If Recall is such a big problem for that, then what of Thunderbird which would give your entire set of emails to anyone with read permissions, or Firefox which would give your email credentials and in turn your entire set of emails to anyone with read permissions. Unless you make a habit of going through all of your email archive one by one, that information is not going to be in recall. Same thing for Signal, Messenger, et al. Recall sees everything you see. Your credentials and local storage, cookies, cache, et al. see everything you see, and everything you don't see, and things you see on other devices too, and etc etc. - - - "Implemented safely" doesn't include security through obscurity. Past having an encrypted home directory, the only practical way to make it more secure than it currently is would be a separate device that records from tapping your monitor's cables.
