Criteo specializes in creating personalized advertisements. We work with online partners to build advertisements for users who visit their website or mobile applications and with publishers to display personalized advertisements.
Our aim is to deliver advertisements by displaying products and/or personalized banners that you might be interested in, based on your recent browsing behavior. For example, if you visit and browse on Website/mobile application A, on a subsequent online visit to Website/mobile application B, you will see ads personalized by your browsing history on Website/mobile application A.
With our service, you should receive personalized ads that are more relevant for you than the standard advertising you would receive without Criteo. Click here for more information on Interest Based Advertising.

We collect information via technical cookies placed on your browser.
Criteo “tags” visitors to its partners’ websites with browser cookies. Users tagged by Criteo are given a technical identifier. At no point does Criteo collect identifying personal data such as your name or address.
The browser cookies track the products viewed by the visitor and pages visited of the partner for whom Criteo is delivering ads. Pixel tags are used by Criteo to transfer browsing data from visitors of our partner's websites to Criteo's servers.
What are cookies? A cookie is a small text file stored on a user’s computer for record-keeping purposes. There are two types of cookies:
What are pixel tags? A pixel tag (also commonly known as a web beacon) is an industry-standard, often-transparent graphic image usually no larger than a 1x1 pixel that is placed in a website.
Our partners’ advertisements are displayed on many websites, also known as “publishers.” These publishers may also place cookies on your browser. These cookies are there so that the publishers recognize that Criteo has a personalized advertisement available for your browser.
In environments that do not support cookies, like mobile applications, we may use other similar technologies for the same purpose of cookies. To serve our ads in mobile applications we collect identifiers, such as Google Advertising ID or Apple IDFA depending on the operating system of your mobile device. These identifiers consist in a string of technical and random characters singling out your device that Criteo stored by Criteo with a hash (non-reversible encrypting method).
To serve you our personalized advertisements and provide a seamless online experience, we may link your identifiers on the different environments you are using (“ID syncing”). At no point we collect identifying personal data such as your name or address to operate the linking. We use exact linking methods by leveraging the technical data collected through our technology such as our advertising partner’s identifiers or email hash that they may pass to us. See data collection paragraph to learn more.
We do not know who you are. We collect and use technical data relating to your browsing navigation to display personalized advertisements.
In order to serve you advertisements that are the more relevant to your interests, we collect data related to your browsing activity through cookies or equivalent identifiers that record:
We also collect technical user identifiers from our advertising partners for the purpose of linking the different browsers and mobile apps you use and serve you relevant ads based on your behaviour across environments (“ID syncing”). For that purpose we process and store
Finally, we can collect technical identifiers from third parties for the purpose of improving our ID syncing and be sure to offer you a seamless online experience. These trusted partners commit to only share ID corresponding to deterministic linking made between cookies and/or mobile identifiers and to provide an efficient choice mechanism to end users (opt-out). For eg : the linking information sourced from our partners could be Cookie ID ABC = Apple IDFA 123 = MD5 hashed value).
We do not know who you are. We do not know your address, your place of work, your date of birth, your email address, your phone number. We do not use or store your IP address for targeting purposes*.
We do not collect hardware-based identifiers such as UDID, Mac Address.
We do not collect sensitive information (such as religion, political opinion, health…).
We collect this information in order to increase the relevancy of the ads being displayed to you.
The data we collect is also used for reporting purposes, and to give our clients and partners more information about the performance of their advertising campaigns, and to improve performance over time.
We do not create segments to specifically target children under 13 years old.
We do not process any information which could be used by Criteo, directly or indirectly, with the help of a third party or otherwise, to determine the personal identity of users.
We share information collected with our subsidiaries or affiliated companies. We share aggregated data with our partners, i.e. data that does not permit identification of a partner, or permit you to be identified. We share non-aggregated data only upon approval of our partners and in compliance with our commercial agreements.
