Privacy Policy

All calculations run locally in your browser. The numbers you type — trade history, position sizes, portfolio amounts — are never transmitted to or stored on our servers. We do not require accounts and we do not set tracking cookies.

We use your browser's localStorage solely to remember your language preference and to cache the latest price quotes so tools keep working when data feeds are interrupted. Clearing your browser storage removes this data completely.

To display live prices your browser makes direct requests to public market-data APIs (Binance, CoinGecko, open.er-api.com, frankfurter.dev, mempool.space, public Ethereum RPC endpoints). These providers see your IP address like any website you visit; they receive none of your inputs.

If analytics are enabled, they are limited to aggregate page-view statistics (pages visited, approximate region, device type). Calculator inputs are never included.

We may update this policy as the site evolves; the current version is always published on this page. Contact: [email protected].
