Terms of Service

The service

NumberCalculator365 provides free online calculators, converters and explanatory content. No account, payment or registration is required. We may add, change or remove calculators and features at any time.

Permitted use

You may use our calculators and content free of charge for personal, educational and commercial purposes. For example, you may:

• Use any calculator as often as you like, for yourself or on behalf of clients and students.
• Share or print the results you obtain.
• Link to any page on the site.
• Quote short passages of our content with a link back to the original page.

Prohibited use

You agree not to:

• Attempt to disrupt, overload or gain unauthorized access to the site or its infrastructure.
• Access the site through scrapers, bots or other automated means that place an unreasonable load on it.
• Copy or republish our pages, calculators or written content in bulk, or present them as your own.
• Frame the site or embed it in a way that hides its origin or removes its notices.
• Use the site for any unlawful purpose.

No professional advice

Results are estimates provided for general information. They are not financial, medical, legal, tax or engineering advice, and using the site does not create any professional relationship. Verify important figures with a qualified professional before acting on them. Our disclaimer describes the limits of each type of calculator and forms part of these terms.

Your responsibility for inputs

Each result depends on the values and options you enter. You are responsible for checking that your inputs are correct and that the calculator's method suits your situation.

Accuracy and availability

We work to keep every calculator accurate and the site available, but we do not guarantee that it will be uninterrupted, error-free or available at any particular time. We may correct errors or update formulas without notice, which can change the results for the same inputs.

No warranty

The site and all content are provided “as is” and “as available,” without warranties of any kind, whether express or implied, including warranties of accuracy, merchantability, fitness for a particular purpose and non-infringement.

Limitation of liability

To the fullest extent permitted by law, NumberCalculator365 is not liable for any direct, indirect, incidental, consequential or special loss or damage arising from use of the site, inability to use it, or reliance on its results — including financial loss, health outcomes, material shortfalls or missed deadlines. Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you.

Third-party links

The site may link to websites we do not control. We are not responsible for their content, accuracy or privacy practices, and a link does not imply endorsement.

Intellectual property

The site's design, code, calculators and written content belong to NumberCalculator365 and are protected by copyright and other laws. The mathematical formulas themselves are public knowledge; our implementation and explanations of them are not. Short quotations with a link back are welcome.

Feedback

If you send us suggestions or corrections, you agree that we may use them to improve the site without any obligation to you.

Privacy

Your use of the site is also governed by our privacy policy, which explains that calculator inputs stay in your browser.

Changes

We may update these terms at any time by posting the revised version here with a new "last updated" date. Continuing to use the site after a change means you accept the updated terms.
