Plain-English summary
Viber processes highly sensitive biometric data for dating profile verification and collects sensitive information, including religious beliefs, for dating services and AI features. It also collects non-user contact information for Caller ID, potentially revealing their name and spam probability to others. The service also makes inferences about user interests and even income levels based on activity and collected data. Despite these concerns, Viber's core features are secured with end-to-end encryption.

Biometric Data Collection and Use for Verification
Viber processes biometric data, subject to user consent, by comparing a profile photo with a selfie to verify dating profiles and prevent impersonation. The service only keeps a score with the result of this analysis while the dating profile is active.
Why it matters: Your biometric data will be processed when you use dating services to verify your identity, which involves analyzing unique facial features. While only a score is kept, this is a collection of highly sensitive personal information.
**Biometric Data –** to verify that your dating profile is genuine and prevent impersonation, we process biometric data, subject to your consent, by comparing your profile photo with a selfie you provide. This involves analyzing unique facial features to determine whether the same person appears in both images, for which we only keep a score with the result of this analysis while your dating profile is active.
Sensitive Information Processed in Dating Services and AI Features
The service may collect and process sensitive information, including dating preferences and religious beliefs (if provided), as part of registration and usage of dating services. Additionally, use of AI features may involve information that could be considered sensitive and very private if chosen to be provided.
Why it matters: Your sensitive personal data, such as dating preferences, religious beliefs, and private information shared through AI features, may be collected and processed.
In addition, your use of AI features such as summaries, polish messages, instant answers, or other AI in-chat or chatbot features, may also involve information that could be considered sensitive and very private in nature, if you choose to provide it.

Collection and Processing of Non-User Contact Information for Caller ID
The service may add phone numbers and contact names of non-users (if provided by a user) to its Caller ID database for caller identification under Viber Caller ID or Viber In feature. This information can indicate the non-user's name to Caller ID users during calls outside Viber or show a probability of spam.
Why it matters: If you are not a Viber user, your phone number and contact name may be used for Caller ID features, potentially revealing your identity or spam probability to other users when you call them.
**Caller ID**: Your phone number and contact name (if provided to us by a user through sharing their contacts or otherwise) may be added to our Caller ID database and used as part of the caller identification under Viber Caller ID or Viber In feature. Your name can be indicated to Caller ID or Viber In users when you are on a call with them outside Viber or used to show them a probability of spam, if such number has been marked as spam by users. Such process enables Viber to improve our services with the purpose to reduce spam, fraud and harassment for our users.
Viber may process inferences about user interests based on activity within the app and user data. It may also infer income level from general location, travel patterns, device type, and activity within services.
Why it matters: The service may infer your interests and even your income level based on your activity within the app and other collected data.

Use of Non-User Phone Numbers from Address Books
The service may process a mobile phone number even if the individual is not a Viber user, if their number is included in an existing user's address book that has been provided to the service with approval. This is done to show users who in their contacts are already using the services and to allow more efficient communication.
Why it matters: If you are not a Viber user, your phone number may be processed and stored if a Viber user shares their contact list, allowing Viber to identify you as a non-user contact.
**Mobile phone number and contact name, as saved on a Viber user’s phone address book**: We may process your mobile phone number even if you are not a Viber user, in the event that your phone number was included in our existing user’s address book that has been provided to us (and subject to such user providing us with approval to access the device address book).

Explicit commitments that benefit the user, such as data minimization, strong security, or clear user controls.
Not clearly stated: The document states that messages not delivered within up to 2 weeks will be deleted from servers. It also states the company does not read or listen to the content of messages/calls made privately and does not store them once delivered. While these imply data minimization, further clarification on storage duration for delivered messages and explicit commitments on data minimization for other data types would strengthen this section.

End-to-End Encryption for Core Features
Viber's core features, including one-on-one calls, messages, group messages, private media sharing, and linked devices, are secured with end-to-end encryption. This means that only your devices store the encryption keys, and Viber itself cannot access them.
Why it helps: End-to-end encryption ensures that the content of your private communications is highly secure and accessible only to you and the intended recipients, enhancing your privacy and data security.
Starting with Viber 6.0, Viber’s core features are secured with end-to-end encryption: Viber one-on-one calls, one-on-one messages, group messages, private media sharing and linked devices. This means that the encryption keys are stored only on your devices and no one, not even Viber itself, has access to them.
