Features

End-to-End Encryption: Signal uses the Signal Protocol, an advanced encryption algorithm, to protect all communications from eavesdropping. Messages are encrypted on the sender's device and decrypted only on the recipient's device, ensuring that no third party can intercept or read them.

Self-Destructing Messages: Users can set messages to self-destruct after a specified amount of time, ensuring that sensitive information is not retained indefinitely.

Disappearing Typing Indicators: Signal hides typing indicators by default, preventing others from knowing when you are typing a message.

Privacy-Focused Features: Signal offers a range of privacy-focused features, including:

* Incognito Keyboard: Blocks the keyboard from accessing user data.
