Cookie policy.

A short, plain-English account of the small number of cookies this site uses. We try to use as few as we can. We do not run advertising. We do not use marketing trackers.

In short

  • This site uses two essential storage entries and (optionally) one analytics cookie.
  • Essential storage cannot be turned off — the site needs it to remember your cookie choice.
  • Analytics is anonymous and aggregated. You can decline it via the cookie banner.
  • You can clear your cookie choice at any time by clearing your browser’s storage for this site.

What is a cookie?

A cookie is a small piece of text a website asks your browser to store, so that the next time you visit the same site the browser can send the text back. Cookies, and the related localStorage and sessionStorage features, are used for things like remembering your preferences or measuring how a site is used.
