Cookies and local storage

One thing: whether you prefer the site in light or dark mode. It is saved in your browser’s local storage so the site remembers your choice next time. It is not a cookie and it is not sent to us.

This site does not set advertising or analytics cookies, does not build a profile of your browsing, and does not follow you to other websites.

You can clear this preference at any time by clearing site data in your browser. The site will simply ask your system what it prefers next time you visit.

If we ever add measurement tools to the site, we will say so on this page before we do it.
