every chromium embedded also uses the google dns fyi. having built a chromium embedded app it was puzzling to me that there's no way to disable that(or maybe there is and i haven't found it). i don't know if that's the case here though(since it's blocked in my firewall).

in fact most of the so called privacy aware chromium builds also leak the dns information to google.

This is not deliberate practice, it's usually hidden somewhere in the code, and unless your firewall prompts you you might not even ever notice.
