Privacy Policy

Last updated: September 29, 2026

This policy covers ui.half-built-robots.com, the reference site for the @half-built packages. The site is owned by Curt Henrichs LLC, a California LLC. It is a static site with no accounts, forms, comments, or ads, and it collects almost nothing.

What the site collects

The site is hosted by Cloudflare. Like nearly every host, Cloudflare may keep standard request logs (IP address, browser type, and the pages requested) as part of serving the site.

The site uses Cloudflare Web Analytics to count page views. Cloudflare adds a small script to each page for this. It sets no cookies, stores nothing in the browser, and does not follow visitors to other sites. The result is a tally of which pages were viewed.

Cookies and browser storage

The site sets no cookies of its own. Cloudflare runs bot protection in front of the site, and that sets one cookie, cf_clearance. It records that the browser already passed Cloudflare's check, so it is not challenged again. It lasts up to a year, only Cloudflare can read it, and it is not used for ads or cross-site tracking.

The site also keeps a few small values in the browser's local storage. None of it is sent anywhere and none of it identifies anyone.

  • hbui-demo-theme: the light or dark mode choice, saved when the theme toggle is used.
  • hbui-palette: the colors picked in the palette editor, saved so the page keeps them on reload.
  • half-built-ecosystem: a copy of the footer's list of related sites, kept for a day so it is not fetched on every page. The list comes from ecosystem.half-built-robots.com, which is also run by Curt Henrichs LLC on Cloudflare.

Clearing the browser's data for this site removes all of it.

Do Not Track

Nothing on this site tracks visitors across other sites, so it behaves the same whether or not the browser sends a Do Not Track or Global Privacy Control signal. There is nothing for the signal to turn off.

Why it is kept and for how long

  • Cloudflare's logs, analytics, and bot protection. These keep the site running and protected. Cloudflare keeps them on its own schedule under Cloudflare's privacy policy.
  • Email sent to the contact address. It is used to answer the sender, and it is kept unless the sender asks for it to be deleted.

Where it is processed

Cloudflare and Google are United States companies, so anything they hold for this site is processed in the US. Cloudflare takes part in the EU-US Data Privacy Framework.

Links to other sites

The site links to GitHub, npm, and Half-Built Robots. Their privacy practices are their own; this policy covers only this site.

Children

This site is not directed at children under 13 and does not knowingly collect personal information from anyone under 13.

Your data

Anyone, wherever they live, can ask what this site holds about them. They can also ask to have it corrected, deleted, or sent to them as a copy, or ask for it not to be used. Write to the address below. The site itself holds nothing about its visitors, so the answer is almost always nothing.

Anyone who thinks a request was handled badly can complain to the data protection authority where they live.

Changes

Updates to this policy are posted on this page with a new date at the top.

Contact

The email address is a Gmail account, so mail sent to it is also handled by Google under Google's privacy policy.
