How we use AI

We use modern AI tools to help with research and first drafts, the same way we use a spellchecker or a spreadsheet. They make us faster. They do not make our decisions and they do not have the final word.

• A named human reviews and signs off every published page. AI never publishes on its own.
• Our content is general information only. It is not professional, medical, dietary, training or legal advice. Health and diet content carries a not-medical-advice caveat; always speak to a GP or a suitably qualified professional before making health changes.
• Our calculators give estimates, not advice. A calorie, TDEE, BMI or race-time figure is an estimate produced by a published equation, shown alongside the equation it uses, and is not a substitute for professional guidance.
• We do not make automated decisions about you. We do not profile visitors and nothing on this site decides anything about you. We do not collect your details or run lead forms.
• We do not publish fabricated statistics. Figures are taken from primary sources such as the NHS, Sport England, the National Diet and Nutrition Survey or gov.uk, or they are left out. We do not invent numbers, reviews or testimonials.

Our use of AI is guided by UK data protection law and the ICO's guidance on AI and automated decision-making. Because we make no automated decisions about people, and a person reviews everything before it is published, we stay well inside the direction of AI regulation such as the EU AI Act.

Named authorship and editorial standards

Every page is written or reviewed by a named person and dated. The named editor of FitCalcs is Oliver Mackman, accountable for our editorial standards, sourcing and corrections. Display advertising never influences what we publish, and any sponsored material would be labelled as such with the sponsor named. The full detail is in our editorial policy, and you can see the people behind the content on our editorial team page.

Fact-checking and sources

Before a page goes live, factual claims are checked against primary sources, not other websites. In practice that means:

• Population health and body-metric context taken from the NHS Health Survey for England and Sport England Active Lives.
• Diet and nutrition figures taken from the National Diet and Nutrition Survey and NHS guidance.
• General health rules and thresholds taken from gov.uk and the NHS.
• Every calculator shows its working: the exact equation it uses (for example Mifflin-St Jeor, Riegel or Karvonen) and the source behind the number.

Corrections

If something is wrong, tell us and we will fix it. Email [email protected] with the page address and what is incorrect. We respond within two working days. Material corrections are made and noted on the page so the change is visible.

Complaints

If you are unhappy with our service, we want to hear about it. Email [email protected] or write to Best Business Loans Ltd, Cust Hall, Toppesfield, Halstead, Essex, CO9 4EB, and please include your name, how to reach you, and what went wrong.

We acknowledge every complaint within five working days and aim to give a full response within four weeks. If your complaint is about your personal data and you are not happy with our response, you can also contact the Information Commissioner's Office (ICO).

Your data

FitCalcs does not collect your personal details, has no sign-up and runs no lead forms. Our calculators run in your browser and do not send your inputs to us. We show display advertising, which sets cookies, and we use privacy-respecting analytics. What is set, why, and how to control it is set out in our privacy policy and cookie policy. We are registered with the ICO under reference ZC151816.
