AT&T Inc.

As a major telecommunications provider, AT&T collects a vast amount of personal data from its millions of customers, including account details, device information, location data, and web browsing and app usage history. The company utilizes this extensive dataset, supplemented with information from third-party sources like marketing lists and credit reports, to create detailed customer profiles for targeted advertising and marketing purposes. AT&T's privacy policy notes that it shares customer information in ways that may be considered a "sale" under some state laws, such as providing identifiers to other advertising companies. This practice, combined with a history of data breaches and past instances of selling customer location data to third-party brokers, exposes individuals to significant risks including fraud, identity theft, and stalking. To mitigate these risks, individuals should carefully manage their privacy settings, limit the personal information shared, and exercise their rights to opt out of certain data collection and marketing programs offered by the company.
