BatChat vs Telegram: A Complete Privacy and Security Comparison

Choosing the right encrypted messaging app matters more than ever. With surveillance concerns growing and data breaches making headlines weekly, the app you use daily shapes your digital privacy in ways most people overlook. BatChat vs Telegram is one of the more interesting comparisons in the secure messaging space right now. Telegram has built a massive user base over the past decade, while BatChat has emerged as a privacy-first alternative that takes a fundamentally different approach to protecting conversations. We’ve spent considerable time using both apps across multiple devices, and this breakdown covers everything from encryption protocols to everyday usability.

That table tells the basic story, but the details underneath are far more nuanced. Let’s break down what each of these differences actually means in practice.

Encryption: Where the Two Apps Fundamentally Differ

Encryption is the single biggest difference between BatChat and Telegram, and it’s not even close. This distinction alone could determine which app deserves a spot on your phone.

BatChat’s Approach: E2EE Everywhere

BatChat encrypts every single conversation by default. Not just “secret” chats or opt-in modes — every message, every file, every voice note you send gets encrypted before it leaves your device. The app uses RSA-4096 for key exchange paired with AES-256 for symmetric encryption. That’s a serious combination. RSA-4096 means the keys used to establish your encrypted session are significantly harder to crack than the 2048-bit standard most apps settle for. AES-256 is the same cipher the U.S. government uses for classified information.

We tested this by monitoring network traffic during message transmission. The packets leaving the device showed nothing readable — no message content, no metadata linking sender to recipient beyond what’s needed for routing. This is how encrypted messaging should work: private by default, no toggles required.

Telegram’s Approach: Optional and Limited

Telegram handles encryption differently depending on the type of chat. Regular one-on-one chats and group chats use client-server encryption. Your data gets encrypted while traveling between your device and Telegram’s servers, but Telegram can read the content once it arrives. The company has stated they would only comply with legal requests for data that passes through their servers.

Telegram does offer “Secret Chats” with end-to-end encryption using their custom MTProto 2.0 protocol. These chats support self-destructing messages and are device-specific — they don’t sync across your other devices. The problem? You have to manually enable Secret Chats for each conversation. Most Telegram users don’t even know this feature exists, and it’s only available for one-on-one chats. Group conversations never get end-to-end encryption on Telegram.

The EFF’s encrypted messaging guide consistently highlights the importance of default E2EE. When encryption is optional, human behavior takes over — people forget, people get lazy, and conversations that should be private end up readable by the platform hosting them.

What This Means for You

If privacy is the reason you’re looking at either of these apps, BatChat has a clear structural advantage. There’s no risk of forgetting to enable encryption because it’s baked into every interaction. With Telegram, you need to consciously switch to Secret Chats every single time, and even then, the feature doesn’t work for groups or multi-device scenarios.

Privacy Features Beyond Encryption

Encryption handles the content of your messages, but privacy extends further. What data does the app collect about you? How does it handle your identity? Can someone take a screenshot of your conversation?

Account Registration and Identity

Telegram requires a phone number to create an account. That phone number is visible to anyone who has it saved in their contacts. You can hide it from non-contacts, but the fact remains: Telegram knows your real phone number from the moment you sign up. For users in countries with authoritarian governments or those who simply prefer not to link their real identity to their messaging app, this is a meaningful limitation.

BatChat takes a different approach. You don’t need a phone number to register. The app generates a unique identifier — similar to how Signal handles registration. This means you can use the app without revealing your real phone number to anyone, including the service itself. If you want more details on how this works, our step-by-step registration guide walks through the entire setup process.

Screenshot and Screen Recording Protection

This is a feature that sounds minor until you actually need it. BatChat blocks screenshots and screen recordings within the app. If someone tries to capture your conversation on their device, they get a blank screen or an error notification. For anyone sharing sensitive information — business discussions, personal matters, anything you don’t want forwarded — this matters more than you’d expect.

Telegram doesn’t offer screenshot protection. Anyone in a chat can take a screenshot and share it however they want. Telegram’s approach has always been to trust the other person, which is fine for casual conversations but less than ideal when you need actual control over your content.

Data Collection and Transparency

Telegram stores your chats on their servers indefinitely. You can manually delete them, and they offer a “auto-delete” feature, but the default is permanent storage on their infrastructure. Telegram is also based in Dubai, which has its own set of data retention and surveillance regulations.

BatChat minimizes server-side data storage. Since all messages are end-to-end encrypted, the servers only store encrypted blobs that are unreadable without the recipient’s device keys. The company’s privacy policy explicitly states that message content cannot be accessed by BatChat staff or third parties. This is an important distinction — encryption that the server operator can’t bypass is fundamentally more trustworthy than encryption where the server holds the keys.

Features and Functionality

Privacy isn’t the only consideration. A messaging app needs to be functional enough for daily use. Here’s how the two compare on features that matter during regular use.

Group Chats and Channels

Both apps support massive group sizes — up to 200,000 members. In practice, neither app is commonly used at that scale for traditional group conversations, but the headroom is there.

Telegram’s group features are more mature. Admins get fine-grained controls over member permissions, slow mode, discussion groups linked to channels, and extensive bot integration. Telegram channels function as broadcast tools that can reach millions of subscribers. This is one area where Telegram’s larger user base and longer development history show.

BatChat supports large groups and has been steadily improving its admin tools. You’ll find standard features like member management, message deletion, and admin roles. If you’re running a community with complex permission needs, Telegram currently offers more flexibility. For most group chat use cases — family groups, small teams, friend circles — BatChat handles everything you’d need.

File Sharing and Media

Telegram wins on raw file size limits. Free accounts support up to 2 GB per file, and Premium users get 4 GB. Telegram’s cloud storage model means files are accessible from any device without forwarding them to yourself. This makes it popular as a cloud storage substitute for many users.

BatChat supports up to 2 GB per file, which covers the vast majority of everyday sharing needs. The tradeoff is that files sent through BatChat’s end-to-end encrypted channels don’t get stored on a central server you can browse from any device. You download them directly from the sender. It’s a conscious privacy decision — convenience vs. control.

Voice and Video Calls

Both apps support voice and video calling. Telegram’s call quality has been reliable in our testing, with quick connection times and adaptive bitrate. They also offer group video calls with screen sharing, which is useful for work scenarios.

BatChat’s calling features are end-to-end encrypted by default, consistent with their approach to everything else. Call quality has been solid in our experience, though the feature set is more straightforward — voice and one-on-one video calls. Group video calling and screen sharing features are still being developed.

Customization and Stickers

Telegram is famous for its sticker ecosystem. Custom sticker packs, animated stickers, emoji sets, and interactive elements make the app feel lively. You can spend hours browsing community-created sticker packs. The customization extends to chat themes, custom backgrounds, and a range of UI tweaks.

BatChat offers basic customization — chat themes, reaction emojis, and standard sticker support. It’s functional but doesn’t compete with Telegram’s depth here. If sticker packs and chat aesthetics are a priority, Telegram has the upper hand.

Platform Availability and Performance

Telegram runs on virtually everything: Android, iOS, Windows, macOS, Linux, and a full-featured web client. The web app is particularly convenient when you need to send a quick message from a shared or work computer without installing anything.

BatChat supports Windows, macOS, Linux, Android, and iOS. There’s no web client at this point, which means you need to install the app on each device. The desktop app for Windows performs well — messages sync quickly and resource usage stays reasonable. If you want to try it, you can download BatChat for Windows directly.

User Experience and Setup

Telegram’s setup is straightforward: enter your phone number, receive a code, and you’re in. The onboarding process takes about two minutes. The interface is polished and familiar to anyone who’s used a modern chat app. Telegram’s massive user base also means most of your contacts are probably already there.

BatChat’s registration takes slightly longer since it generates a unique identifier rather than relying on a phone number. The interface is clean and intuitive, though the design language leans more utilitarian than Telegram’s vibrant aesthetic. Performance has been smooth in our testing — messages deliver in 1-2 seconds, media loads quickly, and the app remains responsive even in large group chats.

The real question with user experience is network effects. Telegram has over 800 million active users. Your friends, family, and colleagues are more likely to already be on Telegram. BatChat is still building its user base, which means you may need to actively recruit people to your contacts. That said, if the people you communicate with most also care about privacy, the switch isn’t difficult.

Security Track Record

Both apps have had their security scrutinized by researchers, though with different outcomes.

Telegram’s MTProto protocol has faced criticism from cryptographers. A 2020 analysis by researchers from MIT and others raised concerns about the protocol’s design choices. Telegram has addressed some of these concerns in subsequent updates, but the fact that it uses a custom protocol rather than a well-established, peer-reviewed one remains a point of discussion in the security community.

BatChat uses established cryptographic primitives — RSA and AES — which have been extensively studied and are considered secure by the broader cryptographic community. While BatChat’s implementation hasn’t undergone the same level of third-party audit as apps like Signal, the choice of well-understood algorithms provides a solid foundation.

Pricing

Both apps are free to use. Telegram offers a Premium subscription ($3.99/month) that unlocks faster downloads, larger file uploads, more stickers, and exclusive features. BatChat is entirely free with no premium tier. All features, including end-to-end encryption, are available to every user without payment.

So Which One Should You Use?

The answer depends on what you value most in a messaging app.

Choose BatChat if:

End-to-end encryption by default is non-negotiable for you
You want to register without providing a phone number
Screenshot protection matters for your use case
You prefer that your message content stays private from the platform itself
You’re communicating sensitive information regularly

Choose Telegram if:

You need group video calls and screen sharing for work
File storage and cloud-synced media are important to you
You value a massive sticker collection and deep customization
Most of your contacts are already on Telegram and won’t switch
You want a web client for quick access from any browser

Frequently Asked Questions

Is Telegram really end-to-end encrypted?

Not by default. Regular Telegram chats use client-server encryption, meaning Telegram’s servers can access your message content. End-to-end encryption is only available through “Secret Chats,” which you must manually start for each conversation. Secret Chats don’t sync across devices and only work for one-on-one conversations — group chats never get E2EE on Telegram.

Can I use BatChat without a phone number?

Yes. BatChat generates a unique anonymous identifier during registration. You don’t need to provide a phone number, email address, or any other personally identifiable information to create an account and start messaging.

Which app is better for large group chats?

Both apps support up to 200,000 members in a group. Telegram has more mature admin tools, including fine-grained permissions, slow mode, and bot integration. BatChat’s group features cover standard use cases well but don’t yet match Telegram’s depth for community management. For most users with groups under a few hundred members, either app works fine.

Does BatChat have a web version like Telegram?

No, BatChat currently doesn’t offer a web client. You need to install the native app on your devices (Windows, macOS, Linux, Android, or iOS). Telegram’s web app is a notable convenience advantage for users who frequently switch between shared or borrowed computers.

How does file sharing compare between BatChat and Telegram?

Telegram supports files up to 2 GB for free users and 4 GB for Premium subscribers, with cloud storage that makes files accessible from any device. BatChat supports up to 2 GB per file, but files are sent peer-to-peer through encrypted channels rather than stored on central servers. Both limits handle the vast majority of everyday sharing needs — documents, photos, and short videos.

Is BatChat safer than Telegram for sensitive conversations?

For conversations where you need strong privacy guarantees — legal discussions, business negotiations, personal matters — BatChat’s default end-to-end encryption, anonymous registration, and screenshot protection provide stronger safeguards than Telegram’s opt-in approach. The fact that BatChat’s servers can’t read your messages at all, combined with no phone number requirement, creates a more private environment by design.
