Terms of Use

Last updated: October 5, 2026. By using CalcMate you agree to these terms.

1. The service

CalcMate provides free browser-based calculators for general information and education. We work to keep formulas accurate and tested, but we make no guarantee that any result is error-free or suitable for your situation.

2. Not professional advice

Calculator outputs are not financial, medical, legal, or tax advice. Health tools (BMI, calories, body fat, due date) are estimates, not diagnoses. Money tools don't account for taxes, fees, or your personal circumstances. Consult a qualified professional before acting on any result.

3. Acceptable use

• Use the tools for lawful purposes only.
• Don't attempt to disrupt the site, scrape it aggressively, or misrepresent its outputs as professional advice.
• You may link to our pages and share results; don't copy substantial content without permission.

4. Intellectual property

CalcMate's design, text, and code are our property (or used with permission). Formulas themselves are public mathematical knowledge.

5. Third-party links and ads

We may display third-party ads (e.g., Google AdSense) and link to external sites. We're not responsible for their content, accuracy, or privacy practices.

6. Limitation of liability

To the maximum extent allowed by law, CalcMate is provided “as is” without warranties. We are not liable for decisions you make based on calculator outputs, or for any indirect or consequential damages.

7. Changes

We may update these terms; continued use after changes constitutes acceptance. If you don't agree, please stop using the site.
