In late August 2024, French authorities detained Telegram founder Pavel Durov as part of an investigation into alleged failures to curb illegal activity on the platform. Within weeks, Telegram had quietly changed its privacy policy to say it could hand over user IP addresses and phone numbers to authorities when legally required. For millions of people who assumed Telegram was a private fortress, that was a wake-up call. So when people ask whether Signal or Telegram is safer, the honest answer starts with a question: safer from whom?
The Short Answer Depends on Your Threat Model
Security experts rarely crown a single winner in the Signal vs Telegram debate, because “safe” means different things to different people. A journalist protecting a source from a hostile government has different needs than a family group chat planning a birthday dinner. Still, if you strip away the marketing, one platform is built around privacy as its core purpose, and the other is built around features, speed, and scale. That architectural difference shapes almost everything else.
Here is the blunt version: Signal is safer by design. Telegram is safer than many mainstream apps but weaker than its reputation suggests. The rest of this article explains why, with the caveats that matter.
Encryption: End-to-End by Default vs. Optional
This is the single biggest technical difference between the two apps, and it drives most of the safety conversation.
Signal encrypts every message, call, and group chat with the Signal Protocol, which combines the Double Ratchet algorithm with X3DH key agreement. The protocol has been public since the mid-2010s and is widely regarded as the gold standard for end-to-end encryption. Crucially, it is on by default. You do not have to enable anything, and there is no “normal” mode where messages sit unencrypted on a server. (Which ai is best for coding)
Telegram works differently. Its regular cloud chats and groups are encrypted between your device and Telegram’s servers, but Telegram holds the keys. That means Telegram can technically access the content, and it stores those messages in the cloud so you can sync across devices. True end-to-end encryption on Telegram exists only in Secret Chats, which are one-on-one, device-specific, and must be started manually. Group chats do not get end-to-end encryption at all. (Which option best completes the table title the united nations)
| Feature | Signal | Telegram |
|---|---|---|
| End-to-end encryption | Default for all chats | Only in manual Secret Chats |
| Group chat E2EE | Yes | No |
| Cloud message storage | Minimal | Yes, on Telegram servers |
| Server code open source | Yes | No (clients only) |
| Default disappearing messages | Optional | Optional |
That table alone explains why security researchers tend to favor Signal for sensitive conversations. If you want a broader look at how default settings shape real-world safety, the same principle applies across tech: defaults and business models matter more than feature lists.
Metadata: The Quiet Battleground
Encryption protects what you say. Metadata reveals who you talk to, when, and how often, and it is often more revealing than the content itself. Signal has built its reputation on collecting as little as possible: no contact lists, no social graphs, no message logs. The Signal Foundation, a US nonprofit, has publicly framed privacy as “not an optional mode,” and its design reflects that.
Telegram retains more. Phone numbers, contacts, IP addresses, device information, and cloud chat data all live on its servers. After the September 2024 policy update, Telegram explicitly reserved the right to disclose IP addresses and phone numbers to authorities in response to valid legal requests. That is a reasonable legal posture for a mainstream platform, but it is a meaningfully different privacy stance than Signal’s.
The practical takeaway: if your concern is a determined adversary with legal or technical resources, metadata is where most people get caught, not message content.
Who Runs the App Matters
Ownership and governance shape long-term incentives. Signal is operated by the Signal Foundation, a 501(c)(3) nonprofit founded in 2018, and its client and server code are open source. Telegram is a for-profit company (Telegram FZ-LLC, based in the UAE), and while its client apps are open source, its server code is not fully public. That means independent researchers can inspect Signal’s entire stack but can only partially audit Telegram’s. (Signal (software)))
This is not a knock on Telegram’s engineers. It is simply a structural fact: transparency is easier to verify when the code is open and the organization has no advertising or data-monetization pressure. Signal has also commissioned public independent audits of its protocol and apps over the years, including an influential 2016 NCC Group review of the Signal Protocol. Telegram has had fewer public independent audits of its core protocol.
Features, Convenience, and the Safety Trade-Off
Telegram wins on features, and it is not close. Groups of up to 200,000 members, channels, cloud sync across devices, bots, and slick media handling make it feel like a social network in your pocket. Signal caps group sizes far lower (historically around 1,000) and does not offer cloud backup by default, which frustrates people who switch phones often. (Kindle vs Kobo Paperwhite vs Libra Colour 2026: Which Wins?)
But convenience has a cost. Cloud sync means your messages exist somewhere other than your device. Large public channels mean more surface area for scams, impersonation, and misinformation. None of that makes Telegram “unsafe” in absolute terms; it makes it a different product with a different risk profile. The same trade-off logic shows up in hardware debates: the “best” device depends on what you are optimizing for.
Common Mistakes People Make
Even smart users get this wrong. A few patterns show up again and again.
- Assuming Telegram is fully encrypted. It is not. Regular chats and groups are not end-to-end encrypted, and many users never realize Secret Chats exist.
- Using Secret Chats for groups. You cannot. If your group needs E2EE, Telegram is the wrong tool.
- Ignoring the phone number link. Both apps require a phone number to register, though Signal added usernames in 2024 to reduce number sharing. A burner number is a common but imperfect workaround.
- Believing “disappearing messages” equals anonymity. It reduces exposure but does not hide metadata or prevent screenshots.
- Treating any single app as a silver bullet. Operational security habits matter more than the logo on your home screen.
If you are evaluating tools for family members, especially kids, the same “check the defaults” habit applies. The platform’s design choices, not the marketing, determine real-world safety.
What Actually Works in Practice
For most people, the practical playbook is straightforward. Use Signal for anything you would not want forwarded: health information, legal discussions, source conversations, family finances. Use Telegram for communities, channels, and large groups where convenience matters more than confidentiality. If you must use Telegram for something sensitive, start a Secret Chat, verify the safety number, and set a self-destruct timer.
It also helps to think about your adversary. Protecting a conversation from a nosy coworker is a low bar. Protecting it from a well-resourced state actor is a very high one, and no app fully solves that on its own. Security professionals consistently recommend layered habits: strong device passcodes, timely updates, two-factor authentication, and skepticism toward links from strangers. The same layered thinking appears in AI tool comparisons, where no single tool wins every category and the right choice depends on the job.
The 2024 Shift That Changed the Conversation
Before 2024, Telegram’s privacy reputation rested largely on its founder’s rhetoric and its hands-off moderation stance. The Durov detention in France and the subsequent policy change complicated that story. Telegram now says it may disclose IP addresses and phone numbers to authorities in valid legal cases, and it has reported doing so. Whether you see that as responsible compliance or a privacy retreat depends on your politics, but it is undeniably a shift from the platform’s earlier posture. (Privacy)
Signal, meanwhile, has stayed consistent: minimal data collection, open code, nonprofit governance. Consistency is itself a security feature, because policies that change under pressure are policies you cannot fully rely on.
Conclusion
So, which is safer? Signal is the safer choice for private communication, full stop. It encrypts everything by default, collects almost nothing, publishes its code, and answers to a nonprofit rather than a for-profit company. Telegram is a capable, feature-rich platform that is safer than many alternatives, but its cloud-based model, optional encryption, and evolving legal posture mean it should not be your first pick for sensitive conversations.
The most useful framing is not “which app wins” but “which app fits the job.” Use Signal when confidentiality matters. Use Telegram when community and convenience matter. And in both cases, remember that the app is only one layer of your security. The habits around it, from verifying contacts to keeping devices updated, do most of the real work.
FAQ
Is Telegram end-to-end encrypted by default?
No. Telegram’s regular cloud chats and group chats are encrypted between your device and Telegram’s servers, but Telegram holds the keys and can access the content. True end-to-end encryption is available only in Secret Chats, which are one-on-one and must be started manually. Group chats on Telegram do not get end-to-end encryption.
Does Signal store my messages on its servers?
Signal is designed to retain as little as possible. Messages are end-to-end encrypted, and Signal has stated it does not keep contact lists, social graphs, or message logs. That is a stark contrast with Telegram, which stores regular chat data in the cloud so it can sync across your devices.
Can Telegram hand my data to authorities?
Yes, under certain conditions. Following its September 2024 privacy policy update, Telegram says it may disclose IP addresses and phone numbers to authorities in response to valid legal requests, and it has reported doing so. Signal, by contrast, has very little user data to hand over in the first place.
Is Signal owned by a company that wants my data?
No. Signal is operated by the Signal Foundation, a US 501(c)(3) nonprofit founded in 2018. It has no advertising model and does not sell user data. Telegram is a for-profit company, Telegram FZ-LLC, based in the UAE, and its server code is not fully open source, which limits independent auditing.
Which app is better for large groups and channels?
Telegram, without question. It supports groups of up to 200,000 members, public channels, bots, and rich media features. Signal caps group sizes much lower and does not offer cloud backup by default. The trade-off is that Telegram’s scale and openness create more room for scams and impersonation, so moderation and skepticism matter.
Do I need a phone number to use Signal or Telegram?
Both apps have historically required a phone number to register. Signal added usernames in 2024 to reduce the need to share your number with contacts, which improves privacy. A common workaround on both platforms is registering with a secondary or burner number, though this is imperfect and can complicate account recovery.
The bottom line is that safety is a practice, not a purchase. Neither app will protect you if you click malicious links, reuse weak passwords, or hand your verification code to a stranger. Signal lowers the baseline risk; Telegram raises the ceiling on convenience. Choose deliberately, configure carefully, and revisit your assumptions when policies change, because they do.
