Is Postlight Reader safe?

Clean risk

Postlight Reader sends the current article's domain to Google's favicon service when Reader view opens.

When you open Postlight Reader from its toolbar or context-menu action, its reader UI builds a favicon image URL using the parsed article domain. That image is loaded from Google's www.google.com/s2/favicons service, which tells Google the domain of the article being viewed.
