Terms of Use

01Who we are

This website is operated by Tuff Search (tuffsearch.com). Contact: support@tuffsearch.com.

02Use of the calculators

You may use our calculators free of charge for personal, educational and general business purposes. Results are estimates for information only and are not medical, financial, tax, legal, engineering, veterinary or other professional advice. Please read our Disclaimer.

03Accuracy

We base calculators on published formulas and official sources and test them before publishing, but we cannot guarantee that every result is correct, complete or up to date for your situation. Results depend on the values you enter and the assumptions explained on each page. Check important results independently or with a qualified professional.

04Acceptable use

You agree not to:

• use the site for any unlawful, harmful or fraudulent purpose;
• attempt to gain unauthorised access to the site, its servers or systems, or disrupt their operation;
• scrape or copy the site or its calculators in bulk using automated tools without our written permission;
• upload or transmit malware or other harmful code;
• present our calculators or content as your own, or misrepresent results in a way that could mislead others;
• click on advertisements in a way that is not genuine, or encourage others to do so.

05Intellectual property

The website's text, design, graphics, logo, the Tuff Search name and the software code of our calculators are owned by Tuff Search or its licensors and are protected by copyright and other laws. Mathematical formulas and publicly available standards are not owned by anyone; our specific implementation, explanations and design are.

You may link to any page on Tuff Search and quote short extracts with attribution and a link. Any other reproduction, republication or embedding needs our written permission (partnerships@tuffsearch.com).

10Limitation of liability

To the fullest extent permitted by law, Tuff Search and its team are not liable for any indirect, incidental or consequential loss, or for any loss arising from decisions made using calculator results. Nothing in these Terms limits liability that cannot be limited by law.

11Changes

We may update these Terms. The updated version will be posted on this page with a new 'Last updated' date. Continued use of the site after changes means you accept the updated Terms.
