Nevada Police Can Now Track Cellphones Without a Warrant (apnews.com)

(Sunday April 19, 2026 @05:57PM (EditorDavid) from the what-happens-in-Vegas dept.)


"Nevada quietly signed an agreement earlier this year with a company that collects location data from cellphones, allowing police to track a device virtually in real time," [1]reports the Associated Press . "All without a warrant."

> The software from Fog Data Science, adopted this January in Nevada through a Department of Public Safety contract, pulls information from smartphone apps in order to let state investigators identify the location of mobile devices. The state is allowed more than 250 queries a month using the tool, which allows officers to track a device's location over long stretches of time and enables them to see what Fog calls "patterns of life," according to [2]company documents from 2022. It can help them deduce where and when people work and live, with whom they associate and what places they visit, according to privacy experts... Traditionally, police [3]must obtain a warrant from a judge to access cellphone location information — a process that can take days or weeks. And while cellphone users may be aware that they are sharing their location through apps such as Google Maps, critics say few are aware that such information can make its way to police...

>

> Other agencies in Nevada have been known to use technology similar to Fog. In 2013, Las Vegas Metropolitan Police Department acquired [4]something known as a cell-site simulator that mimics cellphone towers and can sweep up signals from entire areas to track individuals, with some models capable of intercepting texts and calls. Police have not released detailed information about the technology since then.

"Police in other states have said the technology (and its low price tag) has helped expand investigatory capacity," the article adds.

But it also points out that Fog Data Science has a web page letting individuals [5]opt out of all their data sets .

Steps can be taken to make casual surveillance by police and other bad actors a little more difficult, such as turning off location services unless you really need them enabled. As far as I can see, though, the only way to keep the long, flexible nose of our government and corporate rulers out of our business is to poison the data pool. In this particular case, I'd just start with the consideration that there's no requirement for your phone and you to always be in the same place.

Not really. Turning off GPS and location services might "fuzz" your location to a circular error probability of a hundred yards or so. But the cops can still track you using a feed from the telecoms triangulating you within a cell site. I listen to out local cops tactical channels on a scanner and it's pretty obvious when they can locate a vehicle within a parking lot or an individual down to which business they have entered.

This. But some people are so attached to their toys they just can't leave the behind. Or so impulsive that they just knock over convenience stores on a momentary impulse. With phone still in pocket.

At bit hard to figure out your FP, but I think you are advocating for trying to muddle the data to prevent abuse. You really think you are such an expert that you can do it? Well then, congratulations, but I think you're more likely to break your phone than accomplish anything constructive or useful. There seems to a logical fallacy in thinking you can use a system that fundamentally depends on your location without revealing your location

That seems to be the thing nobody is considering here. All of this crap comes from the right wing because this is about control and that's what the right wing is always about. If you go all the way back to when the right wing got its start it's literally the side the monarchists were sitting in at the French assembly.

The fundamental concept that underpins the right wing philosophy is that there is a natural order and hierarchy that we all fit into and that we should obey the people above us and commands the people below us.

With that kind of belief system you're going to get surveillance because you aren't going to be able to maintain control otherwise.

Trying to fight tracking and privacy violations one by one is a losing battle - there will be an ever increasing number of ways to surveil people. This can only be fixed by making the collection of this type of data from ANY source illegal - and I doubt there is the political will to do that.

The data is too valuable to corporations and the government.

"Opt out of all FOG DATA SCIENCE data sets"

What -- exactly -- does that do, how quickly, and what are some of the side-effects?\

Underneath, it says "You will be removed from all our data sets." And yet I doubt that very much. Surely there will be an entry in a database somewhere saying "Device identifier ________-____-_____-_____-_____ requested removed date-and-time _____ from IP address _____", etc.

And does that only retroactively remove data? Suppose they snarf up another dataset, bought from someone else or collected by themselves. Is that data also removed from their datasets, or does another removal request have to be made?

It seems strange to me that they are using advertising IDs. Google allows users to reset and delete their Android device's Advertising ID. If an advertising ID is deleted, the device will return a string of zeros when the ID is requested. Furthermore, Google does not permit the use of Advertising IDs for purposes other than advertising and app analytics, so I reported the company to Google.

That's not exactly what the linked page says. That appears to be about searching the content of your phone. Tracking (i.e.your location) is a separate issue.

Cell site emulators/IMSI catchers/Stingrays are also popular, particularly with the feds. Our state has some pretty strict privacy laws. But they mean nothing when it's the FBI/DoJ setting the sites up. Same for surveillance camera systems. Cities around me are pretty active about giving Flock and others the boot. But the feds operate their own systems, about which local and state governments have no say. And they are pretty well hidden compared to the Flock cameras (which I think are actually going for brand recognition with their obvious installations).

Set Android advertising ID to all zeros (Score:5, Interesting)

by schwit1 ( 797399 )

This should foil fogs data?

On stock systems, the UUID you are seeing is almost certainly the **Advertising ID** (Android) or **IDFA** (iPhone). Here is how to manage them:

1. **To Reset the ID:** Go to **Settings > Privacy > Ads** (or **Settings > Google > Ads**). Tap **Reset advertising ID**. This generates a completely new random UUID.

2. **To Delete the ID:** In the same menu, tap **Delete advertising ID**.

* *Result:* Instead of a random string, apps will see a string of zeros (`00000000-0000-0000-0000-000000000000`). This is effectively "randomizing" it by making it useless for tracking.

3. **Automatic Randomization:** Stock Android does **not** have a native setting to rotate this ID automatically (e.g., daily). Only privacy-focused ROMs like CalyxOS or GrapheneOS offer that "shuffle" behavior.

1. Apple Advertising > Personalized Ads (turn off)

2. Tracking > Allows Apps to Request to Track (turn off)

3. If any apps are already listed under Tracking, revoke their permission to track
