Terms of Use
Last updated 2026-10-27.
1. Agreement
By accessing or using calculatormanager.com (the “site”) you agree to these Terms of Use and to the Privacy Policy and Disclaimer. If you do not agree, please do not use the site.
2. The service
The site provides free, browser-based calculators for financial, health, mathematical and everyday calculations, together with explanations, worked examples and cited sources. No account is needed. The calculators run on your own device; nothing you enter is sent to us.
3. Acceptable use
You may not use the site for any unlawful purpose; interfere with or disrupt its infrastructure, including by automated requests at a rate that degrades it for others; scrape or copy its content to build a competing service; remove or alter any copyright or proprietary notice; or present the site's content as your own.
4. Your inputs
You retain all rights to anything you enter into a calculator. Because inputs stay in your browser and are never transmitted to us, we never hold them. You are solely responsible for the accuracy and legality of the information you enter and for any decision you make on the basis of a result.
5. Intellectual property
The CalculatorManager name, logo, design, code, explanations, examples and other original content are owned by the operator of the site. You may use the calculators freely for personal and commercial purposes and link to any page. You may not copy, republish or redistribute the site's text, explanations or code without permission — see Copyright & DMCA. Formulas and published statistics are facts and are not claimed as ours.
6. Results and accuracy
Every calculator shows the formula it applies and cites its sources so that its working can be checked, and results are labelled as estimates. They are information, not financial, tax, investment, medical, legal or other professional advice. Always verify a result before relying on it for any decision that matters, and consult a qualified professional where appropriate.
7. Availability
The site is provided free of charge and “as is”. We do not guarantee that it will be available without interruption, and we may modify, suspend or discontinue any part of it at any time without notice.
8. Third-party links
Pages link to external sources such as government agencies and regulators. We are not responsible for the content, accuracy or practices of any external site.
9. Disclaimer of warranties
To the fullest extent permitted by law, the site and its calculators are provided without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy or non-infringement.
10. Limitation of liability
To the fullest extent permitted by law, the operator of the site shall not be liable for any indirect, incidental, special, consequential or punitive damages, or any loss of profits, data or goodwill, arising from your use of or reliance on the site. Our total liability for any claim shall not exceed the amount you paid to use the site, which is zero.
11. Indemnity
You agree to indemnify the operator of the site against any claim, loss or expense arising from your misuse of the site or breach of these Terms.
12. Changes to these Terms
We may update these Terms from time to time. A material change is reflected in the date at the top of the page; continued use of the site after a change constitutes acceptance.
13. Governing law and jurisdiction
These Terms are governed by the laws that apply to the operator of CalculatorManager.com. Any dispute arising from them will be decided by the courts that have jurisdiction under those laws, except where the consumer-protection law of your place of residence gives you rights that cannot be excluded.
