Is Telegram App Safe? What You Should Know Now
By Ellis Blackwood · Subproject Zero
Stop assuming your conversations are private by default. You open an app, you type your words, and a silent promise forms in your mind: this is for your eyes only, or for the eyes of the one you send it to. But this assumption, you will find, is rarely earned.
You believe your messages are secure. You trust in the unspoken agreement of digital walls. That trust is often misplaced.
En bref
Telegram offers a nuanced approach to security. While 'Secret Chats' provide end-to-end encryption for one-on-one conversations, standard cloud chats, groups, and channels use client-server encryption. A significant policy change in 2024 means Telegram now shares user IP addresses and phone numbers with authorities under specific conditions, challenging the app's long-held reputation for absolute privacy.
Is Telegram App Safe?
Telegram’s safety depends entirely on how you use it and what you understand about its underlying design. It is not universally 'safe' in the way many users perceive it. Standard conversations, groups, and channels operate differently from the 'Secret Chats' that offer stronger protection.
What Happens to Your Standard Chats?
When you send a message in a standard individual chat, a group, or a channel on Telegram, your words are not truly end-to-end encrypted by default. Instead, they use client-server encryption. This means your message is encrypted on your device before it travels to Telegram’s servers. Once there, it is decrypted and then re-encrypted for storage on their cloud. This process allows your chat history to sync across all your devices, a convenience that comes with a trade-off.
You can access your entire history from any phone, tablet, or computer where you are logged in. This is possible because Telegram’s servers hold a readable copy of your messages. The company states they use a distributed infrastructure, storing data in multiple data centers across different jurisdictions, with decryption keys split and stored separately. This makes it harder for any single entity to access your data, but it does not mean your messages are inaccessible to Telegram itself. They retain the capability.
The Promise of Secret Chats
If you seek genuine end-to-end encryption on Telegram, you must manually initiate a 'Secret Chat'. In these specific conversations, only the sender and recipient hold the decryption keys. Your messages are not stored on Telegram’s servers. They are device-specific, meaning they will not sync across your other devices. You cannot forward messages from a Secret Chat, and you gain features like self-destructing messages and notifications if the other person attempts a screenshot. This is the closest Telegram comes to the private communication many believe the entire app offers.
What Telegram Collects, Even in Secret
Even when you use 'Secret Chats', Telegram still collects metadata. They store your phone number, your IP address, and your contacts. You may think your content is safe, but this metadata alone can tell a story. It can reveal who you communicate with, when you do it, and from where. This information can be used to identify patterns, build profiles, or track your movements over time. You leave digital breadcrumbs, even when you believe your path is hidden.
This is where the illusion of comprehensive privacy can break down. The app’s design provides certain protections for message content, but its collection of identifying metadata for all users—even those in Secret Chats—means a full picture of your activity is never truly out of reach.
When Authorities Ask, Telegram Answers
For years, Telegram cultivated a reputation for unyielding resistance to government requests. That changed. In 2024, Telegram updated its privacy policy. You need to know this. The company now states it may share your IP address and phone number with authorities in response to valid judicial orders for specific criminal investigations. These include serious cases such as cybercrime, drug trafficking, and child exploitation. Before this policy shift, such disclosures were primarily limited to terrorism cases, with a historically low number of fulfilled requests.
The scope of shared data is specific: your IP and phone number, not the content of your end-to-end encrypted 'Secret Chats'. But for standard cloud chats, where content is on their servers, the potential for wider disclosure is inherent in the design. You are no longer navigating an absolutes landscape; the lines have blurred.
The Leak You Did Not See
Beyond official policies, external threats loom. You might recall the reports from 2024. A massive archive, 122 GB in size, containing leaked login credentials—emails and passwords—was found circulating across hundreds of Telegram channels. This was not a breach of Telegram's encryption itself, but a widespread distribution of user data harvested from other sources, then shared freely within the app. It reminds you that your security is only as strong as your weakest link, and often, that link exists outside the app's direct control but within its ecosystem.
What You Can Do
- Enable Two-Factor Authentication (2FA). This adds an essential layer of security to your account. Go to Settings > Privacy and Security > Two-Step Verification (Cloud Password) and set a strong, unique password. This prevents unauthorized access even if your primary password is compromised.
- Use Strong, Unique Passwords. Ensure the password for your Telegram account is complex and not reused on other services. A password manager can help you generate and store these.
- Opt for 'Secret Chats' for Sensitive Conversations. If a conversation requires true end-to-end encryption, start a Secret Chat. Remember, these are device-specific and do not sync. You must initiate them manually for each sensitive one-on-one discussion.
- Be Mindful of Metadata. Understand that even in Secret Chats, Telegram logs your IP address, phone number, and contacts. Adjust your communication habits accordingly if this level of metadata collection is a concern for you.
What to Remember
- Standard Telegram chats are not end-to-end encrypted by default.
- 'Secret Chats' provide true end-to-end encryption but are device-specific.
- Telegram collects metadata like IP addresses and phone numbers from all users.
- Since 2024, Telegram shares IP addresses and phone numbers with authorities for criminal investigations.
- External data leaks, even if not originating from Telegram's core systems, can still impact user security within the app's channels.
These actions can mitigate some risks. They do not, however, address the fundamental issue of data that lives beyond your control, or the metadata that paints a portrait of your digital life for those who wish to see it. A messenger built from the ground up to keep no record of your conversations, designed to truly forget what was said, would operate differently. A messenger that keeps no archive, and where messages are deleted from the server after a fixed 24 hours, changes the equation entirely. You would know that what you send truly disappears.
You make choices about your digital presence every day. Are you truly aware of the records you leave behind?
