1.) Where the personal data we process comes from

We collect personal data directly from individuals via our CCS Survey – see our Lifestyle Survey Privacy Notice here for more information on this collection and processing.

We utilise personal data from third party sources including data brokers, data aggregators, publishers and data partner service providers.

Where personal data is shared with a third party, this will be deleted as soon as an activation is complete. As indicated in section 10 of this Notice, you can request that we delete personal data we have associated with you, however we may continue to receive personal data about you after we have processed your deletion request.

2.) Types of personal data we may process about you in connection with our Identity Products

We may process various types of personal information as a controller as part of some of our Identity Products Note other personal data may be relevant to the processing of some of these Identity Products, but we do not process this personal data in our role as data controller and therefore it is not covered in this privacy notice.  These may include the following:

(a) Data we received through your participation in the CCS survey. This includes:

  • Information contained within the responses you give These will include your demographics, attitudes and interests. The Survey asks for your opinions, interests, hobbies; views on products and services items you own and buy; your age; occupation; income; lifestyle; media usage; views on marketing and advertising; and other information that is useful for describing different types of people. Your responses in relation to questions about your race, ethnicity, sexual orientation and religious or philosophical beliefs, your health, political opinions or trade union membership (“special category personal data”). It is up to you whether you provide this special category personal data when completing the Survey and you will be provided with a “prefer not to say” or a “neither agree/nor disagree” style answer to choose from.   We do not use this information to knowingly target you with marketing and advertising;
  • Your contact details where you have explicitly consented to these being shared with us.
  • Cookie data, where the survey drops cookies and you have consented to this being shared with us.

(b) Data we receive or utilise from third parties:

  • Online identifiers, internet and Network Activity Information, including internet protocol (IP) address used to connect your computer to the internet, mobile device IDs, cookie IDs, Mobile Advertising IDs, websites that you visit and how you interact with those websites and any apps you may use. We may also receive information about your browsing habits across multiple websites and over time. We may also receive information about your interaction with emails or other electronic messages we send you, such as when you open or click on an email.
  • Location Information, we may infer a location based on your IP address and collect from third parties other geolocation information.
  • Third party data, meaning the data we utilise in the platforms of our activation partners such as meta IDs. Note, we do not process this data as a controller.
  • Education Information, like your level of education and what institutions you may have attended.
  • Financial such as indicators of income and wealth, such as individual and household annual income ranges, likelihood of savings and investments, and presence of credit accounts.
  • Family / Household data (such as number of adults/children, multi-generational household, etc.). We do not knowingly receive information from individuals under 16, but we may receive information about how many children are in your household and their year of birth or age range.
  • Professional and Employment Related Information, we may also collect information about your employment such as job and title, as well as your income level.

3.) How we use your personal data

(a) General Purposes

  • We may use information to analyse and improve our products and services. For example, we may use your information to make our websites, apps, services, and products better. We might use your information to customise your experience to conduct research and analysis.
  • We use information to administer our services and products, and for internal operations. For example, we use personal data for troubleshooting, data analysis, and testing.
  • We use information for security purposes. For example, we may use personal data to protect our company, our clients, and our business partners. We also may use personal data to protect our websites or our services, as well as to detect and investigate activities that may be illegal or prohibited (such as cyber attacks or fraudulent transactions).
  • We use information to respond to your requests or questions. We use information to contact you in response to your feedback or other matters related to our relationship with you (such as about this Notice).
  • We use information for verification purposes. For example, we will use certain pieces of personal data to verify your identity if you make requests pursuant to this Notice. The verification steps and the pieces of personal data that we request may vary depending on the sensitivity and nature of your request.
  • We use information as otherwise disclosed or permitted by law, or as we may notify you. We may use personal data to create deidentified or aggregated data which does not identify you or any other individual. We may use and disclose this anonymous or aggregated data as we choose.

(b) Research and Insights

  •  We use personal data, including combined, matched or enriched data, to generate marketing insights. For example, to determine what proportion of a population might be interested in a particular product. We provide marketing insights information to our clients on things such as the potential size of a particular market and which traits are most likely to be interested in a particular product or service. Clients can use this information to target relevant people with advertising.
  • We use your information to assess the effectiveness of client advertising and marketing campaigns.

(c) Deterministic Modelling

  • To create Lookalike audiences through creating a ‘seed’ audience and then using that audience to find lookalikes across another platform.
  • We use personal data to create advertising "segments”, for instance: "men living in a particular postcode area who are aged between 20 and 30". These segments are used by our clients to deliver targeted advertising.

(d) Attribution Modelling utilising personal data

  • We combine or match personal data received from data partners including Zeotap with other data (for example, data coming from our Lifestyle Survey - see Privacy Notice) and enrich it. This combining, matching and enrichment process helps us select the most appropriate group of people for our clients’ advertising or marketing campaigns. We also conduct analytics and profiling that includes predicting people's purchasing behaviour, likelihood of response to marketing or purchase of a product, brand loyalty, product and brand affinities and preferences. This may involve probabilistic matching e.g. individuals who like puppies in London are also likely to like dog products. This process is sometimes also referred to as ‘attribute modelling’. 
  • We use personal data to create advertising "segments”, for instance: "men living in a particular postcode area who are aged between 20 and 30". These segments are used by our clients to deliver targeted advertising.

(e) Attribution Modelling not using personal data

  • We don’t use any personal data for this.

4.) How we share your personal data

We share your personal data with vendors and service providers who perform services on our behalf. We may share personal data with vendors who assist us with the uses of personal data described in this Notice.

We share your personal data with social media platforms and publishers. We may share your personal data with social media platforms such as Meta and publishers who allow us to buy advertising space for our clients.

We will share your personal data if we think we have to in order to comply with the law or to protect ourselves, our clients and others. We may share any or all categories of personal data to respond to a court order or subpoena.

We may also share your personal data if there is a similar change to our corporate structure. We may also share your information with others as part of certain due diligence processes. We also share information for the purpose of management and administration of our business.

We will only transfer your personal data outside the market in which you are located where we are satisfied that adequate levels of protection are in place to protect the integrity and security of any personal data being processed and in compliance with applicable privacy and data protection laws.

8.) How long we keep your personal data

We will keep your personal data for as long as is necessary for the purposes described in section 2, and in accordance with our legal obligations. After this time, your personal data will either be securely deleted or anonymised so that it can be used for analytical purposes.

9.) How we protect your personal data

Our safeguards include robust systems and processes designed to ensure that we collect only the minimum personal data necessary to pursue the purposes for which we process your personal data, and that only those who need to view your personal data can see it.
