Welcome to TrueFit BMI (accessible at https://www.truefitbmi.com). By accessing or using our website, interactive body composition calculator, and educational resources, you agree to be bound by these Terms of Service ("Terms") and our Privacy Policy. If you do not agree to these Terms, please refrain from using the site.

Important Medical & Clinical Health Disclaimer

TrueFit BMI is provided exclusively for general educational, fitness tracking, and informational purposes. The calculations, metrics, visual spectrums, and category assessments (including BMI, Waist-to-Height Ratio, and estimated healthy weight ranges) do not constitute medical advice, diagnosis, treatment, or clinical screening. The calculator and its BMI categories are designed for adults aged 20 and older and are not intended for children, teens, or people who are pregnant. Always seek the advice of a qualified healthcare provider before starting any significant weight loss, dietary, or intense physical training program.

1. Acceptance of Terms

By browsing, calculating measurements on, or interacting with TrueFitBMI.com, you certify that you are at least 13 years of age and hold the legal capacity to enter into these Terms. We reserve the right to revise or modify these Terms at any time without prior individual notice. Your continued use of the website following any posted modifications signifies your formal acceptance of the revised Terms.

2. Permitted Use & Intellectual Property

All software algorithms, user interface designs, custom CSS layouts, graphic spectrum visualizers, logos, and editorial articles published on TrueFit BMI are the intellectual property of TrueFit BMI and are protected by applicable copyright, trademark, and intellectual property laws.

You are granted a personal, revocable, non-exclusive, non-transferable license to use our web calculator for individual, non-commercial fitness assessment. You agree not to:

3. Department of Defense & Military Standards Notice

Government & Armed Services Disclaimers:

References to the United States Department of Defense (DoD), the U.S. Army Body Composition Program (including Army Directive 2026-13 and its waist-to-height ratio standard), or other military branches are provided strictly for educational comparison and benchmarking. TrueFit BMI is an independent health resource and is not affiliated with, endorsed by, or operating on behalf of the Department of Defense or any branch of the U.S. Armed Forces.

Our tools are designed to help users understand how waist-to-height ratio adds context to BMI, including for muscular individuals, and how their own measurements compare with the Army's published standard. Military standards can change, and this calculator cannot replace an official military body composition assessment performed by authorized personnel.

4. Advertising, Affiliate Links & Third-Party Content

TrueFit BMI may participate in digital advertising networks, including Google AdSense, and may include clearly labeled affiliate links, to fund the site and keep our tools free. When interacting with ads or affiliate links on the site, you acknowledge that:

5. Client-Side Processing & Data Security

We prioritize your privacy and data security. All numerical biometric data entered into our input fields—including height, weight, and waist measurements—are processed entirely on your local device via client-side JavaScript. TrueFit BMI does not transmit, store, or harvest your biometric metrics on any remote database or web server.

6. Disclaimer of Warranties

TrueFit BMI is provided on an "AS IS" and "AS AVAILABLE" basis without warranties of any kind, whether express, implied, statutory, or otherwise. To the fullest extent permissible under applicable law, TrueFit BMI expressly disclaims:

7. Limitation of Liability

In no event shall TrueFit BMI, its developers, operators, or affiliates be liable for any indirect, incidental, special, consequential, or punitive damages—including but not limited to personal injury, physical ailment, emotional distress, loss of fitness data, or loss of profits—arising out of or in connection with your access to, reliance on, or inability to use this website and its calculators.

8. External Links & Informational References

Our website may provide hyperlinks to external medical journals, health authorities (such as the CDC and WHO), and fitness publications. These external links are provided solely as a convenience. We maintain no editorial control over third-party websites and assume no responsibility for the accuracy or integrity of their information.

9. Governing Law & Jurisdiction

These Terms shall be governed by and construed in accordance with the laws of the United States and the State where the operator resides, without giving effect to any principles of conflicts of law. Any legal proceeding arising out of these Terms shall be resolved exclusively in the state or federal courts having jurisdiction over that territory.

10. Severability & Entire Agreement

If any provision of these Terms is deemed unlawful, void, or unenforceable for any reason, that provision shall be deemed severable and shall not affect the validity and enforceability of any remaining provisions. These Terms constitute the entire agreement between you and TrueFit BMI regarding your use of the website.
