Is Ace Script safe?

Low risk

Ace Script lets any website ask the extension to start the local Ace Stream native engine.

Ace Script watches every page for a specific page element and sends a StartEngine command when that element appears. The background script passes that command to the local org.acestream.engine native messaging host, which can launch the Ace Stream engine if it is installed.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Ace Stream - no other listings under this identity, 1 shared hostname

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

Ace Stream

Shared hosts - 1 hostname

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.
