Last updated: 19 August 2026. Longevity Lab is built so that people can read it whatever device, browser or assistive technology they use. This page states where we stand, honestly, including the parts that are not finished.
Conformance target
We target Web Content Accessibility Guidelines (WCAG) 2.2, Level AA. That is the standard referenced by the European Accessibility Act and by EN 301 549 in Europe, by Section 508 in the United States, and by the courts that apply the Americans with Disabilities Act to websites. We consider the site substantially conformant: every published page passes our automated and manual checks, and we treat any failure as a defect to fix rather than a limitation to document.
What we test, on every release
- Automated auditing of every page in the sitemap with axe-core and HTML CodeSniffer, run as a release gate. A new accessibility violation blocks the deployment.
- Keyboard operation — every interactive element can be reached and used with a keyboard alone, in a visible and logical order, with a “Skip to content” link as the first stop on every page.
- Colour contrast — text and interface colours are checked against the 4.5:1 minimum. Our brand teal was darkened specifically to clear it.
- Reflow and zoom — the site is checked at a 320 pixel viewport and at 400% magnification, where content must reflow into a single column with no horizontal scrolling and no loss of information.
- Images — every image carries alternative text, verified page by page in a real browser rather than assumed from the markup.
- Structure — exactly one first-level heading per page, headings that descend in order, landmark regions, and a page language declared in the markup so screen readers pronounce it correctly.
- Motion — animation is minimal and respects the operating system’s reduce motion setting.
Known limitations
- Some articles quote tables of figures from published studies. Long tables scroll horizontally inside their own container on a narrow screen; the page itself never does.
- We have not yet completed a full audit with each major screen reader on each major platform. Our testing to date is automated plus manual keyboard and zoom checks.
- Content we link to on other sites — scientific databases, journals, health organizations — is outside our control and may not meet the same standard.
Compatibility
The site is built with standard, semantic HTML and works in current versions of Chrome, Edge, Firefox and Safari on desktop and mobile, with or without JavaScript enabled. It does not depend on any browser plugin. We do not use an accessibility overlay widget, because overlays routinely interfere with the assistive technology a reader already has configured.
Tell us about a barrier
If any part of this site is difficult or impossible for you to use, we want to know — that is the fastest way for it to get fixed. Write to info@longevity-lab.fit with “Accessibility” in the subject line, and tell us the page, what you were trying to do, and what technology you were using. We aim to acknowledge within three working days and to give you a timescale for a fix, or the information in another format in the meantime.
Enforcement
If you are not satisfied with our response, you can raise the matter with the accessibility enforcement body in your country. In the European Union that is the national market surveillance authority designated under the European Accessibility Act; in the United Kingdom it is the Equality Advisory and Support Service.
