Terms of use

By using CalcHub (the “site”) you agree to these terms. If you do not agree, please do not use the site.

1. The service

The site provides online calculators, converters and a public API for general information and convenience. We may add, change or remove features at any time.

2. Not professional advice

Results are estimates based on the inputs you provide and standard formulas. They are not medical, financial, investment, tax, legal, engineering or safety advice. Health calculators (for example BMI, calories, blood alcohol or dosage tools) are educational only and must never be used to decide whether it is safe to drive, to treat a condition or to dose medicine. Always consult a qualified professional before making important decisions.

3. Accuracy and availability

We work hard to keep calculators correct, but we do not guarantee that they are error-free, complete or always available. Tax rules, rates, exchange rates and standards change; please check current figures yourself.

4. Acceptable use

• Do not attempt to disrupt, overload or gain unauthorised access to the site or its servers.
• Do not use automated tools to copy the site wholesale. The public API may be used reasonably; we may limit or block abusive use.
• Do not use the site for anything unlawful.

5. Accounts

You can create an account (including by signing in with Google) to save results. You are responsible for keeping your login details secure and for activity under your account. We may suspend or delete accounts that break these terms.

6. Content and intellectual property

The site's design, text, code and data belong to CalcHub or its licensors. You may use calculator results for your own personal or business purposes, and link to our pages freely. You may not republish or resell the site's content without permission.

7. Advertising and third-party links

The site may show advertising and link to third-party websites. We do not control and are not responsible for third-party content, products or services.

8. Disclaimer of warranties

The site is provided “as is” and “as available” without warranties of any kind, express or implied, to the maximum extent permitted by law.

9. Limitation of liability

To the maximum extent permitted by law, CalcHub is not liable for any indirect, incidental or consequential loss, or any loss arising from your reliance on the calculators or from site downtime. Nothing in these terms limits liability that cannot be limited by law.

10. Changes to these terms

We may update these terms from time to time. Continued use of the site after a change means you accept the updated terms. The date above shows the latest revision.

11. Privacy

How we handle information is explained in our Privacy policy.
