Is Sync Watch safe?

Clean risk

Sync Watch sends shared tab details and video playback state to server.syncwatch.space for room synchronization.

When a user joins a room and clicks Share, Sync Watch sends the active tab title, URL, and user name to its Socket.IO server. While connected, its content script also watches video elements and forwards playback events such as play or pause state, frame location, current time, and playback rate for the selected tab.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data

Destinations our analysis observed Sync Watch contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
