Is Remarkable Chrome Extension safe?

Clean risk

Remarkable Chrome Extension sends each page's hostname and path to its backend when it opens its comment UI.

When an HTTP or HTTPS tab finishes loading, the extension injects its comment interface into the page. As that interface mounts, it reads the current page's hostname and path and posts them to the Remarkable backend to look up comments, adding a stored authorization token if the user is logged in.
