Is Viewstats - YouTube analytics safe?

Low risk

Viewstats records YouTube viewing and interaction events and sends them to api.viewstats.com.

When you use YouTube, the extension records the current page URL, page title, browser user agent, video details, and interaction events such as playback, focus, scrolling, clicks, and navigation. Its background script posts those event batches to Viewstats with fields such as session ID, video ID, channel name, time spent, playback positions, and processing time.

Shared hosts - 6 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.

Where it sends data

Destinations our analysis observed Viewstats - YouTube analytics 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.
