What We Do
We have two main products: (1) Quantcast Measure and (2) Quantcast Advertise. Our Measure product is free, and it helps websites owners to understand the characteristics and demographics of the people who visit their sites. (Here’s an example.) Our Advertise product allows businesses to deliver relevant online advertising to individual consumers. For companies that want to advertise online, our Advertise product helps get their ads in front of the people that are most likely to find them interesting. For consumers, we provide ads that are most useful and relevant to their interests. And for websites, our Advertise product helps drive advertising revenue, without which the free Web 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.
Some Helpful Terminology
A cookie is a small file containing a string of characters that is sent to your computer when you visit a website. They typically are used to store user preferences or IDs. Some cookies are set by the site you are visiting, and others are set by that site’s service partners. Cookies allow the site and services to recognize your browser. And the site or service that places a particular cookie has permission to read the contents of that cookie each time it communicates with your browser.
Quantcast Tags are tiny graphics our Partners place on their web pages and lines of code they include in their apps. (In the apps, this code is called an SDK.) When a user views a site, or uses an app, with one of our Tags, our servers are notified, and we are able to collect information from the browser or mobile device.
Log Data includes (1) information sent to us 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; and (2) information received from the Quantcast SDK embedded in mobile apps, which may include the above as well as device identifier, location information, application data and usage information, and unique application and installation identifiers.
Personally Identifiable Information (“PII”)
Personally Identifiable Information (PII) is information about you that can be used to contact you or identify you as an individual. PII may include: your name, user name, phone number, email address, and physical address.
Non-Personally Identifiable Information (“Non-PII”)
Non-PII refers to information about individuals that, in some cases, might serve to identify a device or browser but does not identify any individual person. For example, we consider the following to be Non-PII: your ZIP code, approximate location (e.g., region, city, ZIP), your browser type, cookie IDs, device identifiers, IP address, websites you may have visited, and advertisements viewed or clicked. We also consider aggregated, de-identified, and/or anonymized data to be Non-PII. Not all jurisdictions have the same definition for PII and Non-PII. Some jurisdictions consider IP addresses to be PII. When Quantcast stores an IP address, we store it in truncated or encrypted form.
Quantcast Partners (“Partners”)
These are the site operators and mobile application developers that allow us to collect information via Tags about the visitors to their sites (and users of their apps), through either our Measure product or Advertise product.
Quantcast Services (“Services”)
This refers broadly to the entire set of services that we provide through our Measure and Advertise products, including the collection of consumer information, the analysis of that information, the provision of that information to or for our Quantcast Partners, and the selection and placement of optimal advertisements based on that information.
Information Collection and Use
Information Collected from the Quantcast Site
When you visit Quantcast.com, whether as a Visitor or a Registered User, 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. We require our Quantcast Partners to provide some PII as part of signing up to use our Measure and Advertise products, such as full name, contact email, physical address, and telephone number. We use this PII mainly to provide the Services, to administer accounts, and to address questions and issues you might have.
If you contact us by email, we may keep a record of your contact information and correspondence. 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 us to collect Log Data (defined above). We associate that information about your site visits or app usage with a unique random identifier (your cookie ID), not with your name, email, address, or phone number. We use this information to help improve the accuracy of our Measure product (discussed above) and to determine what advertisements might be interesting to you. For example, if you were recently searching for plane tickets to San Francisco, we might predict that you would be interested in purchasing a nice warm sweater, and then show you an ad from one of our Advertising clients that sells sweaters. (Technically, to be more precise, we would predict that your identifier might belong to a person interested in sweaters, because we don’t know who you are.)
Information Sharing and Disclosure
Personally Identifiable Information
We will not share or disclose your PII to any third party, except as requested by you or as discussed below in the section on information shared with our service providers.
Non-Personally Identifiable Information
We may share with third parties Non-PII, including certain Log Data, as part of providing and improving our Measure and Advertise products. For example, we may disclose such data to companies involved in ad delivery or ad visibility. Likewise, we may disclose such data in order to provide or facilitate site audience measurement, traffic analysis, or demographic analysis, and to enable websites to provide their advertisers with audience segments that are appropriate for their products or services.
Information Shared with Our Service Providers
We may use third parties and Quantcast affiliate companies to help us administer and improve our Measure and Advertise products. For example, these companies may assist with hosting, data processing, database management, and administrative tasks. These third parties and affiliates may have access to your PII (if you submitted such data to Quantcast) and Log Data, but only to perform these tasks on our behalf, and they are obligated not to disclose or use it for any other purpose.
We also receive Demographics and Interest Reporting data about the Quantcast Site from one of our service providers, Google Analytics. This data is used purely to satisfy our own curiosity about the type and quality of Demographic and Interest Reporting that Google provides. If you like, you can opt out of Google Analytics through Google’s Ad Settings.
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. But 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 your PII and Log Data, in connection with a merger, acquisition, reorganization, or sale of assets or in the event of bankruptcy. We may also make certain PII or Log Data available to a potential investor or purchaser (and their advisers) in advance of any such transaction completion.
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 your Log Data secure and to prevent it from being related to your PII.
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 rely on Log Data to make cross-platform associations.
Data Retention Policy
We retain Log Data for 13 months to accommodate seasonality. It is then permanently deleted. This is the longest period of time that we will retain the Log Data we collect through our Measure and Advertise products.
How to Opt Out
If you prefer not to receive interest-based content and ads enabled by Quantcast, you can 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. After you opt-out, we will place a cookie on 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 pattern of 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 cookie, you will need to opt-out again.
Accessing, Changing, or Deleting Your Information
We employ administrative, physical, and technical measures designed to protect your information from unauthorized access. These measures may include encryption of information you provide and employment of information storage security technologies to block access from outside our network. Please be aware that no method of transmitting information over the Internet or storing information is completely secure. Additionally, in some instances our Partners or others may provide information to us in unencrypted form.
Our Policy Toward Children
Quantcast does not knowingly collect PII from children under 13. If a parent or guardian becomes aware that his or her child has provided us with PII without their consent, he or she should contact us. If we become aware that a child under 13 has provided us with PII, we will delete such information from our files.
Quantcast does not knowingly collect or utilize any sensitive health-related information, such as, for example, information related to past or present medical conditions or prescriptions. We do assist some of our advertising clients in serving ads for their health, medical, and wellness related products. We also provide the following standard segments related to health and wellness: cosmetics, diapers, hair care, and mouthwash.
