For those interested in maximum privacy, Telegram offers Secret Chats. Secret Chat messages can be programmed to self-destruct automatically from both participating devices. This way you can send all types of disappearing content — messages, photos, videos, and even files. Secret Chats use End-to-End Encryption to ensure that a message can only be read by its intended recipient.
We keep expanding the boundaries of what you can do with a messaging app. Don’t wait years for older messengers to catch up with Telegram — join the revolution today. Millions choose Telegram for its speed, security, and powerful features that enhance daily communication.
