These terms describe how the free calculator and math-resource site may be used.
By accessing and using mathcheck, you agree to be bound by these Terms of Service. If you do not agree, please do not use the service.
mathcheck provides free online calculator tools, unit conversion utilities, formula references, and educational math guides. The service is provided as-is for educational and personal use.
You agree to use mathcheck only for lawful purposes and in accordance with these Terms. You may not attempt to interfere with the proper functioning of the service, attempt to gain unauthorized access to any systems, or use automated tools to scrape or overload the service.
mathcheck may display clearly labeled ads or sponsored links on eligible public pages. Ads do not change calculator results and are not endorsements by mathcheck. Do not click ads to support MathCheck, test ad behavior, or create artificial traffic.
All content, design, and code on mathcheck is the property of mathcheck or its licensors. You may use the tools for personal and educational purposes but may not reproduce, distribute, or create derivative works from the site content without permission.
mathcheck is provided "as is" and "as available" without warranties of any kind. While we strive for accuracy, we do not guarantee that calculations or conversions will be error-free. Always verify important calculations independently. The site does not provide professional financial, legal, tax, medical, construction, or health advice.
To the fullest extent permitted by law, mathcheck shall not be liable for any indirect, incidental, or consequential damages arising from your use of the service.
We reserve the right to modify these Terms at any time. Changes will be posted on this page with an updated date. Continued use of the service after changes constitutes acceptance.
