• Say what you want – State-of-the-art end-to-end encryption (open source Signal Protocol™) keeps your chats secure. Privacy is not an optional mode, it’s the way Signal works. Every message, every call, every time.

• Feel free – Signal is a fully independent 501c3 nonprofit. The development of the software is supported by users like you. No ads. No tracking. No jokes.

• Be yourself – You can use your existing phone number and contacts to securely communicate with your friends.

• Speak – Whether across town or across the ocean, Signal’s enhanced audio and video quality will make friends and family feel closer to you.

• Whisper in the shadows – If you can’t stand the sight of the light, switch to the dark theme.

• Sound familiar – Choose a different alert for each contact, or mute the sounds altogether. You can experience the sound of silence, about which Simon and Garfunkel wrote a popular song in 1964, at any time by selecting the notification sound setting “None”.

• Capture this – Use the built-in image editor to draw, crop, rotate, etc. on your sent photos. There’s even a writing tool where you can add even more to your 1,000 word photo.
