Is Tournesol Extension safe?

Clean risk

Tournesol Extension sends the current YouTube video ID to api.tournesol.app to fetch rating statistics.

When you open a YouTube watch page, Tournesol Extension reads the video ID from the page URL and requests Tournesol rating statistics for that video. The request goes to api.tournesol.app and may include the extension's stored bearer token when one is available.

What this publisher told the store about itself, and the other listings that told it the same thing.

Shared hosts - 2 hostnames

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.
