Accessibility statement

Numora aims to be usable by everyone — including people who use screen readers, keyboard-only navigation, voice control, and assistive technologies. Last reviewed April 2026.

Standard we target

We target conformance with WCAG 2.2 Level AA, the same standard required by the US Section 508 refresh, the EU EN 301 549, and the UK Public Sector Bodies Accessibility Regulations. Calculators are additionally tested against the ARIA Authoring Practices guidance for form and live-region patterns.

What works today

  • Keyboard navigation. Every calculator can be operated without a mouse. Skip-to-main-content link on every page; tab order matches visual order; focus styles are visible against both light and dark themes.
  • Screen readers. Form fields have explicit labels, results are announced via live regions as inputs change, charts include accessible summary text. Tested against VoiceOver (macOS / iOS) and NVDA (Windows).
  • Color contrast. All text and UI components meet 4.5:1 contrast (or 3:1 for large text and graphical objects) in both light and dark themes.
  • Reduced motion. Hero number animations and chart transitions respect prefers-reduced-motion.
  • Zoom and reflow. Pages reflow without horizontal scrolling up to 400% zoom on a 1280×1024 viewport.
  • Imagery. Every uploaded image carries an alt text field; decorative images are marked alt="".

Known limitations

We're aware of the following gaps and are working on them:

  • Some interactive charts (line and bar) lack a non-visual data-table fallback. We surface the same numbers in the schedule table below the chart, but the table is hidden by default for long schedules. We'll add an “always show data” preference next.
  • Calculators that include drag-and-drop image uploads in the admin panel (out of scope for public users) currently lack a keyboard-driven file picker on every browser. The standard <input type="file">fallback is always present.

How we test

  • Automated checks via axe-core on every published page during CI.
  • Manual screen-reader passes on every new calculator and admin route.
  • Quarterly third-party audit against WCAG 2.2 AA.

Reporting a barrier

If you've encountered a barrier on Numora — a button you can't reach with the keyboard, a chart with no audible alternative, low contrast text, anything — email accessibility@numora.net with the URL and a brief description. We respond within two business days and aim to ship a fix within ten.
