Terms of Service

Last updated: October 2026

The following terms apply to bmrscope.com (the "Site"). Acceptance is implied by use, so if they are not acceptable to you, please stop using the Site.

BMRScope is a basal metabolic rate calculator: it estimates the calories your body burns at complete rest using the Mifflin-St Jeor, Harris-Benedict and Katch-McArdle formulas so you can compare the three. In practice, Mifflin-St Jeor weights weight, height, age and sex into a single linear equation, while Katch-McArdle works from lean body mass instead — showing all three makes the disagreement between models visible rather than hiding it. This page should be read with that tool in mind, because the limits described apply to what it computes.

Everything the tool works with — your weight, height, age, sex and body-fat percentage — is handled locally. It is usually reached for things like understanding why two BMR calculators disagree, and because nothing is transmitted a visitor can close the tab knowing no copy was made anywhere.

The service we provide

This Site is a free, browser-based basal metabolic rate calculator. Its output is produced from your input using the stated method and is provided for information and education, not as advice. Anything relating to the body is an estimate drawn from population data, not a personal measurement, and it is not medical advice and does not diagnose or treat any condition.

Not professional advice

Nothing on the Site creates a professional relationship of any kind. You are responsible for how you use any result.

Third-party content and advertising

Third-party adverts keep the Site free and external links appear for convenience. We vouch for neither, and neither can change an output.

Uptime and changes to the service

There is no promise of continuous availability: any tool or page may be altered or removed, and the service is supplied in its current state.

What we are not liable for

As far as the law permits, we exclude liability for indirect or consequential loss and for any decision taken in reliance on a result from the Site.

The law that governs these terms

These terms are subject to the laws of the Site operator's jurisdiction, and conflict-of-law provisions do not override that.

Health-related limitations

Results relating to the body are population estimates, not measurements of you, and are not medical advice. They do not diagnose, treat, cure or prevent any condition. Consult a qualified healthcare professional before changing your diet, training or medication.

Accuracy of results

Correctness is a goal, not a warranty: results may contain errors and the content may lag changes in the field. Where the underlying method has a margin of error, read the output accordingly.

What you may and may not do

Use the Site freely for yourself or your work. What is not allowed: disrupting the service, scraping it hard enough to hurt performance for others, claiming it as your own, or any unlawful purpose.

Intellectual property

Unless credited otherwise, the Site's design, writing and code are ours or used under license. Linking to any page is welcome; copying large portions of the content needs our written consent.
