Telegram is available for download on both Android and iOS devices via the Google Play Store and Apple App Store. After installing the app, users should configure their privacy settings for enhanced security. Telegram offers “Secret Chats” with end-to-end encryption, ensuring that only the intended recipients can read messages. Users can also activate “Two-Step Verification,” which requires a password and an SMS code for added protection. Privacy settings allow users to control who can view their profile photo, last seen status, and phone number, offering comprehensive control over personal information.
