Do Not Sell My Personal Information

As the Un-carrier, we are 100% committed to our customers, which is why we want to take the time to explain exactly what the “Do Not Sell My Personal Information” link on T‑Mobile websites and apps means. An example of a “sale” under the California Consumer Privacy Act (CCPA) is when we share information about you (like when you’ve visited our sites or the apps you have on your phone) tied to unique identifiers, like device IDs, with third parties for targeting advertising. When you tell us not to sell your personal information, we won’t share your information for these purposes. Of course, not all sharing of personal data is a sale, like when T‑Mobile shares your data with service providers to provide our products and services.

The purpose of this article is to explain (1) why T‑Mobile's websites and apps contain the “Do Not Sell” link, (2) what it means, in greater detail, to “sell” “personal information,” as those terms are defined under California law (3) whether T‑Mobile “sells” your personal information, (4) what happens if you tell T‑Mobile not to “sell” your personal information, (5) how T‑Mobile implements your choice to block it from “selling” your personal information, and (6) how T‑Mobile maintains your “Do Not Sell” choice.

1. Why Does T‑Mobile Provide the “Do Not Sell” Link?

T‑Mobile provides the “Do Not Sell” link to comply with the California Consumer Privacy Act (CCPA), California Civil Code Section 1798.100 et seq., effective January 1, 2020. The CCPA is a data protection law that provides California residents with certain choices about their data, including the ability to tell companies not to “sell” their personal information. Although the CCPA only gives California residents the right to make these requests, T‑Mobile provides non-California residents with the same choices about their personal information. See our Privacy Notice for more information.

2. What Does it Mean to “Sell” “Personal Information” Under the CCPA?

The CCPA defines “sale” and “personal information” beyond how you might commonly interpret those terms.

Under the CCPA, “personal information” includes information that is not necessarily directly tied to an individual’s identity but may be associated with a device. This includes identifiers such as IP addresses, web cookies, web beacons, and mobile Ad IDs. In many cases, these types of information do not directly identify you, but they are unique identifiers that could be linked to you and therefore covered by the CCPA. The term “sell” is broadly defined to include not just selling in exchange for money, but also sharing personal information (including information that does not directly identify an individual as described above) in exchange for anything of value, which is not limited to the exchange of money.

Certain things are not considered “sales,” including when (1) personal information is shared with a service provider that is contractually prohibited from using the personal information for any purpose beyond the service specifically requested (the CCPA’s “service provider exception”), or (2) when the consumer has directed a company to disclose the personal information (the CCPA’s “consumer directed exception”).

3. Does T‑Mobile “Sell” my Personal Information?

Under the CCPA’s broad definition of “sell,” which includes even the common flow of information in the digital analytics and advertising ecosystem, T‑Mobile does “sell” personal information. Like most companies that operate websites and apps, T‑Mobile uses online analytics to measure the ways users engage with our websites and apps. These analytics, in turn, inform how we perform online advertising. In order to provide these analytics and facilitate online advertising, T‑Mobile uses third-parties that collect device identifiers and place tags, cookies, beacons, and similar tracking mechanisms on our digital properties and on third-party digital properties. For example, T‑Mobile may request that a third-party facilitate the placement of T‑Mobile ads on a particular website after a consumer has previously visited T‑ The third-parties T‑Mobile uses for these purposes generally do this by placing a cookie on a user’s browser so it can identify that the same browser visited other websites. Similarly, where digital properties provide space for advertisements, these third-parties may use identifiers such as cookies for websites, or the device’s mobile Ad ID for apps, to facilitate real-time bidding by advertisers.

Under its personalized ad program, T‑Mobile uses and analyzes data from sources such as device and network diagnostic information (Android users only), apps on your device, and broadband information. This data helps T‑Mobile understand more about user interests (e.g., sports enthusiast, loves cooking, etc.). Using this information, T‑Mobile creates groups known as “audience segments,” which may be used by T‑Mobile or sold to third parties to make ads more relevant to you. When T‑Mobile sells audience segments, it does not sell information that directly identifies customers, like name, address, or email. Rather, audience segments are associated with mobile Ad IDs, which are long set of numbers and letters. For example, this might say something like "2drdn43np2cMapen084 is a sports enthusiast." Take a look at the Advertising and Analytics article and T‑Mobile’s Privacy Notice for details. T‑Mobile’s “Do Not Sell” choice applies to our personalized ad program.

Where T‑Mobile can reasonably ensure via contract that the third-parties described above can and will use a device identifier solely to provide the specific service T‑Mobile has requested, and will not use or share the data for other purposes, T‑Mobile will not deem that sharing a “sale” under the CCPA’s service provider exception.

4. What Happens when I Tell T‑Mobile not to “Sell” my Personal Information?

When a user of T‑Mobile websites or apps makes the “Do Not Sell” choice, T‑Mobile will block further sharing of the covered identifiers with the third-parties we engage on those digital properties with.

Whether you opt out of the sale of your personal information or opt out using T‑Mobile's advertising settings here, your info is not used in T‑Mobile's ad program. Note that Assurance Wireless is not included in T‑Mobile's ad program.

5. How Does T‑Mobile Implement my Choice to Block the “Sale” of my Personal Information?

The implementation of your choice to block the sale of your personal information is complex and will vary between T‑Mobile brands, websites, apps, and other digital properties. As general rule, when you click the “Do Not Sell” link, you will be provided two choices: (1) set a “Do Not Sell” preference using a cookie for the particular web domain (such as T‑ or that is not tied to your account, or (2) if you have or create accounts with T‑Mobile, you can sign in to your relevant T‑Mobile accounts and apps (such as T‑Mobile Tuesdays) and set a persistent “Do Not Sell” preference that T‑Mobile can store as part of our customer records for those respective accounts.

6. How Does T‑Mobile Maintain my “Do Not Sell” Choice?

For T‑Mobile websites, if you do not log in to your account (or do not have an account with T‑Mobile) and instead set a “Do Not Sell” preference that is specific to the site that you are visiting, please be aware that your choice will only work if your browser is set to accept cookies. Likewise, if you clear your browser cookies, the cookie-based “Do Not Sell” setting will be erased, and you will need to reset your choice for that web domain. For T‑Mobile apps, the local setting should remain until you specifically change it or clear app data on your device— but you should check the setting regularly to ensure it reflects your current choice.

If you sign in and set a “Do Not Sell” setting tied to your account, T‑Mobile will honor that setting for the related service whenever you are logged into that account. Please note that your setting for an account associated with one T‑Mobile brand may not apply across all T‑Mobile brands, and you will have to log into each brand account separately to set your preferences. For example, if you change your preferences with your main T‑Mobile account, those settings will not automatically apply to Metro by T‑Mobile.

Your persistent choice will have no effect, however, when you are not signed-in to a T‑Mobile account. In this case, only your choice set for a particular website or app, if one exists, will apply. Please note that when you set a “Do Not Sell” choice in your account, T‑Mobile will attempt to also set your setting for the website or app you are using at that time – but again, that setting may not work depending on your settings and actions (for example, if your browser does not accept cookies or if you later delete cookies or reset device IDs or delete data on your app).

You can check the current status of your “Do Not Sell” choice for a specific T‑Mobile website or app and change that setting at any time by clicking on the link in the footer of the T‑Mobile webpage you are browsing or in the menu section of the T‑Mobile app you are using.
