currently runs no analytics and no advertising.
  • The site is hosted on Cloudflare Pages. Cloudflare, like any host, sees your IP address and the pages you request, and keeps ordinary server logs. See Cloudflare's privacy policy for details.
  • Code you type into the Python runner stays in your browser.

If I add advertising or analytics later, I will change this page first and say what is collected and by whom.
