Last updated: September 19, 2026

These Terms of Service ("Terms") govern your use of NumberLab (numberlab.io), a collection of free online calculators, converters, generators, and simulators (the "Service"). By using the Service, you agree to these Terms. If you do not agree, please do not use the Service.

The Service

NumberLab provides tools across categories such as financial, health, construction, math, networking, programming, vehicle, time and date, weather, academic, agriculture, and electrical calculators, plus unit converters, generators, and interactive simulators. The Service is provided free of charge for general informational and educational purposes.

Not Professional Advice

Results produced by NumberLab's calculators (including but not limited to mortgage, loan, retirement, tax, payroll, BMI, calorie, BAC, pregnancy, and construction material calculators) are estimates for general informational purposes only. They are not financial, medical, legal, tax, engineering, or other professional advice, and should not be relied upon as a substitute for advice from a qualified professional. Always verify important calculations independently and consult a qualified professional before making financial, medical, or safety-related decisions.

No Warranty

The Service is provided "as is" and "as available," without warranties of any kind, express or implied, including accuracy, completeness, reliability, or fitness for a particular purpose. We do not guarantee the Service will be uninterrupted, error-free, or available at all times.

Limitation of Liability

To the fullest extent permitted by law, NumberLab and its operator shall not be liable for any indirect, incidental, special, or consequential damages, or for any loss of data, revenue, or profits, arising from your use of, or inability to use, the Service or reliance on any result it produces.

Acceptable Use

You agree not to: interfere with or disrupt the Service or its infrastructure; attempt to bypass security controls; scrape or automate requests in a way that places excessive load on the Service; or submit unlawful, harmful, or malicious content through any form on the Service.

We are not responsible for the content, availability, or privacy practices of any third-party site or service.

Intellectual Property

The NumberLab name, design, and original content are owned by NumberLab. Third-party libraries used by the Service remain the property of their respective owners and are used under their own open-source licenses.

Changes to the Service or Terms

We may modify, suspend, or discontinue any part of the Service at any time, and may update these Terms from time to time. Continued use of the Service after changes are posted constitutes acceptance of the revised Terms.
