You probably think your phone's location is private unless a judge says otherwise. You're wrong. In Nevada, the state government recently bypassed the standard warrant process by signing a quiet deal with a private data broker. This allows investigators to track "patterns of life" for hundreds of devices every month without ever stepping foot in a courtroom.
It’s a loophole that makes the Fourth Amendment look like a suggestion rather than a rule. You might also find this similar story insightful: Pentagon Lasers on the Border Raise the Stakes for Civilian Airspace.
The Invisible Contract Tracking Your Every Move
The Nevada Department of Public Safety recently inked a deal with a company called Fog Data Science. This isn't your typical police surveillance. Usually, if the cops want to know where you've been, they have to go to a provider like AT&T or Google with a warrant. That takes time. It requires probable cause.
The Fog Data Science tool skips all of that. As reported in latest articles by MIT Technology Review, the effects are widespread.
By paying roughly $12,000 a year—a price point so low it only required a clerk’s signature instead of a public vote by the governor or attorney general—Nevada investigators gained access to a massive database of location pings. We aren't just talking about one or two suspects. The contract allows for over 250 queries per month.
How They Get Your Data Without Asking
If you use a weather app, a coffee shop loyalty program, or a navigation tool, you’ve likely "consented" to sharing your location with "third-party partners." You think you’re just getting a local forecast. In reality, that app is selling your coordinates to data brokers.
Fog Data Science buys this data in bulk. They don't need to ask the phone companies for anything because the data is already out there on the open market.
- Advertising IDs: Your phone has a unique string of numbers used to serve you ads. Fog tracks this ID.
- Historical Breadcrumbs: They can look back months or even years to see where a specific device spent its nights.
- Pattern Analysis: Investigators can see which devices frequent the same locations, effectively mapping out your social circle and workplace habits.
The Nevada Threat Analysis Center and the Investigation Division are the primary users here. They claim they only use it for specific investigations, but privacy advocates from the Electronic Frontier Foundation (EFF) point out that 250 queries a month is enough to cast a very wide net.
The Legal Gray Area That Should Worry You
You might remember the 2018 Supreme Court case Carpenter v. United States. The court ruled that the government generally needs a warrant to access cell site location information. It was a huge win for privacy.
But there’s a catch.
Law enforcement agencies argue that since this data is "commercially available" and "voluntarily" shared with apps, the warrant requirement doesn't apply. They're essentially buying their way around the Constitution. If they can buy the information from a private company, they don't think they're "searching" you in the legal sense.
John Piro from the Clark County Public Defender’s Office has been vocal about this. He argues that using an app like Waze shouldn't mean you've signed away your right to move through the world without the government watching over your shoulder. Yet, until a court specifically bans the purchase of broker data, the practice continues in the shadows.
It Is Not Just About Criminals
The danger of "mass surveillance on a budget" is that it makes everyone a suspect. If a protest happens in Las Vegas, or a crime occurs near a specific park, police can use "geofencing" techniques to see every device that was in the area.
They can then trace those devices back to their "resting spots"—aka your home.
Even if you’ve done nothing wrong, your presence in a certain geographic box at the wrong time could land you in a police database. The data is supposed to be "anonymous," but anyone with a map can see that a phone that sleeps at your house and works at your office isn't anonymous at all. It's you.
How to Tighten Your Privacy Settings Right Now
You can't completely vanish from the grid if you carry a smartphone, but you can make it much harder for brokers to profit off your movement.
- Reset your Advertising ID: On Android, go to Settings > Google > Ads > Reset Advertising ID. On iPhone, go to Settings > Privacy & Security > Tracking and turn off "Allow Apps to Request to Track."
- Audit your App Permissions: Go through every single app on your phone. If a calculator or a game is asking for "Always Allow" location access, deny it. Set everything to "Only While Using" or "Never."
- Opt-Out via Fog: Fog Data Science actually has an opt-out tool on their website. It requires your device’s advertising ID, but it’s one of the few ways to explicitly tell them to stop indexing your data.
- Use a Privacy-Focused Browser: Standard mobile browsers leak data like a sieve. Switch to something like DuckDuckGo or Brave to minimize the digital trail you leave while surfing the web on the go.
Don't wait for the Nevada legislature to fix this. They've shown that as long as the price tag is low enough, they're happy to let the tracking continue without public oversight. Take control of your device's permissions today or accept that your "patterns of life" are essentially public property.
