Part 4: Privacy and Security Features

Telegram is famous for its focus on privacy, but it is important to know which features provide which level of security.

1. Cloud Chats (Standard)

All your standard one-on-one chats and group chats are Cloud Chats.⁴⁰
They use Server-Client Encryption and are stored on the Telegram cloud.⁴¹
Pro: They sync instantly across all your devices, and your history is never lost.⁴²
Con: While encrypted in transit and storage, Telegram technically holds the encryption key on its server, meaning messages could be accessed by Telegram in extraordinary circumstances.⁴³

2. Secret Chats (Maximum Security)⁴⁴

Creation: Tap the New Message icon ⁴⁵$\rightarrow$ New Secret Chat.⁴⁶
Encryption: These chats use End-to-End Encryption (E2EE).⁴⁷ This means the encryption key is only held on the devices of the sender and recipient. Telegram cannot read these messages.⁴⁸
Features:
- Self-Destruct Timer: Messages, photos, and files can be set to automatically delete after a set time once the recipient reads them.⁴⁹
- No Forwarding: Messages cannot be forwarded outside the Secret Chat.
- Screenshot Warning: On most platforms, the app will notify the other person if a screenshot is taken.
Con: Secret Chats are tied to the device they were started on and do not sync to the Telegram cloud or any other device.⁵⁰

3. Key Privacy Settings

Always customize your privacy settings via Settings ⁵¹$\rightarrow$ Privacy and Security.⁵²

Last Seen & Online: Control who can see when you were last active.⁵³
Profile Photos: Control who can see your profile picture.⁵⁴
Forwarded Messages: Choose who can link to your account when they forward your messages.
Calls: Control who can call you on Telegram.⁵⁵
Groups & Channels: Prevent strangers from adding you to unwanted groups.⁵⁶
Two-Step Verification (Highly Recommended): Add a second password (a “cloud password”) that is required when logging into a new device.⁵⁷ This protects your account even if someone gains access to your phone number’s verification code.⁵⁸

Part 5: Advanced Customization and Power User Features

1. Chat Folders

For users with many groups and channels, Chat Folders are essential for organization.⁵⁹

How to Use: Go to Settings ⁶⁰$\rightarrow$ Folders.⁶¹
Function: Create custom folders (e.g., “Work,” “News,” “Friends”) and assign specific chats, groups, or channels to them.⁶²
Access: The folders appear as tabs at the top of your main chat list.

2. Custom Themes and Appearance

Telegram offers deep customization options for the look and feel of the app.⁶³

Themes: Go to Settings $\rightarrow$ Chat Settings (or Appearance) to change colors, background, message bubble shapes, and fonts.
Night Mode: Easily switch to a dark theme for comfortable viewing in low light.

Telegram is free, but an optional Premium subscription unlocks extra perks:

Increased Limits: Double the limits for groups, channels, folders, pinned chats, and more.
Larger File Uploads: Increase the file upload limit from 2 GB to 4 GB.
Faster Downloads: Premium subscribers get prioritized speed.
Premium Stickers/Reactions: Access to exclusive sticker packs and reactions.
