Terms of Use
Acceptance of terms
By using calc.one, you agree to these terms. If you don't agree, please don't use the site. We may update these terms occasionally; continued use after changes means you accept the new version.

No warranty, important
The calculators, content, and other materials on this site are provided "as is" and "as available", without warranty of any kind, express or implied, including without limitation warranties of merchantability, fitness for a particular purpose, accuracy, completeness, or non-infringement. We make reasonable efforts to verify the math but do not warrant that any calculator is free from error or suitable for your particular situation. You should not rely on calc.one calculators for:

To the maximum extent permitted by applicable law, in no event shall calc.one, its operators, contributors, or licensors be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, or other intangible losses, arising out of or relating to your use of the site, its calculators, content, or advertisements, whether based in contract, tort, statute, or any other legal theory, and whether or not we were advised of the possibility of such damages. Some jurisdictions do not allow the exclusion of certain warranties or limitations of liability, so some of the above may not apply to you.
