12. Consider Using a VPN (Optional):

A VPN (Virtual Private Network) can encrypt your internet traffic and hide your IP address, providing an extra layer of privacy when using Telegram, especially on public Wi-Fi networks.

Cloud Chats: Telegram stores cloud chats (regular chats, groups, channels) on its servers to enable syncing across devices. These are encrypted in transit and at rest, but Telegram technically has access to the decryption keys.
Secret Chats: As mentioned, these are not stored on Telegram's servers and are end-to-end encrypted.
Metadata: Telegram collects some metadata, such as your phone number, contacts (if synced), IP address, and device information. Their privacy policy outlines how this data is used.
In summary, to secure your Telegram data effectively:

Prioritize Secret Chats for sensitive conversations.
Enable Two-Step Verification.
Customize your privacy settings.

Regularly review active sessions.
Use a local passcode lock.
Practice safe sharing habits.
Keep your app updated.

Phone Number: Go to Settings > Privacy and Security > Phone Number. Choose "Nobody" to hide your number from everyone. You can then set "Who can find me by my number?" to "My Contacts" so that people you know can still find you.
Last Seen & Online: Navigate to Settings > Privacy and Security > Last Seen & Online. Set this to "Nobody" or "My Contacts" to limit who can see when you were last active. Remember that you will still appear online briefly when you are actively using the app.
Profile Photo: In Settings > Privacy and Security > Profile Photo, choose "My Contacts" or "Nobody" to control who sees your profile picture.
Forwarded Messages: Go to Settings > Privacy and Security > Forwarded Messages and set it to "My Contacts" or "Nobody" to prevent your profile from being linked to messages you forward.
Calls: Under Settings > Privacy and Security > Calls, you can choose who can call you ("My Contacts" or "Nobody"). You can also disable "Peer-to-Peer" to route calls through Telegram's servers, hiding your IP address (though this might slightly reduce call quality).
Groups & Channels: In Settings > Privacy and Security > Groups & Channels, decide who can add you to groups ("My Contacts" is a good option to avoid spam).
