@MaybeMyMonkeys @lienrag @Mer__edith it literally doesn't matter. At the point that something is actively detecting that signal is installed and trying to get data in the machine it can do anything. Screenshots, keylogger, access files, intercept the network, etc. It's basically not possible to have Signal app installed and running in windows in a way that doesn't allow malicious things running from getting wtv it wants. The whole thing is blown out of proportion.
Don't use it on windows.
