Important — best-effort accessibility
- BEST EFFORT: HCODX is committed to accessibility but cannot guarantee full compliance with every accessibility standard or compatibility with every assistive technology.
- NO WARRANTY: The service is provided "AS IS." We make no warranties regarding accessibility compliance or fitness for use by any specific individual.
- NO LIABILITY: We are not liable for any damages or losses arising from accessibility barriers, incompatibility with assistive technologies, or any inability to use any part of this service.
- THIRD-PARTY LIMITATIONS: Third-party libraries (CodeMirror, Monaco, PDF.js, etc.), embedded tools, and advertisements integrated into this site may have their own accessibility limitations that we cannot fully control.
- USER RESPONSIBILITY: You are responsible for determining whether HCODX meets your specific accessibility needs before relying on it for any purpose.
1. Our commitment
HCODX provides a comprehensive set of free browser-based tools — calculators (financial, health, math, date, pets), code editors, online compilers, AI utilities, document viewers, formatters and many more — and we want every one of them to be usable by every visitor. There is no signup, no upload, no payment required to use any tool, which removes whole categories of accessibility friction up front.
2. Standards we target
We aim to conform to the following accessibility standards on a best-effort basis:
- WCAG 2.1 Level AA — Web Content Accessibility Guidelines (W3C)
- Section 508 — U.S. federal electronic accessibility requirements
- EN 301 549 — European standard for ICT accessibility
Current compliance status
- WCAG 2.1 Level A: substantially compliant
- WCAG 2.1 Level AA: partially compliant — ongoing improvements
- Section 508: substantially compliant for static content; partially compliant for interactive editor features
3. Accessibility features
HCODX currently includes the following accessibility features across the site:
Keyboard navigation
Core features, search, filter chips, calculator inputs, and tool buttons are reachable and operable with keyboard only.
Screen reader support
ARIA labels on interactive elements; semantic HTML landmarks; descriptive button and link text.
Dark / light themes
Manual toggle and automatic prefers-color-scheme support. High-contrast palette in both themes.
Scalable text
Interface respects browser zoom up to 200% without horizontal scrolling on common viewports.
Alternative text
Descriptive labels on icons and non-decorative images; aria-hidden on purely decorative icons.
Visible focus indicators
Clear focus outlines on all interactive elements for keyboard users.
Skip links
Skip-to-content links on main pages so screen-reader and keyboard users can bypass navigation.
Semantic structure
Proper heading hierarchy (H1 → H2 → H3), landmark regions (header / main / footer / nav), labeled form fields.
4. Known limitations
We are transparent about areas where accessibility is currently imperfect:
- Code editor complexity: some advanced editor interactions (multi-cursor, drag-and-drop block selection) may require pointer input. Keyboard alternatives are provided for most common actions.
- Third-party libraries: open-source libraries used in the editor and viewer tools (CodeMirror, Monaco, PDF.js, syntax-highlighting libraries) may have accessibility gaps we cannot fully control.
- Live preview frame: the editor's live preview renders your HTML code; its accessibility depends on the code you write.
- Dynamic content: some calculator and tool outputs update as you type; not all updates are currently announced via
aria-liveregions (improvement in progress). - Color usage: some interface elements use color as a primary indicator (e.g. "Healthy weight" green, "Obese" red badges in BMI results); text alternatives are provided where possible but may not cover every case.
- Third-party advertisements: when ads load, their accessibility is governed by the advertising networks and is outside our control.
5. Supported assistive technologies

- TalkBack (Android)
- Orca (Linux)
Other assistive technologies
- Voice recognition software (Dragon NaturallySpeaking / Dragon Professional)
- Keyboard-only navigation
- Browser magnification and zoom
- High-contrast OS modes and Windows High Contrast Mode
Recommended browsers for best accessibility
- Chrome 90+

6. Feedback and reporting barriers
We actively welcome accessibility feedback. If you encounter a barrier that prevents you from using any part of HCODX, please tell us — every report helps us prioritize the next round of improvements.
Accessibility contact: accessibility@hcodx.com
Subject line: Accessibility Issue — [brief description]
Response time: We aim to respond within 5 business days.
When reporting an issue, it helps a lot to include:
- A description of the barrier you encountered
- The URL of the page where you encountered it
- Your browser, operating system, and assistive technology (e.g. "Chrome 124 + NVDA 2024.1 on Windows 11")
- Steps to reproduce the issue
- What you were trying to do
7. Ongoing improvement
We are committed to improving accessibility over time through:
- Periodic manual testing with keyboard navigation and screen readers
- Automated accessibility scanning during development (axe-core, Lighthouse)
- Reviewing and addressing user-reported accessibility barriers
- Monitoring updates to WCAG and related standards
- Tracking accessibility across the full set of tools as we add new ones
Planned improvements
aria-liveregions for dynamic calculator output and tool result updates- Enhanced keyboard navigation within the code editor
- Expanded ARIA labelling across every calculator page
- Regular accessibility review cycle (quarterly)
- Reduced-motion preference support (
prefers-reduced-motion) across animated UI
8. Educational and classroom use
HCODX is widely used for learning and teaching — web development, math, finance, science. Educators using HCODX in classroom settings should:
- Assess each tool's suitability for their students' specific accessibility needs
- Provide alternative instruction methods where HCODX cannot fully accommodate a student's needs
- Contact us with specific classroom accessibility requirements — we will do our best to help
