How Does Sync Work?



I had a few questions on how Brave bookmark sync feature worked.

  1. Does it save my bookmarks in the cloud? Or on a blockchain? Or is it just saved on your device?

  2. If the bookmarks are saved on a cloud or blockchain are they encrypted at rest?

  3. When syncing between devices is the data encrypted in transit?

  4. If they bookmarks are only stored on devices and not on a cloud or blockchain are there any plans to add this feature in the future?

Sync was activated today. How dows it work? Curious

Hi @trymeout

Does this help.


The above link is for how to Sync but, if I understand correctly, it seems like you’re interested in the technical details of the process.
This article is a bit older (in the process of re-documenting this) but more or less outlines the Sync process “under the hood”:


From the links I read it seems sync bookmarks are stored on an Amazon S3 server? But my identity is not stored on the server in any way since your email, phone number, or name is not require to use sync?

Is this right?

Also is sync data encrypted in transit? It does say in the link above it is encrypted at rest and Brave cannot read users sync data.


Hi @trymeout.

Yes on S3. And no identity, no email/password/phone number/name no nothing. There’s a sync code via words and QR code that chains the devices together.


@rebron2000 is it correct that the sync feature does not work yet on IOS devices? I just tried to sync my iPhone with my Mac, but there was no sync option (to read scan the code) on the iPhone Brave.

Any idea (I know, no commitment) when the IOS version will become available?


Hi @iherman. We’re in testing (QA) with it on iOS, will be sooner than later.


Sounds good, looking forward to it!
