T-Mobile Has Started Selling Your App Data To Advertisers

T-Mobile has just officially launched its new ad platform, known as T-Mobile Advertising Solutions. That innocuous name hides a rather sketchy business model -- it aggregates your mobile application usage and sells it to advertisers. Android Police reports: The specifics of the program will sound familiar to anyone who has followed the ebb and flow of browser tracking. T-Mobile uses network-level tools to track the apps that people use on their phones, and it then anonymizes and aggregates that data to lump you into various "personas," or "cohorts" as other platforms would call it. For example, if you regularly use Expensify and airline apps on your phone, T-Mobile could identify you as a business traveler for advertising purposes. This program has been in testing for the past year as "T-Mobile Marketing Solutions," according to The Verge, but it is now live with its new name. There is some good news (but less of it for Android fans). T-Mobile does not currently collect app data on iOS users, fearing it could run afoul of Apple's privacy rules. But we Android users are fair game, apparently. However, you can opt-out of T-Mobile's program using its official "Magenta Marketing Platform Choices" app. Alternatively, the Digital Advertising Alliance offers an app that lets you opt-out of numerous trackers, including T-Mobile Advertising Solutions, which is listed under its old name of T-Mobile Marketing Solutions.
