Product Accessibility Statement

Statement of Commitment

Posit PBC is committed to ensuring its products are accessible to people with disabilities.

Reference Standards

We seek to ensure all our web and desktop products conform to Level AA success criteria of W3C WAI WCAG 2.1. We also aim to ensure that our authoring tools conform to Level AA criteria of ATAG.

Current Status

We are training our engineers in accessibility principles, auditing our products, and establishing priorities to unblock critical scenarios. The goal is to gradually improve the accessibility of our existing features and design, build, and deliver accessible features in the future.

Assistive Technology

For screen readers and browsers, we focus our testing efforts primarily on the following combinations (based on current desktop screen reader/browser usage stats):

  • Microsoft Windows: JAWS / Google Chrome
  • macOS: VoiceOver / Safari

We do spot-checks, time permitting, on other combinations, including:

  • Microsoft Windows:
    • NVDA / Google Chrome
    • NVDA / Firefox
    • Narrator / Edge
  • iPadOS (Safari / VoiceOver)

We test using built-in operating system features for screen magnification, high-contrast settings, and voice control.

Product VPAT Documents

These documents describe how our products address WCAG 2.1 AA (which also complies with Section 508 of the US Rehabilitation Act and EN 301 549 of the European Union).
