Is StreamSync safe?

Clean risk

StreamSync sends Twitch VOD identifiers from Twitch playback pages to streamsync.fr to fetch music timelines.

When you open a supported Twitch VOD or Twitch player page, StreamSync extracts the numeric video ID from the page URL. Its background service worker sends that ID to streamsync.fr to fetch the matching music timeline, and includes a StreamSync authorization token if you are logged in.

Where it sends data

Destinations our analysis observed StreamSync 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.
