Viber says private messages and calls are end-to-end encrypted

Viber says its one-to-one and group messages, private media sharing, and one-to-one calls are end-to-end encrypted.

Viber keeps call and messaging activity records for 24 months

Viber keeps raw activity records for free calls, messaging, and in-app activity for 24 months, including details such as who contacted whom and when.

If you use AI tools, Viber processes the text you submit

If you choose AI features such as summaries or message polishing, Viber processes the text or content you submit to provide the feature; it may be sensitive.

This applies only if you choose to use an AI feature and submit content to it.

Private communications are not used to train AI models

Viber says it does not use private communications to train its AI models or third-party AI models, though chosen AI features process submitted text to provide their service.

If you allow contact access, Viber collects address-book details

If you grant contact-list access, Viber collects names, numbers, and favorites to help show and sync your contacts.

This applies only if you approve the app's access to your phone address book.

Joining can notify people whose shared contacts include your number

If another Viber user shared an address book containing your number, joining Viber can notify that person and add you to their Viber contact list.

This applies only if your number appears in an address book that a Viber user has approved access to and shared with Viber.

Viber may share identifiers and activity for personalized ads

For personalized ads, Viber may share device identifiers and location-related or demographic data with ad partners, and may use activity from Viber and third-party services.

Public posts carry a perpetual license for broad reuse

If you publish in public Communities, Channels, or similar spaces, Viber, partners, and other users get an irrevocable, perpetual license to reuse your content, including commercially.

This applies to Public Content you publish in public Communities, Channels, or other public spaces, not every private message.

Deleting your account does not immediately erase all records

After deletion, call and messaging records remain on their 24-month retention schedule, support correspondence is kept 10 years, and public posts may remain unless you delete them.

Viber can end access without notice and puts data export on you

The terms allow Viber to suspend or stop services without notice and to terminate accounts without notice in specified cases; they put data export on you.

The terms require U.S. users to arbitrate individually unless they opt out

U.S. residents generally must use individual binding arbitration and waive class relief, unless they opt out within 30 days; some disputes are excluded.

Paid purchases may be final, especially after digital content arrives

The terms generally make purchases non-refundable and end cancellation rights for digital content once delivered, subject to legal rights and app-store rules.

This applies only if you make a purchase; app-store in-app purchases follow the relevant app-store refund and cancellation terms.

Some auto-renewing trials require cancellation up to 24 hours early

A promotional trial may renew automatically unless you cancel up to 24 hours before it expires, so the deadline can come before the trial ends.

This applies only if you choose a promotional free trial that has automatic renewal.

If you buy a subscription, it renews automatically until canceled

Paid subscriptions automatically renew for another period; cancel through the purchase channel to stop later renewals, and access continues through the current billing period.

This applies only if you choose a recurring Premium Services subscription.
