Signal’s advanced privacy-preserving technology is always enabled, so you can focus on sharing the moments that matter with the people who matter to you. Send and receive high-fidelity messages, participate in HD voice/video calls, and explore a growing set of new features that help you stay connected. It usually triggers this usage when the app wakes up.Millions of people use Signal every day for free and instantaneous communication anywhere in the world. It can be anywhere above 500 MB per hour, depending on how active you are and the media you send. Since Signal doesn’t use MMS or SMS methods to communicate, you’ll use the standard data for sending texts, images, videos, or video calling your friend. The only way anyone can discover your number is when you message them or make a call, but the app doesn’t share your number without your permission. Signal doesn’t make it its business to obtain or use your stored phone numbers in any way. The only data available to you are the contacts on your mobile phone. Not only is the government unable to read it, but even the parent company has no means to view it. In essence, it sends a communication in such a manner that only the receiver’s device can access it.

Thanks to its end-to-end encryption, Signal is one of the safest messaging apps available for Android.

Today, it’s still used as one of the most secure communication systems. These two apps merged in 2014 to become Signal, with the Whatsapp co-founder Brian Acton and Marlinspike acquiring it in 2018. Whisper Systems launched two programs in 2010: TextSecure for written chats and RedPhone for calls. The encrypted Signal application for Android is a secret messaging system designed to protect your privacy.
