AccessIQ — WCAG Accessibility Scanner, Heatmap & Behavior Analytics

AccessIQ is a free WordPress accessibility plugin that combines three tools most sites pay separately for — a full WCAG 2.1 & 2.2 accessibility scanner, a self-hosted click heatmap engine, and behavior analytics — all inside a single dark-themed dashboard, with no data ever leaving your server.

No API keys. No subscriptions. No third-party services for core features.

Why WordPress Sites Need an Accessibility Scanner

ADA and EAA lawsuits are rising. Any publicly accessible website can be targeted — and “we didn’t know” is not a legal defense. WCAG 2.1 compliance is increasingly required by law across the US, EU, and UK.

Inaccessible sites lose real users. 1 in 4 adults has a disability that affects how they use the web. An inaccessible checkout button or unlabeled form field directly costs you conversions.

Most tools only tell you there’s a problem. AccessIQ shows you exactly which element failed, why it failed, and what to fix.

Privacy & Data

AccessIQ stores all data in your own WordPress database. No scan results, click events, or session data are sent to external servers.

The WCAG scanner runs client-side in your browser — it loads your page locally and sends results via AJAX to your own database. Nothing leaves your server.

The plugin loads fonts from Google Fonts (DM Sans, DM Mono for admin; Lexend for the frontend widget). See the External Services section for details.

External Services

This plugin does not send scan, click, or session data to external servers. All data is stored in your WordPress database.

Google Fonts

AccessIQ loads typefaces from Google Fonts (fonts.googleapis.com):

1. Admin screens — DM Sans and DM Mono load on AccessIQ admin pages.
2. Frontend widget — Lexend loads on public pages when the accessibility toolbar is enabled.

When fonts are requested, the visitor’s browser sends a standard HTTP request to Google servers, which may include the visitor’s IP address, browser user-agent, and referring page URL.

Privacy Policy

AccessIQ stores the following data in your WordPress database only:

Click Events (Heatmap): X/Y coordinates, CSS element selector, page URL, timestamp, device type.

Sessions (Behavior Analytics): Page URL, session duration, device type, timestamp, bounce status.

Scan Results: Page URL, WCAG violations, compliance score, scan timestamp, WCAG level.

What we do NOT collect: IP addresses, usernames, email addresses, cookies, or any personally identifiable information (PII).

No data is sent to third-party servers. The WordPress admin loads fonts from Google Fonts (see External Services). You can delete all AccessIQ data by deactivating and deleting the plugin.

For heatmap and analytics tracking, we recommend adding a disclosure to your site’s privacy policy informing visitors that anonymous click and session data is collected for site improvement.
