Deque axe - Accessibility Testing Consent Settings

Back to Vendor Library

Overview

Deque axe is the most widely adopted web accessibility testing toolkit, used by developers and QA teams to audit web pages against WCAG (Web Content Accessibility Guidelines) standards. Its scripts scan the page DOM to identify accessibility violations — missing alt text, insufficient color contrast, improper ARIA usage, and keyboard navigation issues — and report findings in developer tools or monitoring dashboards.

What This Script Does

Deque's axe scripts operate in different modes depending on deployment:

axe-core library: The open-source axe-core JavaScript library runs accessibility audits against the live DOM. It traverses page elements, checking each against WCAG 2.0/2.1/2.2 rules and best practices. Results are returned as structured JSON with violation details, affected elements, and remediation guidance.
axe DevTools: The browser extension variant injects auditing scripts into the page for developer-initiated testing sessions. It does not persist between sessions or affect production visitors.
axe Monitor: The SaaS monitoring variant may load a lightweight script on production pages to perform periodic automated accessibility scans and report results to Deque's dashboard.
No cookies: axe does not set tracking cookies or collect personal data about site visitors. Its data collection is limited to DOM structure analysis for accessibility compliance.
No network tracking: axe-core runs entirely client-side. axe Monitor sends scan results (page structure data, not visitor data) to Deque's servers.

Consent & Compliance

Deque axe falls under the functional consent category. It provides a development and compliance function (accessibility auditing) that does not involve tracking or profiling site visitors.

Under GDPR and ePrivacy, axe scripts do not access personal data or set cookies on visitor devices. The DOM analysis examines page structure, not visitor behavior. If axe Monitor sends scan data to Deque's servers, this contains page structure information, not personal data.

Under CCPA/CPRA, axe does not collect, sell, or share personal information about site visitors.

Should You Block This Without Consent?

No. Deque axe performs accessibility auditing with no tracking, no cookies, and no personal data collection. Blocking it would disable accessibility monitoring and compliance scanning. In production deployments (axe Monitor), the script serves the site operator's legal obligation to maintain accessible content under ADA, EAA, and other accessibility regulations.

Is Deque / axe GDPR compliant?

Deque / axe typically loads functional trackers, which are not strictly necessary for your site to work. Under the GDPR and the ePrivacy Directive, non-essential cookies and trackers must stay blocked until a visitor gives clear opt-in consent. So Deque / axe can be fully GDPR compliant, but only if your site holds its scripts until consent is granted and lets visitors decline just as easily. Compliance depends on how your site loads Deque / axe, not on Deque / axe itself.
