1. Our goal
We aim for this website to meet the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA. This is a goal we work toward, not a certification, and we have not yet obtained an independent audit.
2. What we do
- A “skip to main content” link at the top of every page.
- A consistent layout and navigation on all pages, with a site search and a site map.
- Headings, lists and tables built with standard HTML so that screen readers can announce them.
- Form fields with visible labels, required fields marked, and clear error messages.
- Full keyboard operation and visible focus indicators.
- High-contrast text and colors that do not carry meaning alone.
- Layouts that adapt to small screens and to text enlarged up to 200%.
- No automatically playing audio, video or moving content.
3. Known limitations
The payment step is hosted by a third-party provider, and we do not control its accessibility. Third-party documents we link to, such as published research papers, may not be fully accessible. We review pages when we make changes, but some issues may remain.
4. Ask for help or report a problem
If you have difficulty using any part of this website, please contact us. Tell us the page address, what you were trying to do and the assistive technology you use. We will try to help you complete your order in another way and will use your feedback to improve the website.
