All calculations run in your browser. There is no account, no server-side storage and no connection to any exchange.

• We do not collect your capital, prices, lot sizes or any other trade numbers.
• Usage statistics, once enabled, record only coarse events (for example “a calculation succeeded”, the contract and a leverage range) — never amounts. The analytics provider will be named here before it is switched on.
• Your light/dark theme choice is stored in your browser's local storage.
