8 Places Where Your Personal Data Is Sold This Week

Somewhere right now, your name, photo, phone number, and address are being scraped, sorted and sold like socks in a clearance bin. Sometimes it gets used for ads, other times it lands on a stranger’s checklist. Legally speaking, you’ve probably consented to it, even if it was just a checkbox you ticked without thinking.

Either way, it’s already out there, but just because it is circulating doesn’t mean you can’t put up a few barriers and at least limit the damage.

These are the places where your information ends up, how it’s exploited, and what that means for you.

1 People search and identity sites

These are some of the most common places where personal data gets sold or shared without people realizing it. They quietly pull information about individuals from public records, commercial databases, and third-party brokers, then package it into neat profiles that are searchable by name, phone number, email address, etc. A single search can reveal your age, past and current addresses, phone numbers, email addresses, relatives, and sometimes work history or property records.

Some of the well-known companies in this space include Whitepages, Spokeo, BeenVerified, Radaris, and TruthFinder. This might be the first time you are hearing these names, but the chances of your information already being listed on at least one of them aren’t zero. And if you are a US citizen, you might be more searchable than cat videos on the internet.

In June 2025, a man accused of killing Minnesota State Representative Melissa Hortman and her husband, and shooting another lawmaker and his wife, reportedly used people-search sites to find their home addresses. Prosecutors found notebooks listing 45 officials and the data broker websites he used. Imagine your personal info being handed to someone like this with no warning. One minute it is a marketing database, the next it is part of a criminal’s to-do list. (Source: Wikipedia)

2 App and location data aggregators

Weather apps, shopping apps, social media, and even free flashlight apps quietly watch where you go and what you do. They track your GPS location, how long you stay at certain places, and the routes you take. Companies like Foursquare, Cuebiq, Safegraph, X-Mode, and Placer.ai collect all this information, bundle it, and sell it to advertisers, marketers, and other data brokers.

In 2022, the FTC sued data broker Kochava for collecting and selling location data from hundreds of millions of mobile devices without consent. It was revealed that the data was so accurate that it could pinpoint visits to hospitals, reproductive health clinics, places of worship, and political rallies (FTC). Anonymization doesn’t really help in this situation, as it is surprisingly easy to re-identify. You can read this post for details.

3 Dark web and underground markets

The dark web is full of things you don’t want to think about, so if your personal data lands there, trouble is not far behind. Stolen Social Security numbers, credit card info, login credentials, and even medical records are routinely bought and sold for just a few dollars each. Victims can face identity theft, bank fraud, phishing attacks, credit rates, and a never-ending parade of things that make you wish the internet came with a warning label unless you freeze your credit, watch your accounts like a hawk, or hide out in a cabin with no Wi-Fi and a very convincing beard.

4 Behavioral profiling and analytics syndicates

These systems quietly build a psychological profile of you by tracking how you browse, what you buy, what you hesitate on and even what time of day you are most likely to give in. This data is collected through cookies, trackers, pixels, SDKs and cross-device fingerprinting, then stitched together to predict your habits and weaknesses.

These profiles are not just for ads. They are used to guess how desperate, emotional, or risky you might be. That can affect the loans you see, the insurance offers you get, the political content you are shown, and even the news pushed into your feed. It is less “the internet knows you” and more “the internet knows when to exploit you.”

5 Employment and background check data aggregators

When you apply for a job, it’s not just HR looking at your resume. There is an entire network of background check companies that pull court records, credit files, past employers, education records and even social media post to build a report employers rely on. Firms like HireRight, Checkr, and Sterling do this quietly, and once your info is in their systems it can follow you from job to job.

Even worse is that these profiles are often wrong. In late 2024, a job candidate in Maryland sued Sterling after its report falsely said she had a criminal history and even an active arrest warrant. She was lucky enough to know about the error before it cost her, but many others are not so fortunate.

6 Automotive and telematics data markets

A normal modern ICE car collects 1–5 GB/day, while a self-driving car collects a staggering 5–20 TB/day. For reference, whole data center servers collect 1–10 TB/day, and a heavily used smartphone collects 2–8 GB/day. GPS, cameras, radar, sensors, infotainment systems, and connected apps all feed into this, tracking location, routes, speed, braking, media use, and vehicle diagnostics.

Companies like Geotab, Octo Telematics, Verisk, and LexisNexis Risk Solutions collect this data to sell insights to insurers, marketers, fleet managers, and anyone else willing to pay. Insurers can peek at your late-night joyrides, advertisers know what gas stations you favor, and fleet managers can tell if your company car is moonlighting as a racecar on weekends.

Some drivers have seen their insurance rates double after telematics programs flagged “risky” driving, Fleet data leaks have exposed employees’ locations in real time, and advertisers have targeted people based on where they park, shop, or eat. In extreme cases, self-driving car logs have even been subpoenaed in legal cases to reconstruct accidents. Every turn of the wheel, every stop, and every lane change can now affect your wallet, your privacy, and occasionally your stress levels.

7 Credit and financial data markets

Every time you take out a loan, open a credit card, miss a payment or even apply for a store card, your data is being logged, scored and shared. Companies like Experian, Equifax, TransUnion and CoreLogic collect this data along with public records like bankruptcies, judgments and liens, then sell it as risk profiles to banks, insurers, lenders and even landlords.

So, these profiles are basically what decide whether you can get a loan, the interest rate you pay or if you can rent that cute apartment with the hardwood floors.

But according to FTC report roughly 20% of such consumer reports contain errors. That could be just a minor spelling error but it can also be something like a misreported late payment in which case you end up paying for a mistake you never made. You could dispute these errors by requesting your report, providing proof and having the bureau correct it which is ironic, because you’re essentially correcting a system that’s been quietly judging you without your consent.

8 Health and genomic data exchanges

Since the early 2000s, when governments began pushing for electronic health records, your medical info started moving from paper files to digital networks. Every doctor visit, lab result, prescription, or test became part of a system that’s easier to share and sell.

Much of this was sold to us as “helping science and curing diseases,” but it has mostly become a free pass for companies to treat your most personal information like a commodity. You can read more about this issue here.
