Note: Sync is currently only available in the Snapshot version of Vivaldi. Find out more about the difference between Snapshot and Stable on the Vivaldi Blog.

What information can I sync?

Currently, Vivaldi supports synchronizing of the following items:

  • Bookmarks and Speed Dials;
  • Settings (only some of them for now. Work is in progress to allow syncing most of them);
  • Stored webpage passwords;
  • Stored autofill information;
  • History and remote sessions (only typed URLs for history at the moment);
  • Extensions;
  • Notes.

How do you protect my data?

Your data is protected using end-to-end encryption. The data you send us is encrypted on your computer using a password that is never sent to us. In addition, the servers on which your encrypted data is stored are well protected from intrusion both physically and from the network.

What happens when I stop syncing some or all of my data?

When you choose to stop syncing some types of data, the browser forgets all association between your local data and the data located on the Sync server. All your data remains on the Sync server as it was. When you explicitly log out from Sync, the same happens for all the synced data. Please note that shutting down the browser does not log you out from Sync.

What happens when I log in to Sync with a new client or resume logging some data type?

When you log in or enable synchronization of some data type, your local data is merged and reassociated with what exists on the server. This is done in a way that ensures you won’t lose any data (but some things like bookmarks can be moved to match the location the server believes they are in).

How do I remove my synced data from your servers?

You can do so easily from the Sync settings dialog.

I want to be able to sync more data. What will be supported in the future?

The immediate plan is to add the ability to sync all Settings, then search engines and allow for syncing more browsing history. If all goes well, we hope to provide synchronization for every feature that can benefit from it.

Vivaldi’s Sync is based on the Chromium sync engine. Will it allow me to synchronize my data with Chrome?

No. Vivaldi does not use the Google sync server and therefore it cannot share data with Chrome. Even if we wanted to do that, the changes we have made to the engine would make it incompatible with the Chrome synchronization.

Can I keep my Sync data on my own server?

Not at the moment. We hope to make this possible in the future once we are confident that our server implementation is ready to be open-sourced.

How long does it take for changes on one Vivaldi instance to be reflected everywhere?

When one Vivaldi instance sends new data to the Sync server, a notification is sent immediately to all other Vivaldi instances to let them know that they can download this new information. In good conditions, this means you should see changes reflected within a minute.

Why are there two passwords? Can I just use one?

When setting up Sync, you will need to use one password for logging in to (your login password) and one password that is used for encrypting your data (your encryption password). Your login password is sent to our servers over a secure connection and a hash of it is stored in our databases. Your encryption password is used locally on your computer for encrypting the data you are about to send to our servers. Your encryption password is never sent to us or any other third party, which ensures that we cannot decrypt your data.

When prompted for an encryption password, you have the option to reuse your login password for convenience, but this is *strongly* discouraged because it means you are encrypting with a password you are also occasionally sending over the internet and is thus more vulnerable to attacks.

I’ve lost my encryption password or want to change it. How can I do that?

In both instances, you will need to delete your Sync data from our servers and set up everything again. This should not cause you to lose any data, as long as you have the ability to run one Vivaldi instance that has all of your data.

I’ve lost my login password or want to change it. How can I do that?

You can visit and change it there. We hope to make this available directly from the browser’s user interface sometime in the near future. Also, note that if you have chosen to use the same password for login and encryption, changing your login password will not automatically change your encryption password to be the same and you will have to do this separately.

I don’t want to use Vivaldi Sync anymore. How can I remove my account?

Your account can be used for a number of things aside from Sync, like participating in our Forums, using our blogging platform or the Vivaldi webmail. Therefore, we recommend that you keep your account even if you stop using Sync. If you still want to delete it, please note that it is currently not possible. We kindly ask you to drop us a message on sharing your username and email address so that we can do it for you. Soon, you will be able to do this yourself.
