Accessibility statement for the app

Last updated: September 2026

khema (Gabriel Zerbe) is committed to making the Khema app accessible in accordance with the German Disability Equality Act (BGG) and the Barrier-Free Information Technology Ordinance (BITV 2.0), which implement Directive (EU) 2016/2102.

This statement applies to the Khema app for iOS (iPhone and iPad) and Android. Our website has its own statement at khema.ai/en/accessibility.

Compliance status

The applicable standard is EN 301 549 with the WCAG 2.1 level AA success criteria. We build the app to WCAG 2.2 level AA. Because of the deviations below, the app is partially compliant with these requirements.

Non-accessible content

  1. Screen orientation (WCAG 1.3.4). On phones the app stays in portrait. Settings → Accessibility → “Allow rotation” lets it turn with the device. You can reach these settings before sign-in too, through “Accessibility” on the welcome screen. On tablets the app always turns with the device.
  2. Contrast in the standard presentation (WCAG 1.4.3, 1.4.11). Some text, icons and edges have too little contrast. The contrast levels “Increased” and “High” under Settings → Accessibility → Contrast meet every contrast requirement. “Increased” turns on automatically when “Increase Contrast” (iOS) or “High contrast text” (Android) is on.
  3. Two games in the emergency kit (WCAG 2.1.1, 2.5.1). “Smoke Ninja” and “Cloud Hopper” are controlled by swiping or tilting the device and cannot be played with a screen reader. Their input depends on the path of the movement, which is a permitted exception. The other games and all exercises in the emergency kit work with a screen reader.
  4. Time limit in the chat (WCAG 2.2.1). A conversation ends after about 90 minutes without a new message. The app warns beforehand while the chat is open. The time can only be extended by sending a message. After the end the conversation stays readable, an unsent text is kept, and you can start a new conversation right away.
  5. Sign-in pages in the browser (WCAG 1.4.1, 1.4.3, 1.4.11). Sign-in, registration and account management run on auth.khema.ai in the browser. In the standard presentation some text and edges there have too little contrast, and links in running text are marked only by colour and font weight. The levels “Increased” and “High” in the “Accessibility” menu of these pages meet these requirements.
  6. Privacy policy (WCAG 2.4.4). Some links are named only by their web address.

Preparation of this statement

This statement was prepared on 28 September 2026 and last reviewed on 30 September 2026. It is based on a self-assessment: a review of the source code against WCAG 2.2 level AA and automated tests. Testing with assistive technology on devices is still pending, and no third-party assessment has taken place.
