Cookies and tracking
The site sets no cookies, shows no advertising and uses no analytics scripts. Fonts are served from this site, not from a third party.
Hosting
Like every website, the hosting provider receives your IP address and the address of the page you request, so it can deliver the page. It may keep these in server logs for a short time for security and to count visits in total.
Changes
If the site ever adds advertising or analytics, this page will say so before that happens. Last updated: October 17, 2026.
