I'm trying to find out privacy settings behind the wifi chat offered by... Samsung? Its built into my S10e as an additional chat service with little to no information about it. It's free and enables chat over WiFi and to groups of users who have the feature enabled. It also enables Android users to see when others who have the service are typing like on the iPhone.
My concern is privacy. If it's free, how do I know that I'm not the product here?
