Privacy Policy

Privacy Policy

Criteo takes your privacy very seriously. This privacy policy governs and details the main privacy principles we apply to the data we collect through our services.

To access our privacy policy governing our corporate website only please click here.

1. About Criteo’s services 

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.

3. Our Technology

Dynamic Retargeting                                                    

We collect information via tracking cookies placed on your browser or advertising IDs in environments that do not support cookies like mobile applications.

Thanks to these technologies, Criteo “tags” visitors to its partners’ websites and mobile applications. Users tagged by Criteo are given a technical identifier. At no point does Criteo collect identifying personal data such as your name or address. Criteo only analyses the products viewed by the visitor and pages visited of the partner for whom Criteo is delivering ads.

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. Their use are governed by the specific privacy policies of the publishers which can be accessed directly from their websites.

Cross-device Linking

To serve you our personalized advertisements and provide users with a seamless online experience, we may link your identifiers on the different browsers and environments you are using (“ID syncing”). Thanks to its ID-syncing technology, Criteo is able to serve you the most relevant ads disregarding the device or browser you are currently using without collecting or processing any identifying personal data such as your name or address to operate the linking. For this purpose, Criteo uses 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. We may also receive ID-syncing information from trusted partners using diverse linking methods for the same purpose and with the same level of guarantees in terms of Privacy and Data Protection. See “data collection and use” paragraph to learn more.

4. Data Collection and Use

We do not know who you are. We only collect and use technical data relating to your browsing navigation to display personalized advertisements.

We collect browsing information

Data collected on Criteo network

To serve relevant ads, we have to be able to single out patterns but we never willingly store data that would allow identification of a person (such as name, surname, phone number, address, etc.). We collect data related to your browsing activity through cookies or advertising IDs that record:

-          events related to your activity on our advertising partner’s website (such as the number of pages viewed, the products you viewed on that website, your searches made on the partner’s website)

-          information related to your device (device type, operating system, version)

-          and events related to the Criteo ad serving activity such as the number of ads displayed to you.

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

  • Technical IDs of our advertising partners, and/or a hashed version of your CRM ID or of your email address – we use a double hashing method based on state-of-the art technologies to ensure the non-reversibility of your information. A hash of your email correspond to a series of characters that does not permit your identification. For eg : a hash of name@mail.com would be 98307a5ba02fa1072b8792f743bd8b5151360556b8e5a6120fa9a04ae02c88c0 
  • Mobile advertising IDs (such as Apple IDFA or Google AAID) which are specific technical data created by mobile manufacturers to allow personalization and customer analytics in a secure and non-identifying way for users

Data collected from trusted partners

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 syncing information allowing us to link users’ 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). Our partners may use probabilistic or deterministic methods but in all cases please note that beside the ID syncing information, no other data (whether personally identifying information or non-personal identifying information) that could be collected by our partners in the course of their services are shared with us. Moreover, we require that all our partners provide users with a simple way to opt out from the collection and use of their data.

We do not collect any identifying information

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 full 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 do not create segments to specifically target children under 16 years old.

We do not process any information which could be used by Criteo, directly or indirectly, to determine the personal identity of users.

We collect information in order to increase the relevancy of the ads being displayed to you. The data we collect is also used for reporting purposes, to give our clients and partners more information about the performance of their advertising campaigns, and to improve performance over time.

We may share aggregated data

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 directly identified. We share non-aggregated data only upon approval of our partners and in compliance with our commercial agreements.

We partner with Ad exchanges platforms to buy ad placements through auctions. Before the auction we link our ID with the ad exchange platform and then participate to the auction by sending the bid price and the banner code to display.

*In compliance with the best industry standards, we only use full IP addresses: 

-          For fraud detection purposes (and not for targeting purposes) to help alert us to situations which could not have been caused by human behavior, such as a massive amount of clicking in a limited period of time; or

-          To extract geographical information.
