The incognito icon—a small grey figure in a hat, or a pair of sunglasses depending on your browser—has become shorthand for internet privacy. Open an incognito window and you feel, somehow, less visible. More protected. As if the hat and glasses extend to you, the user, rather than remaining the browser's own little costume.
This feeling is the product of a fundamental misunderstanding about what incognito mode does. It is not a privacy tool in any meaningful sense. It is a local history cleaner. And conflating the two has real consequences.
Incognito mode means your browser won't save your history on your device. It does not mean no one else is saving it. The websites you visit, your internet service provider, and your employer's network can all still see exactly where you've been.
What Incognito Actually Does
When you open a private or incognito window, your browser does three things: it doesn't save your browsing history to your device; it doesn't carry over cookies from your regular session; and it deletes any new cookies when the session ends. That's the complete list. What it doesn't do: hide your IP address from websites you visit. Prevent those websites from logging your visit. Stop your ISP from seeing your traffic. Conceal your activity from your employer if you're on a work network. Block tracking pixels or browser fingerprinting—the technique by which websites identify you based on the unique combination of your browser version, screen resolution, and dozens of other technical characteristics that remain constant whether or not you're in incognito mode.
In 2024, Google settled a $5 billion class action lawsuit alleging that Chrome's incognito mode had misled users into believing their browsing was private when Google was still collecting data through analytics tools embedded in third party websites.
What Actually Provides Privacy
If genuine privacy is what you need: a reputable VPN to mask your IP address; a privacy focused browser like Firefox or Brave with tracking protection enabled; a search engine like DuckDuckGo that doesn't log queries. Use incognito when you want to look at a gift without it appearing in your history, or when you want a clean session without your saved logins. Don't use it when you need actual privacy. Those are different jobs—and treating them as the same is how people get caught.
