How we make ads more relevant
We use information about the apps on your device and how frequently you use them, as well as other general data you provide, to create personas. Each persona is associated with a Mobile Advertising ID (MAID), which is a random sequence of letters and numbers assigned to your mobile device. It doesn’t include your name, phone number, or any other information that directly identifies you. For example, your persona might appear as “38400000-8cf0-11bd-b23e-10b96e40000d: pet owner, sports fan.”
MAIDs can be associated with multiple different personas. You might fit into a persona for cooking or travel, or both. For example, if you have the “Booking” and “Concur” apps, we might infer that you’re a business traveler and associate your MAID with that persona. Or if you have the “ESPN” app and another sports app, we might infer that you’re a sports lover and associate your MAID with that persona.
Personas are used in our

Under
- Your device
- Your network diagnostic information (Android users only)
- Your broadband usage (top-level name/URL of the website you visited only—not the web pages within the site you visited)
Note: We don’t collect data for personalized ads and offers from iPhone users.
If you don’t want us to use your personal data to send you personalized ads or offers, you can change your settings in our Privacy Dashboard at any time.
What data we use
The data we use to create personas for relevant ads
App engagement data
We use app usage information from the apps on your phone (Android only) and high-level app usage data from your
To illustrate what we mean by "high-level app usage data from your broadband,” we process the name of an app you opened, such as a recipe app, and how long you spent in that app—but we don’t see any additional information, like, for example, that you looked at Italian or Thai recipes.
Demographics data
When you use our products and services, you may provide some information about yourself directly to us. This “self-declared data”—including your age range, such as 25-34, and gender—is used to create personas but isn’t used to provide you with relevant ads.
The data we use to provide you with relevant ads
Mobile Advertising ID (MAID)
We and our advertising partners use your MAID to deliver relevant ads to you.
Third-party data
We and our advertising partners use data from third parties, such as your MAID, to deliver relevant ads to you.
The data we use to further personalize ads and provide you offers
In addition to the MAID and third-party data described above, if you’ve opted in, we use the following types of data to personalize ads and provide you offers:
Location data

Demographics data
When you use our products and services, you provide some information about yourself directly to us. This “self-declared data”—including your age range, such as 35-54, gender, interests, and survey responses—is also used to provide you with more personalized ads and offers.
Broadband data
Your top-level domain/URL information about your web browsing activity—what websites you visit—will be used to provide you with more personalized ads and offers.
To illustrate, we process the top-level name/URL of the website you visit, such as a major retail website, but we don’t look at which web pages (clothes or toasters, for example) you visit within that site.
How to opt out
How to opt out of relevant ads and personalized ads and offers
- Go to our Privacy Dashboard.
- Review the descriptions under “Relevant ads” and “Personalized ads and offers.”
- If you want us to stop using your personal data to match you with relevant ads, set the “Relevant ads” toggle to “OFF” or gray.
