The opt-out below will set an opt-out cookie in your web browser. Later, when you are on other websites using this same browser profile and we see the opt-out cookie, we will know the selection you have made and will act accordingly.

Important things to know about the cookie-based opt-out for web browsers:

• This opt-out will stop our services from collecting and using personal information linked to your browser for interest-based advertising purposes
• You will still continue to see ads after opting out, but they may be less relevant to you  
• If your opt-out cookie is deleted or blocked, we will no longer be able to see your selection and you will need to set your cookie preferences again 
• If you use different browsers, browser profiles, or devices, you will have to opt out separately on those since we are not able to access the opt-out cookie across different browsers or devices
• This opt-out is for web browsers, not mobile apps or video or game platforms; see below for additional details 
• This opt-out is also not for audience matched advertising that uses identifiers based on email addresses, phone numbers, or other direct identifiers; see below for additional details
• This opt-out will not unsubscribe you from Quantcast’s marketing emails; see the Quantcast Website and Corporate Privacy Policy to learn more about your email marketing choices 
• This opt out will not affect your Consent Management Platform (CMP) selections. A CMP is a process, usually a pop-up, that a website/digital property uses to assist them in managing users’ privacy preferences in relation to cookies and to help them meet their transparency obligations under data protection and privacy laws. When a user visits a website and is presented with banners, pop-ups, or sliders to manage their cookie preferences, these options are often being managed using a CMP.

If you disable cookies in your browser, or use a browser that does not allow cookies, we cannot associate your opt-out selection with cookies. Instead, we associate your opt-out selection with a unique identifier based on your device’s IP address and other information about your device, and we will stop collecting and using personal information from your device for interest-based advertising purposes based on the IP address-based identifier. 

Your IP address may change over time or as you move between networks (e.g., between home and office). When your browser moves to a new IP address, it will have a new IP-based identifier. Your previous opt-out selections will not be associated with the new IP-based identifier. We will collect and use personal information for interest-based advertising purposes based on the new IP address-based identifier until you opt-out from the new IP address. Important things to know about the cookieless opt-out for web browsers

• This opt-out will stop our services from collecting and using personal information linked to your web browser for interest-based advertising purposes
• You will continue to still see ads after opting out, but they may be less relevant to you,  
• If you use different browsers, browser profiles, or devices, you will have to opt out separately on those, since the IP address-based identifier would be different for each one 
• Because our opt-out is based on your device’s IP address and other information about your device, if that information changes, the identifier we use will change and an opt-out from a previous identifier will not be applied to the new IP address until you opt-out from the new IP address
• This opt-out is for web browsers, not mobile apps or video or game platforms; see below for additional details
• This opt-out is also not for audience matched advertising that uses identifiers based on email addresses, phone numbers, or other direct identifiers; see below for additional details
• This opt-out will not unsubscribe you from Quantcast’s marketing emails; see the Quantcast Website and Corporate Privacy Policy to learn more about your email marketing choices  
• This opt out will not affect your Consent Management Platform (CMP) selections. A CMP is a process, usually a pop-up, that a website/digital property uses to assist them in managing users’ preferences and to help them meet their transparency obligations under data protection and privacy laws. When a user visits a website and is presented with banners, pop-ups or sliders to manage their cookie preferences, these options are often being managed using a CMP.

In addition to the cookieless opt-out described above, in order to meet our obligations under applicable law, we follow a strict data minimization process. Specifically, we use each IP address-based identifier for a maximum of 30 days. After that time, we create a different identifier, which we do not link to the previous identifier. Data is retained with the prior identifier for up to 30 additional days for security and anti-fraud purposes. Therefore, if you wish for Quantcast to stop processing personal information it has about you in association with an IP-address based identifier, such processing will cease within 30 days for all purposes except security and anti-fraud, which will cease after 60 days.

Additional Web Browser Opt-Out Options

You may opt out of interest-based advertising from certain companies by using one or more of the following industry opt-out pages: 

• in the US: https://youradchoices.com/ and https://optout.networkadvertising.org/  
• in Europe: https://youronlinechoices.com/ 
• in Canada: https://optout.aboutads.info/?c=3&lang=en

Please note that the list of industry opt-out tools above is not intended to be exhaustive and there may be a different opt-out tool/consumer choice mechanism available in your country/region. Please also note that not all companies that participate in industry opt-out options offer a cookieless opt-out option at this time.

Global Privacy Control (“ GPC ”) is a preference that you can set in certain web browsers to inform the websites you visit that you do not want information about your online activity collected over time and across third-party websites or online services. We honor GPC for data subjects in the United States.

See the Global Privacy Control Organization page for detailed instructions on how to enable GPC in your web browser.

Quantcast has integrated with IAB Europe’s TCF v2 and, where website publishers have implemented TCF-compliant Consent Management Platforms (CMPs) on their properties, users are able to manage their choices with respect to the processing of personal information collected on the website through the CMPs on the relevant website. 

Screenshot examples of a CMP are below for illustrative purposes. A user can opt out by moving the toggle to the appropriate setting. In the first example, a user can opt out by moving the toggle to the right, in which case the toggle will indicate that the user has opted out by turning red and displaying an “x”. In the second example, the user can opt out by moving the toggle to the left, in which case the toggle will be changed to “off.”

Both the cookie-based and cookieless opt-out options described above work with web browsers only. Though different browsers have different privacy settings, the underlying technology is similar from one browser to the next. 

For mobile devices, TVs, streaming boxes, game consoles, etc., every manufacturer chooses their own approach; it is not standardised. Moreover, different apps on those platforms might have their own privacy settings. 

Mobile Devices 

When using web browsers on mobile devices, the browser-specific opt-out mechanisms described above apply.

For mobile apps, because we are unable to set an opt-out cookie that we can access across different apps, you will need to consult your device’s settings for instructions on how to manage your privacy and advertising choices. See the Network Advertising Initiative (NAI) Mobile Opt-Out page for detailed instructions on how to set opt-out preferences on your device.

TVs and Other Devices

For TVs and other streaming devices, because we are unable to set an opt-out cookie that we can access across different devices and apps, you will need to consult your device’s settings for instructions on how to manage your privacy and advertising choices. See the Network Advertising Initiative (NAI) Connected TV Choices page for detailed instructions on how to set opt-out preferences on your TV or streaming device. Additionally, particular apps on TVs or gaming devices might offer their own privacy settings. Again, check their settings and documentation for details. 

Some devices, particularly mobile devices, offer specific settings that control the sharing of location information. Check your devices’ and apps’ privacy settings and documentation for details.

Some companies, with appropriate permissions, might use your email address to create an identifier that can be matched across websites, apps, and devices and used for interest-based advertising purposes. 

The Network Advertising Initiative (NAI) has a web-based tool (available here) that allows users to opt out of participating members’ use of their email addresses for advertising purposes.
