1. About AdRoll Group's Services

Back to top

AdRoll Group provides targeted advertising and marketing services for our clients (“Clients” or “Advertisers”). The AdRoll Group website(s) are a collection of sites that we use to describe our services to potential advertiser clients, to provide our advertising services to these Clients, and to support Clients and partners as they seek to deploy and manage their campaigns with us over time.

Our products help show our Clients’ ads and emails to the people that are most likely to find them interesting. We aim to make advertising more useful and relevant to consumers by showing ads that are best tied to their specific interests. And we show these ads on websites which rely on advertising revenue to support the content we all consume each day.

To do this, when you visit a website or a mobile application operated by AdRoll Group or an Advertiser (collectively, “Digital Properties”), open an email from AdRoll Group or an Advertiser, or we serve you an ad on behalf of an Advertiser on a third party site, we may collect some or all of the data described in our Services Privacy Notice. Our platform uses that data, as well as other data described below, to help Advertisers provide ads to you that are more relevant to you.

For example, let’s say you just joined a local soccer club and are in the market for a new soccer ball. If you visit ACME Soccer Ball Co.’s website in search of the perfect soccer ball, but don’t purchase one just yet because you are still looking, we may later show you ACME Soccer Ball Co. ads to encourage you to come back and purchase one of their soccer balls, perhaps even with a discount offer or notice of an upcoming sale. We may also show you ads from ACME Soccer Ball Co. or other companies with additional product recommendations you may be interested in, such as for soccer cleats, or tickets to an upcoming soccer match, as you browse the internet. If you gave ACME Soccer Ball Co. your email address for marketing purposes, we may also serve ACME Soccer Ball Co. ads to you through other channels, such as by email.

2. What Data We Collect

Back to top

We may collect the following categories of information on our website and use them for the purposes explained below.

  • Contact Information:You may provide us with your name, address, phone number and email when you set up an account with us and you may provide your name, title, company, email, address and/or phone number when you sign up for an event with us online or download content from our site.
  • Account Information:If you open an account, we will collect your username and password and other information necessary to open and access your account.
  • Customer Service Information:Information you may provide to customer service including your email address for purposes of responding to your inquiries and survey responses.
  • Financial Information:Credit card number or other payment account information. This information is collected directly by our payments processor and not stored at AdRoll.
  • Activity on Our Digital Properties:This is data about your browsing activity on our websites, or when you interact with our other tools or dashboards. For example, which pages you visited and when, what items were clicked on a page, how much time was spent on a page, whether you downloaded a white paper.
  • Device and browser information:This is technical information about the device or browser you use to access our Digital Property. For example, your device's IP address, cookie string data, operating system, and (in the case of mobile devices) your device type, and mobile device's identifier (such as the Apple IDFA or Android Advertising ID, and any other unique identifier that may be assigned to the mobile device).
  • Ad data:This is data about the online ads we have served (or attempted to serve) to you. It includes things like how many times an ad has been served to you, what page the ad appeared on, and whether you clicked on or otherwise interacted with the ad.
  • Data from Advertising Partners:This is data that we lawfully receive from other digital advertising companies that we work with (“Advertising Partners”) to help us deliver ads to you and recognize you across browsers and devices. This may include pseudonymous advertiser identifiers (meaning identifiers that help identify your browser or device, but do not directly identify you as a person) which some third party Advertising Platforms choose to share with us – for example, an identifier (such as a cookie) associated with a hashed version of your email address, or demographic data such as age range. We may work with our Advertising Partners to synchronize their unique, pseudonymous identifiers to our own to enable us to more accurately recognise a particular unique browser or device and the advertising interests associated with it.
  • Hashed email addresses:We collect hashed versions of the emails you enter on our site. Hashing is a “one-way function” that effectively pseudonymizes email addresses. For instance, when is run through a typical hashing function, it becomes the following string of digits: 0F0B7B1A1A7E8BDBBC6AA545F8CCD6F83671B32479271BFCB6CC8498912058D5. We take this step to de-identify data and protect email addresses, while being able to use an identifier to better connect devices and browsers. We describe how this helps us better provide our services in “How we use the data we collect”
  • Contact Information.We obtain and collect contact information from various third party sources, including from public sources and through licenses with data providers. We may also infer contact information based on email addresses and email naming conventions. This contact information is B2B information – in other words, it is usually the contact information of someone at a business email address, business street address, or sometimes, a business telephone number. We will not collect contact information this way for individuals who are located in European Territories.
  • Third party information:We may collect additional information about you from other third party sources where they have the rights to share such information and we have the rights to use it, for example, demographic data or title and employer data. We use this data to better understand our customers and to better market our services to you.

3. How We Use the Data We Collect

Back to top

We use this data to operate our business and provide services to you as well to personalize AdRoll Group advertising and marketing materials we may serve to you:

  • Providing our AdRoll Services and Customer Support:For example, to monitor usage of features, manage campaigns, and log data for audit purposes. We may contact you when you ask us for support or when it appears to us that you might need support, and to maintain records of our communications with you for future reference.
  • Invoice you and collect fees for services we have provided.
  • Troubleshoot Problems:To monitor and fix our website performance, for example if the site is slow, not loading properly, or to investigate aberrations in performance of our services.
  • Prevent potential fraud and enforce our Terms of Service.To prevent fraud on our site or through the use of our services; to enforce our Terms of Service or other policies or investigate any potential violation of those Terms and policies, any potential violation of the law; or to protect ourselves, our customers, or any third party from any potential harm (whether tangible or intangible).
  • Customize, measure and improve our website and services:To provide customized content and to measure which content is most helpful (or unhelpful) to our customers, which helps improve our website and our services. For example, if we notice higher visits to certain Help Center articles or receive higher Customer Support tickets for specific issues, we can improve our support materials or identify areas where we can make our product better for our customers.
  • Contact you about your account or our services, including to market our services to you or provide updates:We may use your contact information to contact you about your account, for example, in relation to performance of your campaigns, to follow up on billing issues, or to tell you about new services we are offering. We may send you product updates, performance information, surveys, or communicate with you in other ways about our services. When we can legally do so, we may augment the information you give us in order to contact you by phone or even snail mail. You can opt-out of receiving emails by unsubscribing through the link at the bottom of our emails or by updating your email preferences here. You can let us know if you don’t want to receive phone calls or other marketing materials from us by contacting
  • Deliver Targeted Marketing:We use our own AdRoll Group services to generate and route marketing leads for our business and to deliver targeted marketing to you. For more information about how our services work, please see our Services Privacy Notice.
  • Targeting:Selecting ads that are more likely to be relevant to you on other sites around the net based on the interests previously associated with your device and the time of day you may be most interested in viewing these specific ads. For example, we may show you ads for an AdRoll Group product on another site related to a whitepaper you downloaded from one of our websites (or similar sites we think you may like) during lunch or commute hours.
  • Frequency capping:Making sure that you don't see the same ad too many times.
  • Sequencing:If you are being served a sequence of ads, making sure we show you the right ad next in the sequence.
  • Cross-device matching:Identifying all devices that are likely to be associated with you so that ads can be targeted, capped and sequenced across those devices. For example, cross-device matching helps us NOT show you ads for the AdRoll Group services you were looking at on your phone but that you already signed up for on your laptop. Instead we’ll try to show you ads for our newly launched feature or product that can help your business dare to grow even more. It also helps us match devices so we can honor your opt-out choices across all devices we know are connected to the opted-out cookie.
  • Attribution:Monitoring when, where, and at what price we served certain ads so that we can measure our influence on the marketing result of the Advertiser’s campaigns and overall marketing strategy. For example, being able to measure if a certain ad campaign (the ads shown and to whom they were shown) actually led to a potential customer becoming a paying customer.
  • Reporting:Analyze how our ads are performing and gain insights into our customers. Reporting may include ad metrics such as impressions, clicks, and conversions (for example, if you create an AdRoll Group account or download a white paper from our site). This helps us identify ads that are useful to our customers and demonstrate AdRoll Group’s value, and relatedly, helps us identify an ad that is not performing well (customers aren’t clicking on it), we will be able to see that data and update our ad or ad campaign strategy.

4. Our Legal Basis for Processing Personal Data (European Territory Visitors only)

Back to top

We provide the representations and information in this Section 4 in compliance with European privacy laws, in particular the European General Data Protection Regulation (GDPR). If you are a visitor from the European Territories, our legal basis for collecting and using the personal data described above will depend on the personal information concerned and the specific context in which we collect it. "European Territories" mean the European Economic Area and Switzerland. For the purpose of this Privacy Notice, the term "European Territories" shall continue to include the United Kingdom, even after the United Kingdom leaves the European Economic Area following Brexit.

We will normally collect personal data from you where the processing is in our legitimate interests. For example, to administer our platforms and services and fulfil our contractual obligations as a service provider. In some cases we may collect and process personal data based on consent.

If you have questions about or need further information concerning the legal basis on which we collect and use your personal information, including if you would like to better understand how our legitimate interests to process your data are balanced against your data protection rights and freedoms, then please contact us using the contact details provided under the “Contact Us” heading below.

Back to top

We may disclose information about you:

  • With our service providers:We contract with companies who help with parts of our business operations (e.g., for example, website and data hosting, fraud prevention, viewability reporting, data hygiene, marketing, and email delivery), as well as billing, collections, tech, customer and operational support.
  • With our subsidiaries and related companies:But they will only process your data for the purposes already explained in this Privacy Notice. Our subsidiaries are AdRoll Advertising Limited (Ireland), AdRoll Holdings Limited (Ireland), AdRoll Limited (UK), and AdRoll Pty Limited (Australia).
  • With other advertising companies in the digital advertising ecosystem.We share hashed email addresses (or other pseudonymous identifiers associated with those hashes), technical data that we collect about your browsing habits and your device (such as data relating to our cookies, tracking pixels and similar technologies) with other advertising companies in the digital advertising ecosystem. This enables them and us to better target ads to you.
  • In connection with legal proceedings:When we are under a legal obligation to do so, for example to comply with a binding order of a court, or where disclosure is necessary to exercise, establish or defend the legal rights of AdRoll Group, our Advertisers or any other third party.
  • To comply with legal process:To satisfy in good faith any applicable law, legal process, or proper governmental request, such as to respond to a subpoena (whether civil or criminal) or similar process.
  • To investigate wrongdoing and protect ourselves or third parties:To enforce our Terms of Service or other policies or investigate any potential violation of those Terms and policies, any potential violation of the law, or to protect ourselves, our customers, or any third party from any potential harm (whether tangible or intangible).
  • In connection with a sale of our business:If a third party acquires some or all of our business or assets, we may disclose your information in connection with the sale (including during due diligence in preparation for the sale).
  • Finally, we may disclose aggregated, anonymized information to third parties, for example, when we conduct industry wide surveys to publish benchmark reporks, or to include statistics when collaborating with researchers or other companies on industry white papers.

6. Cookies and Related Technologies

Back to top

Our websites use cookies, tracking pixels and related technologies to operate and personalize our site, for example to provide personalized content on our site, enable customer service chat functionality, for analytics purposes, and to target ads to you about our products and services on other websites.

AdRoll Group uses cookies, tracking pixels and related technologies to provide our services for Advertisers. Cookies are small data files that are served by our platform and stored on your device.

Tracking cookies enable us to identify your device when you move between different Digital Properties, so that we can serve targeted advertising to you.

  • Specifically, the AdRoll cookie we serve through the AdRoll platform for this purpose is named “__adroll” and “__adroll_fpc”.

Our Advertising Partners may also drop cookies for the purposes described above. For example, cookies are dropped for the exchanges through which we buy ads, such as AppNexus and Rubicon and for analytics tools such as Pixalate which helps us measure viewability (meaning whether the ad was actually served and seen) and prevent fraud.

Generally, the type of cookies dropped will vary depending on the Advertising Partner. We provide a list of our Advertising Pixel Partners here.

Additionally, we use non-tracking cookies (not unique) to store user decisions in terms of your ad consent and opt-out choices:

  • We may drop an __adroll cookie with value opt-out if you opt-out as described below and an AdRoll consent cookie to track your consent choices.
  • We may drop a __consent cookie that stores the consent choices you have made regarding data processing and advertising by AdRoll.

A full list of AdRoll Group cookies is set out below:

Tracking cookies

Non-tracking cookies



To get more information about the individual cookies dropped by our website, please or the “Adjust Ad Preferences” link on the footer of our website or in our cookie consent banner.

7. Your Choices and Opting-Out

Back to top

We recognize how important your online privacy is to you, so we offer the following options for controlling the targeted ads (sometimes called “interest-based ads”) you receive and how we use your data.

Opting-out of this type of advertising through the below methods will not prevent you from seeing ads, but those ads will likely be less relevant because they will not be tailored to your interests. The ads might, for instance, be randomly generated or based on the web page you are visiting.

  • Web browser:You can opt-out of receiving personalized ads (including retargeted ads) served by us or on our behalf by clicking on the blue icon that typically appears in the corner of the ads we serve and following the instructions provided or by clicking here. Please note that this “opt-out” function is browser-specific and relies on an “opt-out cookie”, thus, if you delete your cookies or upgrade your browser after having opted out, you will need to opt-out again. If you use a Safari browser, please also see directions regarding our cookie-less technology opt-out, below.
  • Cross Device Opt-Out:In some cases we may link multiple browsers or devices to you. If you opt-out on a browser or device and we have more linked to you, we will extend your opt-out decision to the other linked browsers and devices. Since we only link users across browsers and devices in some conditions, there could be cases where you are still being tracked in a different browser or device we have not linked, and where we are treating you as a different user.
  • Mobile Device Opt-Out:To opt-out of receiving targeted ads that are based on your behavior across different mobile applications follow the below instructions, for iOS and Android devices:
    • iOS 7 or Higher:Go to your Settings > Select Privacy > Select Advertising > Enable the “Limit Ad Tracking” setting; and
    • For Android devices with OS 2.2 or higher and Google Play Services version 4.0 or higher:Open your Google Settings app > Select Ads > Enable “Opt out of interest-based advertising”.
  • Industry Opt-Out Tools and Self-Regulation:
    • AdRoll Group is a member of the Network Advertising Initiative (NAI) and adheres to the NAI Code of Conduct. You may use the NAI opt-out tool here, which will allow you to opt-out of seeing personalized ads from us and from other NAI approved member companies.
    • We also comply with the Self-Regulatory Principles for Online Behavioral Advertising as managed by the Digital Advertising Alliance (DAA). You may opt-out of receiving personalized ads from other companies that perform ad targeting services, including some that we may work with as Advertising Partners via the DAA website here.
    • We also comply with the Canadian Self-regulatory Principles for Online Behavioral Advertising as managed by the Digital Advertising Alliance of Canada (DAAC). You may opt-out of receiving personalized ads from other companies that perform ad targeting services, including some that we may work with as Advertising Partners via the DAAC website here.
    • Finally, we also adhere to the European Interactive Advertising Digital Alliance (EDAA) guidelines for online advertising and you may opt-out via their ”Your Online Choices” website here.

You can also request that we stop email marketing to you. You can use the unsubscribe link in our marketing emails or contact

8. Data retention

Back to top

We retain data for as long as necessary to provide our services and for the purposes described in this Privacy Notice. For example, we may retain billing information as necessary to meet audit requirements. We may retain login information to confirm when Terms of Service were accepted. We may also retain information as long as necessary to meet legal requirements, resolve disputes or enforce agreements.

We retain cookie data such as device and browser information, ad data, and data collected on our Digital Properties as follows:

Mobile Identifiers and Cookie Identifiers: Cookie identifiers we collect expire (and are then deleted) 13 months from the last time your device accessed a Digital Property using our technology. If you visit another Digital Property that uses our technology inside that 13-month expiry period, then the expiry period will be reset and measured from that date instead. The expiration period for mobile identifiers is controlled by the end-user on their own device.

Personal Data Associated with Mobile and Cookie Identifiers Related to Browsing History: We delete personal data associated with mobile and cookie identifiers after 12 months. For example, data such as an Advertiser’s website you visited or ads that you may have clicked.

Personal Data Associated with Real Time Bids: Data logged for a particular submitted bid or a received real time bid request (including cookie identifiers, mobile identifiers, the advertisable bid on, and the advertisable won or displayed to the end-user) are deleted after 30 days.

Personal Data Associated with the Display of an Advertisable: Data logged for the display of an advertisable (including cookie identifiers, the advertisable won or displayed to the end user as well as data indicated whether an end user clicked on the particular advertisable displayed) are deleted after 12 months.

9. Security

Back to top

We apply technical, administrative and organizational security measures to protect the data we collect against accidental or unlawful destruction and loss, alteration, unauthorized disclosure or access, in particular where the processing involves the transmission of data over a network, and against other unlawful forms of processing.

10. International transfers

Back to top

We may transfer the information we collect about you to countries (including the United States of America) other than the country where we originally collected it for the purposes of storage and processing of data and operating our services. In general, these countries will be the countries in which we, our Advertisers, or our or their service providers operate.

Those countries may not have the same data protection laws as your country. However, when we transfer your information to other countries, we will protect that information as described in this Privacy Notice and take steps, where necessary, to ensure that international transfers comply with applicable laws.

For example, when we transfer your information from a European Territory to our parent company in the United States, we do so under the European Commission's Standard Contractual Clauses.
