Accessibility statement
We want every signatory and every reader to be able to use this site, including those who navigate with a keyboard, with a screen reader, or with assistive technology of any kind.
Conformance target
The site is designed to meet Web Content Accessibility Guidelines (WCAG) 2.2, level AA, as published by the W3C. We treat WCAG 2.2 AA as the bar both for new work and for fixing existing issues.
What we do
- Use semantic HTML and ARIA landmarks so screen readers can navigate the page structure.
- Provide visible keyboard focus on all interactive controls.
- Label every form field and pair every input with a visible label and helper text where useful.
- Maintain a colour-contrast ratio of at least 4.5 : 1 for body text and 3 : 1 for non-text contrast.
- Avoid third-party fonts, scripts, and embeds on pages that handle authentication or personal data, so behaviour is predictable for assistive technology.
- Use plain language wherever possible; the privacy notice and terms each include a plain-language summary at the top.
Known limitations
We currently know of no major accessibility blockers. If you encounter a barrier — a missing label, a focus trap, a contrast issue, an ARIA attribute that misbehaves with your screen reader, anything — please tell us, and we will fix it.
How to report an accessibility problem
Use the Report form and choose the
General contact category, or write to
admin@leidendeclaration.ai
with the subject line beginning [a11y]. Tell us:
- The page you were on (URL).
- What you were trying to do.
- What went wrong (an error message, a missing label, a behaviour that surprised you).
- The assistive technology you were using, if any (e.g. NVDA on Windows, VoiceOver on macOS, Orca on Linux).
We aim to acknowledge accessibility reports within 5 working days and to publish a fix or a clear timeline within 30 days. For genuinely complex issues we will keep you updated.
Compatibility
The site is tested against current versions of the major browsers (Firefox, Chrome, Safari, Edge) and works with JavaScript disabled or enabled for every page that does not strictly need it. If you find a feature that fails without JavaScript, please report it as above.
Standards we follow
This statement is informed by the format of the W3C Accessibility Statement Generator and the public-sector accessibility-statement obligations under the EU Web Accessibility Directive 2016/2102 and the Swiss Behindertengleichstellungsgesetz (BehiG) / Verordnung (BehiV). The Leiden Declaration is a non-commercial community initiative and is not itself a public-sector body, but we adopt the same statement format voluntarily.
