What could happen if something went wrong
Not a whole lot, from what we can tell. Signal's open-source end-to-end encryption is lauded by many security professionals. And Signal won't track you or sell your data to strangers who could use it to target you with weird ads. It's always possible that buddy you're video chatting with could screenshot your chat before you've combed your hair. But hey, that's true for every video call app, so comb your hair before you take that video call!
