The calculators

Every calculator on this site runs entirely in your browser. The numbers you type — volumes, position sizes, entry prices — are never sent to a server, never stored and never seen by us. Close the tab and they are gone.

The contact form

If you write to us we store what you submit: name, email, country, the options you selected, your message, the page you sent it from, your IP address and browser identifier. The last two exist to block spam floods. We use all of it for exactly one purpose — replying to you — and we do not sell it, rent it or pass it to Binance.

No file uploads are accepted anywhere on this site.

In your browser

We store your theme choice, and whether you dismissed the language suggestion, in local storage. Neither ever leaves your device. We never redirect you by language. If your browser prefers one of our other languages, a dismissible line offers the link and you decide; the address never changes on its own. This site sets no cookies at all. The service worker caches pages you have already visited so the site works offline; that cache is yours and is cleared with your browsing data.

Third parties

When you click a referral link you leave this site and Binance's own privacy policy applies from that point. We receive aggregate referral statistics from Binance — how many accounts registered — never your identity, balance or trades.

Write to contactmail.bsam@gmail.com to see what we hold about you or to have it deleted. We will act on it and confirm.
