Favorites and settings. Open tabs if you choose.
Open tabs, per device.
Off until you turn it on. Each machine publishes its own open tabs, and they never merge with another device’s tabs or rearrange them.
Spaces, if you share them.
Since Blanc 1.45, Spaces you choose to share stay the same on each computer that turns on Spaces and groups: their tabs, tab names, groups and pins merge, and a tab closed in one closes on the others. Off by default, on each device.
Never synced.
History, downloads, permissions, cookies, site data, and private tabs stay on the device.
Reading another device never rearranges it.
Off until you say so, on each device.
Sharing is a per-device switch in Settings, off by default. A machine’s tabs never leave it until you flip the switch on that machine — and flipping it off withdraws them.
Open here, not there.
Another device’s tabs are a read-only list. Picking one opens it as a fresh local tab; nothing force-opens, closes, or reorders on the other side.
Sync belongs to Personal.
Sync is available only to Personal. Named local profiles and independent windows let you separate browsing identities on this device.
Everywhere you already look.
Remote tabs sit behind a folded section in the island panel, match in the Quick Switcher below your local tabs, and appear on the start page under “on your other devices.”
