A question about how the site works, an error to report in a guide, or a request about your personal data? Use the form below, or write to us directly at contact@bmicorner.com. If possible, mention what your message is about in the first few words — that helps us point you to the right answer, or to the right page if the information already exists on the site.

This site does not answer personal medical questions. Neither the form nor the address above replaces a consultation: for any question about your health, your weight, or your body composition, please contact a qualified healthcare professional, who alone can assess your individual situation. In a medical emergency, contact your local emergency services immediately rather than waiting for a reply through this form or by email, which is neither monitored continuously nor suited to an urgent situation.

We can, however, answer questions about the content of our guides (including reporting an outdated source or a factual error), about how the site works technically, or handle a request related to the processing of your personal data: access, rectification, erasure, portability, objection, or withdrawing a consent you already gave. As the site has no commercial activity or partnerships at this stage, that kind of request may not be processed immediately.

BMI Corner is a small independent site: there is no phone line or dedicated support team, only an email address checked regularly. Please mention, where possible, which page your message concerns (its full address) so we can find the context of your request quickly.

This form is not yet connected to any sending service: it does not transmit any data. Until it is switched on, the email address above remains the most reliable way to reach us. We aim to reply within a reasonable time frame, without a guaranteed deadline.
