Calculator data
We do not store calculator inputs in cookies or localStorage by default. The calculator does not require your name, email address, firm login, account number, or trading credentials. Keep sensitive account details out of any notes or files you choose to share.
Saving and copying
Clicking Save downloads a results file to your own device. You control where that file is kept and who can see it. Clicking Copy writes the selected result to your clipboard; this happens only when you request it. Neither action uploads your figures to us.
Hosting requests
Cloudflare hosts and delivers this website. Normal website requests may involve an IP address, request time, browser information, and other request metadata processed by the hosting service. This is separate from the profit values used locally by the calculator.
This release has no installed Google Analytics 4 or advertising trackers. The site does not offer account registration, a newsletter subscription, or a form collecting personal details.
External sites
Official rule and firm links open third-party websites. Their own privacy policies and storage practices apply when you visit them. Read the about page for the tool's scope and the methodology for how source links are used.
