Privacy

This site has no accounts, no logins, no forms and no cookies, so it shows no cookie banner.
The pages do not run analytics or advertising scripts.
Fonts load from Google Fonts and icons load from unpkg. Those services see your IP address when your browser requests the files, as with any hosted font or icon library.
The language switch on the philosophy page saves your choice in your own browser (local storage). It never leaves your device.
Classroom pieces linked from here check answers inside the browser. A result is sent to a teacher only when a student presses the send button.
The role playing game Terra and the pages hosted by GitHub follow their own hosts' practices.
