T-Mobile Privacy Notice

This is T-Mobile's privacy policy explaining what personal information they collect about you and how they use and share it. The most important thing to know is that T-Mobile collects and may share your precise location data, call records, browsing activity on their network, and financial information with advertising partners and third-party data brokers — and you must actively opt out to limit this. California residents and users in other states with privacy laws can submit a data deletion or opt-out request at T-Mobile's Privacy Center at t-mobile.com/privacy-center.

This document is T-Mobile's Privacy Notice governing the collection, use, sharing, and retention of personal data for customers, prospective customers, and visitors to T-Mobile's websites, apps, and services, with legal basis rooted in contractual necessity, legitimate interests, and consent under applicable US state and federal telecommunications privacy law. The notice requires T-Mobile to disclose its collection of an exceptionally broad category of personal data including precise geolocation, CPNI (Customer Proprietary Network Information), biometric identifiers, financial data, device identifiers, network usage patterns, and inferred characteristics derived from data analytics. Notably, T-Mobile explicitly reserves the right to share personal data with a wide array of third parties including advertising partners and data aggregators, and uses location and network usage data for targeted advertising — a practice that deviates from consumer expectations for a primary telecommunications provider and carries heightened risk given T-Mobile's prior FCC and FTC enforcement history regarding data breaches and unauthorized data sharing. The notice engages CPNI regulations under 47 U.S.C. § 222, CCPA/CPRA (Cal. Civ. Code §1798.100 et seq.), COPPA (15 U.S.C. § 6501), state biometric privacy statutes including Illinois BIPA (740 ILCS 14), and FTC Act Section 5, with enforcement by the FCC, FTC, and state attorneys general; material compliance considerations include the adequacy of opt-out mechanisms for data sale and sharing, the sufficiency of CPNI consent disclosures, and the lawfulness of using sensitive network-derived data for commercial advertising purposes.
