Privacy policy

The math runs entirely in your browser. Your win rate, account size and risk figures are never sent to a server to be calculated, and no result is ever stored against you.

One honest exception: the session recording tool described below captures what happens on the page, and that includes text typed into the calculator fields. So while nothing here asks who you are, a recording of your visit can show the numbers you tried. If that bothers you (and it's a reasonable thing for it to bother you), the opt-out section below turns it off.

That's the complete list. There are no ad networks, no data brokers, no third-party trackers beyond the three above, and nothing here is ever sold.

Some outbound links to prop firms carry a tracking parameter so the firm knows the visit came from here — that's how the site is funded, and the disclosure at the foot of every page says so.

Once you land on the firm's site, that firm sets its own cookies under its own privacy policy, and I have no visibility into what you do there beyond eventually being told that a referral converted. I never receive your name, your email or your account details from them.

None of the tools above load until you accept them. On your first visit you get a banner with two buttons; decline and nothing is loaded, on that visit or any later one. Your answer is stored in your browser, not on a server.

Changed your mind either way? Clear this site's data in your browser and the banner comes back on your next visit, so you can answer again.

If you would rather not rely on that, any of these also works:

• A content blocker such as uBlock Origin — it blocks all three tools outright.
• Your browser's tracking-protection setting, or Global Privacy Control if your browser supports it.
• Google's official opt-out browser add-on, for Analytics specifically.
• Clearing cookies for this domain, which resets any identifier held for you.

None of it changes what the site does. Every calculator works fully either way.

If you're in the EU or UK you have the right to access, correct, delete, restrict or object to the processing of your personal data, to data portability, and to complain to your national data protection authority.

The practical limit is worth saying out loud: because nothing here is tied to a name or an email, I usually have no way to identify which anonymous records are yours, so I can't reliably fulfil an access or deletion request against them. The controls in the section above are the effective route — they stop the collection at the source.

Data is kept for as long as the analytics tools' retention settings hold it — event data in Analytics for the retention period set on the property, session recordings in PostHog for the period covered by our plan — after which it is deleted automatically.

This site is about leveraged trading and is intended for adults. It isn't directed at anyone under 18 and I don't knowingly collect anything from them.

If the tools above change, this page changes with them and the date at the top moves. There's no version history to dig through — what's here is what's running.
