Introduce about Signal - Private Messenger
Signal is a messaging app with privacy at its core. It is free and easy to use, with strong end-to-end encryption that keeps your communication completely private.
• Send texts, voice messages, photos, videos, stickers, GIFs, and files for free. Signal uses your phone’s data connection, so you avoid SMS and MMS fees.
• Call your friends with crystal-clear encrypted voice and video calls. Group calls supported for up to 40 people.
• Stay connected with group chats up to 1,000 people. Control who can post and manage group members with admin permission settings.
• Share image, text, and video Stories that disappear after 24 hours. Privacy settings keep you in charge of exactly who can see each Story.
• Signal is built for your privacy. We know nothing about you or who you’re talking to. Our open source Signal Protocol means that we can’t read your messages or listen to your calls. Neither can anyone else. No back doors, no data collection, no compromises.
• Signal is independent and not for profit; a different kind of tech from a different kind of organization. As a 501c3 nonprofit we are supported by your donations, not by advertisers or investors.

Download Signal - Private Messenger APK for Android
As soon as you start Signal for the first time, you'll notice its security features. There's no independent login, no username or password – the app uses your phone number and your address book, so in theory, you can't pretend to be someone you're not.
The app uses end-to-end encryption, protecting every message you send to your contacts. Whether you're talking directly to an individual or a group, all your messages are always kept absolutely private. Not even Signal's servers have access to the information of your groups.
As you'd expect, Signal lets you send all kinds of files, including pictures, videos, and audio, always protecting them with the same protocol it uses for text messages. Everything is kept absolutely safe.
Available Versions of Signal - Private Messenger
Signal is a secure and private instant messaging client that provides an additional layer of safety that other similar apps just don't have. WhatsApp, LINE and even Telegram might have more users, but they are not as safe as this app.
