Privacy Policy

Last updated: August 16, 2026.

A plain-language description of what this site actually does with data, not formal legal counsel.

What This Site Collects

Nothing directly. There are no comments, no contact forms, no newsletter signup, and no accounts on this site.

Third-Party Services

A couple of embedded services can see that your browser loaded a page here, as an ordinary side effect of how they work:

• Google Fonts — this site loads typefaces (IBM Plex) from Google’s font service (fonts.googleapis.com, fonts.gstatic.com), which means your browser makes a request to Google when you load a page, and Google can see your IP address as an ordinary side effect.
• Embedded X (Twitter) posts — a number of articles and reference pages across the site embed real X posts using X’s own widget script. X’s own cookies may apply, per X’s privacy policy, independent of anything this site does.
• KaTeX (math rendering) — every page on this site loads a math-typesetting library from cdn.jsdelivr.net so formulas render correctly. This is a static script/stylesheet — jsDelivr can see that your browser requested it, the same ordinary side effect as the Google Fonts request above.
• Embedded YouTube videos — a few pages embed YouTube videos, which load YouTube’s own player and can set YouTube/Google cookies per their privacy policy.

Neither of these is an analytics or advertising tracker — this site runs no ad network and no visitor-tracking analytics of its own.

What The Server Records

Like nearly every web server, this one keeps an access log: the page requested, the time, your IP address, and your browser’s user-agent string. It’s used to see whether the site is working and roughly how much it’s being read. Logs rotate and are deleted automatically after a few days. They are not sold, not shared, and not linked to anything else.

Links to Other Sites

This site’s footer links to AdBlob (adblob.com), a separate site I also run, which does contain affiliate links. Following that link takes you to AdBlob’s own privacy policy, not this one — see its Affiliate Disclosure and privacy pages there.

Changes

If what this site collects or how it’s handled changes, this page gets updated at the same time.
