Accessibility statement

1. What we claim

Didache aims to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA.

We consider the product partially conformant with WCAG 2.2 level AA. Partially conformant means most of the product meets the standard, and that the parts which do not are named in section 5 rather than left for you to discover.

2. What this covers

This statement covers the public pages and the signed-in application: the learner dashboard, tracks, lessons, challenges, the prompt library, practice, the manager area and the platform administration area.

It covers both languages of the interface, English and Greek, and both the light and the dark appearance.

It does not cover content that customer organizations write themselves — lesson text, images and prompts authored inside the product — nor material published on services we do not control.

3. How we checked

This is a self-assessment carried out by the team that builds the product. No external audit has been carried out and no certification has been obtained.

Colour contrast is measured rather than judged. Every combination of text and background, every control boundary and every meaningful graphic in the design system is measured against the WCAG formula and checked automatically whenever the product is built; a combination that falls below its threshold stops the build.

The remaining checks — keyboard operation, accessible names, headings and the structure assistive technology reads — are covered by automated tests that run on every change, and by manual review using a keyboard alone.

The assessment was made on 2 September 2026, against the version of the product in production on that date.

4. What we have done

Every colour used for text meets a contrast ratio of at least 4.5 to 1 against every surface it is drawn on. Control boundaries, focus indicators and graphics that carry meaning meet at least 3 to 1.

Every control can be reached and operated with a keyboard alone and shows a visible focus indicator. Content that can be reordered by dragging can also be reordered from the keyboard.

No information is conveyed by colour or shape alone. A locked milestone, for example, says in words when it opens.

Every name that assistive technology reads is translated, so the Greek interface is Greek to a screen reader and not only on screen.

The accent colour is fixed and measured. It is no longer set per organization, because a colour supplied while the page is running cannot be measured in advance.

5. What still falls short

Content written by customer organizations. Lesson text, images and prompts are authored inside the product by our customers. We cannot guarantee that an image an author uploads carries a useful text alternative, or that their headings are ordered correctly.

Embedded video. Videos hosted on YouTube and Vimeo play in those services' own players, which we do not control. Captions depend on what the video's publisher provided.

Diagrams. Diagrams in lessons are drawn as images from text. The text they are built from is not currently offered to assistive technology, so a reader who cannot see the diagram gets only the surrounding explanation.

Feedback written by ADA. Text generated when a submission is evaluated has not been reviewed for reading level or plain language.

No external audit. Everything above is our own assessment. It has not been checked by anyone outside the team, and it has not been tested across a broad range of assistive technologies or by disabled people.

6. Tell us

If you meet a barrier in Didache, or you disagree with anything in this statement, write to info@didache.ai. Please tell us the page, what you were trying to do, and what happened.

We aim to reply within five working days, and to say what we intend to do about it and by when.

If you use assistive technology, telling us which one and which version helps us reproduce what you saw.
