"Signal" - what's that?

"Signal"Is a free messenger available for the desktop, Android and iOS. Security experts worldwide recommend the crypto messenger because it collects only a little data of its users. In addition, "Signal" obscures all data with end-to-end encryption. This means that in principle no one can follow chats and phone calls. In addition, it is up to you to decide within which time span sent messages will be deleted. "Signal" contains no ads or trackers and is therefore actually a completely secure messenger.
