Latest Update: Signal Stories Available on iOS and Android

Now the feature is rolling out on the latest version of Signal. Update to enjoy your stories!

• Say anything

State-of-the-art end-to-end encryption (powered by the open source Signal Protocol™) keeps your conversations secure. Privacy isn’t an optional mode — it’s just the way that Signal works. Every message, every call, every time.

• Go fast

Messages are delivered quickly and reliably, even on slow networks. Signal is optimized to operate in the most constrained environment possible.

• Feel free

Signal is a completely independent 501c3 nonprofit. Development is supported by users like you. No advertisements. No trackers. No kidding.

• Be yourself

You can use your existing phone number and address book to securely communicate with your friends.

• Speak up

Whether they live across town or across the ocean, Signal’s enhanced audio and video quality will make your friends and family feel closer.

• Whisper in the shadows

Switch to the dark theme if you refuse to see the light.

• Sound familiar

Choose custom alerts for each contact, or disable noises completely. Simon & Garfunkel wrote a hit song about it in 1964, and you can experience the sound of silence whenever you want by choosing “None” as your notification ringtone.

• Picture this

Use the built-in image editing features to sketch, crop, and flip your outgoing photos. There’s even a text tool so that you can add more words to the 1,000 that your picture is already worth.

Private and Secure

Everything on Signal is encrypted, always and by default. All communications on Signal are end-to-end encrypted, which means only the people involved in the communication can see them, even the company that operates Signal cannot see the communication messages. Signal also offers other privacy features, such as self-destructing messages which will automatically disappear after a period of time.
