We use partners to provide us with the following categories of data:

Identifiers Matches

Examples:

The Criteo UID=13278a5c-3997-4b97-826d-19609eecb975 and the advertising ID 6D93078A-8259-4BA4-AE5B-76104861E7DC belong to the same person,
but this person cannot be identified.

The Criteo identifier UID=13278a5c-3997-4b97-826d-19609eecb975 corresponds to the partner identifier PartnerID=xxxxxxx.

The Criteo UID=13278a5c-3997-4b97-826d-19609eecb975 and the hashed email address 98307a5ba02fa1072b8792f743bd8b5151360556b8e5a6120fa9a04ae02c88c0 belong to the same person, although this person cannot be identified.

Our partners provide us with matches between several identifiers to allow us to more effectively associate multiple identifiers. The combination of Criteo identifiers allows us to offer you a harmonized experience of our services regardless of the environment from which you are browsing. Learn more about how Criteo services works across multiple environments.

Data allowing us to fight against fraud

Example:

List of truncated IP addresses identified as carrying out fraudulent activities.

In order to combat fraud, we use partners to detect and report fraudulent activities (for example, resulting from a computer bot rather than human interaction.)

Geolocation data

Examples:

• The IP address used to visit the website is in the United States.
• The IP address used to visit the website is New York City.
• The product ABC has been purchased by the Criteo UID=13278a5c-3997-4b97-826d-19609eecb975 in the brick and mortar store 123 of the Advertiser XYZ

Our partners provide us with information about your geographical location derived from your IP address, points of interest that are near you (e.g. stores that are geographically close to you) or the products you have been purchasing in a brick and mortar store of the advertisers that are using our services to manage their online marketing campaigns. This allows us to improve the relevance of our services by displaying advertisements forproducts available in your geographical area.

In order to have advertising inventories on which to display our ads, we participate in real-time auctions (often called “Real-Time Bidding”) on marketplaces. To do this, we must synchronize the identifiers used by Criteo with those used by these marketplaces in order to participate in the auction by sending our bid and the advertising we wish to display.

This means that we must communicate to these marketplaces the identifier that we use to recognize your browser or device without ever being able to identify you.

Some Advertisers use data platforms (namely platforms named “Data Management Platforms” or “Customer Data Platforms“), which allow them to facilitate the implementation of audience segmentation and communicate it to online advertising industry players such as Criteo. These communications require the synchronization of the identifiers used by Criteo with those used by this platform when you visit an Advertiser site.

This implies that we communicate to these platforms the identifier that we use to recognize your browser or device without ever being able to identify you.

In order to more effectively associate Criteo identifiers with each other, we may need to share with partners the identifier of a Criteo cookie that we have assigned to your web browser. The combination of Criteo identifiers allows us to offer you a consistent experience of our services regardless of the environment from which you are browsing.

We provide limited data to our anti-fraud partners to enable them to effectively detect and report fraudulent activity to us.

We may transmit your IP address to our partners so that they can deduce from it information that is not specific to your geographical location (country, region or city). This allows us to improve the relevance of our services by displaying advertisements for products that are available in points of sale near you.

Some of our clients may ask us to exchange some data with their partners, through the ads we serve to you for purposes compatible with the purpose of displaying personalized advertisements, for instance to mesure the efficiency of their campaigns.

We may transmit data to our subsidiaries and affiliates for processing in accordance with this notice for the purposes of our services.

In addition, Criteo reserves the right to disclose all or part of its data in the event of a merger, acquisition, dissolution or sale of all or part of its assets. You will then be informed by email and/or by a prominent message on our website of any change in ownership or regarding the use of your data and the rights you will have over them.

In some situations, we may disclose data in response to legal requests from authorities, such as to comply with the law or national security requirements. We may also disclose information about you if required by law, such as to comply with a subpoena or other legal process or if we believe in good faith that such disclosure is necessary to protect our rights, your safety or the safety of others, investigate a case of fraud or respond to a request from the government.
