Terms of Use
Last updated: July 2, 2026
Free to use
All tools on HatchCalc are free for personal and commercial use. No account or payment is required.
No warranty on results
We work hard to make every calculator and converter accurate, and each tool documents the formula or method it uses. However, results are provided "as is" without warranty of any kind. Always double-check results before relying on them for financial, legal, medical, or other important decisions — HatchCalc is not a substitute for professional advice.
Limitation of liability
To the maximum extent permitted by law, HatchCalc and its operator shall not be liable for any damages arising from the use of, or inability to use, this website or its tools.
Acceptable use
You may not use this site in any way that disrupts its operation, attempts to circumvent security, or violates applicable laws. Automated scraping that places unreasonable load on the site is not permitted.
Changes
We may update these terms from time to time. Continued use of the site after changes are posted constitutes acceptance of the revised terms.
