Accessibility Statement

Lambdio aims to make its platform usable by everyone, including people with disabilities, and to meet the Web Content Accessibility Guidelines (WCAG) 2.2 Level AA. This statement describes the accessibility of the Lambdio web application (lambdio.com) and the Lambdio apps for iOS and Android.

Last reviewed: October 16, 2026

1. Conformance status

Lambdio is partially conformant with WCAG 2.2 Level AA. “Partially conformant” means that some parts of the content do not yet fully conform to the standard; the known gaps are listed in Section 5. This is a self-assessment based on automated testing and manual review, and a formal third-party audit has not yet been performed.

2. Scope

This statement covers the Lambdio web application and the Lambdio apps for iOS and Android. The apps render the same interface as the web application, so accessibility improvements apply to all three platforms; a small number of items are specific to the native apps and are noted as limitations.

3. Supported accessibility features

• Keyboard navigation. Every interactive control can be reached and operated with a keyboard, with a visible focus indicator.
• Screen-reader support. Controls are named, form fields are labelled, focus is managed inside dialogs, and new chat messages are announced. A full on-device VoiceOver/TalkBack audit is planned.
• Dark interface. A dark theme is available, and the platform also follows the device’s system theme automatically.
• Reduced motion. When your device requests reduced motion, animations and transitions are effectively disabled.
• Resizable text. Text uses relative units and scales with your operating system or browser text-size settings.
• Colour-independent status. Status is conveyed with text and symbols in addition to colour, so it does not rely on colour alone. On graded chapter quizzes, correctness is intentionally not revealed until the quiz is submitted (exam-style).
• Contrast. Text colours meet the WCAG AA contrast ratio. Verification of non-text contrast (icons, borders, and chart strokes) is in progress.

4. Compatible assistive technologies

Lambdio is designed to work with screen readers (VoiceOver on iOS/iPadOS/macOS, TalkBack on Android, NVDA or JAWS on Windows, Orca on Linux), keyboard-only navigation, operating-system text scaling and browser zoom, and the system dark-mode and reduced-motion settings.

5. Known limitations

• A full screen-reader (VoiceOver/TalkBack) audit on iOS and Android devices has not yet been completed.
• Some structural areas of the learning-session and quiz screens still use generic containers rather than semantic regions.
• Non-text contrast (icons, borders, and chart strokes) is still being verified in both themes.
• The native iOS launch screen and the Android theme have minor dark-mode inconsistencies that will be addressed in a future app update.
• A minimum touch-target size audit (WCAG 2.5.8) is pending.

6. Standards and frameworks

We aim to conform to WCAG 2.2 Level AA. We also reference EN 301 549 (EU) and Section 508 of the Rehabilitation Act (US). A VPAT/ACR and HECVAT responses are available on request.

7. How we assess accessibility

We combine automated testing (axe-core, run automatically in our build pipeline, and Lighthouse), manual keyboard and zoom testing, and planned on-device screen-reader testing. We re-check accessibility after each release.

8. Feedback and contact

We welcome reports of accessibility barriers. Please contact us and we will respond within five (5) business days. If you need information in another format, or need an accommodation, contact us and we will work with you.

9. Review date

This statement was last reviewed on October 16, 2026 and is reviewed with each release and at least quarterly.
