Data Processing Privacy Policy


This Circulor Data Processing Privacy Policy (also referred to as the ‘Privacy Policy’) informs consumers (‘you’) on the collection, use and sharing (collectively referred to as ‘processing’) of your personal information in connection with Circulor’s provision of data cloud services designed to help Circulor’s customers’ and partners’ online and offline activities (‘Circulor Data Clouds’). This Privacy Policy also explains the choices you have in relation to these processing activities.

This Privacy Policy was last updated on February 25, 2019. However, the Privacy Policy can change over time, for example to comply with legal requirements or to meet changing business needs. The most up-to-date version can be found on this website. In case there is an important change that we want to highlight to you, we will also inform you in another appropriate way (for example, via a pop-up notice or statement of changes on our website).

  • Circulor processes and uses personal data insofar as this is required for the performance of the contractual relationship with the customer.

  • Circulor shall only use personal data above and beyond the requirements for the fulfilment of the contract if permitted to do so by law or if you have provided us with your consent to do so.

  • Circulor may transfer customers' personal data to administrative and prosecuting authorities insofar as this is permitted by law.

As used in this Privacy Policy, ‘personal information’ or ‘personal data’ means information that relates to an identified individual or to an identifiable individual. For example, this could include among other things your name, address, email address, past purchase behavior or information regarding your online interests. Personal information about you that Circulor may process is also referred to as ‘information about you.’ For more detail about the types of information about you that we may process in the Circulor Data Cloud, please refer to Section 4 below.


The Privacy Policy applies to Circulor’s processing of information about you provided to the Circulor Data Cloud by our third party data suppliers to help enable Circulor Data Cloud customers and partners to market products and services to you based on your interests.

The Privacy Policy does not apply to the following activities:

  • First-party information collected about you by Circulor customers. Our customers are responsible for their own personal information collection practices or their use of their personal information for marketing and other purposes, including when they use the Circulor Data Cloud to send you online advertising. To find out more about our customers’ use of first-party information about you, you are encouraged to review the relevant privacy policy of the company who collected your information from you or is sending you advertising. Please consult that company if you have any further questions about its use of information about you.

  • Data collected for Circulor’s own direct marketing purposes. For information about Circulor’s processing activities with regard to your personal information collected on Circulor websites and applications and used for Circulor’s own direct marketing purposes, please refer to Circulor's General Privacy Policy.


Circulor Corporation and its affiliated entities are responsible for processing your personal information in scope of this Privacy Policy. Please refer to Section 18 for contact details and the registered addresses of Circulor Corporation. A list of Circulor entities is available upon request.


Circulor may process both offline and online information about you, including information from publicly available sources or third party data providers.

  • Offline information about you is obtained by Circulor from its offline partners such as brick-and-mortar retail stores, grocery stores and their associated loyalty card programs, payment card brands, catalog orders and consumer survey programs, and third parties who may not have a relationship with you and collect offline information from their offline partners.

  • Online information about you originates from your activities on sites operated by our online partners, such as advertising agencies and website operators (for example, online retail stores or travel sites). Circulor also obtains online information from third parties who may not have a relationship with you and who collect online information using cookies or similar technologies, such as pixels tags and device identifiers, as you browse the Internet and interact with websites. For more information on cookies and similar technologies used in connection with Circulor Data Cloud, please refer to Section 11 below.

Information about you may in some cases directly identify you, while in other cases it may only indirectly identify you. Personal information that is collected offline and that can directly identify you may include, for example:

  • name and physical address, email addresses, and telephone numbers;

  • demographic attributes, when tied to other information that identifies you;

  • transactional data based on your purchases, when tied to other information that identifies you;

  • company data such as the name, size and location of the company you work for and your role within the company;

  • data from marketing opt-in lists, consumer surveys, or publicly available information;

  • IP addresses and information derived from IP addresses, such as geographic location;

  • information about your device, such as browser, device type, operating system, the presence or use of “apps”, screen resolution, or the preferred language;

  • obfuscated personal information such as hashed email addresses (direct identifiers are removed);

  • demographic information such as gender, age, and income range when not tied to information that directly identifies you;

  • behavioural data of the internet connected computer or device you use when interacting with websites, applications, or other connected devices, such as advertisements clicked or viewed, websites and content areas, date and time of these activities, or the web search used to locate and navigate to a website.

We may associate personal information about you with interest segments or profiles as part of the provision of Circulor Data Cloud services to our customers and partners:

  • Interest segments are a specific group of consumers that share a common behaviour or preference used for direct marketing by our customers. For example: in market for travel specials to Hawaii.

  • Profiles are a set of attributes about a specific consumer or device, or a set of multiple consumers or devices sharing common attributes used for marketing by our customers. For example: age bracket 25-55; adventurous traveller; surfing enthusiast; in market for travel specials to Hawaii.


We use personal information for the following purposes:

  • a) to help enable Circulor Data Cloud customers and partners to market products and services to you based on your interests;

Cookies and similar technologies (e.g., pixels tags and device identifiers) are used by Circulor and our advertising technology partners to recognize you and/or your device(s) on, off and across different services and devices for the purposes specified in Section 5 above.

Cookies are small text files that contain a string of characters and uniquely identify a browser on a connected device. We or our Circulor Data Cloud partners may use cookies to, among other things, track user trends and collect information about how you use our customers’ sites or interact with advertising. Most browsers are initially configured to accept cookies by default. You may, however, be able to change your browser settings to cause your browser to refuse third-party cookies or to indicate when a third-party cookie is being sent. Check your browser’s “help” files to learn more about handling cookies.

Pixel Tags (also called web beacons or clear GIFs) are invisible 1 x 1 pixels that are placed on webpages that use this technology for marketing and measurement purposes. When you access these webpages, pixel tags generate a generic notice of the visit. Pixel tags can be used with cookies or alone. When used with cookies, pixel tags can track activity on a site by a particular device and provide relevant online advertising to you. When you turn off cookies or have opted out of cookies, pixel tags simply detect a unique website visit and how you interacted with the advertising but do not track an individual to provide relevant online advertising.

You can opt out of cookies using the opt-out tools in the next section.


We provide multiple choices in respect to the information we process about you. You can exercise these choices as described below.

Opt-out and object to our use of information about you

Circulor offers multiple ways for you to opt out and object to our use of information about you:

  • Circulor Data Cloud Opt out. You can access the Circulor Data Cloud opt-out tool here.

    Please note that if you use this opt-out tool, Circulor will opt you out of Circulor’s use of information about you for Circulor Data Cloud services involving both first-party use of your information as well as any third-party use of your information. See Section 2 above for more information on the distinction between first party and third party information.

  • AdTech Industry Opt Out. You may also opt out of our processing of information about you for Circulor Data Cloud services by using the opt-out tools provided by the following industry groups:

  • Mobile Opt Out. While the opt out methods described above often also work for mobile web browsing, mobile ‘app’ environments do not accept cookies. You may want to consider installing the AppChoices App provided by the Digital Advertising Alliance (DAA) to exercise opt-out control for specific companies, including Circulor, when in a mobile app environment. More information on how to download and configure the AppChoices App relevant for your mobile platform is available here.

  • Do Not Track. Circulor honors “Do Not Track” browser settings, meaning we will not track your browser for marketing purposes while you have “Do Not Track” turned on in your browser settings.

Please note that if you opt out using any of the first three opt out tools, you may still temporarily see interest-based advertising from Circulor Data Cloud customers due to advertising campaigns from those customers already underway. However, you will be opted-out of all future advertising campaigns from customers that use the Circulor Data Cloud.

Also note that the first three opt out tools are currently cookie-based and prevent Circulor from using your personal information for interest-based advertising on the browser on which they are installed. As a result, these opt out tools will only function if your browser is set to accept third-party cookies and may not function where cookies are sometimes automatically disabled or removed (e.g., certain mobile devices and operating systems). If you delete cookies, change your browser settings, switch browsers or computers, or use another operating system, you will need to opt out again. Circulor does not use persistent, unique identifiers to revive a previously opted-out profile or deleted cookie.

If you want to opt you out of Circulor’s use of information about you for Circulor Data Cloud services, but do not want to receive third-party cookies, you can also change your browser settings on your computer or other device you are using to connect to the internet. Most browsers also provide functionality that lets you opt out of all advertising cookies, including Circulor cookies.

Delete information about you

If you would like to submit a request to have online and/or offline information about you, if any, erased or deleted, you can use this form.

Access information about you

In order to exercise your right to access your online information stored in the Circulor Data Cloud, you can use the Circulor Data Cloud Registry (‘Registry’) to view the online segments Circulor has associated with your device. By accessing this Registry, you can view the types of third-party interest segments that are available for Circulor Data Cloud customers. Please note that the interest segments you see within the Registry is information from the profile associated with the specific browser, computer or device that you are using to visit the Registry. You may see different segments when viewing the Registry from a different browser, computer or device. For a complete picture of the segments associated with all of your browsers and devices, we therefore recommend using these different browsers and devices when accessing the Registry.

For a copy of your offline information, please contact the Circulor Global Data Protection Officer as set out in Section 16 below. While the majority of offline access requests can be handled quickly, complex requests may take more research and time.

We cannot provide offline first-party information that is collected and maintained by our customers. If you have questions in regards to first-party information, Circulor recommends that you contact directly the company that collected it from you.
