Terms of Use
Last updated: April 19, 2026
Plain-English summary
Use the calculators freely for personal or professional reference. Don't rely on them as a substitute for qualified advice. Don't try to break or scrape the site. That's pretty much it.
1. Acceptance of terms
By accessing or using TheCalcUniverse ("the Service"), you agree to be bound by these Terms of Use. If you do not agree, please do not use the site.
We may update these terms from time to time. Changes are effective when posted. Continuing to use the Service after changes are posted means you accept the revised terms.
2. Permitted use
You are welcome to:
- Use any calculator on this site for personal, educational, or professional reference purposes, free of charge.
- Share links to calculator pages or results with others.
3. Prohibited use
You may not:
- Scrape, crawl, or systematically download content from the site in bulk without prior written permission.
- Attempt to reverse-engineer, decompile, or extract proprietary logic beyond what is publicly available in the open-source repository.
- Use the site to distribute spam, malware, or any content that is illegal, harmful, or deceptive.
- Impersonate TheCalcUniverse or imply any endorsement or partnership that does not exist.
- Reproduce the entire site or substantial portions of it under a different brand without permission.
4. Informational purposes only — no professional advice
All results produced by calculators on TheCalcUniverse are for informational and educational purposes only. They do not constitute professional financial, medical, legal, engineering, or any other regulated advice.
- Financial calculators (mortgage, loan, retirement, etc.) produce estimates based on the inputs you provide. Actual loan terms, tax obligations, and investment outcomes will differ. Consult a licensed financial advisor before making major financial decisions.
- Health calculators (BMI, calories, heart rate, etc.) produce general reference values. They are not a substitute for medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional for health-related decisions.
- Engineering calculators produce theoretical values. Real-world applications require proper professional engineering assessment. Do not use results in structural, electrical, or safety-critical designs without independent verification.
By using any calculator on this site, you acknowledge and accept that results are approximate and may not reflect your specific circumstances.
5. Accuracy and availability
We make every reasonable effort to ensure our calculators use correct formulas and up-to-date reference data. However, we make no warranty — express or implied — that results are free of errors, complete, or suitable for any particular purpose.
The Service is provided "as is" and "as available". We do not guarantee that the site will be uninterrupted, error-free, or available at all times. We reserve the right to modify, suspend, or discontinue any calculator or feature at any time without notice.
6. Intellectual property
The design, brand name ("TheCalcUniverse"), original written content, and underlying source code on this site are the property of TheCalcUniverse. All rights are reserved. You may not copy, reproduce, or republish substantial portions of the site or its code without prior written permission.
Mathematical formulas, unit conversion factors, and scientific constants themselves are facts and are not subject to copyright. The implementation, presentation, and curation of those formulas on this site, however, are protected.
7. Limitation of liability
To the fullest extent permitted by applicable law, TheCalcUniverse and its operators shall not be liable for any direct, indirect, incidental, special, or consequential damages arising from your use of or reliance on the Service, even if we have been advised of the possibility of such damages.
This includes — without limitation — financial losses, medical decisions, structural failures, or any other harm resulting from acting on calculator outputs.
8. External links
The site may contain links to third-party websites. These are provided for convenience only. We have no control over and accept no responsibility for the content, privacy practices, or availability of external sites.
9. Governing law
These Terms of Use are governed by and construed in accordance with applicable law. Any disputes arising in connection with the Service shall be handled in accordance with the laws of the jurisdiction in which the operator is based.
