Terms & Disclosures

Last updated: 10 June 2026

By accessing and using FitCalc, you agree to these Terms. If you don't agree, please don't use the site.

1. Not medical advice

Important: FitCalc provides general fitness and nutrition information and calculator estimates for educational purposes only. It is not medical advice, diagnosis, or treatment, and is not a substitute for the advice of your physician or other qualified healthcare provider. Always consult a professional before starting a diet, exercise, or supplementation program — especially if you are pregnant, nursing, have a medical condition, or take medication.

Our calculators use validated population-level formulas (such as Mifflin–St Jeor, Katch–McArdle, Epley and Karvonen). Individual results vary, and the outputs are estimates — not exact prescriptions. Never disregard professional medical advice or delay seeking it because of something you read here.

2. Affiliate disclosure

Some links on FitCalc — particularly within our supplement guides — are affiliate links. If you click one and make a purchase, we may earn a commission at no additional cost to you. As an Amazon Associate and member of other affiliate programs, we earn from qualifying purchases.

Our product rankings and recommendations are based on independent research, ingredient quality, third-party testing and value — not commission rates. Affiliate relationships never determine what we recommend or how we rank it.

3. Use of the site

You may use FitCalc for your own personal, non-commercial purposes. You agree not to misuse the site, attempt to disrupt it, scrape it at scale, or use it in any way that violates applicable law.

4. Intellectual property

The content, design, calculators and branding on FitCalc are owned by us or our licensors and are protected by intellectual-property laws. You may not copy, republish, or redistribute substantial portions without permission.

5. Third-party links

FitCalc contains links to third-party websites (retailers, sources, references). We don't control and aren't responsible for their content, products, or privacy practices. Visiting them is at your own risk and subject to their terms.

6. Limitation of liability

FitCalc is provided "as is" without warranties of any kind. To the fullest extent permitted by law, we are not liable for any loss or damage arising from your use of the site or reliance on its content or calculator outputs.

7. Changes

We may update these Terms from time to time. Continued use of the site after changes means you accept the revised Terms.
