Is Platstack: The Save button for the internet safe?

Low risk

Platstack lets allowed web pages request the full HTML, URL, title, and favicon of every open tab.

When an allowed external page sends the getWindowTabs message, the extension queries the current window's tabs and returns each non-chrome tab's page HTML, URL, title, and favicon. The production allowlist includes Platstack domains, a Heroku staging domain, and http://localhost:3000 pages, so those pages can receive this tab data.
