Accessibility Statement
Calcxo is built so anyone can calculate, regardless of device, ability, or assistive technology. This page explains the standards we follow, what we test, and how to reach us if something gets in your way.

Our standard
We design and test against WCAG 2.2 Level AA. That covers keyboard operation, color contrast, screen reader semantics, focus visibility, motion preferences, and form accessibility.
What we actively test
- Full keyboard operation — every calculator, control, and link works without a mouse.
- Visible focus rings on all interactive elements.
- Semantic HTML (headings, landmarks, labelled form controls) for screen readers including VoiceOver, NVDA, and TalkBack.
- Color contrast of at least 4.5:1 for body text and 3:1 for large text and UI components.
- Respect for
prefers-reduced-motion— non-essential animation is suppressed when requested. - Layouts that reflow cleanly down to 320px wide without loss of content or function.
Known limitations
A few advanced charts and complex tables are still being annotated for screen readers. Where this is the case, the same data is also available in plain text near the visual. If you hit a barrier we have not listed, we want to hear about it.
Need help or want to report a barrier?
Email accessibility@calcxo.com with the page URL, the assistive technology you were using, and a short description of what went wrong. We aim to respond within two business days and will offer the information in an alternative format if needed.
