Numbers you enter

Calculators run entirely in your browser. The amounts, filing status and state you enter are not sent to our servers or stored. If you share a result link, the inputs are part of that link.

Error reports

If you use "Report an error", we store your message, the page, the calculator inputs on screen at that moment, your country (from Cloudflare) and, only if you give it, your email address. We use them only to check and fix the reported problem, and delete them once it is resolved. The form is protected by Cloudflare Turnstile, which loads only when you open it.

Hosting and logs

The site is hosted on Cloudflare, which processes standard request data (such as IP address and browser type) to deliver and protect the site.

Analytics and advertising

We do not currently use advertising or tracking cookies. If we add them, this page will be updated first and, where the law requires it, we will ask for your consent.
