Inside the U.S. Government-Bought Tool That Can Track Phones at Abortion Clinics

The tool, called Locate X and made by a company called Babel Street, then narrows down to the movements of a specific device which had visited the clinic. This phone started at a residence in Alabama in mid-June. It then went by a Lowe’s Home Improvement store, traveled along a highway, went past a gas station, visited a church, crossed over into Florida, and then stopped at the abortion clinic for approximately two hours. They had only been to the clinic once, according to the data. ALT
In other words, someone had traveled from Alabama, where abortion is illegal after the June 2022 overturning of Roe v. Wade, to an abortion clinic in Florida, where abortion is limited but still available early in a pregnancy. Based on the data alone, it is unclear who exactly this person is or what they were doing, whether they were receiving an abortion themselves, assisting someone seeking one, or going to the clinic for another reason. But it would be trivial for U.S. authorities, some of which already have access to this tool, to go one step further and unmask this or other abortion clinic visitors. ALT
This sort of surveillance is only possible because of the mobile advertising ecosystem. Location data is sometimes used to build profiles on device users and better target advertisements to them. Much of that advertising relies on a MAID, the unique advertising ID, on a phone. The MAID acts as the digital glue between a device and its associated data.ALT

anyway yeah DELETE YOUR FUCKING ADVERTISING IDS

Android:

Settings ➡️ Google ➡️ all services ➡️ Ads ➡️ Delete advertising ID

(may differ slightly depending on android version and manufacturer firmware. you can’t just search settings for “advertising ID” of course 🔪)

iOS:

Settings ➡️ privacy ➡️ tracking ➡️ toggle “allow apps to request to track” to OFF

and ALSO settings ➡️ privacy ➡️ Apple advertising ➡️ toggle “personalized ads” to OFF

Okay, but also, don’t bring your phone with you if you’re doing something that could get you in legal trouble. You can get a burner phone (such a tracfone) and prepay for minutes using cash if you need to. But if you don’t want to be tracked, the most foolproof plan is to not bring a device that can track you. (Don’t bring your laptop, either.)
