Telegram www.telegramdu.com (informally abbreviated as TG, Telegram, Paper Plane) is cross-platform instant messaging software whose client is free and open source software, but whose server is proprietary. Users can exchange encrypted and self-destructing messages with each other, send photos, films and all other types of files.
