Your phone has been tracking your location all day.
Right now, it knows where you slept last night, where you work, which route you took this morning, how long you spent at the pharmacy, and whether last Tuesday evening was at home.
Most of that location data is quietly shared with companies you have never heard of. Understanding the location data safety risks this creates, and taking three minutes to change a few settings, can make an immediate difference.
This post explains what your location data reveals, who collects it, how it gets used against people, and what you can do about it right now.
What Your Location Data Actually Reveals
Most people treat location tracking as a minor convenience trade-off. The maps app needs to know where you are. That makes sense. What does not make sense is that hundreds of other apps are doing the same thing, with no obvious reason to.
Location data collected over time tells a detailed story. Your home address appears in the data every night. Your workplace, your doctor’s surgery, your children’s school, and your place of worship all appear regularly. The overall picture reveals your daily routine in enough detail that anyone watching would know exactly when your house is empty.
A single day of location data might seem harmless. One month becomes a profile. By the end of a year, it is a complete map of your life.
Companies collecting this data claim it is anonymised. Research has shown repeatedly that anonymisation does not hold. Movement patterns are distinctive enough that even a small number of location data points can identify a person individually.
Location data gathered for advertising is bought and sold. It surfaces in data broker databases. From there, it can reach people with very different intentions.
Who Is Actually Collecting Your Location
The answer is not just your maps app. It is a surprisingly long list.
Apps, carriers, and operating systems
Apps are the most visible source. When an app requests location permission, many people tap “allow” without a second thought. Weather apps, shopping apps, games, social platforms, fitness trackers, and news apps all commonly request location access, and many request it constantly, not just during active use.
Your mobile carrier knows your location at all times because of how phone networks function. Your device connects to towers, and those towers create a continuous record of where you have been. This data gets retained by carriers and, in documented cases, sold to data brokers and to law enforcement without a warrant.
Your phone’s operating system, whether iOS or Android, also collects location data for various services. Some of this appears in your settings. Some runs quietly in the background.
Data brokers: where your location data ends up
Data brokers collect location data from apps, aggregate it into detailed profiles, and sell access to anyone willing to pay. The Coalition Against Stalkerware has documented cases where abusive partners purchased real-time location data on their victims directly from data brokers, with no hacking required.
That is the key shift in understanding location data safety risks: if a company can buy your location, so can an individual who wants to know where you are.
When Location Tracking Safety Risks Become Physical
Location data becomes dangerous in two distinct ways: through commercial data reaching the wrong hands, and through targeted tools placed on a phone by someone you know.
Commercial data misused
The commercial route is less understood but more widespread. Avast’s security research team found that the number of people globally protected from stalkerware and spyware in 2024 more than doubled compared to pre-pandemic figures, representing a 228% increase since 2020. That means twice as many people were being monitored without their knowledge than just four years earlier. In documented domestic abuse cases, abusers accessed commercially collected location data to intercept victims at locations those victims had never shared with anyone.
Stalkerware and SIM swapping
Apps deliberately placed on a phone to monitor someone without their knowledge are called stalkerware. They run silently, transmit location in real time, and leave no obvious trace. Typically, a partner, ex-partner, or family member with brief physical access to the device installs them. The victim sees nothing unusual.
Approximately 1 in 10 people has experienced some form of tech-enabled stalking, according to the Coalition Against Stalkerware in 2025, with former intimate partners as the most common perpetrators.
SIM swapping is a related route. An attacker contacts your mobile carrier, impersonates you, and gets your phone number transferred to a SIM card they control. From there, calls get intercepted, two-factor authentication codes get captured, and location services tied to your account become accessible.
Your home address combined with your daily routine gives someone real power over you. This is why location data deserves the same protection as your passwords.

How to Reduce Your Location Data Safety Risks Right Now
You do not have to give up your phone. Being deliberate about what you allow takes about three minutes.
Step 1: Review your location settings today
On both iPhone and Android, you can see exactly which apps hold location permission and change each individually. The key move is shifting apps from “always on” to “only while using,” or turning location off entirely for apps with no clear reason to track you.
A recipe app does not need your location. Games do not need it. Shopping apps may use location for targeted ads, but none of them need it to function. Turn it off and see whether the app still works. In most cases, nothing changes.
On iPhone: Settings, then Privacy and Security, then Location Services. On Android: Settings, then Location, then App Permissions. Every app with access appears in the list with its current permission level shown.
Step 2: Enable a SIM PIN with your carrier
Check whether your carrier offers a SIM lock or account lock option. Since July 2024, the FCC has required all major wireless carriers to offer customers the ability to lock their accounts and block unauthorised SIM transfers. The FCC’s ruling on SIM swap and port-out fraud protection explains what carriers must now provide and what customers can ask for. Very few people know this protection exists, let alone that they have to switch it on themselves. Enabling it makes a SIM swap attack significantly harder to carry out.
Step 3: Check for monitoring software if needed
If you have any reason to believe someone placed monitoring software on your phone without your knowledge, the Coalition Against Stalkerware provides a step-by-step guide to checking for and removing stalkerware safely. Their guidance specifically accounts for safety risks during removal, which in some situations can escalate danger. Reading it before acting matters.

Frequently Asked Questions
Can I turn off location for apps without breaking how they work?
For most apps, yes. The majority request location access for advertising or personalisation, not because the core function requires it. Turn it off, use the app normally, and see whether anything stops working. If nothing does, the permission was never necessary.
How do I know if tracking software has been placed on my phone?
Watch for a battery draining faster than usual, higher mobile data usage than expected, and the phone running warm when idle. No single sign is definitive, but a combination of all three is worth investigating. The Coalition Against Stalkerware offers a free detection guide at stopstalkerware.org.
Does location data travel with photos when I share them?
Often, yes. Photos taken on a smartphone frequently contain GPS coordinates embedded in the file itself. Most social media platforms strip this before publishing. Sharing a photo directly, whether by email, messaging app, or file transfer, can send that location information along with the image.
Conclusion
The location data your phone collects is more revealing and more dangerous than most people realise. It is not just a record of where you have been. It is a map of your routine, your relationships, and your vulnerabilities.
Reducing your location data safety risks is one of the highest-impact privacy changes you can make today. Open your phone’s location settings and turn off access for every app with no clear reason to know where you are. The whole process takes under three minutes and immediately reduces how much of your daily life gets shared, sold, and seen by people you would never choose to tell.
If this was useful, share it with someone who needs to know.
