In that case, yes, with some caveats. Be mindful of your list of Matrix devices because that is something all participants can see. Otherwise, Matrix will allow you preserve basic anonymity with respect to the other participants (but not with respect to the server) with solid encryption. Also bear in mind that Matrix is built on the premise of storing all messages server-side indefinitely by default (in end-to-end encrypted form and with regular key rotation so forward secrecy is preserved). Of course, forward secrecy does not help if the participants retain all keys indefinitely and subsequently leak them. I think disappearing messages are in the works.
