Description
Privacy is possible, Signal makes it easy.
Using Signal, you can communicate instantly while avoiding SMS fees, create groups so that you can chat in real time with all your friends at once, and share media all with complete privacy. The server never has access to any of your communication and never stores any of your data.
• Say Anything - Signal uses an advanced end to end encryption protocol that provides privacy for every message every time.
• Open Source - Signal is Free and Open Source, enabling anyone to verify its security by auditing the code. Signal is the only private messenger that uses open source peer-reviewed cryptographic protocols to keep your messages safe.
• Be Yourself - Signal uses your existing phone number and address book. There are no separate logins, usernames, passwords, or PINs to manage or lose.
• Group Chat - Signal allows you to create encrypted groups so you can have private conversations with all your friends at once. Not only are the messages encrypted, but the Signal server never has access to any group metadata such as the membership list, group title, or group icon.
• Fast - The Signal protocol is designed to operate in the most constrained environment possible. Using Signal, messages are instantly delivered to friends.
• Speak Freely - Make crystal-clear phone calls to people who live across town, or across the ocean, with no long-distance charges.

Customer Reviews
Private but not entirely
Considering you are required to use a phone number to login/authenticate your account it isn't really private because anyone who has your phone number knows you're using the application. That's not privacy, that's a blatant phone book! Also, I've been asking for a couple of years but no changes have been made to the notification sound. It's simple, OWS: change the default sound to something less annoying/obtrusive or give us custom sounds, please.
Time Stamp
Not sure why but quite often texts come through without the date/time. We're using this app and creating a report/log but that's hard to do when the times aren't always showing. Can you please fix this? Thank you! :)
Ignore the Wire shill, Signal is great!
They also provided the encryption behind Whatsapp.
Signal recently received a subpoena for information on two users. There was no real info available to provide the government due to Signal's encryption and policies. Signal is very private and secure!
