The terms on which you may use onlinecalculatorsite.com. By using the site you accept them.
Using the site
You may use these calculators freely, for personal or commercial purposes, without charge or attribution. You may not copy the site wholesale, scrape it systematically, or republish the calculators as your own.
You must not use the site in any way that damages it, interferes with other people using it, or breaks the law.
No guarantee of accuracy
The calculators are provided as they are. We take care over them and check them, but we do not warrant that every result is accurate, complete or current, and the site may be unavailable at times without notice.
Not professional advice
Nothing on this site is financial, tax, legal, medical or structural advice. The results are estimates to help you think, not a basis for a decision that matters.
A tax calculator cannot see your full circumstances. A health calculator is not a diagnosis. A construction calculator is not a substitute for a structural engineer. For anything with real consequences, speak to a qualified professional.
To the extent the law allows, we accept no liability for any loss arising from reliance on a result from this site.
Links to other sites
Where we link elsewhere, it is because we think the destination is useful. We do not control those sites and are not responsible for their content or their handling of your data.
Changes
We may change these terms. The version on this page is the one that applies, and the date below shows when it last changed.
Law
These terms are governed by the law of England and Wales.

Written in plain English rather than by a solicitor. If the site grows into something commercially significant, have it reviewed properly.
