T-Mobile will sell your web-usage data to advertisers unless you opt out
T-Mobile next month will start a new program that gives customers’ web-browsing and device-usage data to advertisers unless customers opt out of the data sharing.
“[S]tarting April 26, 2021, T‑Mobile will begin a new program that uses some data we have about you, including information we learn from your web and device usage data (like the apps installed on your device) and interactions with our products and services for our own and 3rd party advertising, unless you tell us not to,” T-Mobile said in a privacy notice. “When we share this information with third parties, it is not tied to your name or information that directly identifies you.”
For directions on how to opt out of the expanded data sharing, see the first section of the T-Mobile privacy notice. There’s also an opt-out link here.
