Accessibility Statement

CleverCalculator is built to be useful to everyone, including people who rely on assistive technology.

Effective: June 1, 2026

Our commitment

CleverCalculator aims to conform to WCAG 2.2 Level AA, the technical standard most commonly applied by US courts under Title III of the Americans with Disabilities Act. Accessibility is a baseline, not an add-on — every new calculator and every layout change is reviewed against this standard before it ships.

Measures we take

  • Semantic HTML throughout, with landmark elements (<header>, <main>, <footer>) so screen readers can navigate the page structure.
  • Labels associated with every form input. Radio groups use fieldset/legend or role="radiogroup".
  • Visible keyboard focus on every interactive element. The Site is fully usable with the keyboard alone.
  • Text is left in the visitor’s preferred size; the layout reflows down to 320 pixels wide without horizontal scrolling.
  • Color contrast targets 4.5:1 for body text and 3:1 for large text and interactive controls.
  • No content depends on color alone — category accents are paired with text labels and icons.
  • Calculator results update an ARIA live region so assistive technology announces them.
  • Math formulas use KaTeX, which produces accessible MathML in addition to the rendered visual output.
  • Captions and transcripts are provided where we add a video (none yet).

Known limitations

We are aware of these areas where we are still working toward full conformance:

  • A handful of older custom calculator widgets pre-date our accessibility checklist and may have minor labeling gaps. They are being audited one by one.
  • Some long reference tables would benefit from a row/column header switch on small screens.
  • The animated ticker on the homepage runs in a single direction. Users who prefer reduced motion (prefers-reduced-motion: reduce) see a static version.

Compatibility

The Site is designed to be compatible with current versions of major browsers (Chrome, Firefox, Safari, Edge) and the screen readers that pair with them (NVDA + Firefox, JAWS + Chrome, VoiceOver + Safari).

Reporting a barrier

If you find a barrier, please tell us. Email accessibility@clevercalculator.com with the page URL, a short description of the problem, and the assistive technology you were using. We aim to acknowledge within five business days and fix issues that block use as soon as possible.

Formal complaints

If you have raised an accessibility issue with us and are not satisfied with our response, you may contact the US Department of Justice’s ADA Information Line at 1-800-514-0301 or 1-833-610-1264 (TTY), or file a complaint through ADA.gov.
