Google sign-in gives us a name, email, and profile image so we can keep your credits and positions. Dev sign-in, when switched on, uses a local cookie and no Google account.
Trades, ledger rows, and leaderboard snapshots stay in the database. Public profiles show a name and open positions. You can hide your profile. Page paths are counted so we can see which screens are used. We do not sell that.
Turnstile, when configured, sends a token to Cloudflare to check that a trade came from a person. Stripe, when configured, handles the card payment and we store only the credit grant.
