Is Siteimprove Accessibility Checker safe?
Siteimprove Accessibility Checker serializes the active tab's page content and URL for local accessibility audits.
When you start an audit from the extension popup, it injects scripts into the selected tab and copies the page's DOM, text, attributes, styles, viewport details, and URL into the extension. The bundled Alfa rules evaluate that snapshot locally and show results in the extension UI; the confirmed claim does not identify any external recipient.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 5 hostnames
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
