Privacy policy

Calculator inputs are processed in your browser. We don't ask for your name, address or contact details, and we don't store what you type into the calculators.

Like most websites, our hosting provider may log basic technical information (such as IP address, browser type and pages requested) for security and reliability. We may use privacy-respecting aggregate analytics to understand which pages are useful.

If we add advertising in the future, ad partners may use cookies; we'll update this page before that happens.

If you email us, we use your message only to respond. Questions: feedback@reallyusefulpages.com.
