You have probably never heard of the companies that know the most about you. Data brokers quietly collect your name, address, age, shopping habits and more, then package and sell it — usually without you ever clicking “agree.” Understanding how they work is the first step to taking back some control. Our GetMyPassword team explains what a data broker is, what they know, and what you can do about it.
What a data broker is
A data broker is a company whose business is collecting personal information and selling it to advertisers, marketers, other companies and sometimes anyone who pays. You are rarely their customer — you are the product. They operate in the background, which is exactly why most people have never heard their names.
What they know and where they get it
- Public records — property, voter and court records, and similar filings.
- Your online activity — sites you visit, apps you use and things you buy.
- Loyalty programs and surveys that quietly share or sell what you enter.
- Other brokers — they buy and combine data from each other into deep profiles.
Why it matters
Broker profiles feed targeted ads, spam and robocalls, but the risks go further. The same data helps scammers craft convincing phishing, lets stalkers and doxxers find your address, and exposes details a criminal can use to answer your security questions. The more of your life sits in these databases, the bigger your attack surface.
When a service is free, your data is often the price — and data brokers are who it is sold to. You were never asked, because you were never the customer.
What you can do
You can fight back. Many brokers offer an opt-out page — find it and request removal, or use a service that handles removals for you. Share less by tightening app and account privacy settings and being stingy with surveys and loyalty forms. And reduce what leaks in the first place: give every account a unique password from our password generator and turn on two-factor authentication, so a breach cannot hand brokers and criminals even more of your data.
Frequently asked questions
Is what data brokers do legal?
In many places, yes — collecting and selling personal data is largely legal, though privacy laws in some regions give you rights to access or delete it. Where those rights exist, brokers must honor valid removal requests.
How do I get my data removed from data brokers?
Find each broker’s opt-out or removal page and submit a request, repeating for every site. Because data reappears over time, recheck periodically, or use a paid removal service to automate it.
How is a data broker different from a search engine?
A search engine indexes public web pages; a data broker actively compiles personal profiles from many sources and sells them. Brokers package details about you specifically, rather than just linking to existing pages.
