Is Ground News Bias Checker safe?

Clean risk

Ground News Bias Checker sends HTTPS page URLs to extension.ground.news to look up related news events.

When a tab updates on an HTTPS page, the background script sends the page URL to Ground News's search endpoint to check whether there is a related news event. If the response contains an event, the extension can open its popup on the page; when a stored session ID and article reference are present, it also records the open with Ground News's tracking API.

Ground News

Shared hosts - 4 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.
