Additionally, the website may contact you directly.
If the website has granted your request to access hidden data, you will receive a notification in your Quantcast account. Once you’ve been granted access, viewing the reports is as easy as going to that publisher’s profile. The data that was previously hidden will now become visible (you must be logged into your Quantcast account). Note that the website may at anytime recall data access rights.
