Privacy policy

Your figures never leave your device. All calculations run in your browser. The numbers you enter are stored only in your browser's localStorage and are never transmitted to or stored on any server.

Share links. If you use “Copy link”, your inputs are encoded into the URL so the recipient can load them. Anyone with that link can see those figures — only share with people you trust. We never log share-link contents.

Analytics. We use privacy-first, cookieless analytics that records anonymous page views and feature usage only — never your financial figures and never personal identifiers. This means no cookie-consent banner is required.

Your control. Clear your data any time from your browser, or use export/import to back it up. Because we hold no personal data on a server, there is nothing for us to delete on your behalf.
