We believe that data protection is essential to the growth and prosperity of the Internet and that a personalised experience online can provide significant benefits to users if done properly. In accordance with these believes, Epsilon creates results for advertisers in revolutionary ways without compromising users’ privacy or data protection.
While you visit digital properties, such as websites and mobile applications, there are almost always third-parties working behind the scenes to help provide you with a great digital experience. These companies provide services such as analytics, advertising and fraud prevention for retailers, publishers, and other organisations. Epsilon is one of these companies and we help provide the advertising that keeps your favourite blogs free, your favourite stores in business, and your advertising experience more relevant.
Epsilon provides its clients with digital advertising and personalised content across the Internet. To make some of these things possible, and to make smarter decisions, we need to use information that is considered Personal Data.
We also use our technology to provide life-saving messages, geotargeted to individuals in affected areas, during tornadoes and AMBER Alerts. To learn more about these internationally recognised programs established by Epsilon through an organisation called the Federation for Internet Alerts, click here.
The Interactive Advertising Bureau in Europe (“IAB EU”) launched its Transparency and Consent Framework (“TCF”) in April 2018. The TCF is an industry tool that supports companies within the digital advertising ecosystem to manage their compliance obligations under Data Protection Laws, and it provides a standardised way to provide notice and choice across the Internet. You can read more about the TCF here.
Epsilon participates in the IAB EU’s TCF and complies with its specifications and policies. Epsilon’s identification number as a vendor within the TCF is 24. Epsilon also operates a Consent Management Platform (“CMP”) connected to the IAB EU’s TCF with identification number 23.
However, certain essential Cookies do not require your consent. This includes Cookies that are essential to comply with the GDPR’s security principle as well as Cookies that help ensure that content of a page loads quickly and effectively by distributing the workload across numerous computers.
Epsilon uses Tags and Cookies to collect Pseudonymous Personal Data about the browser or device you are using, including Visitor Data and information about your browsing behaviour, such as what digital properties that you have visited and online transactions that you have made. This type of Pseudonymous Personal Data is processed whenever you visit digital properties and open emails where our Tags are implemented, including digital properties belonging to our clients and partners such as high street retailers.
We are a part of the digital advertising ecosystem and involved in activities such as Real-Time-Bidding (“RTB”). RTB is a set of technologies and practices used in programmatic advertising that enables advertisers to compete for available digital advertising space and place online adverts on digital properties by automated means. RTB allows for certain information to be sent to participants of the digital advertising ecosystem in Bid Requests. Bid Requests normally contain information that constitutes Personal Data, such a Visitor Data. This information is used by participants to evaluate the bid opportunity and respond with a bid price to serve an advert on the digital property. We only process Pseudonymised Personal Data that we receive in Bid Requests.
We also perform Cookie syncs with advertising exchanges and other partners, such as Eyeota, which means that we receive and share Cookie IDs with each other. This enables us to recognise information about the user and determine whether we want to respond to a Bid Request or not.
All location data we process is limited to non-precise location data (as defined by IAB EU’s TCF).
Some of our clients provide Direct Identifiable Personal Data such as name, address, email address and associated transactional information, to us. We also receive Direct Identifiable Personal Data from third-party partners we contract with. These partners, including CACI, provide us with name, address and profiled attributes. The source of the name and address information provided by CACI is the edited Electoral Register. You can read more about how CACI collects and processes your Personal Data here. CACI is not an Affiliate of ours and we have no control over its data practices.

Technically deliver ads or content
Receiving and sending information about and to your device such as device type and capabilities that allows you to see and interact with advertising and content delivered, e.g. to deliver the right size advertisement creative or video file in a format supported by the device.
In support of one or more of the purposes set out above we may use Personal Data that we hold to determine whether different devices are likely to belong to you or your household and to try and distinguish your device from other devices based on information it automatically sends, such as IP address or browser type. This helps us develop a predictive profile of your interests across these different devices, including making sure we do not show you the same advert too often.
Offline Data we receive from our clients and partners will, before it is pseudonymised, be processed based on legitimate interest for receiving and storing purposes and to create a profile. We will only combine (pseudonymised) Offline Data related to you with other Pseudonymous Personal Data that we hold and process it for the above purposes if you have given us your prior consent. (Pseudonymised) Offline Data can be combined with your online activity in support of one or more purposes set out above.
Epsilon’s legitimate interests for the purposes of (i) receiving and storing Offline Data; (ii) ensuring security, prevent fraud and debug; and (iii) for technically deliver ads or content include, providing our Services and ensuring that our clients are only paying for advertising that is viewed by a natural person (e.g. not a bot). Further information can be provided upon request.
We sometimes engage social media platforms to display direct marketing to you on their platform. We use “list-based” and “look-a-like” tools to do this. Using list-based tools involves the uploading of Personal Data to the social media platform in question (such as a list of email addresses). The platform then matches the uploaded Personal Data with its own user base. Any user that matches the uploaded list is added into a group that will be sent the selected marketing message. Look-a-like tools offer the ability to build other audiences based on the characteristics of an original audience that was created using a list-based tool. These audiences generally comprise of users that have not previously engaged, but who look like the list-based audience (i.e., they are users with similar interests, behaviours or characteristics). When creating this sort of audience, the social media platform uses Personal Data it has about other users of its platform to find users who match the interests and behaviours of users that are current customers. Examples include Facebook Custom Audiences or LinkedIn Contact Targeting. We will not undertake this processing unless you have provided us with consent for the purposes set out above, and we have contractual controls in place to ensure that the social media platform can only use the Personal Data we share to enable the provision of the Services. We are not responsible for the data practices of social media platforms and recommend you read their own privacy policies.
We share your Personal Data:
- With our Affiliates and processors that assist us in providing our Services.
- With our clients. For example, we may share Personal Data collected by Tags on our clients’ digital properties to help our clients learn more about their visitors, and Personal Data collected when an advert is delivered to report on the performance of advertising and to help clients understand how often they are serving an advert to the same individual and to help them optimise.
- With participants of the advertising ecosystem such as advertisers, publishers, advertising exchanges, data management platforms, demand side platforms and supply side platforms, to be able to participate in RTB activities.
- With the Abacus Alliance UK, which is a cooperative operated by another part of Epsilon. Personal Data will be used by Abacus Alliance UK to provide participating clients with better insight into their customers and assess, for example, whether an individual should be included on a mailing list for a specific postal marketing campaign. More information about how the Abacus Alliance UK processes your Personal Data and how to exercise any rights can be found here.
- With social media platforms as described above.
- Third-parties in the event of any reorganisation, merger, sale, joint venture, assignment, transfer or other disposition of all or any portion of our business, assets or stocks (including in connection with any bankruptcy or similar proceedings).
- As we believe necessary and appropriate: (a) under applicable law; (b) to comply with legal processes and obligations; (c) to respond to requests from public and governmental authorities including public and government authorities outside your country of residence; (d) to enforce our terms and conditions; (e) to protect our operations; (f) to protect our rights, privacy, safety or property; and (g) to allow us to pursue available remedies or limit the damages that we may sustain.
We retain all Personal Data in accordance with our data retention policy which abides by applicable law. The retention period depends on the type of data. For example, we retain non-transactional Pseudonymous Personal Data we collect or receive online or through Bid Requests for no more than eighteen (18) months.
In situations when we rely on consent to process your Personal Data you have the right to withdraw your consent at any time. You can do that via the “Review Consent Preferences” in the footer of our website or via any CMP connected to the IAB EU’s TCF. A CMP will usually pop up on an EU/UK website you have not visited before that partners with advertising companies to provide you with personalised advertising and a better digital experience. Withdrawing your consent in this way will apply only on the website/app you are visiting. If you want to withdraw your consent to Epsilon across the internet, please visit our browser and device based tool here and our email based tool here.
We understand that you may be interested to know what Personal Data we hold about you and which advertising interest segments we believe to be connected to you (access). You can view this information and even delete it if you choose to do so by clicking here.
If you wish to exercise any other rights you might under Data Protection Laws (including rectification, portability and restriction), please Contact Us.
In order to provide our Services, we transfer Personal Data to, and Process Personal Data in, countries outside the European Union (EU), the European Economic Area (EEA) and the United Kingdom. More specifically our servers are located in Ireland, Netherlands, Singapore and the United States, and our processors operate around the world including the United States and India.
We have taken appropriate and suitable safeguards to ensure that your Personal Data will remain protected when transferred outside EU/EEA and the United Kingdom. This includes implementing Standard Contractual Clauses for transfers of Personal Data adopted by the European Commission and/or the United Kingdom. Further information about our international transfers as well as the safeguards in place can be provided upon request.
We have implemented appropriate technical and organisational security measures to protect the Personal Data in our care, both during transmission and once we receive it. This includes physical and technical security measures to protect our Personal Data from accidental or unlawful destruction, loss, or alteration, and from unauthorised disclosure or access. Although, please note that no method of transmitting information over the Internet or storing information is completely secure.
Our industry has a rigorous voluntary self-regulatory regime, and we are active members of industry groups such as the Interactive Advertising Bureau (IAB), Interactive Advertising Bureau Europe (IAB EU), Interactive Advertising Bureau UK (IAB UK), Digital Advertising Alliance (DAA), European Digital Advertising Alliance (EDAA) and Digital Advertising Alliance of Canada (DAAC). These groups promulgate codes of conduct and principles that impose requirements on participating members such as transparency and choice around the use of Personal Data for interest-based advertising, and some even require regular audits of member privacy practices. Such codes and principles include the DAA Self-Regulatory Principles, the EDAA Self-Regulatory Principles, and the DAAC Self-Regulatory Principles, which we all support.
Our Data Protection Officer is tasked with informing and advising us on the obligations that apply to us under Data Protection Laws, as well as monitoring our compliance with the same. If you need to contact our Data Protection Officer, please email us here. However, we respectfully ask that you only contact our Data Protection Officer regarding urgent matters relating to data protection.
As an EU resident, you have the right to report a concern to your country’s Data Protection Authority. UK residents can report a concern to the Information Commissioner’s Office. However, we respectfully request that you contact us first so that we can assist you.
