Accessibility

Accessibility is a right, not a feature.

Approximately 25% of U.S. adults live with a disability. Oracle is built for all of them. Accessibility is not an afterthought or a compliance checkbox — it is a foundational architectural requirement.

Our commitment.

Oracle by Lonia AI is designed and built to conform to the Web Content Accessibility Guidelines (WCAG) 2.2 Level AA and Section 508 of the Rehabilitation Act. These standards are implemented from the foundation of every page and component — not retrofitted after the fact.

Specific standards we follow.

We do not reference vague commitments to "accessibility best practices." We name the specific standards we follow and hold ourselves accountable to them.

Perceivable

  • All images have meaningful alternative text
  • Color is never the only indicator of meaning — icons and text labels accompany color-coded severity in alerts
  • Contrast ratios meet WCAG 2.2 AA minimums: 4.5:1 for normal text, 3:1 for large text
  • Minimum text sizes: 16px for body text, 14px for supporting text
  • All chart data is available in tabular format, not only as visualizations
  • AI-generated content is distinguishable from static content via visual badge and aria-label

Operable

  • Skip-to-content link on every page
  • Full keyboard navigation — all interactive elements reachable via Tab
  • Focus-visible indicators: 3px solid outline with 3px offset on all interactive elements
  • No keyboard traps
  • Map components include keyboard navigation and text descriptions
  • All form inputs have associated labels

Understandable

  • Logical heading hierarchy: one H1 per page, sequential H2 and H3 nesting
  • Plain-language weather translations (aviation weather decoded from pilot shorthand)
  • Clear error messages with retry options and fallback to cached data
  • Consistent navigation across all pages
  • Weather disclaimer visible on every alert

Robust

  • Semantic HTML: nav, main, header, footer, section, article
  • aria-current="page" on active navigation links
  • Alert banners use role="alert" and aria-live="polite" for dynamic updates
  • No autoplay media
  • prefers-reduced-motion respected — all animations and chart transitions disabled
  • Screen reader compatible (tested with NVDA, JAWS, VoiceOver)

Oracle-specific accessibility features.

  • All weather charts include toggle-accessible data tables for screen readers
  • Alert severity communicated through color, icons, and text labels — never color alone
  • AI-generated forecast interpretations marked with provenance badges and aria-labels
  • Map visualizations include text descriptions of displayed climate data
  • Climate trend data available in both chart and tabular formats
  • All threshold configuration forms include associated labels and clear instructions
