• Telegram is a cross-platform chat app with enhanced privacy and encryption.
• Most messages are encrypted from client to server, while Secret Chat messages are encrypted from end to end.
• Telegram also allows you to have group chats and send self-destructing messages.
• When using the Secret Chat mode, all communication is encrypted from beginning to end, making it virtually bulletproof. End-to-end encryption is also available in apps like WhatsApp and Signal.
• Secret messages can be set to self-destruct after a certain amount of time, increasing their security. You can do something similar on apps like Snapchat, Instagram, and Facebook Messenger.
