If I set a K2 Item to registered, ignoring active hacking, will this prevent that item including its text being viewed by non-registered users in any way, e.g. through Google?

AFAIK, the answer is yes.

Google needs to be provided with login credentials to access such content, I remember there was a way to grant Google access to non-public or not free content, so it can't access or display such content as long as you have not granted it the permissions to do it.

That's what I was hoping, thanks!

If someone could confirm this (since I think you indicated you weren't 100% sure?), I would be very glad!
