Signed out, nothing about you leaves this browser: your palette and personal bests live in local storage here.

Signing in stores the id your OAuth provider gives us, the email address it reports, your display name, your chosen avatar — and, as you play, your settings, saved themes and the game results behind your private stats. Nothing is shared with anyone else, and there is no advertising or tracking attached to any of it.
