Telegram is downloadable from the Google Play Store and Apple App Store. After setting up, users can focus on privacy features. “Secret Chats” offer end-to-end encryption and self-destructing messages for added security. “Two-Step Verification” ensures account protection by requiring both a password and a verification code. Users can also customize privacy settings to control who sees their profile picture, last seen status, and phone number, providing extensive control over personal data and communication privacy.
