1. Agreement

These terms apply when you browse grenval.info. By using the site, you agree to respect these terms and all applicable laws. If you do not agree, please stop using the site. This agreement takes effect from the moment a page on grenval.info is loaded in a browser, and it applies equally to a first-time visitor and a regular reader of the newsletter. Continued use of the website after a change to these terms, as described in Section 9, is treated as acceptance of the revised wording, though a reader who disagrees with a change remains free to stop using the site at any time without penalty. These terms sit alongside the separate privacy policy and cookie policy, which govern how personal information and storage technologies are handled, and together the three documents form the complete basis on which grenval.info is made available.

  • a) These terms apply to every page, article and downloadable resource published under the grenval.info domain.
  • b) A reader who does not agree to these terms should discontinue use of the website immediately.
  • c) These terms should be read together with the privacy policy and cookie policy referenced elsewhere on the site.

2. Editorial scope

Grenval publishes general information for education and discussion. Content is not individual guidance and should not be used as the sole basis for a personal decision. This editorial scope extends to every article currently published, including the pieces covering how the male heart is generally discussed across different decades of adult life, the evidence commonly cited around omega-3 intake, resting heart rate, magnesium and heart rhythm, exercise and red meat consumption, all of which are written to inform general discussion rather than to direct any specific reader's choices. The scope also covers any future article added to the site under the same men's heart and cardiovascular wellbeing theme, as well as the newsletter, which summarises or links to the same editorial material. Nothing in this editorial scope should be read as extending Grenval's role beyond that of an independent publisher of general interest content.

3. Accuracy

The editorial team aims for careful, current writing, but no page can account for every circumstance. Dates, links and summaries may change as sources develop. Readers should check important matters with an appropriate qualified professional. For instance, an article summarising a study published in a peer-reviewed journal reflects the state of that research at the time of writing, and a later study reaching a different conclusion does not retroactively make the original article inaccurate, only potentially dated. Grenval reviews articles periodically, as described in the disclaimer, but cannot guarantee that every page reflects the most recent research available at the exact moment a reader visits the site. Where an external link referenced in an article becomes unavailable or is redirected by the third party that hosts it, Grenval will attempt to update the reference within a reasonable period but is not responsible for the availability of content it does not control.

4. Intellectual property

Text, layout and branding belong to Grenval Health Ltd or their credited owners. You may link to an article and quote a short excerpt with attribution. Reproducing a complete article or presenting it as your own is not permitted without written consent. A short excerpt for these purposes is generally understood to mean a small proportion of the original text, sufficient to illustrate a point in the context of fair dealing under the Copyright, Designs and Patents Act 1988, accompanied by a clear attribution to Grenval and, where practicable, a link back to the original article. Copying an entire article to another website, republishing it in a newsletter without permission, or presenting Grenval's original wording as though it were written by someone else all fall outside the permitted use described in this section. A request to reproduce a larger portion of an article for a legitimate editorial, educational or research purpose can be sent to [email protected] and will be considered on its individual merits.

  • a) Permitted: a hyperlink to an article together with a short, attributed quotation.
  • b) Not permitted without written consent: full reproduction of an article on another website or publication.
  • c) Not permitted under any circumstance: presenting Grenval's original text as the reader's own work.

5. Acceptable use

Do not interfere with the site, attempt unauthorised access, scrape personal information or submit unlawful material. Grenval may restrict access where misuse threatens readers, staff or the service. Interfering with the site includes, for example, attempting to overload the server with automated requests, attempting to bypass the consent banner through technical means, or submitting a contact form repeatedly with the intention of disrupting the service for other readers. Scraping personal information covers any attempt to extract email addresses, contact details or other personal data from the website's pages or forms for a purpose other than the reader's own individual enquiry. Where Grenval identifies conduct that falls within this section, it may restrict or block access from the relevant device or network, and in a serious case involving unlawful activity, it may report the matter to the relevant authority, such as Action Fraud or the police.

6. External links

Links to external resources are provided for context. Grenval does not control those sites and is not responsible for their availability, content or privacy practices. An external link may appear, for example, where an article references a published study, an NHS information page or a government resource, and following such a link takes the reader away from grenval.info to a website governed by its own terms and privacy practices. Grenval reviews external links at the point an article is published or revised but cannot guarantee that a linked page will remain accurate, available or unchanged indefinitely after that point. A reader who encounters a broken or misleading external link is encouraged to report it to [email protected] so the reference can be reviewed and, where appropriate, updated or removed.

7. Liability

To the fullest extent permitted by UK law, Grenval is not responsible for loss arising from reliance on general editorial material. Nothing in these terms limits liability that cannot lawfully be limited. This limitation is intended to reflect the informational, non-individualised nature of the content described throughout these terms and the disclaimer, and it applies to both direct and indirect loss that might arise from a decision made on the basis of a general article. It does not, however, exclude or limit liability for death or personal injury caused by Grenval's negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be excluded under the Consumer Rights Act 2015 or other applicable UK legislation. Where a reader believes a specific loss has resulted directly from an error in Grenval's own published material, rather than from an unsupervised personal decision, that concern can be raised using the contact details in Section 8 for individual review.

8. Contact

Questions about these terms can be sent to [email protected] or Grenval Health Ltd, 51 George Street, Edinburgh EH2 2AF. Grenval aims to acknowledge a query about these terms within five working days and to provide a substantive reply within one month, consistent with the response times described in the separate privacy policy. Where a query relates to a request to reproduce content under Section 4, or to a concern about acceptable use under Section 5, the reply will address that specific request directly rather than repeating the general text of these terms. A reader who is not satisfied with Grenval's response to a query about these terms remains free to seek independent legal advice, since nothing in these terms is intended to prevent a reader from exercising a right available to them under UK law.

9. Changes

These terms were last updated on 24 September 2026. A revised version takes effect when published. Continued browsing after an update indicates acceptance of the revised wording. A material change to these terms, such as a change affecting acceptable use, liability or intellectual property permissions, will be reflected by an updated date at the top of this section and, where practicable, a visible notice on the homepage for a reasonable period following publication. A reader who wishes to review the terms that applied on an earlier visit can request a copy of a previous version by contacting [email protected], subject to availability. Grenval recommends that a regular visitor check this page periodically, particularly before relying on the intellectual property permissions described in Section 4.

  • a) 24 September 2026 — current version published, aligned with the disclaimer and privacy policy referenced throughout these terms.
  • b) A future revision affecting Sections 4, 5 or 7 will be accompanied by a homepage notice for a reasonable period after publication, in addition to the updated date shown here.
  • c) Minor corrections that do not change a reader's rights or obligations under these terms, such as a typographical fix, may be made without a separate homepage notice.
