Some of this information (including for example IP addresses and certain unique device identifiers), may identify a particular computer or device, and may be considered "personal data" in some jurisdictions, including the European Union.

Information Collected Automatically. As is true of most websites, we gather certain Digital Identifier Information automatically. This information may include Internet protocol (IP) addresses, browser type, Internet service provider (ISP), referring/exit pages, the files viewed on our site (e.g., HTML pages, graphics, etc.), operating system, date/time stamp, and/or clickstream data to analyze trends in site usage and administer the site (e.g. managing user sessions and detecting and preventing malicious behavior on the site).

Tracking Collection and Technologies. We and our partners use cookies and similar technologies to analyze trends in site usage, administer the website, and track your movements around the website. We use cookies which are small text files stored on an Internet user's computer. The cookies store information related to your navigation on our website.

Our cookies and web beacons are set and read for the following purposes:

  • Personalization of your navigation. These cookies enable us to recognize you and remember any information you enter during your navigation on our website (such as language choice, country you are browsing from, or browser type). This makes your visit on our website easier as we don't ask you the same information several times during your navigation.
  • Advertising our business on other Sites. Sometimes, we use Digital Identifier Information to advertise our business on other sites, including through the AppNexus Platform. When we advertise to our clients and prospective employees using the AppNexus Platform, we act as a customer of the AppNexus Platform, using our own information, and we do not use or mix our information with the proprietary information of other AppNexus Platform customers. You can learn more about the AppNexus Platform in the AppNexus Platform Privacy page, where you can also learn about how to opt out of having the Platform used by us and others for interest-based advertising.

We process this data as necessary to further the legitimate interests of our company while ensuring appropriate privacy protections.
  • As a resident of a country in the EEA, with respect to your personal data you have the right to: (i) request access and obtain a copy of your personal data, (ii) request rectification or erasure; (iii) to restrict the processing of your personal data; and (iv) if applicable, to data portability.

  • We will seek to provide access to such data, but will not be able to do so when the burden or expense of providing access would be disproportionate to the risks to the individual's privacy in the case in question, or where the rights of persons other than the individual would be violated.

Advertising on the AppNexus Platform

Global Operations and Privacy Shield

  • AppNexus is a global company headquartered in the United States with data centers located in the United States, Europe and Asia. If you access please be aware that your information may be transferred to, stored and processed by us and our affiliates in our facilities in the United States and other countries (including in Singapore, Japan, Australia and Brazil where our global affiliates have offices) and by those third parties with whom we may share your information.
  • These countries (including the United States) may not provide an adequate level of data protection for your information (as determined by the European Commission) or have data protection or other laws as comprehensive as those in your country. We will, however, ensure that where AppNexus group companies or third party service providers receive information about you outside of the EEA, appropriate protections are in place under European data protection legislation (which includes either Model Clauses or Privacy Shield compliance).
  • For example, in order to ensure that your information is adequately protected when transferred outside of the EEA, AppNexus has entered into inter-company "model clause" agreements and other adequacy arrangements with other various entities located outside the EEA with whom we share your information. A copy of such agreements is available on request.
  • Additionally, if we transfer personal information from the European Union to the United States or Switzerland to the United States, we comply with the EU-US Privacy Shield Framework and the Swiss-US Privacy Shield Framework as set forth by the US Department of Commerce regarding the collection, use, and retention of personal information transferred from the European Union and Switzerland to the United States, respectively. AppNexus has certified to the Department of Commerce that it adheres to the Privacy Shield Principles. To learn more about the Privacy Shield program, and to view our certification, please visit
  • For any questions or complaints regarding our compliance with either the EU-US Privacy Shield Framework and the Swiss-US Privacy Shield Framework, please contact us here. If AppNexus does not resolve your complaint, you may submit your complaint free of charge to ICDR/AAA, AppNexus' designated independent dispute resolution provider. Under certain conditions specified by the principles of the EU-US and the Swiss-US Privacy Shield Frameworks, respectively, you may also be able to invoke binding arbitration to resolve your complaint. AppNexus is subject to the investigatory and enforcement powers of the FTC. If AppNexus shares the personal data of an individual located in the EU or Switzerland with a third-party service provider that processes the data solely on AppNexus' behalf, then AppNexus will be liable for that third party's processing of that data in violation of the Principles, unless AppNexus can prove that it is not responsible for the event giving rise to the damage.

What Happens if this Privacy Statement is Changed? Check this page for changes. We may change this privacy statement at any time. If we make changes that, in our sole discretion, are material, those changes will not be applied to information collected prior to the date the changes went into effect.
