Last updated: October 2026

By accessing or using Tidy Math you agree to these Terms. If you do not agree, please do not use the site.

1. Use of the site

Tidy Math provides free online calculators, converters and educational articles. You may use them for personal and commercial purposes, provided you follow the law and these Terms. You agree not to misuse the site, attempt to disrupt it, scrape it at a harmful rate or interfere with other users.

2. No professional advice

All content is provided for general information and education only. Nothing on Tidy Math is financial, investment, tax, legal, accounting or medical advice, and no professional relationship is created. Calculator results are estimates based on the inputs and assumptions you provide and on simplified formulas. Tax rules, rates and limits change; always verify with official sources and consult a qualified professional before making decisions.

3. Accuracy

We work to keep tools and articles accurate and up to date, but we do not guarantee that they are complete, current or error-free. Currency rates are cached reference values and are not live market data.

The site may display third-party advertising and link to third-party websites. We do not control and are not responsible for their content or practices. See our Privacy Policy.

7. Disclaimer of warranties

The site is provided “as is” and “as available” without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose and non-infringement.

To the fullest extent permitted by law, Tidy Math and its operators will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of profits, data or goodwill, arising from your use of or inability to use the site or from reliance on any calculation or content.

9. Changes and termination

We may modify the site or these Terms at any time. Continued use after changes means you accept the updated Terms. We may suspend access for anyone who violates these Terms.

10. Governing law

These Terms are governed by the laws of the United States and the state in which the site operator is located, without regard to conflict-of-law rules.
