Terms of Use
Plain-language terms for using [SITE NAME], a free calculator site. By using this site, you agree to the terms below.
Using the site
[SITE NAME] provides free online calculators for informational and educational purposes. Every calculator is free to use, with no account, sign-up, or payment required, ever. You may use the site and its tools for personal or professional reference.
Age requirement
This site is intended for a general audience and is not directed at children. You must be at least 13 years old to use this site on your own. This requirement exists to comply with children's online privacy laws (such as COPPA in the United States) that place special obligations on websites when children under 13 may be using them - it isn't a reflection of anything specific to how this site is used. If you are under the age required by your local law to agree to these terms on your own, please use this site only with the involvement of a parent or guardian.
Not professional advice
Every calculator on this site produces an estimate based on standard, published formulas and the information you enter - not personalized advice. Results are a starting point for your own research, not a substitute for guidance from a qualified professional (financial advisor, doctor, accountant, engineer, attorney, or other relevant expert) for decisions that matter. We are not responsible for decisions made based solely on a calculator result.
Accuracy of results
We work to keep every formula accurate and every worked example correct, and we welcome reports of any error through our Contact page. That said, we make no guarantee that results are error-free, complete, or suitable for your specific situation. Verify anything important - especially figures involving money, health, or legal matters - independently before relying on it.
No warranty
This site and its calculators are provided "as is" and "as available," without warranties of any kind, express or implied, including but not limited to accuracy, reliability, uninterrupted availability, or fitness for a particular purpose. Use of the site is at your own discretion and risk.
Limitation of liability
To the fullest extent permitted by law, [SITE NAME] and its operators are not liable for any indirect, incidental, special, or consequential damages arising from your use of, or inability to use, this site or its calculators, including but not limited to financial loss, missed opportunities, or decisions made based on a calculation result - even if we have been advised of the possibility of such damages.
Acceptable use
Please don't use this site to: attempt to disrupt, hack, or overload the site or its infrastructure; scrape or systematically extract content for republishing elsewhere; use any tool (including the generator tools) for an illegal purpose; or attempt to bypass any rate limits or security measures.
Intellectual property
The site's design, original written content, and the specific code implementation of each calculator are owned by [SITE NAME] unless otherwise noted. The underlying mathematical formulas themselves are standard, publicly known methods and are not owned by us. You're welcome to link to any page on this site; please don't republish our written content or code elsewhere without permission.
Third-party links and services
Some calculators rely on third-party services (such as currency exchange rate data) or link to external sites. We aren't responsible for the content, accuracy, or practices of any third-party service or website linked from this site.
Advertising
This site runs on Google AdSense advertising, which is what allows every calculator to stay free with no paywall or subscription. See our Privacy Policy for details on how advertising cookies work.
Termination
We may restrict or discontinue access to the site, in whole or in part, at any time, for any reason, without notice - for example, in response to abuse, excessive automated requests, or violation of these terms.
Severability
If any provision of these terms is found unenforceable, the remaining provisions continue in full effect, and the unenforceable provision will be interpreted to best reflect its original intent within the limits of applicable law.
Entire agreement
These terms, together with our Privacy Policy, constitute the entire agreement between you and [SITE NAME] regarding use of the site, and supersede any prior agreements on this subject.
Changes to these terms
We may update these terms occasionally. Continued use of the site after a change means you accept the updated terms. The "last updated" date at the top of this page reflects the most recent revision.
Governing law
These terms are governed by generally applicable law appropriate to online services and digital agreements, without regard to specific conflict of law principles. If a dispute can't be resolved informally through our Contact page, it will be handled through appropriate legal channels under applicable law.
