T-Mobile uses your network activity, app usage, location, and demographic information to build advertising profiles and serve you targeted ads, and may share this data with advertising partners.
Your browsing and location data collected through T-Mobile's own network is being monetized for advertising purposes, which represents a significant use of sensitive behavioral data beyond basic service delivery.
This program implicates CPRA 'sharing' definitions for cross-context behavioral advertising, requiring a clear opt-out mechanism and disclosure in the privacy notice; non-compliance carries enforcement risk from the California Privacy Protection Agency.

T-Mobile collects extensive personal data including precise geolocation, network browsing activity, CPNI, biometric data, and financial information, and uses it for targeted advertising as well as sharing with affiliates, partners, and third-party data brokers. Consumers' data may be sold or shared in ways that affect their privacy and financial profile, and some data sharing persists even after account cancellation due to legal retention obligations.
