What we use

This site uses no analytics, advertising or third-party cookies, and loads nothing from other domains (fonts are served from this site).

Theme preference

If you choose light or dark mode, we keep that choice in your browser's local storage to remember it. You turn it on yourself, and it is never sent to any server. You can clear it from your browser.

The app

The PrismaMath app uses the technical cookies it needs to keep you signed in and to protect its forms. They are described in its own policy.
