Privacy and Cookies#

This page explains what this site stores on your device and why.

What this site stores#

A theme preference. When you use the light/dark toggle, the site remembers your choice two ways:

  • A mg-theme cookie (shared with magma-maths.org, so the preference carries over between the two sites), and

  • localStorage entries on this site.

Sidebar and table-of-contents state. Whether you’ve collapsed the left navigation sidebar or the right “on this page” panel is remembered in localStorage, so it stays collapsed on your next visit.

Nothing above is set until you actually interact with the relevant control (toggling the theme, collapsing a sidebar) — none of it is set automatically just by loading a page.

What this site does not do#

  • No analytics or tracking cookies.

  • No advertising or third-party embeds.

  • No accounts, logins, or forms that collect personal information.

  • No cross-site tracking of any kind.

This site is verified with Google Search Console, which confirms ownership via a <meta> tag in the page rather than a cookie or script, and does not itself store anything on your device.

Managing this#

All of the above is stored locally on your own device, not on our servers. You can clear it at any time through your browser’s site data or cookie settings — the site will simply fall back to its default appearance.
