What We Do
We have two main product suites: (1) Quantcast Measure and (2) Quantcast Advertise. Our Measure products help website owners to understand the interests and demographics of the people who visit their sites. (Here’s an example.) Our Advertise products allow businesses to deliver relevant online advertising to individual consumers. For companies that want to advertise online, our Advertise products help get their ads in front of the people that are more likely to find them interesting. For consumers, we provide ads that are more useful and relevant to their interests. And for websites, our Advertise products help drive advertising revenue, without which the free Internet we all use every day would not exist. In short, we try to make online advertising more efficient and pleasant for everyone. In order to do all this, we collect and analyze information about individual consumer interests and demographics.
We also offer Quantcast Choice, a consent management tool for publishers and advertisers built on the IAB Europe Transparency & Consent Framework that helps website operators provide consumers with information and choices about data. From time to time, we may offer additional products.

Some Helpful Terminology
A tag is a tiny snippet of code inserted into a Partner’s website content that is used to collect data related to a website visit. Similar functionality is enabled in a Partner’s mobile app through the use of an SDK (Software Development Kit). When a user views a Partner’s website or uses a Partner’s app, our servers are notified, and we are able to collect information from the browser or application. See our FAQ for more information about our Tags and SDKs.
Log Data includes (1) information sent to Quantcast by browsers that encounter our Tags, including, for example, browser type, browser time, time of access, screen resolution, IP address, referring site URL, current site URL, and search strings; (2) information sent to Quantcast by advertising exchanges in the form of bid requests, which may include the information above as well as information like auction identifiers, for the purpose of soliciting bids to place online ads; and (3) information received from the Quantcast SDK embedded in mobile apps, which may include the above as well as information like mobile advertising identifier, location information, application data and usage information, and unique application and installation identifiers.
Personal Information (also sometimes called “Personal Data”) is information that is associated with an individual and may enable that individual to be directly or indirectly identified. Through the use of our tags, SDKs, and cookies, we collect Personal Information about you; the Personal Information that Quantcast collects does not include information that may be used to identify you directly (for example, Quantcast does NOT collect your name or email address). However, Quantcast does collect information that may indirectly identify you. Some information transmitted by Cookies and Tags including Log Data are Personal Information. Quantcast may also receive some information about you from third parties and we may combine such information with personal information we collected about you ourselves. However, while we make predictions about your interests and demographics based on this information, we do not know who you are. For more information about the Personal Information that we collect, please visit our FAQ page
Quantcast Partners (“Partners”)
Our Partners include the site operators and mobile application developers that request that we collect information about the visitors to their sites and users of their apps through our products.
Our Partners also include companies that we work with to provide the Services.
For more information about our Partners, including what types of partners we have and what types of data we share with them, please visit our Partners page.
Quantcast Services (“Services”)
This term refers broadly to the entire set of services that we provide through our products, including the collection of Personal Information, the analysis of that information, the provision of that information and insights derived from that information to or for our Quantcast Partners, and the selection and placement of optimal advertisements and content based on that information.
Information Collection and Use
Legal Bases for Collection and Use
In addition, where you have given us consent to use your information in certain ways, we will rely on your consent to process the information. You may revoke that consent at any time. Please see the How To Object and Opt Out section below for information as to how you may withdraw your consent.
Information Collected from the Quantcast Site
When you visit Quantcast.com, our servers record and collect Log Data automatically sent by your browser. We use the Log Data to monitor, analyze, administer, and improve the Quantcast Site and our Services. As described below in the section Information Shared with Our Service Providers, we also allow some Partners to place tags on our Site.
We require our Quantcast Partners to provide some business contact information as part of signing up to use our products, such as full name, contact email, physical address, and telephone number. We use this business contact information to provide the Services, contact you about the Services, administer accounts, and address questions and issues you might have. We don’t use this business contact information to serve you advertisements.
If you contact us by email, we keep a record of your contact information and correspondence for as long as necessary to deal with your correspondence and the issues you raised. If you provide contact information to us, we may use that information to contact you with Quantcast newsletters, marketing, or promotional materials. If you decide at any time that you no longer wish to receive such communications from us, please follow the unsubscribe instructions provided in any of the communications.
Information Collected through our Services
When you visit a site or app operated by a Quantcast Partner, the Partner permits Quantcast to collect Log Data from their sites and apps through the use of Tags and Cookies; we also receive information directly from our Partners. We associate this information with a unique random identifier associated with your device (like a cookie ID), but we never associate it with your name, email, address, or phone number, because we don’t collect that type of directly identifying information about consumers. We use this information from Partners, which includes information about some of the sites you are visiting and some of the apps you are using, as necessary for our legitimate interests to help improve the accuracy of our products and to determine what advertisements and content might be interesting to you. For example, if you were recently searching for plane tickets to San Francisco, we might predict that you are interested in purchasing a nice warm sweater, and then show you an ad from one of our Advertising clients that sells sweaters. (To be more precise, we would predict that your device might belong to a person interested in sweaters, because we don’t know who you are.)
We do not link Log Data to your name, address, email, or phone number, or otherwise attempt to discover your identity. We employ appropriate organizational and technical security safeguards to keep information about you secure and to make it difficult for us to associate it with your identity.
When you visit a site or app that uses Quantcast Choice, including the Quantcast Sites, we may use tags, cookies, SDKs, and plug-ins to store information about privacy notices that you have received and privacy choices that you have made. We do this pursuant to the IAB Europe Transparency & Consent Framework’s policies and technical specifications. We do not use any information collected from Quantcast Choice for other purposes. In other words, we do not use that information to inform our Measure and Advertise products outside of understanding the privacy notices you have received and privacy choices you have made.
Information Sharing and Disclosure
Information Shared with Our Partners
Information Shared with Our Service Providers
We use third parties and Quantcast partners to help us administer and improve our products. For example, these companies assist with hosting, data processing, database management, and administrative tasks on our behalf. These third parties and partners have access to information about you, including through the placement of Tags on our Site, to perform these tasks on our behalf. To learn more about service providers for consumer information, please visit our Partners page.
Information Disclosed for Our Protection and the Protection of Others
It is our policy to protect you from having your privacy violated through abuse of the legal system. We reserve the right to disclose information about you to government or law enforcement officials or private parties as we, in our sole discretion, believe necessary: (i) to comply with any applicable laws, regulations, and valid subpoenas, warrants, and court orders; (ii) to protect the rights, property, and safety of ourselves, third parties, or the public in general; and (iii) to prevent or stop activity we consider to be illegal or unethical.
Information Disclosed in a Change of Ownership
Quantcast may sell, transfer, or otherwise share some or all of its assets, including information we collect about you, in connection with a merger, acquisition, reorganization, or sale of assets or in the event of bankruptcy. We may also make certain information available to a potential investor or purchaser (and their advisers) in advance of any such transaction completion.
We provide a cross-platform reporting service to Partners that operate both websites and mobile apps. To accomplish this, we rely on hashed (i.e., scrambled) identifiers derived from user logins to associate your usage across mobile and desktop platforms. This allows our Measure product to provide meaningful reports across platforms for a single Partner. We also sometimes use Log Data or other data from our Partners to make guesses about associations between devices or platforms.
How to Object and Opt Out
If you prefer not to receive interest-based content and ads enabled by Quantcast, you can object and opt-out by clicking on the Quantcast “Opt Out” link here. Additionally, we are a member of the Network Advertising Initiative (NAI) and participate in the Digital Advertising Alliance’s (DAA) Self-Regulatory Program. Each of these programs provides an opt-out feature where consumers can choose not to receive targeted advertising from any NAI or DAA affiliate. These links will take you to the NAI opt out and the DAA opt out. If you are located in the European Union, you may prefer to use the EDAA opt out. If you choose to opt-out, we will place a cookie on your device which is associated with your browser that identifies you as having opted out. Then you will not receive interest-based content or advertisements enabled by Quantcast and we will not log your website visits or other online media consumption. Because our opt-out is cookie-based, your browser must be set to accept third party cookies. If you use multiple devices or browsers, you’ll have to opt out on each. If you delete the opt out cookie, you will need to opt-out again.
Where you have provided Quantcast with consent to use your data, you may revoke that consent at any time. Where you have used Quantcast Choice to provide your consent to Quantcast or other vendors, you may visit the website where you gave that consent at any time to update your choices.

For example, you have the right to access your information and to have inaccuracies in your Personal Information corrected. In many cases where we process your information, you may also have a right to restrict or limit the ways in which we use your information. You also have the right to object to the processing of your Personal Information and to have it deleted in certain circumstances. You also have a right to obtain a copy of your Personal Information in an easily accessible format. For these purposes, go here.
We employ administrative, physical, and technical measures designed to protect the confidentiality and integrity of Personal Information that we store. These measures may include encryption and employment of information storage security technologies to restrict access to our network. Please be aware that no method of transmitting information over the Internet or storing information is completely secure. We have procedures and security features in place to help keep your data secure once we receive it. Additionally, in some instances our Partners or others may provide information to us in unencrypted form.
Quantcast operates a global service. Your information is transferred internationally between Quantcast affiliate companies and our Partners to countries around the world including the United States, where the privacy and data protection laws may be different than those in your jurisdiction. We use standard contractual clauses approved by the European Commission, and may rely on the European Commission’s adequacy decisions about certain countries, as applicable, for data transfers from the EEA to the United States and other countries. You can contact us to request a copy of our Standard Contractual Clauses.
Our Policy Toward Children
Quantcast does not knowingly collect or use data from children under 16.

If we become aware that a child has provided us with Personal Information, we will delete such information from our files.
Health and Sensitive Information

We provide a list of standard health segments and a representative sample of custom health segments used by Quantcast for the purposes of Interest Based Advertising. Please note that in certain jurisdictions the creation and use of health segments by Quantcast is restricted in line with legal and/or self-regulatory requirements. In the EEA, Quantcast does not knowingly collect or utilize any Personal Information revealing racial or ethnic origin, political opinions, religious or philosophical beliefs, or trade union membership, genetic or biometric data for the purpose of uniquely identifying an individual, or data concerning an individual’s health, sex life, or sexual orientation, as well as Personal Information related to criminal convictions and offenses.
