The Dark Side of Free Services—What You’re Actually Paying With
Ever wonder why services like Google, Facebook, Instagram, YouTube, and TikTok are free?
Because you’re not the customer—you’re the product.
If a service is free, it means you’re paying in other ways—usually with your data, privacy, and attention. Learn more about how to secure your online information in my article, Essential Cybersecurity Tips Everyone Should Know. If you’re concerned about online privacy, check out my article, The Truth About Online Anonymity (Are You Ever Really Invisible?).
This guide will break down how free services make money, what they track, and how to protect yourself.
Why Are Free Services… Free?
Companies don’t run billion-dollar businesses out of charity.
If you’re not paying for the product, YOU are the product.
How “Free” Services Make Money:
Ads: They collect your data and sell ad space based on your behavior.
Data Sales: They sell or share your information with advertisers & third parties.
Engagement Farming: They keep you scrolling so you see more ads.
Pro Tip: If a service relies on ads, their priority isn’t YOU—it’s keeping advertisers happy.
What Data Are You Giving Away?
Most free services track and collect far more than you realize.
Examples of What’s Being Collected:
- Location (even if you turn off GPS).
- Browsing habits (even outside their site).
- Private messages & search history.
- Face & voice data (apps like TikTok, Snapchat, and Alexa).
- Who you interact with (social media relationships, call history).
Pro Tip: Even if you delete a post, platforms keep data stored in their databases.
The Biggest “Free” Services and How They Make Money
- Scans your emails (Gmail) & searches to personalize ads.
- Tracks every website you visit (Chrome, Search, Maps, YouTube).
- Owns the world’s largest ad network (Google Ads).
Facebook / Instagram
- Collects everything (your likes, comments, messages, even mouse movements).
- Tracks your activity on other websites (Facebook Pixel).
- Uses AI to predict what you’ll click next and keeps you scrolling longer.
TikTok
- Collects biometric data (face & voice recognition).
- Stores data on servers outside the U.S., raising security concerns.
- Uses an aggressive algorithm to maximize engagement.
YouTube
- Recommends videos based on your watch time & behavior.
- Uses AI-driven ad targeting (your searches influence ads you see).
- Even if you never sign in, Google tracks what you watch.
Pro Tip: Even when you log out, these services can still track you through browser cookies and device IDs.
How to Minimize Data Collection
You may not be able to completely avoid data tracking, but you can limit exposure.
Use Privacy-Focused Alternatives:
- DuckDuckGo or Brave Search.
- ProtonMail.
- Firefox with privacy extensions.
Adjust Your Privacy Settings:
- Turn off ad personalization in Google & Facebook settings.
- Disable location tracking when not needed.
- Use a VPN to mask your IP address.
Be Mindful of What You Share:
- Avoid posting personal details publicly.
- Assume that everything you type, click, or say is being tracked.
Pro Tip: The less data you give away, the less these companies have to sell.
Nothing is Truly Free
“Free” services survive by selling your data.
- If you’re not paying with money, you’re paying with your privacy.
- You can’t avoid all tracking, but you can limit it.
- Think before you share—once data is out there, you can’t take it back.
Your privacy is valuable. Don’t give it away for free.
