Pavel Durov on Signal

hashcatHitman: > This does make me wonder, though: is there any mechanism in Signal we can use to prevent our message contents from appearing in the recipient’s notifications regardless of how they have configured the setting to do so? No, and there won’t be. Regardless of service used, the only way is that all participants in conversation are equally aware of risks and consequences. It is similar with 3rd party apps and matrix bridges. You can not be sure what other side is using on their device. Even you agree to use e.g. Signal, without notification messages, they can install some malware app, leave unlocked phone on train station, etc. Maybe solution is to call (via Signal) and say important thing, or even better, meet in person.
