Terms of Use

These terms apply to your use of this website and all of its calculators and guides, provided by the WhiteCalc team. By using the site you agree to them. If you do not agree, please do not use the site.

1. The service

The site offers free online calculators and explanatory guides. It is free to use, needs no account and runs in your browser. We may change, add or remove calculators, pages and languages at any time without notice.

2. Results are for reference only

The calculators are tested and checked, but the results are provided for general information and reference. They are not professional advice. Do not rely on them alone for legal, medical, tax, financial, engineering or safety decisions, or for contracts, deadlines and official documents. Check important results with an official source or a qualified professional.

3. Accuracy limits

• Results are rounded to 12 significant digits. Very large or very small numbers are shown in E notation and may lose precision.
• Dates are counted as whole calendar days. Legal and contractual periods may count days differently, for example by leaving out the first day.
• Age is shown as completed years. Some countries and forms use other systems, and a birthday on February 29 is treated as March 1 in years without a February 29.
• Typing mistakes, a wrong angle mode or a misunderstood key can lead to a wrong answer even when the calculator works correctly. Please check what you entered.
• Despite our care, errors are possible. If you find one, please tell us using the contact page.

4. No warranty and limitation of liability

This site and everything on it are provided "as is" and "as available". The WhiteCalc team makes no warranties of any kind, express or implied, including accuracy, completeness, timeliness, fitness for a particular purpose, non-infringement or uninterrupted availability.

To the fullest extent permitted by law, the WhiteCalc team is not liable for any loss or damage of any kind — direct, indirect, incidental, special, consequential or punitive, including lost money, lost profits or lost data — arising from:

• any decision or action taken in reliance on results, guides or examples (prices and discounts, deadlines and dates, age checks, school or work tasks, and so on)
• input mistakes, rounding, significant digits or floating-point behaviour, and differences in date, time-zone or calendar rules
• interruptions, errors or delays of the service, and device, browser or network problems
• third-party services, including ads, and the content of or dealings on external sites
• your breach of these terms or of any law

You alone decide how to use any result, and you are responsible for that use. For anything important — money, contracts, health or legal matters — always verify with another method or a qualified professional.

Nothing in these terms excludes or limits liability that cannot be excluded or limited under applicable law, such as liability for intentional misconduct or gross negligence.

5. Acceptable use

Please use the site for lawful, personal or business calculation. Do not try to disrupt it, overload it with automated requests, probe it for weaknesses or copy it in bulk. We may block use that harms the site or other visitors.

6. Advertising and other sites

The site may show advertising from third parties such as Google. Ads are not endorsements, and we are not responsible for the content of advertisers or any other site that the site links to. How cookies and ad data are handled is explained in the privacy policy.

7. Content

The text, design and code of the site belong to the WhiteCalc team. You may use the results you calculate freely and quote short parts of our guides with a link back to the site. Please do not copy whole pages or republish them as your own.

8. Changes to these terms

We may update these terms when the site changes. The updated version applies from the moment it is published on this page. Continuing to use the site after a change means you accept the new terms. These terms were last updated on 2026-11-14.
