Terms of use

The rules for accessing and using VOLKAR Fit. In short: the tool is free, its results are guidelines and you decide what to do with them.

This English version is provided for your convenience. If there is any discrepancy, the Spanish version prevails.

1. Acceptance of these terms

These terms of use govern access to, browsing and use of the VOLKAR Fit website and the calorie and macronutrient calculator it offers. By accessing the site you become a user and fully accept this document in the version published at the time of access.

These terms are complemented by the legal notice and full medical disclaimer, the privacy policy and the cookie policy, which are an inseparable part of the conditions of use. If you disagree with any of them, the solution is simple: do not use the site.

2. The service

VOLKAR Fit offers the public a free tool that, based on the details users enter themselves, estimates daily calories and a macronutrient split for general fitness, and lets you download that information as a PDF generated in your browser.

The service is provided “as is”, with whatever features are available on the site at any given time. No personal advice, follow-up, individual training plan or professional support of any kind is provided.

3. Free access, no registration

Access to the site and use of the calculator are free and require no registration, subscription or account. You do not need to provide an email address to get your result or download the PDF.

The service may be funded by advertising and affiliate links, as described below. Ad blockers do not prevent you from using the tool, although, if you find it useful, allowing ads on this site is the simplest way to help keep it free.

The tool is intended for adults. If you are a minor, you need supervision from a parent or legal guardian, and in any case you should consult a health professional before making decisions about eating or training.

4. Permitted and prohibited use

You agree to use the site lawfully, in good faith and in line with these terms. In particular, you may not:

  • Use the site for unlawful or fraudulent purposes or to harm others.
  • Deliberately enter false data to obtain extreme results and share them as if they were the site’s recommendations.
  • Reproduce, copy, distribute, transform or commercially exploit the content, design or code of the site without the owner’s written permission.
  • Use automated systems for mass content extraction, or any technique that overloads the infrastructure or prevents the service from working normally.
  • Introduce or spread viruses, malicious code or anything that could damage the site’s systems or those of other users.
  • Present the calculator’s results as a diet prescription, a professional report or a document with clinical validity.
  • Remove, hide or tamper with the legal notices and health warnings that accompany the results or the PDF.

The owner may take whatever technical or legal measures it considers appropriate against uses that breach these terms, including restricting access.

5. Nature of the results and user responsibility

The results returned by the tool are automatic estimates based on population formulas, calculated from data you report yourself and that we cannot verify. Their accuracy depends directly on how truthful and precise your input is, especially your activity level, which people tend to overestimate.

You alone decide, freely and under your own responsibility, what to do with these numbers: follow them, adjust them, check them with a professional or ignore them. The owner of the site plays no part in that decision and cannot judge whether it suits your particular case.

6. Health warning

This tool provides estimates for informational and general fitness purposes. It is not medical advice, diagnosis or treatment, and you should talk to a health professional before making significant changes to your diet or exercise, especially if you have a pre-existing medical condition.

The full version of this warning, including the situations in which you should not use the calculator at all, is in the full medical disclaimer. Reading it is part of the conditions for using the service.

7. Downloadable PDF

The PDF is created entirely in your browser and saved on your device. You are granted a personal license to use that document: you can keep it, print it and share it with your coach or the health professional who looks after you.

You may not, however, alter its content to remove the legal warnings, sell it, present it as a professional report, or distribute it as your own or someone else’s material. The document deliberately includes the health warning, which must be kept intact in any use or distribution.

8. Affiliate links and advertising

When monetization is active, some links on the site, in particular those in the supplements section and in the PDF, are affiliate links: if you buy through them, the owner may earn a commission at no extra cost to you. This is disclosed clearly next to the links themselves, in line with advertising transparency requirements.

Supplement suggestions are general and informational, not a personal regimen. We do not sell or distribute those products: any purchase is made solely between you and the relevant store, under its own terms, prices, delivery times and cancellation rights. Any issue with an order must be raised with the seller.

The site may also show advertising served by third-party networks. We do not endorse or verify the content of the ads that may appear, which is the responsibility of the advertiser and the ad network.

9. Intellectual property

The website, its code, design, texts and graphics are protected by intellectual and industrial property law and belong to the owner or are used with proper authorization. Using the site does not give you any rights over them beyond what is strictly necessary for your personal use.

You may quote and link to the content as long as you name the source, do not change its meaning and do not suggest a relationship, sponsorship or endorsement that does not exist.

10. Availability of the service

The owner will try to keep the site accessible and up to date, but does not guarantee continuous availability or the absence of errors. The service may be temporarily interrupted for maintenance, technical issues at the hosting provider, updates or reasons beyond our control.

The owner may also change, suspend or remove the site or any of its features, including the calculator itself, at any time and in whole or in part, without this giving rise to any compensation, given that the service is free.

11. Limitation of liability

To the extent permitted by applicable law, the owner is not liable for damage or loss arising from:

  • Decisions about diet, training or supplements you make based on the estimates.
  • Inaccurate results caused by incorrect or unrepresentative data you entered.
  • Being unable to access the site, service interruptions or technical failures beyond its control.
  • The content, products, prices, terms or practices of linked third-party websites, including supplement stores.
  • Misuse of the PDF by you or by third parties.

No clause in these terms excludes or limits the owner’s liability where such exclusion is prohibited by law, especially toward consumers, or in cases of willful misconduct or gross negligence.

The site may contain links to pages run by third parties. They are included for informational or commercial purposes and do not mean that the owner endorses, supervises or shares their content. When you leave this site, the terms and privacy policies of the destination apply, and we recommend reading them.

If you find a broken, misleading or inappropriate link, please let us know so we can review or remove it.

13. Changes to these terms and severability

The owner may change these terms to adapt them to legal, technical or functional changes. The version that applies is the one published on this page at the time of access, with its last update date, so we recommend checking it from time to time.

If any clause of this document is declared void or unenforceable by a competent authority, the rest remains fully valid and enforceable.

14. Governing law, dispute resolution and contact

These terms are governed by Spanish law. Any dispute arising from accessing or using the site will be submitted to the courts that have jurisdiction under applicable law, always respecting the jurisdiction that legally applies to users acting as consumers.

For information, the European Commission provides consumers with an online dispute resolution platform at ec.europa.eu/consumers/odr.
