Terms of Use

Using the site means you accept these terms

By accessing or using the public CalCalc website, you agree to these Terms of Use. If you do not agree, do not use the site.

These terms apply to the public website, including the calculator, food pages, guides, research pages, and related navigation or search features made available on the site.

What CalCalc is for

CalCalc is built to help people estimate calorie targets, review food information, and read practical guidance more clearly. The site is designed for planning and orientation, not for clinical diagnosis or emergency decision-making.

Some pages are original CalCalc editorial content. Food pages and some derived summaries are built from Open Food Facts data and normalized before publication so they are easier to read and compare.

No medical advice

Everything on CalCalc is provided for general information only. Nothing on the site is medical advice, diagnosis, treatment, or a personal recommendation. Calculator outputs are estimates. Guides are informational. Food pages are reference pages, not instructions for your body.

Before changing your diet, calorie target, or meal plan, consult a qualified professional who can consider your health, history, medications, and goals. You should also review the relevant information yourself rather than treating one page or one calculator result as a final answer.

If your situation involves a medical condition, medication, pregnancy, eating-disorder history, or any other context where nutrition decisions need professional judgment, do not use this site as the deciding authority.

How to read the numbers

The calculator uses formula-based estimation. A result can be useful without being exact. Real expenditure, adherence, and weight change can differ from a formula.

Food pages can also differ from the product in your hand. Labels change, source data can lag, and small nutrient differences are normal. If a page conflicts with the package you are actually using, trust the package first.

Acceptable use

Use the site in a lawful, reasonable way. Do not try to break it, overload it, bypass security, or use it to spread malicious code or abusive traffic.

Do not use automated access in a way that degrades the service for other people. If you need data reuse or sustained automated access, do it in a way that respects the service, the source dataset, and the legal terms attached to that data.

• Do not interfere with site security, routing, or availability.
• Do not misrepresent CalCalc content as personal medical advice.
• Do not copy or republish material in a misleading way.

Availability and changes

We may update, suspend, remove, or revise any part of the site at any time. Pages, calculations, copy, and data views can change without prior notice.

The site is provided on an as-available basis. We aim for a reliable public experience, but we do not promise uninterrupted availability, error-free pages, or perfect compatibility with every browser, device, or third-party service.

CalCalc content, source data, and third-party rights

The CalCalc brand, interface, layout, and original editorial copy belong to CalCalc unless a different source is stated. Product names, brand names, packaging imagery, and trademarks may belong to their respective owners.

Some food data on the site is based on Open Food Facts. Open Food Facts publishes its database under the ODbL. That does not automatically give you rights to reuse every original CalCalc text, design element, or third-party brand asset shown on this site.

Third-party links and services

The site may link to third-party pages, datasets, app stores, or external references. Those services have their own terms, privacy rules, and availability. We are not responsible for what they do once you leave CalCalc.

Limits of responsibility

CalCalc is not responsible for decisions made solely from a calculator output, a guide, or a product page without checking the real-world context. That includes, for example, treating an estimate as a guaranteed result or relying on outdated packaging data.

To the extent allowed by applicable law, CalCalc is not liable for indirect loss, business interruption, loss of data, or consequences that come from using or being unable to use the public website.

Changes to these terms

We may update these terms when the site changes, when the legal shape of the product changes, or when the wording needs clarification. The updated version becomes effective when it is published on this page.
