Terms of Use

By accessing or using HealthCalcNow (the "site"), you agree to these Terms of Use. If you don't agree, please don't use the site. If we change these terms, we'll update the "Last updated" date above; continuing to use the site after a change means you accept it.

HealthCalcNow provides general information and estimates for educational purposes only. It is not medical advice, diagnosis, or treatment, and it does not create a doctor–patient relationship. The calculators cannot examine you or know your history. Always consult a qualified healthcare professional before making decisions about your health, and never disregard or delay professional advice because of something you read here. In an emergency, contact your local emergency services.

We build our calculators on published, cited formulas and test them against reference values, but every result is an estimate and may not fit your individual circumstances. The site is provided "as is" and "as available," without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, or uninterrupted availability. You use the site and its results at your own discretion and risk.

To the fullest extent permitted by law, HealthCalcNow and its operators will not be liable for any indirect, incidental, or consequential damages, or for any decisions made or actions taken in reliance on the site or its results. Your sole remedy if you're dissatisfied with the site is to stop using it.

• Don't use the site for any unlawful purpose or in a way that could damage, disable, or impair it.
• Don't attempt to gain unauthorized access to any part of the site or its systems.
• Don't scrape, republish, or resell the site's content in a way that misrepresents its source or violates the intellectual-property terms below.

The site's design, code, and original written content are the property of HealthCalcNow and protected by applicable laws. The underlying scientific formulas and public-health guidance are the work of their respective organizations, cited on each calculator. You may share links to the site and quote short excerpts with attribution.

The site may link to third-party resources (for example, source organizations) and uses third-party analytics as described in our Privacy Policy. We aren't responsible for the content or practices of third-party sites, and a link is not an endorsement.

We may update, add, or remove calculators and content at any time, and may revise these terms as the site grows. Questions about these terms can be directed to the contact channel listed on our About page once available.
