Telegram is available on the Google Play Store and Apple App Store. Upon installation, users can configure privacy features to enhance security. The “Secret Chats” feature uses end-to-end encryption, making messages readable only by the intended recipients, and supports self-destructing messages for additional privacy. Users should also activate “Two-Step Verification,” which requires a password and an SMS code for account access. Telegram’s privacy settings offer control over who can view profile details, last seen status, and phone number, providing comprehensive personal data management.
