Privacy Policy

The calculators on this site run entirely in your browser. The numbers you enter are never sent to, or stored on, our servers.

If you accept analytics cookies, we collect anonymous usage statistics through Google Analytics 4 — pages viewed, calculators used and buttons clicked. These records contain no personal information, no account details and nothing you type into a calculator.

Separately from the cookie choice below, we use Vercel Web Analytics and Speed Insights to count page views and measure how fast pages load. They set no cookies, store nothing on your device, and do not identify you or follow you across other websites, so they run without the notice.

Analytics is optional and off by default. A small notice appears when analytics is available; if you dismiss or decline it, no analytics script is loaded and no analytics cookie is set.

Your choice is remembered in your browser (local storage) and you can clear it at any time from your browser settings.

We do not sell or share personal data, because we do not collect it.

If you email us, we use your address only to reply to you.

Some pages link to external websites such as brokers. Those sites have their own privacy policies, which we encourage you to read before providing them with any information.
