Accessibility statement

We want B1nary to be usable by everyone studying for a certification, including people who use screen readers, navigate by keyboard, or need larger text. This page says plainly what is supported today and what has not yet been verified.
Conformance target
We are working towards WCAG 2.2 Level AA. This website is built to meet it. The application itself is partially conformant: it has not yet been through a full independent audit, so we do not claim conformance for it.
What this website supports
- A skip link to jump straight to the main content.
- A logical heading structure with no skipped levels.
- Visible focus indicators on every interactive element.
- Full keyboard operability — no interaction requires a mouse or a hover.
- Text contrast of at least 4.5:1, verified in both light and dark themes rather than assumed.
- Light and dark themes that follow your system setting.
- Text that reflows without horizontal scrolling down to a 320 px viewport, and that scales when you zoom to 200%.
- Touch targets of at least 44 × 44 px.
- Respect for
prefers-reduced-motion— animation is switched off, not merely shortened. - Content that is fully readable with JavaScript disabled.
What the app supports
- Light and dark themes.
- System text-size settings.
- Screen reader labels on its main controls.
Known limitations
We would rather name these than let you discover them:
- The app has not had a full screen-reader audit, so some controls may be announced less clearly than they should be.
- The app's layout is designed mobile-first; on a tablet in landscape some screens are wider than ideal for comfortable reading.
- Some course content uses tables and diagrams whose alternatives are still being improved.
Report a barrier
If any part of this site or the app is difficult or impossible to use, please email support@binaryapp.org. Tell us the page or screen, what you were trying to do, and the assistive technology you were using if relevant.
We aim to respond within 1–2 business days and will tell you what we can fix and when.
How this was assessed
This website was assessed by internal review against the WCAG 2.2 Level AA success criteria, including contrast calculation for every text and background pair in both themes, keyboard-only navigation, and testing at 320 px, 768 px, 1024 px and 1440 px viewport widths. It has not been assessed by an external auditor.
