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.
2 – Our technology
Online web environment: (desktop, tablet, and smartphone browsers)
Criteo “tags” visitors to its partners’ websites with anonymous browser cookies. Users tagged by Criteo are given an anonymous identifier. At no point does Criteo collect 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 anonymous data from 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:
- Session cookies are used to make it easier for you to navigate on websites. A session ID cookie expires when you close your browser.
- Persistent cookies are used to run our technology as they enable us to track and target the interests of our users to enhance the experience on our partners’ websites. Persistent cookies remain on your hard drive for an extended period of time. You can remove persistent cookies by following the directions provided in your internet browser’s ‘help’ file.
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.
Other environments (Mobile applications)
In environments that do not support cookies, like mobile applications, we may use other anonymous technologies for the same purpose of cookies. To serve our ads in mobile applications we collect identifiers, such as Android Id or IDFA depending on the operating system of your mobile device. These identifiers consist in a string of anonymous and random characters singling out your device that Criteo stored by Criteo with a hash (non reversible encrypting method).
3 - Data collection and use
|We collect anonymous information||We do not collect any personal information|
We collect only anonymous data through anonymous cookies or equivalent identifiers that record:
We do know that the internet browser and/or mobile operating system you are using has visited one of our partner sites in the last thirty days.
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 or any other personally identifiable information about you. 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.
*In compliance with the best industry standards, we use 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.

You may also want to use browser settings to modify your preferences. At Criteo our goal is to offer a harmonized online experience whatever browser you use. Most browsers accept our cookies by default but in certain cases, like Safari, our cookies are blocked by default by the browser settings (and potentially without your knowledge). In these situations we will inform you before we drop our cookies so that you can tell us either that you want to experience our ads, or opt-out of our services by using the Criteo opt-out. In cases where you interact with our service and want to experience our personalized ads your browser settings may nonetheless be configured to block certain third party cookies. In this situation, the most efficient way to disable our ads in for these browsers is by using our Opt-out.
As described above, we elected to provide mechanisms of choice through our proprietary opt out and through industry platforms and do not respond to web browser do not track signals.
Other environments (Mobile applications)
Please note: to opt-out from advertising served by Criteo in mobile applications, you must be browsing in applications.
iOS 6 users (version 6 and above)
To use the “Limit Ad-Tracking” option, follow the instructions provided by Apple here: Apple Support Center
Please note that this is a device setting and will disable interest-based ads from all providers, and not just for Criteo
Criteo services only work with iOS (version 6 and above), so we do not provide interest-based ads on other platforms
