Terms of Service

Last updated: October 2026

Your use of calorlab.com (the "Site") is governed by the terms below. By continuing to use the Site you agree to them.

CalorLab does one thing — as a daily calorie calculator it turns your basal metabolic rate and activity level into a daily calorie target for losing, gaining or maintaining weight. It multiplies your BMR by an activity factor between 1.2 and 1.9, then applies a deficit or surplus of roughly 500 calories per day for about a pound of change per week. What follows concerns only that tool and the inputs involved in it.

Practically, all the calculation needs is your body measurements and activity level. Typical reasons people open CalorLab include checking whether a maintenance estimate is realistic, and in every case the work happens on the visitor's own device rather than ours.

What the Site is

This Site is a free, browser-based daily calorie 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.

No professional relationship

Nothing here forms a client, advisory or fiduciary relationship. The Site is a tool, and how you act on its output is a matter for you.

Limits on our liability

As far as legally permitted, our liability is excluded for indirect or consequential damages and for any decision taken on the strength of a result produced here.

Governing law

These terms are governed by the laws applicable to the operator of the Site, without regard to conflict-of-law rules.

Health-related limitations

Results concerning the body describe an average, not you, and carry no diagnostic weight. They are not medical advice, they do not diagnose or treat any condition, and they should be confirmed with a qualified professional before you rely on them.

How accurate the results are

We aim to be correct and to say how the result is produced. That is not a warranty: results may contain mistakes and the material may fall out of date. Treat any figure with a known margin as an estimate.

Acceptable use

You may use the Site for personal and professional purposes. You may not attempt to disrupt it, scrape it at a rate that degrades service for others, present it as your own, or use it for anything unlawful.

Who owns what here

Ownership of the Site's copy, layout and code lies with us or our licensors. Link freely; ask in writing before reproducing substantial parts.

Third-party content and advertising

Advertising, served by outside networks, funds the Site, and some pages reference external resources. We do not control that material and are not answerable for it, and no advert influences a result.

Changes and downtime

There is no uptime promise: tools and pages may be altered, suspended or withdrawn without notice, and the Site is offered as it stands.
