What you type into the calculators

The calculators run entirely in your browser. The numbers you enter are not sent to us or to anyone else, and they are not saved.

Information we collect

We don't ask for your name, email or any account details, and we don't use cookies.

Like every website, our hosting provider receives standard technical information when your browser requests a page, such as your IP address and browser type. It is used to deliver the site and protect it from abuse.

Third-party services

Our pages load fonts from Google Fonts. When they load, Google receives your IP address and browser details. See Google's privacy policy.

If we add advertising or visitor statistics in the future, we will update this page before doing so and explain what those services collect and how to opt out.

Links to other sites

Some pages link to other websites, such as Costco's. Their privacy policies apply once you leave our site.
