Quantcast Partners

Last Updated: November 09, 2021

We partner with other companies to help us provide and improve our services and products. Sometimes, it is necessary for us to share information that could be considered to be personal information about you with these partners. (Remember that we don’t share directly identifiable information about consumers, such as your name or address, because we do not collect that type of information, as discussed in our Privacy Policy). Below is the list of Quantcast partners with whom we share personal information with in order to build and deliver products to our clients. We try to keep this list of partners up to date, so from time to time this list will be updated. This list identifies partners with whom we share information, along with links to their privacy policies so that you can learn more about their data collection and usage practices.

For partners with whom we share information about European consumers, the list includes the partners that are “controllers” of the personal information we share with them. In short, under European privacy law, the controller is the party who determines the “why” and “how” of the processing of personal data. The controller controls and is responsible for this data.

We are continually improving our services and our partners will change over time. We will update this page to reflect those changes. Please visit our Privacy Policy for more information about Quantcast’s data practices.

Ad Serving

The companies in this category serve digital advertisements on various digital platforms such as the web, social media, or mobile apps, and issue reports on the performance of advertising campaigns (e.g., the number of users who saw a particular ad, the particular ad type that was served, etc.). We need to use these vendors to deliver and track the advertising campaigns that we serve, and we share online identifiers (e.g., an auction ID) in order to effectively use their services.

Ad Verification

These companies provide a technology to ensure that digital advertisements appear on intended sites and reach the targeted audience; examples include measuring the viewability of an ad, brand safety and fraud (e.g., whether a site is safe for the particular advertiser’s brand or whether it is a fraudulent site). We use these vendors in order to better meet the requirements of our clients and deliver more effective advertising. These companies receive online identifiers (e.g., user IP addresses and auction IDs).
