Is Tungsten Power PDF safe?

Tungsten Power PDF reads page cookies and full DOM content from any HTTP/HTTPS page and forwards them to the locally installed native host.

When a user triggers PDF conversion, the extension's content script collects document.cookie and a serialized copy of the page DOM, then passes both to the background script, which relays them to the Tungsten Power PDF native host via native messaging. The content script runs on all http://*/* and https://*/* pages, so cookies from any visited site are in scope for collection during a conversion request.
