Viber - Performance and Accuracy
When Evaluating Viber’s Performance and Accuracy in Privacy Tools
Several key points and limitations come to the forefront.
End-to-End Encryption
Viber employs end-to-end encryption by default for all private and group chats, as well as for audio and video calls. This means that only the sender and the recipient can read or hear the content of the communications, and Viber itself cannot access this data.
Message Deletion and Secret Chats
Viber offers features like the ability to delete messages for both the sender and the recipient, and “Secret Chats” that allow users to set a self-destruct timer for messages. This adds an extra layer of privacy, as these messages are automatically deleted after being read and cannot be forwarded or screenshotted (with some exceptions on iOS devices).
Data Collection and Privacy Policies
Despite the strong encryption, Viber’s data collection practices have raised some concerns. The app gathers user data, including contacts, location data, and device IDs, which is necessary for delivering its services. However, this data collection can lead to worries about potential abuse or improper treatment of private information. Viber’s privacy policies indicate that personal information may be shared for third-party marketing, and there is uncertainty about whether this information is sold or rented to third parties.
Centralized Encryption Scheme
Viber uses a centralized encryption scheme where its servers hold the encryption keys. This has been criticized as a potential vulnerability, as it gives Viber access to users’ private chats, which could be at risk of security breaches or requests for data from authorities.
Transparency and Open Source
Unlike some other secure messaging apps, Viber’s source code is not open to the public. This lack of transparency makes it difficult for independent security assessments and raises questions about the efficacy and openness of Viber’s encryption techniques.
Limitations and Areas for Improvement
Encryption Strength
Some experts argue that Viber’s encryption could be more robust, making user chats susceptible to hacking or eavesdropping.
Data Storage
Viber stores user data on its servers, including phone numbers from the address book, which can be a concern for users prioritizing privacy.
Advertising
Viber allows personalized advertising, which means users may receive messages from brands, potentially compromising their privacy.
Conclusion
In summary, while Viber offers strong end-to-end encryption and useful privacy features like message deletion and secret chats, it has several limitations. These include concerns over data collection, the centralized encryption scheme, and the lack of transparency in its encryption methods. Users need to be aware of these aspects when deciding whether Viber meets their privacy needs.
Viber - Pricing and Plans
Free Viber to Viber Calls
Viber offers free voice and video calls, as well as messaging, to other Viber users. This is made possible through VoIP technology and is available regardless of your location. However, data usage charges may apply, so it’s a good idea to use a Wi-Fi connection to avoid additional mobile data costs.Viber Out Plans
For calls to non-Viber users (e.g., landlines and mobile numbers), Viber offers several plans under its Viber Out service:World Unlimited Plan
- This plan allows you to call any of 60 predetermined countries for an unlimited number of minutes at a fixed monthly price.
Unlimited Country Plan
- This plan lets you call a specific country of your choice for an unlimited number of minutes at a fixed monthly price. This plan is only available for certain countries.
Minutes Country Plan
- This is a prepaid plan that provides a set number of minutes for calling a specific country each month. For example, you might purchase a 120-minute calling plan for the Philippines.
World Credit
- This is a prepaid credit system that can be used to make calls to any country and any type of phone number. You can set up an automatic top-up to ensure you never run out of credit during calls.
Call Rate Calculations
- The cost of a Viber Out call depends on the type of phone number (mobile, landline, special number) and the country you are calling. Calls are charged per minute, and any fraction of a minute is rounded up to the next full minute.
Choosing the Best Plan
The best Viber Out product for you depends on your calling habits. If you regularly call abroad, an Unlimited Country Plan or a Minutes Country Plan is usually more cost-effective than using World Credits. The World Unlimited Plan is particularly beneficial if you need to call multiple countries frequently. In summary, Viber provides a range of options to suit different needs, from free calls between Viber users to various paid plans for calling non-Viber numbers, each with its own set of features and pricing.

Viber - Pros and Cons
When considering Viber as a privacy-focused messaging app, here are some key advantages and disadvantages to be aware of:
Advantages
- End-to-End Encryption: Viber uses end-to-end encryption by default for one-on-one chats, group chats, and one-on-one calls. This means that only the sender and the recipient can read or hear the messages, and not even Viber can access them.
- Message Control: Features like Disappearing Messages allow you to set a self-destruct timer for messages, ensuring they are deleted from all sides of the conversation after being read. You can also edit and delete messages even after they have been seen.
- Hidden Chats: Viber offers the ability to hide chats from your main chat list, accessible only with a PIN. This is useful for keeping sensitive conversations private.
- No Data Selling: Since Viber cannot access your encrypted messages, it cannot sell your private conversations to third parties for advertising purposes.
- Security Updates: Viber promptly updates the app to fix security vulnerabilities and cooperates with external parties to verify patches.
Disadvantages
- Group Call Encryption: While one-on-one calls are end-to-end encrypted, group calls are only encrypted in transit, not end-to-end. This means there is a slight vulnerability in group call security.
- Data Storage: Although messages are deleted from Viber’s servers once delivered, the app still stores phone numbers from your address book on their servers. Additionally, the source code is not open to the public, which can raise trust issues.
- Spam and Viruses: Viber has had issues with spam and viruses, particularly in group chats. Users need to be cautious when interacting with unknown contacts.
- Lack of Password Requirement: Viber does not require a password for login; instead, it uses phone number authentication. However, users can add a security code to their desktop app or enable password-protected secret chats.
- Targeted Ads: Despite strong encryption, Viber is open to advertisers, and users may receive messages from brands and businesses if they have shared their phone number previously.
Overall, Viber offers strong privacy features, particularly with its default end-to-end encryption and message control options. However, it falls short in areas such as group call encryption, data storage transparency, and the presence of spam and targeted ads.

Alternatives and Comparisons
Data Privacy Tools (Non-Communication Apps)
For those looking at broader data privacy solutions beyond communication apps, here are a few alternatives:- Granica AI: This platform focuses on AI-driven data privacy for cloud data lakes and LLM prompts. It offers real-time sensitive data discovery, classification, and masking, which is different from Viber’s communication-centric approach. Granica AI is more suited for enterprises managing large datasets.

- Private AI: This tool specializes in data discovery, masking, anonymization, and replacement for on-premises environments. It uses proprietary de-identification technology but is more focused on data protection in enterprise settings rather than personal communication.
Key Differences
- Scope: Viber is specifically designed for secure personal and group communication, while tools like Granica AI, Securiti AI, and Private AI are focused on broader data privacy and governance for enterprises.
- Features: Viber’s unique features like disappearing messages, hidden-number chats, and the ability to edit or delete seen messages are not typically found in data privacy tools aimed at enterprise data management.
- User Base: Viber is designed for individual users and small groups, whereas the other tools are tailored for large-scale enterprise data management and compliance.
