How this site handles your information.
The calculators on this site run entirely in your browser. The numbers you enter are not sent to or stored on our servers.
This site may use basic analytics to see which pages are visited, and may show ads or use affiliate links in the future. If that changes, this page will be updated to explain what is collected and how to opt out.
The site stores one small setting in your browser, your light or dark mode choice, so it can remember it next time.
