If you’re like most people, you downloaded Telegram because you heard it was the secure, privacy-focused messenger. But here’s the uncomfortable truth that isn’t advertised on the main download page: by default, your Telegram messages are not end-to-end encrypted.
However, this doesn’t mean Telegram’s privacy is questionable; on the contrary, it’s very secure. It just requires you to manually enable some Telegram privacy settings.
Why Isn’t Telegram End-to-End Encrypted by Default
Telegram often appears in discussions about secure messaging alongside apps like WhatsApp and Signal. Many news articles and social media posts describe Telegram as a privacy-focused platform.
As a result, users often assume every Telegram message is end-to-end encrypted, that Telegram cannot access message contents, and all chats are equally secure.
However, these assumptions are not entirely correct.
Telegram argues that requiring all chats to be end-to-end encrypted makes it much harder for users to easily restore their message history when they switch to a new device.
To solve this, some apps, like WhatsApp, offer decryptable cloud backups, which Telegram views as a privacy risk. Others forgo backups altogether.
Telegram’s solution is to offer two distinct chat types: convenient Cloud Chats and fully private Secret Chats, putting the choice in the user’s hands.
The company explains that this split helps Telegram appeal to regular users, not just activists. This ensures that simply having the app doesn’t make someone a target for government tracking in certain places.
In essence, regular cloud chats focus on features and ease of use, while Secret Chats are all about total privacy.
The One Thing You Must Do: Use Secret Chats
If you want true end-to-end encryption on Telegram, you need to start a Secret Chat. Many users never discover this feature because it is not enabled automatically.
Only the participants can access the messages. Telegram’s servers cannot read the content.
How to Start a Secret Chat
- Open Telegram.
- Open the chat with the contact.
- Tap on their name at the top of the screen.
- Select “Start Secret Chat.”
- A new chat window will open, marked with a lock icon.
What Makes Secret Chats Different
- End-to-end encryption: Telegram’s servers cannot decrypt them.
- Device-specific conversations: Messages exist only on the devices involved in that specific chat.
- No cloud storage: They do not sync to your other devices or to Telegram’s cloud.
- Additional screenshot protections: features to prevent screenshots.
- No Forwarding: Messages cannot be forwarded from a Secret Chat.
- Self-Destruct Timers: You can set messages to automatically delete after being read, from 1 second to 1 week.
Remember, Secret Chats are device-specific. A Secret Chat started on your phone will not appear on your desktop app.
Essential Privacy Settings
Secret Chats alone won’t keep you fully private. Other details, like who you message and when you’re active, can still give you away. To stay safe, make sure to adjust your main privacy settings.
- Forwarded Messages: When someone forwards a message you sent, it can link back to your account.
Set “Who can add a link to my account when forwarding my messages” to “Nobody”. This anonymizes your forwarded messages.
- Calls: Who can call you via Telegram.
Set to “My Contacts” to block unsolicited voice/video calls.
- Two-Step Verification (2FA): This is critical.
It adds a password to your account, protecting it even if someone intercepts your SMS login code. Enable it under Settings > Privacy and Security > Two-Step Verification.

What Does Telegram’s Privacy Policy Say
Many users never read the Telegram privacy policy. While privacy policies can be lengthy, they explain how data is collected and used.
Telegram’s privacy policy states it only collects the essential information needed to run its service and does not use your data for ads. The data collected includes:
- Basic Account Data: Your phone number, profile name, and profile picture.
- Contact Information: If you sync contacts, Telegram uses hashed versions to find friends on the platform.
- Cloud Chat Data: Your messages, media, and files from non-Secret Chats are stored encrypted on Telegram servers.
- Connection and Usage Data: IP addresses, device info, and interaction logs.
Telegram’s policies are simpler than those of major social media companies. However, for Cloud Chats, Telegram controls the encryption keys and can be legally forced to share user data. In contrast, Secret Chats remain private and cannot be accessed.
Are Telegram Links Safe
Official Telegram links (starting with t.me/) are generally safe to click, as they simply redirect to legitimate Telegram profiles, channels, or chats. However, sharing information in these chats can be dangerous because the platform is full of scammers and harmful bots.
Before clicking a Telegram link, consider:
- Who shared it.
- Whether the source is trustworthy.
- What permissions the group requests.
Basic caution can prevent many security issues.
Additional Tips to Improve Telegram Privacy
Beyond Secret Chats, consider these best practices:
- Regularly Review Active Sessions: Check which devices are connected to your account. Remove unfamiliar devices immediately.
- Use Strong Passwords: Avoid simple passwords that can be guessed.
- Keep Telegram Updated: Security improvements are frequently released.
- Enable Screen Locks: Protect access to your device itself.
- Avoid Public Wi-Fi for Sensitive Conversations: Unsecured networks create additional risks.
FAQ for Telegram privacy
Q: If my Cloud Chats are stored on Telegram’s servers, can employees or hackers read them?
A: In theory, Telegram employees with access to the decryption keys could read Cloud Chat content. For hackers, breaching the encrypted storage is highly difficult, but not impossible.
Q: Are Telegram groups end-to-end encrypted?
A: No. Group chats do not use Secret Chat technology and are not end-to-end encrypted.
Q: Does deleting a chat improve privacy?
A: Deleting a chat removes local access, but privacy protection depends on the type of chat and how it was configured.
Q: Can I make my existing chats Secret Chats?
A: No. Secret Chats are separate, new chat sessions. You cannot convert an existing Cloud Chat into a Secret Chat.
Final Thoughts
Telegram remains one of the most powerful messaging platforms available today, offering an excellent balance of speed, flexibility, and customization. However, one of the biggest misconceptions about the app is that all conversations are automatically protected with end-to-end encryption.
The truth is that regular Telegram chats prioritize convenience and cloud synchronization, while Secret Chats provide the highest level of privacy.
In my opinion, Telegram offers excellent privacy tools, but users need to actively configure them. Simply installing the app is not enough. By reviewing your Telegram privacy settings, enabling two-step verification, being cautious with Telegram links, and using Secret Chats when necessary, you can enjoy a much safer and more private messaging experience.
