LOCAL BOUNDARY

The browser talks to your workstation.

The pairing code and resulting credential stay in this page's memory. The static TrayHop website does not receive them.

PRIVACY AND SCOPE

A diagnostic, not a print test.

No job submission

This page has no print action and does not call the TrayHop jobs endpoint.

Memory only

The credential is not written to browser storage. Reloading or leaving the page clears the local session.

No site telemetry

The check makes direct browser requests to loopback. This static page has no analytics and does not upload the results.
