Accessibility Statement

Effective Date: April 19, 2026

Trellis is a product of Trellis Ads LLC, based in Utah, United States.

1. Our Commitment to Accessibility

Trellis is committed to ensuring digital accessibility for all users, including those with disabilities. We strive to conform to the Web Content Accessibility Guidelines (WCAG) 2.2, Level AA, as published by the World Wide Web Consortium (W3C).

Accessibility is an ongoing effort, and we treat it as a core product requirement.

2. Conformance Status

Trellis is partially conforming with WCAG 2.2 Level AA.

"Partially conforming" means that some parts of the content may not fully conform to the accessibility standard. We address gaps as they are identified.

3. Accessibility Features

Current accessibility features:

• Skip-to-main-content navigation link -- allows keyboard users to bypass repeated navigation
• Semantic HTML5 structure with proper landmark regions (header, nav, main, footer)
• Logical heading hierarchy (h1 through h6) for clear document structure
• ARIA labels on interactive elements and navigation components
• Keyboard navigability across the application
• Visible focus indicators on all interactive elements
• Dark mode support that respects operating system preference via prefers-color-scheme
• Responsive design from mobile (320px) to desktop
• Color contrast ratios meeting WCAG AA standards (4.5:1 for normal text, 3:1 for large text and UI components)
• Form inputs with associated labels for clear identification
• Error messages that are clear and actionable
• Toast notifications that are announced to screen readers via ARIA live regions

4. Known Limitations

• PDF audit reports: Generated PDFs may not be fully accessible to screen readers. We can provide report content in alternative formats (plain text, HTML) upon request.
• Data visualization charts: Some charts may lack comprehensive text alternatives. We are working to add descriptive summaries to all charts.
• Third-party embedded content: Content from external services may not meet our accessibility standards and is outside our direct control.

5. Technologies We Rely On

The accessibility of Trellis depends on the following technologies:

• HTML5
• CSS3 (via Tailwind CSS)
• JavaScript (React 19 / Next.js 16)
• WAI-ARIA 1.2
• shadcn/ui component library (built on Radix UI, designed with accessibility as a core principle)

6. How We Test

Our accessibility testing approach includes:

• Keyboard-only navigation testing across all application flows
• Automated scanning with axe-core and Lighthouse
• Manual screen reader testing with VoiceOver (macOS)
• Color contrast verification against WCAG AA thresholds using automated and manual tools
