IIRC one could use Google Now with voice recordings off and the extra-spying setting of "web and app activity" off (though web and app activity had to be on for many features). All this must now be on for the assistant, as you say.

I did try out Google Now for a time due to having an Android Wear watch and found that as time went on more functionality required the turning on of these settings. One particular oddity for a time was that "OK Google, Navigate Home" would produce only a complaint about web and app activity being off, but "OK Google, navigate to $HOME_STREET, $HOME_TOWN" was fine.

I've abandoned Android Wear because of this.
