Yoo

Yo is a messaging app that puts privacy at its core. It's free and easy to use, with strong end-to-end encryption that keeps your communications completely private. Send text messages, voice messages, photos, videos, GIFs, and files for free, as Yo uses your phone's internet connection, so you avoid SMS and MMS charges. Connect with your friends via crystal-clear, encrypted voice and video calls, with support for group calls of up to 50 people. Stay connected in group chats with up to 1,000 people, control who can post, and manage group members through admin permissions settings. Share stories of photos, text, and videos that disappear after 24 hours, with privacy settings that put you in complete control of who sees each story. Yo is designed with your privacy in mind; we don't know anything about you or who you're talking to. The app relies on an open-source, widely tested encryption protocol, so we can't read your messages or listen to your calls, and neither can anyone else. There are no backdoors or data collection.
