Voice calls, video calls, group chats, stickers, social channels, self-destructing chats, end-to-end encryption, lots of spam, and targeted ads. Viber provides all the greatest hits of the messaging app world. It’s like a mix of WhatsApp and Telegram with a dash of Snapchat thrown in for good measure. And it’s huge - with over a billion users around the world. During the pandemic, Viber expanded it’s group video chat features to allow for more users, which resulted in cool things like teachers in Hungary using it to help stay in touch with their students. Good vibes indeed.

What could happen if something goes wrong

Viber seems to do a fairly good job at protecting their users' privacy and security. Especially when compared to other similar messaging apps like Telegram and Whatsapp. It's not perfect, but we do like they've been using end-to-end encryption by default since 2016 (except for group calls, those are only encrypted in transit). Some other good thing they do: Once a message is delivered, it is deleted from their servers so your messages aren’t sitting around where others could potentially access them and you can choose to hide yourself from any of the contacts in your contact list (handy when it comes to that ex of yours!). Some things they do we don’t love: When you join a group, your phone number will be visible to all group members, which could be a lot of people, so be careful. Also, Viber has had problems with bad people sending lots of spam and viruses. As always, it’s good to be careful reading or downloading things from people you don’t know. And it's been reported about 20% of Viber’s revenue comes from ads. They collect users’ IP-address location, gender, and age to target these ads, although users can opt out of gender and age targeting if they take the time to change their settings. Their ad partners may also combine the data collected about you when using Viber with their outside records to do even more targeting. So lock those settings down as much as you can! One thing we really loved about Viber is in 2020 they joined the #StopHateForProfit campaign (Mozilla did too!) and cut all business ties with Facebook. Gotta love a company that takes a stand against hate, misinformation, and unethical privacy practices!

What data does it collect?

How does it use this data?

Viber uses Cookies & Tracking Technologies by advertisers (including Google, Twitter, Adjust, Russian Yandex and VK, etc.). As such, they enable targeted ads on its own Viber app, but also allow numerous third parties combine information they collect from Viber with other information they have independently collected relating to your web browser’s activities across their network of websites. The information Viber collects may be combined with information from outside records (e.g. demographic information and additional contact information) that they "have received in accordance with the law." When you join Viber, the contacts in your address book that are already Viber members may be informed that you're now on Viber too.

Artificial Intelligence

Does the product use AI?


Does the AI use your personal data to make decisions about you?

Can’t Determine

Does the company allow users to see how the AI works?


Viber uses several AI and machine learning systems in their backend systems for things like spam detection, community moderation, language translation and others. Viber claims that sharing the algorithm for spam detection, community moderation, language translation etc. publicly will actually defeat their purpose (for example spammers will know how to bypass their systems and attack users).
