Company Privacy Policy

Millennial Media is committed to protecting consumer privacy and to clearly informing users about the collection and use of information when using our services. As a result, we have put together this Privacy Policy to explain how we collect and use certain information. This Privacy Policy and the opt-out choices below apply to Millennial Media's mobile advertising products and services, including those of our Jumptap subsidiary (collectively, our “Service”). This Privacy Policy also applies to our company websites located at, (“mMedia”), and (collectively, our “Websites”). Our Nexage subsidiary currently operates independently and maintains its own privacy policy that describes its data collection and use practices, which you can review at


Our Business

Millennial Media is a mobile advertising company. We use our proprietary technology to offer advertising solutions to our clients, which includes working with advertisers to deliver their advertising campaigns across our network of mobile publishers and application (“app”) developers (our “Platform”).


Information Collection and Sharing

Website Data Collection. Millennial Media is the sole owner of the information collected on our Websites. The information may consist of both Personally Identifiable Information (“PII”) and Non-Personally Identifiable Information (“Non-PII”), and is collected in order to conduct business with current and prospective business clients. We do not sell or rent data collected via our Websites to other parties, but we may provide it to third parties as necessary to conduct our business operations and to our customers for the performance of our Services, or we may disclose such data as otherwise described in this policy. Millennial Media uses these data to provide requested information to prospective clients, to establish self-service advertiser and publisher accounts, and otherwise as necessary to conduct our business.  If you would like to review or request changes to PII that you have submitted through our Websites, or would like to request that we not share your PII with third parties, please contact us using the information below.


Data Collected On Our Platform and from Partners. Millennial Media collects data from across our Platform. This data, which may include anonymous identifiers associated with your mobile device and the location of your device, does not identify you personally, and may come from such sources like your mobile web browser, or the apps that you use. We use a variety of technologies to collect this data, including “cookies,” which are small text files that can be stored on your browser. We may also collect and/or use information collected by our partners and shared with us, and data from third party business partners.  We use this Non-PII along with our technology to perform a variety of tasks, such as improving the relevance of the ads, limiting the number of times a specific advertisement is presented to the same mobile device (frequency capping), providing an advertisement to only certain types of mobile devices, or providing a report to a client on the number of its advertisements that were clicked. We may share this Non-PII with clients, vendors, and other companies with whom we conduct business, and as otherwise described in this policy. We may also use some of this data to provide interest-based advertising, as discussed more fully below.


Other Information Sharing. Millennial Media’s affiliated entities covered by this policy may share data with each other or with other affiliated entities.  We may also share any aggregate or de-identified information with our partners.  We may disclose information, including PII, when in our sole judgment we are required to do so by law, regulation, or when such action is necessary to comply with a current judicial proceeding, a court order or legal process.  Additionally, there may be times where we will need to disclose information to protect our system or our rights or to ensure your safety or the safety of others. We may also transfer all or some of the data discussed in this policy, in connection with a corporate merger, acquisition, partial or total sale of assets, bankruptcy, or any other corporate change.


Interest-Based Advertising and Opt Out

Millennial Media works with its clients to provide ads that are likely to be more interesting and more relevant to mobile device users. One way we do this is by using our technology, along with Non-PII related to your mobile device that is gathered across different sources. Examples of this data, which does not identify you personally (Non-PII), may include things like mobile websites you have visited or mobile apps that you use, preferences that you may have provided to your app provider or to Millennial Media (as in a survey), information collected by our partners and other third parties and shared with us, or location information. We may link an identifier to additional data from other partners to provide us with some information about users’ likely interests (for example, that a user seems to be interested in purchasing a new car). When we have such information, the ads that we display to that user can be more relevant to his or her interests.


If you would like to opt out of the use of data for interest-based advertising by Millennial Media, as well as Millennial’s Jumptap subsidiary, please visit both opt-out links below and follow the instructions provided.

Ads. We may also provide ads that link to third-party sites, third-party apps, or other third-party content (“Third-Party Content”). This Privacy Policy does not extend to Third-Party Content, or any services offered on Third-Party Content.


Data Collection On Behalf Of Third Parties

We may, on behalf of our clients and partners, collect information from end users. This may occur, for example, if someone submits information in response to an ad that we provide on behalf of an advertising client. Such information may consist of PII, non-PII, or both. In such situations, we collect the information and provide it to our client, and it will be subject to that client’s privacy practices.
