Privacy Policy

The calculator itself does not collect, store, or transmit anything you type. Every buy/sell entry and every computed result stays in your browser's memory and disappears when you close or reload the page -- there is no server, no account, and no database behind the calculator.

This site may use Google AdSense to show ads, which can set cookies and use device identifiers to personalize ads, subject to Google's own privacy policy. If analytics are added in the future, this page will be updated to describe exactly what's collected.
