Privacy policy

The short version: your financial inputs never leave your browser. All calculations run locally on your device. We do not see, collect, store, or transmit the numbers you enter.

What we do collect

Standard anonymous web analytics (page views, approximate region, device type) to understand which pages are useful. This data is aggregate and cannot identify you.

Share links

The "Share" button encodes your inputs into a URL on your device so you can send a scenario to someone. That URL exists only where you choose to send it — we don't log it.

Cookies and advertising

If advertising is enabled on this site, ad providers may use cookies subject to their own policies, and any consent options will be presented as required by your region. We do not sell personal information.
