404 Media, along with Haaretz, Notus, and Krebs On Security recently reported on a company that captures smartphone location data from a variety of sources and collates that data into an easy-to-use tool to track devices’ (and, by proxy, individuals’) locations. The dangers that this tool presents are especially grave for those traveling to or from out-of-state reproductive health clinics, places of worship, and the border.

The tool, called Locate X, is run by a company called Babel Street. Locate X is designed for law enforcement, but an investigator working with Atlas Privacy, a data removal service, was able to gain access to Locate X by simply asserting that they planned to work with law enforcement in the future.

With an incoming administration adversarial to those most at risk from location tracking using tools like Locate X, the time is ripe to bolster our digital defenses. Now more than ever, attorneys general in states hostile to reproductive choice will be emboldened to use every tool at their disposal to incriminate those exerting their bodily autonomy. Locate X is a powerful tool they can use to do this. So here are some timely tips to help protect your location privacy.

First, a short disclaimer: these tips provide some level of protection to mobile device-based tracking. This is not an exhaustive list of techniques, devices, or technologies that can help restore one’s location privacy. Your security plan should reflect how specifically targeted you are for surveillance. Additional steps, such as researching and mitigating the on-board devices included with your car, or sweeping for physical GPS trackers, may be prudent steps which are outside the scope of this post. Likewise, more advanced techniques such as flashing your device with a custom-built privacy- or security-focused operating system may provide additional protections which are not covered here. The intent is to give some basic tips for protecting yourself from mobile device location tracking services.
