Viber isn’t exactly new to the scene. With over a billion downloads globally, it’s a staple on phones across Europe, Asia, and even pockets of the U.S. What started as a VoIP app has evolved into a full-blown messaging platform—chats, voice calls, video calls, the whole deal.
But here’s the thing: with messaging apps being a prime target for data breaches and surveillance, just being popular isn’t enough. You want to know—is Viber safe? That’s the question we’re getting into. From how it handles your chats to what data it collects behind the scenes, we’ll break it all down.
What Is Viber?
Think of Viber as your all-in-one communication hub. It lets you:
- Send text messages
- Make voice and video calls (one-on-one or in groups)
- Share photos, files, and even stickers (because yes, people still love stickers)
- Create massive group chats
And it’s not picky about where you use it—iOS, Android, Windows, Mac—it’s got you covered. Owned by Japanese company Rakuten, Viber positions itself as a free, secure alternative to bigger names like WhatsApp or Facebook Messenger.
How Secure Are Your Conversations?
Okay, let’s talk about encryption because if your messages aren’t encrypted, they’re basically postcards anyone can read.
Viber uses end-to-end encryption (E2EE) by default. That means your messages, calls, photos—anything you send—is encrypted on your device and only decrypted on the recipient’s. Not even Viber’s servers can peek at them.
They’ve even got their own color-coded lock system (green means secure, gray means something’s off), similar to Signal’s safety numbers. That’s not just for show—it’s there to help users verify their encryption is intact.
Compared to other apps:
- WhatsApp also uses E2EE by default, but is owned by Meta, which raises eyebrows for some.
- Signal is often considered the gold standard for privacy—open-source, super transparent.
- Telegram? Ehh. Its secret chats are encrypted, but regular chats aren’t end-to-end by default.
So, in this arena, Viber holds its own.
Viber’s Data Collection and User Privacy
Now here’s where things get trickier. End-to-end encryption keeps your messages safe, but what about the rest of your data?
Viber does collect some data, including:
- Device information (like your model, OS, and unique identifiers)
- App usage activity (when you’re active, how often you use features)
- Location data (if you allow it)
It also uses this data for things like improving service and showing you ads. Yep—Viber does show ads, though it claims it doesn’t sell your data to third parties. Instead, it uses Rakuten’s ecosystem to serve you “relevant” ads.
On the plus side, users have a fair amount of control over privacy settings:
- You can disable contact syncing.
- Manage whether you want your online status or “seen” timestamp visible.
- Turn off targeted ads.
Is it perfect? Not quite. But it’s not the Wild West either.
Viber’s Privacy and Security Features
Viber offers a few extra tools if you want more control over who sees what—and for how long.
1. Disappearing Messages
You can set a timer (from a few seconds to days) on messages, so they self-destruct after being read. Great for sensitive info or just when you’re feeling a little James Bond.
2. Hidden Chats
These are chats you can hide from your main screen and access only with a PIN. If your phone gets into the wrong hands, they won’t show up unless someone knows exactly where to look—and the PIN to open it.
3. Two-Step Verification
Add an extra layer of security by requiring a code (sent to your number) when signing into your Viber account. Honestly, everyone should turn this on.
4. Spam Protection
Viber automatically detects and blocks spam messages. And it’s pretty good at it—though like any filter, it’s not foolproof. Still, it beats manually deleting sketchy links every day.
Potential Vulnerabilities and Concerns
No app is bulletproof. And yes, Viber has its weak spots.
1. Permissions Creep
Viber asks for access to your contacts, microphone, camera, storage—you name it. Some of that’s necessary (you can’t call without mic access), but still, it’s worth reviewing those permissions regularly.
2. Third-Party Integrations
While Viber isn’t loaded with third-party plugins like some apps, it does allow integrations with services like YouTube, Spotify, and Giphy. That’s fun, but also a potential door for data sharing or misuse. So use them, but wisely.
3. Security Hygiene
At the end of the day, your personal habits matter. If you’re clicking shady links or sharing your PIN, no app can save you. Use common sense, and remember—security is a two-way street.
Viber VS Other Messaging Apps
How does Viber stack up against the competition?
Viber vs. WhatsApp
Encryption: Both offer default end-to-end encryption.
Ownership: WhatsApp is owned by Meta (big data miner). Viber is part of Rakuten.
Data policies: Viber collects less metadata.
Viber vs. Signal
Encryption: Signal is the king here—open-source and community-funded.
Features: Viber has more mainstream features like stickers and built-in calling to landlines.
Transparency: Signal wins on clarity and minimal data collection.
Viber vs. Telegram
Encryption: Telegram’s default chats aren’t end-to-end encrypted. Viber’s are.
Group chats: Telegram supports bigger groups and more bots. Viber keeps things simpler.
Tips for Enhancing Your Viber Security
Even if you trust the app, there’s always room to tighten things up:
- Keep it updated: Old versions = old vulnerabilities.
- Enable two-step verification: Extra hurdle for hackers.
- Use hidden chats: Especially for conversations that need more privacy.
- Think before you click: Don’t open random links or files, even if they’re from a contact.
- Use a VPN: A VPN helps hide your IP address and encrypts your internet traffic—especially useful when you’re on public Wi-Fi or want to keep your location and browsing habits private.
FAQ
1. Is Viber safer than WhatsApp?
Depends on your concern. Viber collects less metadata, but WhatsApp’s security is also strong.
2. Can someone hack my Viber account?
It’s possible—especially if you don’t use two-step verification. But hacks usually result from weak passwords or phishing, not the app itself.
3. Does Viber store my messages?
Nope. With end-to-end encryption, only you and the recipient can see messages. Not even Viber can.
4. Is Viber suitable for business communications?
For casual or internal chats? Sure. But if you’re handling sensitive client data, you might want something more enterprise-grade.
Conclusion
So—should you worry about using Viber?
For the average user? Probably not. It offers solid encryption, decent privacy controls, and some thoughtful security extras. It’s not as minimal as Signal or as slick as Telegram, but it’s balanced.
Still, for users dealing with highly sensitive data or operating in high-risk regions, something like Signal might offer stronger peace of mind.
Viber’s safe enough for most. Just don’t treat it like a vault if you’re working in espionage or investigative journalism.
