About

OUT MESSENGER

Read full description

OUT is a private messenger for conversations that leave no trace. Say what you mean, read it, and let it go. Messages live only in OUT's working memory on your iPhone, vanish 10 minutes after they are read, and are never saved to a chat archive, a backup or your photo library. MESSAGES THAT LEAVE NO TRACE • Every message disappears 10 minutes after it is read. Unread messages wait up to 24 hours. • Delete a message for everyone and see it confirmed as erased from both phones. • Notifications never contain message text. SCREENSHOTS COME OUT DARK • A screenshot or screen recording of OUT shows a dark screen, not your chat. • If someone takes a screenshot in your conversation, you are told. NO PHONE NUMBER • Your OUT ID is created on your iPhone. Choose a name and start talking. • Share your name or a private invitation only with the people you choose. ENCRYPTED END TO END • Every conversation is end-to-end encrypted, with post-quantum protection for the keys. • Compare safety codes with a friend to be sure it is really them. • Our servers relay encrypted messages they cannot read and delete them once delivered. YOUR PEOPLE, YOUR GALAXY • Everyone you talk to becomes a planet around you. The people you talk to most orbit closest. • Private groups, photos, voice messages and PDF files, all disappearing like your messages. • A calm design for dark and light mode. SAFE FOR EVERYONE • Block or report anyone in seconds. Reports are reviewed within 24 hours, and accounts that send objectionable content are removed. • Emergency erase clears OUT from your iPhone instantly. OUT protects what happens inside the app. It cannot stop someone from photographing their screen with another camera, so share wisely. Questions or feedback: info@outmessenger.com
