Everything this site knows about you. There's no account system, no analytics vendor, and no server-side record of your visit — so the list is whatever your browser tells any page that asks, plus the two localStorage keys we write ourselves.

Every field above is available to any page you load, without permission — which is roughly the point. Fingerprinting works by combining a few dozen of them into something unique. Nothing here is sent anywhere; open the network tab and check.

You can wipe both storage keys any time from /learn/progress and /eggs.
