A11yBridge – Accessibility Toolkit (AI optional)

A11yBridge adds a visitor-friendly accessibility toolbar to your WordPress site. It helps users adjust how your content is displayed and navigated, and can optionally simplify text with AI in multiple languages and levels.

Key features:

• Font size controls
• Focus mode (reduce distractions / highlight content area)
• Contrast adjustments
• Color-blindness filters / color adjustments
• Keyboard navigation support
• Text-to-speech (TTS)
• AI-powered text simplification (multiple levels and languages)

Important note: This plugin can improve usability and accessibility, but it cannot guarantee full compliance with WCAG or any specific legal requirement. Always test your site with real assistive technologies and accessibility audits.

AI features (optional)

AI text simplification is processed on external servers. Cloud features are disabled by default and are only used after the site owner enables them (or activates a license). Any usage limits are enforced by the external service and depend on the service subscription associated with the installation. All non-AI accessibility tools (toolbar, contrast, focus mode, keyboard support, text-to-speech) work without any AI connection.

The plugin itself does not lock or restrict built-in/local functionality based on a license key, trial period, or local usage counters. If the service quota is exceeded, the service returns an error response and the plugin displays a notice.

External Services / Data Transmission

This plugin can optionally connect to A11yBridge backend services to provide AI text simplification and related service operations (e.g., quota management, license activation, abuse prevention). For WP.org compliance, it does NOT contact external servers by default. External requests happen only after explicit admin opt-in (cloud enabled / AI feature enabled) or after the admin activates a license key.

Service endpoint(s):

• https://a11ybridge.de/wp-json/a11ybridge/v1
  • /license/status (read current license/installation status)
  • /license/activate (activate/bind license to this site)
  • /license/domains/delete (remove domain binding from license)
  • /free/status (free-tier quota status, only after admin opt-in)
  • /chat/simplify (AI text simplification, only when triggered by the user)

What data may be transmitted (depending on enabled features):

Local storage / Cookies on the site where the plugin is installed:

To remember accessibility preferences for visitors, A11yBridge stores settings in the visitor’s browser storage and (for guests) may also store a pseudonymous guest identifier.

Browser storage (localStorage) keys used by the frontend may include: * a11ybridge_plugin_settings (visitor accessibility preferences) * A11YBRIDGE_USER_LOCAL_V1 (visitor feature flags/preferences) * a11ybridge_colorMode (display mode) * a11ybridge:consent:text_simplify: (stores the visitor’s consent decision for AI text simplification prompts)

Cookie (functional): * a11ybridge_guest_id (random pseudonymous ID for guest settings; used to associate guest preferences stored on the same WordPress installation; expires after 30 days; SameSite=Lax; Secure on HTTPS)

This storage is used only to provide the requested accessibility features and is not used for advertising or cross-site tracking. Site owners should document this storage in their privacy/cookie documentation as required by applicable law.

• Selected text submitted by the user for AI text simplification (only when the user triggers simplification)
• Pseudonymous installation ID
• Domain/host (only after admin opt-in or license activation)
• License key hash (pseudonymous, if a license is used)
• Service-side usage/quota accounting
• Request metadata (no IP forwarding; IP may be processed in server/security logs depending on configuration)

Purposes:

• Provide AI text simplification on request
• Service-side quota enforcement and account/service management
• Abuse prevention, security and troubleshooting

Infrastructure / Hosting:

• Backend services are hosted on a Hetzner server located in Nuremberg, Germany.
• Subscription payments (if used) are handled by Paddle (Merchant of Record). No payment card data is handled by this plugin.

Privacy & Terms:

Privacy Policy: https://a11ybridge.de/datenschutzerklaerung/ Terms of Use: https://a11ybridge.de/allgemeine-geschaftsbedingungen-agbagb/

User guidance:

• Disable AI features in Settings to avoid any text being transmitted to external servers.
• Avoid submitting sensitive or personal data for AI processing.
• A11yBridge does not sell user data and does not use transmitted content for advertising or cross-site tracking.
