Is Substital safe?
Substital embeds the GiveFreely affiliate SDK and sends device and user IDs to GiveFreely when its popup opens on merchant sites.
When the Substital popup opens, it injects the bundled GiveFreely adunit SDK (v1.17.6) into the active tab. The SDK checks whether the current page is a registered affiliate merchant and fires analytics events — including a persistent device ID and a GiveFreely user ID — to a remote events endpoint. The extension also includes a hardcoded OpenSubtitles API key in its bundle and broadcasts the currently-playing Netflix video title via a wildcard postMessage.

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.

Where it sends data
Destinations our analysis observed Substital 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.
