Terms of Service

Last updated: October 2026.

By using protein-calculator.com, you agree to these terms. If you do not agree, please do not use the site. We may update these terms from time to time, and continued use of the site after changes means you accept the updated terms.

What this site is

Protein Calculator provides free online calculators and educational articles about protein intake and nutrition. All tools and content are provided for general information only.

Not professional advice

Our calculators produce estimates based on widely published nutrition formulas. They are not medical advice, dietetic advice, or a substitute for guidance from a qualified health professional. Protein needs vary with health conditions, medications, pregnancy, age, and many other factors. Always consult your doctor or a registered dietitian before making significant changes to your diet, especially if you have a health condition.

Accuracy

We work hard to keep our formulas, figures, and articles accurate and up to date, and we check them against reputable sources. But nutrition science evolves, and errors can happen. We do not guarantee that any result or article is complete, current, or free of mistakes. You use the site’s tools and content at your own judgment.

Acceptable use

You agree to use the site lawfully and reasonably. You must not attempt to disrupt the site, scrape it aggressively in a way that degrades service for others, or use it for any unlawful purpose. We may restrict access for anyone who abuses the site.

Intellectual property

The calculators, articles, design, and other content on this site are our property or used with permission. You are welcome to link to our pages and to quote brief excerpts with credit. Republishing full articles or copying our calculator tools to another site without permission is not allowed.

External links

We link to outside sources, such as research publishers and nutrition references, to support our content. We do not control those sites and are not responsible for their content, accuracy, or privacy practices.

Advertising

The site displays third-party advertisements to keep our tools free. We do not endorse advertised products, and any dealings you have with advertisers are between you and them.

Limitation of liability

To the fullest extent permitted by law, we are not liable for any loss or damage arising from your use of the site, including decisions you make based on calculator results or articles. Our total liability, if any is found, is limited to the amount you paid to use the site, which is nothing.

Changes to the site

We may change, suspend, or discontinue any part of the site at any time without notice, for example to fix errors, update content, or perform maintenance.

Governing law

These terms are governed by the laws of the jurisdiction where the site operator is based, without regard to conflict-of-law rules. Any dispute will be handled in the courts of that jurisdiction.
