Accessibility statement

How conformant this site is

YFull.ai is partially conformant with the Web Content Accessibility Guidelines (WCAG) 2.1 level AA, under the European harmonised standard EN 301 549 v3.2.1. "Partially conformant" means the site does not yet meet every requirement of the standard. Conformance is judged page by page, and a page that misses a single requirement does not meet the level as a whole. The parts that do not yet meet the standard are described below.

What already works

• Clear page structure — every content page has one main heading and a logical heading order, so you can navigate by headings.
• Text descriptions — images that carry meaning have text alternatives; purely decorative graphics are hidden from screen readers so they don't add noise.
• Readable text — body text meets or exceeds the AA contrast requirement (our main text reaches AAA).
• Keyboard use — you can reach the main content with a "Skip to main content" link, and the keyboard focus is always visible.
• Screen readers — the site uses standard page landmarks, labelled form fields, and ARIA descriptions so assistive technology can announce the interface.
• Zoom and reflow — you can zoom to 200% (and beyond) without losing content or needing to scroll sideways; the layout adapts to your screen.
• Languages — the site is available in English and Spanish, and nearly every page declares its language so screen readers pronounce it correctly.

What is not fully accessible yet

• Some borders are faint. The outline of certain cards and dividers has lower contrast than the 3:1 we aim for. The text and labels inside them are fully readable.
• Not yet tested with a screen reader. Our review so far is based on the site's code and structure, not on hands-on testing with NVDA, JAWS, or VoiceOver. We plan to add that testing.
• The interactive haplogroup trees. The Y-DNA and mtDNA trees may not be fully usable with a screen reader or keyboard. On the Y-DNA tree you can switch to text-based views (Scientific, Chart and Samples) from the view switcher on the page; so far these are built only for a few branches, and on the rest the switcher marks those views "Coming soon". The mtDNA tree does not offer these alternative views yet.
• Some Tree error pages do not identify their language. Assistive technology may therefore not read them correctly.
• Very large text. If you set your browser's own text size to around 200%, many pages across the site can still require sideways scrolling, most noticeably on a narrow phone screen. We have measured this across the site and are working on it.
• Controls at the top of the page. When you set your browser's text size to around 200%, a link positioned off-screen can overlap controls at the top of the page, so they may not respond when you tap or click them. We are working on this.
• Site under active development. Some pages and links are still being built and are marked accordingly.

We do not claim any "disproportionate burden" exemption; the items above are work in progress, not omissions we consider final.

How we assessed this site

This statement is based on an internal self-assessment, most recently carried out on 2 June 2026. We assess the site in two ways: a manual review of its source code and markup, and automated accessibility testing with axe-core. This is a WCAG 2.1 level A and AA scan we run across the site's pages before we publish changes, to catch critical or serious issues. The scan does not run every check in its WCAG 2.1 level A and AA rule set. We have since checked the rules it leaves out, and this site does not currently fail any of those rules. Our assessment does not yet include hands-on testing with assistive technology such as screen readers (see "What is not fully accessible yet" above).

Dates

This statement was first prepared on 29 May 2026 and was last reviewed on 11 September 2026. We review it at least once a year, and whenever the site changes significantly.
