Without an account
You can play every quiz without signing in. Your progress and settings are stored in your own browser (local storage) and are not sent to us.
We count visits with Plausible Analytics, which does not use cookies and does not collect personal data. It records things like the page, referring site, country and device type, plus quiz events such as starting a quiz or finishing a sprint.
With an account
If you sign in, we store your email address (or the email of the Google account you use), the leaderboard name you choose, the places you have found in each quiz, and your sprint scores. Accounts are run on Supabase, which stores this data on servers in the United States.
Your leaderboard name and scores are public on the leaderboards. Your email address is never shown to other players.
We use your email only to sign you in. We do not sell or share it.
Deleting your data
Sign in, open your account (top right) and choose Delete my account. This removes your email, name, progress and scores immediately. To clear progress saved in your browser, clear this site’s data in your browser settings.
Map and data sources
Map tiles come from OpenFreeMap (OpenStreetMap data), which receives your IP address when your browser requests tiles. Boundaries and population figures come from the U.S. Census Bureau.
