Terms of Use

1. Who these terms cover

In these terms, “AllCalcHub”, “we”, “us” and “our” mean the owner and operator of allcalchub.com. “You” means anyone who visits or uses the site, its calculators, tools, explanations, charts and other content (together, the “Service”).

If you are under 18, or under the age of legal adulthood where you live, please use the site with the knowledge of a parent, guardian or teacher, who accepts these terms on your behalf. Children under 13 must use the site with an adult’s supervision.

2. The Service is free and may change

The Service is free and needs no account. We may add, change, suspend or remove any calculator, feature or page, or the whole site, at any time and without notice. We do not promise that the site will always be available, fast or free of interruptions.

3. Results are estimates, not advice

Every calculator is provided for general information, education and planning only. Results depend on the numbers you enter and on the assumptions and formulas each calculator uses, which may simplify real situations (for example a fixed interest rate, standard rounding or average body measurements).

• Nothing on the site is financial, investment, tax, accounting, legal, medical, health, nutritional, engineering, construction or other professional advice, and using the site does not create any professional or advisory relationship with us.
• Do not make a financial, legal, tax, medical or safety decision based only on a result from this site. Check important figures independently and ask a qualified professional who knows your circumstances.
• Health calculators (for example BMI, calorie, pregnancy or dose-related tools) are not medical devices and do not diagnose, treat or prevent any condition. If you think you have a medical emergency, contact your local emergency services immediately.
• Building, engineering and quantity calculators give rough estimates. They do not replace measurements, building codes, manufacturer instructions or the judgement of a qualified tradesperson or engineer.
• School and maths tools are a learning aid. Check your school’s or examiner’s rules before using them for assessed work.

4. Accuracy, and your responsibility to check

We work hard to make the calculators correct and test them against known answers, but we do not guarantee that any result, formula, explanation, rate, rule or other information on the site is accurate, complete, current or suitable for your purpose. Errors, rounding differences, bugs and out-of-date information can happen. You are responsible for checking every result before you rely on it, and you use the site at your own risk.

If you find a mistake, please tell us at allcalchub@gmail.com. We may correct it, but we are not obliged to, and a correction does not mean we accept any liability for the earlier version.

5. Laws, taxes and rules differ by country

Tax rates, interest rules, loan terms, retirement and benefit schemes, health guidance, units, and other laws and regulations differ between countries, states and regions, and they change often. Some calculators mention a particular country’s rules as an example; those figures may be simplified or out of date when you read them.

• The site is not tailored to the laws or regulations of any particular country, state or region, and we do not claim it meets them.
• It is your responsibility to know and follow the laws, regulations and professional rules that apply to you, and to confirm current figures with the official source, such as your tax authority, bank, lender, employer or doctor.
• The site is run from one place and offered to everyone online. We make no claim that it is appropriate or lawful to use in every location. If you use it from somewhere it is not permitted, you do so on your own initiative and are responsible for following your local law.

6. Acceptable use

When you use the site, you agree not to:

• break any law, or use the site for anything fraudulent, harmful or misleading;
• copy, scrape, reproduce, republish, sell, frame or mirror the calculators, text, design or code, in whole or in substantial part, without our written permission;
• reverse engineer the site, or try to get around any security or technical limit;
• overload, disrupt or attack the site, or use bots or automated tools in a way that affects other visitors;
• upload or send viruses or other harmful code;
• click ads deliberately, generate fake traffic, or otherwise interfere with advertising on the site;
• present results from the site as professional advice to others, or suggest that we endorse you, your product or your service.

7. Our content and intellectual property

The site, including its calculators, formulas as implemented, explanations, text, graphics, design, logo, name and code, is owned by AllCalcHub or its licensors and protected by copyright and other laws. Mathematical formulas and facts themselves belong to everyone; our particular expression of them does not. You may use the site for your own personal, study or work purposes, share links to any page, and quote short extracts with a link back to the source page. Any other use needs our written permission.

Some parts of the site use open-source software, which is used under its own licence. If you believe something on the site infringes your rights, email allcalchub@gmail.com with the details and we will look into it promptly.

8. Ads, links and other websites

The site shows ads supplied by third parties, such as Google, and links to other websites, including official sources. We do not control and are not responsible for their content, products, services, accuracy or privacy practices, and a link or ad is not an endorsement. Any dealings you have with an advertiser or other website are between you and them. Our Privacy Policy explains how ads use cookies.

9. No warranty

TO THE FULLEST EXTENT PERMITTED BY LAW, THE SITE AND EVERYTHING ON IT ARE PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED OR STATUTORY. WE DISCLAIM ALL WARRANTIES, INCLUDING ANY WARRANTY OF ACCURACY, COMPLETENESS, RELIABILITY, AVAILABILITY, MERCHANTABILITY, SATISFACTORY QUALITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE AND NON-INFRINGEMENT, AND ANY WARRANTY THAT THE SITE WILL BE UNINTERRUPTED, SECURE, OR FREE OF ERRORS, VIRUSES OR OTHER HARMFUL COMPONENTS.

10. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, ALLCALCHUB AND ITS OWNER, OPERATORS, CONTRIBUTORS AND SUPPLIERS WILL NOT BE LIABLE FOR ANY LOSS OR DAMAGE OF ANY KIND ARISING FROM OR CONNECTED WITH YOUR USE OF, OR INABILITY TO USE, THE SITE, OR YOUR RELIANCE ON ANY RESULT OR INFORMATION ON IT. THIS INCLUDES DIRECT, INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL AND PUNITIVE DAMAGES, AND LOSS OF MONEY, PROFITS, SAVINGS, INVESTMENTS, TAX, DATA, GOODWILL OR OPPORTUNITY, AND ANY PENALTY, FINE, INTEREST OR CHARGE, WHETHER BASED ON CONTRACT, TORT (INCLUDING NEGLIGENCE), STATUTE OR ANY OTHER THEORY, AND EVEN IF WE WERE TOLD SUCH LOSS WAS POSSIBLE.

Because the Service is free, if we are found liable to you despite the above, our total liability for all claims together is limited to the amount you paid us to use the site in the twelve months before the claim, which is normally nothing, or, where the law does not allow that, to fifty US dollars (USD 50) or its equivalent.

11. Your consumer rights

Some countries do not allow certain warranties to be excluded or certain liability to be limited. Nothing in these terms excludes or limits any liability that cannot legally be excluded or limited, such as liability for death or personal injury caused by negligence, or for fraud, or any rights you have as a consumer under the mandatory law of the country where you live. In those places, the exclusions and limits above apply only as far as that law allows.

12. Indemnity

To the extent permitted by law, you agree to defend, indemnify and hold harmless AllCalcHub and its owner and operators from any claim, demand, loss, liability, damage or cost (including reasonable legal fees) brought by a third party that arises from your misuse of the site, your breach of these terms, or your violation of any law or of anyone else’s rights.

13. Ending access

We may block or restrict anyone’s access to the site, without notice, if we reasonably believe they have broken these terms or the law, or to protect the site or its visitors. Sections 3 to 5 and 7 to 16 continue to apply after your use of the site ends.

14. Governing law and disputes

These terms, and any dispute about them or the site, are governed by the laws of the United States of America, without regard to its conflict-of-law rules. The courts of the United States of America have exclusive jurisdiction over any such dispute, except that if you are a consumer, you may also have the right to bring a claim in the courts of the country where you live.

Before starting any formal claim, you agree to contact us at allcalchub@gmail.com and try to resolve the issue informally for at least 30 days. To the extent the law allows, any claim must be brought within one year of when it arose, and only on an individual basis, not as part of a class or representative action.

15. Changes to these terms

We may update these terms at any time. The new version applies from the date shown at the top of this page. Please check this page from time to time; if you keep using the site after a change, you accept the updated terms.

16. General

• These terms, together with the Privacy Policy, are the whole agreement between you and us about the site, and replace any earlier version.
• If any part of these terms is found unenforceable, it is limited as little as needed and the rest stays in full effect.
• If we do not enforce a right straight away, we have not given it up.
• You may not transfer your rights under these terms. We may transfer ours, for example if the site changes ownership.
• If these terms are translated, the English version applies if there is any difference.
