Privacy
27 October 2026
Free play
A free run stays in the browser. The server does not receive the score. Your personal best, games played, and local sats counter are saved in localStorage on that device. Clearing site data removes them.
Nostr login
Ranked play uses your Nostr public key. An extension login is preferred. A pasted private key is saved in that browser's localStorage until you log out, and is NOT sent to the server. The server reads your display name and picture from your public Nostr profile.
Paid runs
A ranked entry is 1000 sats. One payment is one ranked run.
Analytics
Page views are counted with Vercel Web Analytics. Each view records the page address, the site that linked you, your approximate location, and your browser, operating system, and device type. Visitors are counted anonymously without third-party cookies, and a visitor session is discarded after 24 hours. Analytics does not record your Nostr key, your scores, or your payments. See Vercel's analytics privacy notes.
What we do not do
We do not sell this data. We do not ask for your Nostr private key on the server. A share note is signed by your key and posted only if you press the share button.
