Terms of Service

1. Acceptance of these terms

Accessing or using this website constitutes acceptance of these Terms of Service and of our Privacy Policy. If you do not agree with any part of them, please discontinue use of the site.

We may revise these terms from time to time. The revision date shown above always reflects the current version, and continued use after a change constitutes acceptance of the revised terms.

2. Permitted use

You may use the calculator and the accompanying articles for personal, educational and commercial purposes, including in coursework, workshop documentation and professional calculations.

You may not scrape the site at a rate that degrades service for others, resell access to it, or present it as your own product. Republishing our written explanations requires attribution and a link back to the source page.

3. Accuracy and professional judgement

The solver implements standard, closed-form geometric identities and is tested against known results. Even so, it is an aid to calculation and not a substitute for professional judgement.

Results depend entirely on the values you enter. You are responsible for verifying inputs, units and the suitability of any result before using it in structural, safety-critical, manufacturing or academic work.

4. No warranty

The site is provided on an "as is" and "as available" basis, without warranties of any kind, whether express or implied, including fitness for a particular purpose and uninterrupted availability.

5. Limitation of liability

To the fullest extent permitted by law, we are not liable for any indirect, incidental or consequential loss - including wasted material, rework, lost marks or lost profit - arising from use of, or inability to use, this site.

6. Third-party links

Articles may link to external references. We do not control those sites and are not responsible for their content, accuracy or privacy practices.

7. Governing terms and contact

These terms are governed by the laws applicable at our principal place of business. Questions about them can be sent through our contact page.
