Is Quantcast - Tag Inspector safe?

Clean risk

Quantcast - Tag Inspector sends detected Quantcast pixel pcodes and the active tab domain to Quantcast APIs.

It watches completed requests to quantserve.com and quantcount.com pixel URLs and stores parsed tag data for the tab. When the popup opens, it sends the detected pcodes to www.quantcast.com and uses the active tab's domain in follow-on planner and report requests.
