Is Docsvision Windows Client Launcher safe?

Docsvision Windows Client Launcher reads DOM parameters from Docsvision pages and forwards them to a local native messaging host.

When the extension detects a Docsvision web application page (identified by specific DOM element IDs and a title containing 'Docsvision'), it collects <param> element name-value pairs and sends them to the locally installed com.docsvision.navigator native application. After forwarding the data, the background script closes the originating browser tab automatically. No data is sent to remote servers; all communication goes through the native messaging channel to the locally installed Docsvision client software.
