Free Isn't Free: How "Free" Apps Really Make Money From Your Data

Free apps pay their bills somehow. Here's how ad-funded apps turn your data into revenue, real cases from the FTC, and what to check before you upload anything.

"Free" is the most expensive word on the internet. Somebody pays for the servers, the engineers and the office lease behind every free app. If it isn't you, with a subscription, it's usually someone who wants to reach you — and the thing they buy is information about you.

That's not a conspiracy theory. It's a business model, and regulators have spent the last decade documenting how it works.

How a free app turns you into revenue

Most ad-funded apps make money in some mix of three ways:

  • Targeted advertising. The more an app knows about your income, health, family and habits, the more an advertiser will pay to put something in front of you.
  • Sharing with "partners." Data flows to analytics companies, ad networks and marketing platforms through code built into the app — often invisibly.
  • Data brokers. Companies whose entire business is collecting, combining and selling profiles of people. California alone lists more than 600 registered data brokers.

Real examples, from the public record

In 2023 the U.S. Federal Trade Commission took action against GoodRx, a prescription discount app. According to the FTC, GoodRx shared users' health information — including the medications people bought — with Facebook, Google and others, and used it to target ads. In one case it uploaded lists of people who had bought heart and blood-pressure medications. GoodRx paid a $1.5 million penalty.

In 2019 the FTC's record $5 billion settlement with Facebook included this detail: Facebook collected people's phone numbers for a security feature, two-factor sign-in, and the FTC said it didn't tell them those numbers were also used for advertising.

Notice the pattern. Neither case involved a dramatic hack. The data was handed over through ordinary business decisions, because that's what the business model rewards.

Why this matters more for documents than for photos

A vacation photo says something about you. A tax return, an insurance policy or a passport says almost everything: your income, your address, your health, your family, your signature. If you store that kind of paperwork in a free service, ask the obvious question: what is the service getting in return?

How to tell what you're really paying with

  1. Find the business model. If there's no price, look for how the company makes money. "Advertising" or "partners" means your data is part of the deal.
  2. Search the privacy policy for "sell," "share" and "advertising." Under laws like California's, companies have to disclose whether they sell or share personal information for advertising.
  3. Check whether your content trains AI. Many services now use what you upload to train their models unless you opt out.
  4. Look for an exit. Can you export everything and delete your account in a few clicks? Hard exits usually mean your data is worth keeping.

The honest alternative: pay with money, not with your life

A subscription is a simple deal. You pay; the company works for you. That's the model we chose for Unfoggable: your documents are read for one reason — to file them and remind you before something expires — and never sold, shared for anyone's marketing, or used to train AI. You can read exactly who handles your data in our privacy policy.

Free will always be tempting. Just remember that with your most important paperwork, "free" usually means somebody else is the customer.
