Is QMT Engine safe?

Clean risk

QMT Engine sends Amazon product and listing details to its websocket backend.

On supported Amazon marketplace pages, QMT Engine content scripts collect product and listing details such as ASINs, page URLs, search terms, prices, ranks, seller details, images, descriptions, dimensions, and release dates. The background script adds tab and stored user-token context before forwarding those messages to QMT's websocket backend.
