This page explains what information this website collects and how it is used. It was last updated in June 2026.

Calculator inputs

The numbers you type into the calculator are processed entirely in your browser to produce your results. They are not transmitted to us or stored on any server. When you close the tab, they are gone.

Cookies and local storage

The calculator itself does not require cookies to function. However, this site uses third-party services that may set cookies, as described below. Your browser settings let you block or delete cookies at any time, though doing so may affect how some third-party features behave.

Analytics

We use privacy-friendly, aggregate web analytics to understand how many people visit and which pages are useful. This data is collected in aggregate and is not used to identify you personally.

Advertising and third-party vendors

This site may display advertising served by third-party vendors, including Google. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet. You can opt out of personalized advertising by visiting Google's Ads Settings, and you can learn more about how vendors use cookies through the Network Advertising Initiative opt-out page. Third-party vendors and ad networks may also place and read cookies on your browser, or use web beacons to collect information, as a result of ad serving on this website.
