You've probably never heard of the companies that know the most about you. Data brokers quietly collect, package and sell your personal details — and most people have no idea they exist, let alone that you can tell them to stop. Here's the plain version, including the free way to do it yourself.
Who data brokers are
A data broker is a company whose entire business is buying and selling information about people. They pull from public records, store loyalty schemes, app trackers, online forms and other brokers, then build a profile of you — name, address, age, household, rough income, interests, the lot — and sell it to advertisers, marketers, and sometimes anyone who'll pay. You never agreed to most of it; it just accumulates.
Why it's worth caring about
- Scams and fraud. The more that's known about you, the more convincing a scammer can be — those “they knew my name and address” calls start here.
- Spam and cold contact. Sold-on details are why the junk mail and unknown callers never quite stop.
- Profiling. Decisions get made about you — what you're shown, what you're offered — based on a profile you never saw and can't check.
How to opt out yourself — for free
You can absolutely do this without paying anyone, and we'll always say so. In the UK you have data-protection rights that let you ask a company to delete what it holds on you:
- Identify the brokers (a search for your name, address and phone number is a sobering place to start).
- Send each one a deletion / opt-out request — most have a privacy or “your data” page, and they're legally obliged to act.
- Keep a record, and chase the ones that drag their feet.
It works. The catch is that it's tedious and never finished — there are dozens of brokers, and your details quietly reappear as data is re-bought and re-sold. It's a chore you have to repeat.
When a removal service is worth it
Because it's an ongoing slog, some people would rather pay a service to do it on repeat — submitting and re-submitting removal requests across the brokers, month after month. The one we rate is Incogni; it's on-brand (it's literally taking your data back) and it's a recurring subscription, so we'll be straight that we may earn a commission if you sign up through us. You can see that marked openly alongside everything else on our tools page.
Either route is valid. Do it yourself and keep your money, or pay to never think about it — just don't let anyone tell you it's the only option, because it isn't.
And the bigger picture
Opting out of brokers tackles the data that's already out there. Stopping fresh data leaking from your phone in the first place is the other half — that's what de-Googling is for. Do both and you've genuinely taken back control of the tap and the bucket.
