About Sync service

This service aims to provide users with the ability to synchronize the information recorded in their Vivaldi web browser (such as bookmarks, settings, passwords and browsing history) with a web browser they are using on a different computer. This is done for users voluntarily choosing to enable the feature.

Types of data we collect and for what purposes

The data is encrypted, sent to Vivaldi servers located in Iceland by the user’s Vivaldi browser in the form of individually encrypted entries for each separate data item. Similarly, the user’s Vivaldi browser can request to retrieve the data from the server and decrypt it using the user’s key. Vivaldi servers also send a notification to any logged in Vivaldi Browser over an encrypted connection.

Alongside that data, we store some metadata that allows us to ensure the integrity of the stored data. This metadata includes: the user to which each encrypted entry belongs; the datetime at which the user started using sync; the datetime of the user’s last connection to sync; some encryption information; the type of each entry (whether it is a bookmark, a password, a tab, etc); whether the entry was deleted (deletions are synced); the parent of the entry (for tree structures, like bookmarks); the identifier of the client on which the entry was created; and the times at which the entry was created and last modified.

In addition to this, we keep track of error logs emitted by the server software whenever an unexpected state (error) occurs. These logs contain a user name, a timestamp and other non-sensitive data. They are kept for up to 30 days.

Retention and deletion

The users data is kept for up to a year from the last time the user interacted with Vivaldi sync service or until the user requests their deletion.


Vivaldi has strict restrictions on access to user data. Only a limited number of Vivaldi’s employees or employees at Vivaldi’s service providers for the web hosting services have access to such data.


Vivaldi will not transfer any personal data to third parties except as required by law or law enforcement.
Vivaldi’s servers are hosted at the Hringdu data centers in Iceland.


Procedures are reviewed regularly to ensure that the policies are followed. Any non-conformance regarding the policies will be corrected without unnecessary delay.
