These Terms of Use ("Terms") govern your access to and use of Physique Calculator (the "Website"). By using the Website, you agree to these Terms. If you don't agree, please don't use the Website.
Physique Calculator is a free, informational tool that estimates body-composition metrics (such as body fat percentage, FFMI, and calorie needs) from measurements you provide, using published, cited formulas. It is provided for general educational and informational purposes only.
The Website does not provide medical, health, or professional advice. See our full Disclaimer for details. Always consult a qualified professional before making decisions about your health, nutrition, or training based on anything calculated here.
You agree not to:
The Website's original content — including its text, exercise descriptions, design, and the specific wording of its methodology explanations — is owned by Physique Calculator unless otherwise noted. The underlying scientific formulas we implement (such as FFMI or the Katch-McArdle equation) are not our intellectual property; they are cited to their original published sources on our Methodology page and are standard, publicly documented equations. Third-party fonts, icon libraries, and frameworks loaded by this site remain the property of their respective owners and are used under their published licenses.
The Website and its calculations are provided "as is" and "as available," without warranties of any kind, express or implied, including but not limited to accuracy, reliability, or fitness for a particular purpose. Body-composition estimates depend heavily on the accuracy of the measurements you enter — see the accuracy notes on the Calculator and Methodology pages.
To the fullest extent permitted by law, Physique Calculator and its maintainer(s) are not liable for any indirect, incidental, or consequential damages arising from your use of, or inability to use, the Website, including any decisions made based on calculator results.
The Website links to third-party services (for example, YouTube video guides in the Exercise Library, and social media). We don't control those services and aren't responsible for their content, availability, or practices. Your use of them is subject to their own terms.
We may update the Website's content or these Terms at any time. Continued use of the Website after changes are posted means you accept the revised Terms. The "Last updated" date above reflects the most recent revision.
These Terms are governed by applicable local law based on where the Website operator is established, without regard to conflict-of-law principles. (Update this section with your specific jurisdiction once the business/legal entity behind the domain is finalized.)
Questions about these Terms can be sent via the details on our Contact page.
