Is AuctionGate safe?

Medium risk

AuctionGate uploads your Manheim session cookies and auction visit data, including IP and location, to auctiongate.io.

After you sign in to Manheim, the extension reads all manheim.com cookies and sends them with your auction account ID to auctiongate.io. On lot pages for Manheim, Copart and IAAI it also sends your auction username, buyer number, browser fingerprint, IP address and approximate location, even when you have no AuctionGate login.

Shared hosts - 17 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
