Expand a finding to inspect its elements and guidance. Choose Open side panel to keep the results visible while reviewing the page. Re-scan after changing the page or its layout. PRIVACY AND PERMISSIONS Scans run locally in your browser when you start them. Results may be stored temporarily in Chrome session storage. Reports are not uploaded by the extension; you choose whether to export or copy them. The bundled testing engine may request the page's stylesheets or media to evaluate relevant checks. Optional site access supports embedded cross-origin frames and continued side-panel scanning after navigation. Automated checks do not certify accessibility or legal compliance. Keyboard testing, screen-reader testing, and human review remain important. Chrome restricts scanning on internal browser pages and the Chrome Web Store. Side-panel features require Chrome 116 or later. Learn more: https://getadascanner.com/
