Telegram vs Signal: Which Is Safer for Indian Users?

I read a viral tweet last week claiming Telegram is "just as secure as Signal" and I just... no. That's not how any of this works. I've been testing both apps for years, I've dug through their documentation, I've sat through conference talks by cryptographers who audit this stuff — and the two apps aren't even playing the same sport. One's a privacy tool. The other's a feature-packed social platform that sometimes does encryption if you ask nicely.

So let's do this differently. No giant walls of text. No marketing bullet points. I'm going to answer the questions my friends, family, and readers in India keep throwing at me, one by one, as honestly as I can. Think of this as a long chai-fueled conversation — grab your cup.

---

Q: Wait, aren't both Telegram and Signal "encrypted" apps? What's the actual difference?

A: This is where the confusion starts, and honestly, I think Telegram's marketing deserves a lot of blame for it.

Signal encrypts every single thing you do on the app — messages, voice calls, video calls, group chats, file transfers — using end-to-end encryption (E2EE) by default. You don't toggle anything on. You don't pick a special chat mode. The moment you open a conversation, nobody except you and the person you're talking to can read it. Not Signal's servers, not Signal's employees, not a hacker who breaks into their data center. Nobody. They use something called the Signal Protocol, and it's probably the most scrutinized, peer-reviewed encryption standard in the messaging world right now.

Telegram? Regular chats — which is what 99% of Telegram users actually use — are not end-to-end encrypted. They're encrypted between your phone and Telegram's servers (that's called client-server encryption or encryption in transit), but Telegram's servers can absolutely read those messages. They sit there, in plaintext form on Telegram's infrastructure. The company could read them if it wanted to. A rogue employee could access them. A government with a court order could demand them.

Telegram does have a feature called "Secret Chats" that offers E2EE. But here's the catch — you have to manually start a Secret Chat each time. It only works for one-on-one conversations. It doesn't work on desktop. And group chats? Never end-to-end encrypted. Not ever. If you're in a Telegram group with 500 people discussing anything sensitive, Telegram's servers can see every word.

So when someone says "both are encrypted," yeah, technically true in the way that a bicycle and a fighter jet are both "vehicles." The difference in what that encryption actually protects you from is enormous.

Q: I've heard Telegram uses its own encryption protocol. Is that a problem?

A: It might be. Telegram uses a homegrown protocol called MTProto (currently on version 2.0). Now, there's nothing necessarily wrong with building your own crypto — but the security community generally gets nervous when companies do this instead of using well-tested, publicly audited standards.

The Signal Protocol has been formally verified by academic cryptographers. Multiple independent research teams have examined it. WhatsApp, Google Messages, Facebook Messenger's encrypted mode, and Skype's private conversations all use it. That's a massive attack surface — if there were a flaw, someone would've probably found it by now.

MTProto has had some academic scrutiny, and researchers have flagged concerns over the years. In 2021, a team from ETH Zurich and Royal Holloway found theoretical weaknesses — not catastrophic ones, but the kind of things that make cryptographers wince. Telegram fixed those specific issues, to be fair. But the broader point stands: MTProto hasn't been battle-tested the way the Signal Protocol has, and Telegram's server-side code is completely closed source. We're sort of taking their word for it that the implementation matches the specification.

Does this mean MTProto is broken? No. I wouldn't go that far. But if I had to bet my personal safety on one protocol versus the other, I'd pick the Signal Protocol without a second thought.

Q: What about open source? Both apps claim to be open source, right?

A: This is another area where the details matter more than the headline.

Signal is fully open source — client apps AND server code. You can go to GitHub right now and read every line. Independent researchers regularly audit it. The code that runs on your phone is verifiable against what's published. There are reproducible builds, meaning you can compile the source yourself and confirm it matches the app on the Play Store or App Store.

Telegram publishes its client-side code, so the apps on your phone are technically open source. But the server code — the stuff that actually handles your messages, stores your data, manages encryption keys for regular chats — that's completely proprietary. Nobody outside Telegram knows exactly what's running on their servers. And since regular Telegram chats rely on server-side processing (remember, they're not E2E encrypted), the server code is arguably the most important part to audit.

It's a bit like a restaurant letting you inspect the dining room but keeping the kitchen locked. Sure, the tables look clean. But what's happening behind that door?

Q: How much of my data does each app collect?

A: This one isn't even close.

Signal collects almost nothing. Seriously, it's borderline absurd how little they store. Your phone number. The date you registered. The last time you connected to their servers. That's it. When the FBI served Signal with a grand jury subpoena back in 2021, the company responded with a filing that basically said: "Here's the phone number, here's two timestamps, and that's literally everything we have." They couldn't hand over message content, contact lists, group memberships, or anything else because they don't have it.

Telegram stores a lot more. Your messages (for non-Secret Chats), your contact list, your IP address, device information, usernames of people you interact with, files you share, group memberships, and metadata about your activity patterns. Pavel Durov, Telegram's founder, has repeatedly said the company doesn't share data with governments and has a track record of resisting pressure — they left Russia rather than hand over encryption keys in 2018. I respect that stance. But the data still exists on their servers, which means it's a target. A breach, a subpoena in a more cooperative jurisdiction, or a change in company policy could expose it.

I should note — Durov was arrested in France in August 2024, and while the charges were related to content moderation rather than encryption, it raised real questions about what happens to Telegram's defiance when its leadership faces personal legal consequences. That situation is still unfolding as of early 2026, and it's something I'd keep an eye on.

Q: Where are their servers located? Does that matter for Indian users?

A: Signal's servers are primarily in the United States, operated by the Signal Foundation (a nonprofit based in California). Telegram's infrastructure is more distributed — they've operated from various locations including the UAE, and their server locations aren't fully disclosed publicly.

For Indian users, server location matters in a couple of ways. India's IT Act and the 2021 IT Rules give the government authority to demand information from intermediaries operating in India. Both Signal and Telegram have to comply with Indian law to some extent if they want to remain available here.

But here's where the technical architecture makes a difference. Even if the Indian government sends Signal a legal demand for user data, Signal can't hand over message content because they don't possess it. Their architecture makes compliance with content demands technically impossible. Telegram, on the other hand, could technically comply with data demands for regular chat content, because that data sits on their servers in readable form.

The 2021 IT Rules also require messaging platforms to identify the "first originator" of flagged messages — that means breaking anonymity for viral content. This requirement is basically incompatible with Signal's design. For Telegram's regular chats, it's at least theoretically possible since messages flow through their servers in accessible form.

Will either app actually get banned in India? Hard to say with certainty. Telegram has been temporarily restricted or banned in several countries, including Brazil, Iran, and parts of China. Signal's smaller footprint and nonprofit status probably make it a lower-priority target for regulators, but that's a guess on my part.

Q: Okay, but Telegram has way better features. Doesn't that count for something?

A: Absolutely. I won't pretend otherwise — Telegram is a significantly more feature-rich app. Let me be honest about the comparison here:

Group chats: Telegram groups can hold up to 200,000 members. That's a small city. Signal recently bumped its limit to about 1,000, which is a big improvement from the old 150-person cap, but it's still a fraction of what Telegram offers.

Channels: Telegram's broadcast channels are genuinely useful — news outlets, creators, and organizations use them to push updates to unlimited subscribers. Signal has nothing comparable. They added a Stories-like feature, but it's not the same thing.

File sharing: Telegram lets you send files up to 4 GB (they bumped it from 2 GB for Premium users). Signal's limit is around 100 MB. If you're sharing large videos or documents, Telegram wins by a landslide.

Bots and integrations: Telegram's bot ecosystem is massive. You can build payment systems, polls, games, automated workflows — there's an entire developer platform around it. Signal has no bot support and likely won't add it, because bots would require server-side message processing that conflicts with their E2E encryption model.

Stickers and customization: Telegram has an enormous library of sticker packs, custom themes, animated emoji, and chat folders. Signal is comparatively bare-bones. It's gotten better — they added sticker packs and some customization options — but it's not trying to compete with Telegram on pizzazz.

Disappearing messages: Both apps support them. Signal gives you more granular control — you can set timers from 30 seconds to 4 weeks, and you can make disappearing messages the default for all new chats. Telegram's implementation is solid but slightly less flexible.

Username system: Telegram has long let you communicate via usernames without revealing your phone number. Signal added a similar feature in 2024, which was a welcome change. On both apps, you can now chat without sharing your number, though Signal's implementation is still newer.

So yeah — if features are your priority, Telegram wins hands down. The question is whether those features are worth the privacy trade-offs. For a lot of people, they are. For some conversations, they shouldn't be.

Q: What about usability? I'm not a tech person — which one is easier to use?

A: Honestly, both are pretty straightforward. If you've used WhatsApp, you can pick up either one without much trouble.

Telegram feels more polished in some ways — the app is snappy, the interface is well-designed, syncing across devices is effortless (you can use it on your phone, tablet, laptop, and web browser simultaneously, and everything stays in sync). That's because messages are stored on Telegram's cloud servers, which is convenient but, as we discussed, means less privacy.

Signal is a bit more bare-bones in its interface. Multi-device support has improved — you can link up to five devices now — but there's a slight delay sometimes when syncing message history to a new device. It also can't do web-based access the way Telegram does, because the encryption architecture makes that harder to implement securely.

One thing I'll say: Telegram's onboarding is smoother for non-technical users. It automatically backs up your chats to the cloud, imports your contacts, and suggests channels and groups based on your interests. Signal asks for your phone number and... that's about it. There's no discovery, no suggested content, no social features. It's deliberately minimal. Some people love that. Others find it isolating.

For Indian users specifically, both apps support Hindi and several other Indian languages in their interface. Telegram probably has a slight edge in localization since it's more widely used here.

Q: A friend told me Telegram was founded by someone who stood up to Putin. Doesn't that make it trustworthy?

A: I hear this a lot, and it's worth addressing properly. Pavel Durov, who co-founded VKontakte (Russia's biggest social network) before starting Telegram, did leave Russia after the government pressured him to hand over user data from VK. He refused, lost control of his company, and eventually left the country. That took real conviction, and I respect it.

But personal courage doesn't equal technical security. Durov's willingness to resist government pressure is admirable — but the architecture of Telegram still gives the company access to most user messages. Trust in the person running the service is a much weaker guarantee than a system designed so that trust isn't required in the first place.

Signal's approach is different philosophically. Moxie Marlinspike (who founded Signal) and the current Signal Foundation leadership have built a system where you don't need to trust them. Even if Signal were taken over tomorrow by the most corrupt organization imaginable, your existing encrypted messages would still be unreadable to them. The math doesn't care who's running the servers.

There's something to be said for that. People change, companies get acquired, founders get arrested. Systems that rely on the goodwill of specific individuals are fragile. Systems that rely on mathematics are not.

Q: What about the money? How do these apps sustain themselves, and does that affect my privacy?

A: Great question, and one that people don't ask often enough.

Signal is run by the Signal Foundation, a 501(c)(3) nonprofit. It's funded primarily by donations and a $50 million initial grant from WhatsApp co-founder Brian Acton (who left Meta over privacy disagreements). Signal doesn't run ads, doesn't sell data, and doesn't have investors demanding quarterly growth. Their incentive structure is about as clean as you'll find in tech. Could funding dry up someday? Maybe. But for now, the model works.

Telegram launched Telegram Premium in 2022 — a paid subscription that gives users faster downloads, larger file uploads, exclusive stickers, and other perks. They've also started running ads in large public channels. In December 2023, Telegram reported having over 900 million monthly active users globally. With Premium subscriptions and advertising revenue, Durov claims the company is approaching profitability.

Here's my concern: when a company starts monetizing through ads, there's always an incentive to collect more data about users to make those ads more targeted. Telegram currently says its ads are based on channel topics, not individual user data. I'll take them at their word for now. But ad-driven business models have a gravitational pull toward surveillance, and I've seen it play out too many times to be fully comfortable.

Q: So what should I actually use? Just tell me straight.

A: It depends on what you're doing, and I know that's an annoying answer, but hear me out.

Use Signal for:

• Private conversations you wouldn't want anyone else reading — with family, friends, partners, doctors, lawyers, journalists, anyone
• Discussions about finances, health, legal matters, or anything personal
• Activism or journalism, especially if you're covering sensitive topics in India
• Any situation where you'd be uncomfortable if a stranger read the conversation

Use Telegram for:

• Large community groups and public discussions
• Following news channels and content creators
• Sharing large files
• Casual conversations where the content isn't particularly sensitive
• Situations where you need bot integrations or automation

If you're going to use Telegram for anything private, at minimum use Secret Chats for one-on-one conversations. Enable the self-destruct timer. Don't assume that regular Telegram chats are private just because the app has a lock icon in its branding.

And look — I think most people will end up using both. That's fine. I do. I have Signal for close friends and sensitive conversations, and I'm in a handful of Telegram groups for tech news and community stuff. The key is understanding which tool is appropriate for which situation.

Q: One last thing — could you be wrong about any of this?

A: Absolutely. Security is a moving target. Telegram could announce default E2EE tomorrow, and this entire article would need rewriting. Signal could suffer a catastrophic breach that changes everything we think about its architecture. MTProto could get a rigorous independent audit that puts all concerns to rest. I've been following this space long enough to know that today's consensus can become tomorrow's outdated take.

What I've shared here reflects the state of things as of early 2026, based on publicly available documentation, independent audits, and my own testing. I've tried to be fair to both apps — they're both better than SMS, both better than unencrypted email, and both created by people who seem to genuinely care about user freedom on some level.

But if someone tells you Telegram and Signal are "basically the same" on privacy? Push back on that. The architecture is different, the defaults are different, and the data that exists on their servers is different. Those differences matter — especially in a country where digital surveillance capabilities are expanding and data protection laws are still catching up.

Stay skeptical. Ask questions. And maybe keep Signal installed, even if you only use it for the conversations that really count.
