Accessibility

Last updated: May 15, 2026

Nummmbers is built for adults who are coming back to math. Accessibility isn’t an add-on for us. If someone can’t read, hear, or navigate the lessons, the product isn’t doing its job.

What we conform to

We aim for Web Content Accessibility Guidelines (WCAG) 2.2 Level AA. That includes things like:

  • Text and meaningful images meet AA contrast against their background.
  • Every page is fully operable by keyboard, with a visible focus ring.
  • Screen readers get meaningful descriptions of diagrams, charts, and interactive math visuals, not just “image.”
  • Motion is restrained, and animation respects the operating system’s reduce-motion preference.
  • The layout reflows at 320px width and at 200% zoom without losing content or function.

How we got here

We did a full WCAG 2.2 AA audit on the lesson player, dashboard, auth flows, and marketing pages, and shipped the cascade of fixes that came out of it. Automated checks (axe-core) run against the key pages on every change. We also do manual screen-reader passes when the visuals change in non-trivial ways. The contrast, focus, and ARIA work is ongoing, not one-and-done.

Known limitations

The honest list. We’d rather tell you than hide it.

  • The AI tutor.Tutor responses are generated in real time and aren’t pre-validated for screen-reader phrasing. They’re plain text and read cleanly in most cases, but the math notation it produces (fractions, square roots) reads literally to assistive tech.
  • Some legacy diagrams.Older lesson diagrams may have shorter descriptions than the standard we now hold ourselves to. We’re working through them.
  • Mobile screen readers.Our automated checks cover desktop Chrome and the iPhone 14 viewport in Safari. We haven’t systematically tested VoiceOver on real iOS devices or TalkBack on Android. If you use either and hit a barrier, please tell us.

If you hit a barrier

Email support@nummmbers.com and tell us what you were trying to do, what didn’t work, and the device + assistive technology you were using. We’ll get back to you and we’ll try to ship a fix, not just an apology.

The standard we hold ourselves to

Real conformance, not a badge. WCAG 2.2 AA is the floor. When a learner with a disability can complete a lesson with the same ease as anyone else, that’s the bar. We’re not there on every single page yet, and we’ll keep saying so honestly here until we are.
