I doubt it. All of the AI stuff is local, and I don’t think there’s any network interaction other than checking for updates (you could check that, or block it with something like RethinkDNS or NetGuard), so there wouldn’t be any way for them to get your data. The other app of theirs I use, Grayjay, doesn’t even sync between instances of their app across devices, so I think it’s fair to say they explicitly avoid touching the network whatsoever.
