Private and Incognito Browsing Explained
What private browsing mode actually does, what it doesn't do, and when to use it
Every major browser has a private browsing mode. It goes by different names — Incognito, Private, InPrivate — but they all do roughly the same thing. The problem is that most people think it does far more than it actually does.
When you open a private window, the browser creates a temporary session that's isolated from your normal browsing. When you close that window:
- Browsing history from that session is deleted
- Cookies and site data from that session are deleted
- Form data and searches from that session are deleted
- Cached files from that session are deleted
That's it. It's a local cleanup tool. It prevents the next person who uses your computer (or anyone looking at your browser history) from seeing what you did in that session.
Frequently Asked Questions
Does private browsing make me anonymous?▾
No. Websites still see your IP address, your browser type, screen resolution, and other details that can identify you. Your ISP logs every domain you visit. Private browsing only prevents your browser from saving history and cookies locally.
Can my employer see what I do in Incognito mode?▾
Yes. If you're on a company network or a company-managed device, your employer can monitor your traffic through the network, DNS logs, or device management software. Private mode has no effect on network-level monitoring.
Should I always browse in private mode?▾
No. Private mode disables useful features like saved passwords, browsing history, and cookie-based logins. You'd have to sign in to every site every time. Use it when you have a specific reason, not as your default.
What's the difference between private browsing and a VPN?▾
Private browsing controls what your browser saves locally. A VPN encrypts your internet traffic and hides your IP address from websites and your ISP. They solve different problems and can be used together — a VPN for network privacy, private mode for local cleanup.
Do private browsing tabs share cookies with each other?▾
In most browsers, yes — tabs within the same private window share a temporary cookie jar. Safari is the exception: starting with Safari 17, each private tab is isolated. In all browsers, private tabs never share cookies with regular tabs.
