The documents linked below set out the legal framework for using the Site — including how we handle personal information, how advertising and cookies work, what you can and cannot do with our content, and the limits of what our calculators are designed for.

Our policies
Who runs Calculator Friendly
Calculator Friendly is operated by a small independent team. Each calculator we publish is researched, implemented against trusted reference formulas and reviewed for clarity before it goes live. You can read more about the people and process on our About page and our Editorial Policy.
How we make money
The Site is free to use. To keep it that way we display advertising, including ads served by Google AdSense and other ad networks. Advertising never influences our calculators or the way we explain results. The Privacy Policy and Cookie Policy describe the cookies and data flows involved, and you can change your consent at any time using the "Cookie preferences" link in the footer.
