Private Browsing vs VPN - What's the Difference?
Private browsing (Incognito mode) and VPNs are both marketed as privacy tools, but they protect against very different threats. Using Incognito when you actually need a VPN is a common mistake that leaves your real IP address, ISP activity, and network traffic fully exposed.

What Private Browsing Actually Does
Private browsing prevents your browser from saving your history, cookies, site data, and form inputs to your device. When you close an Incognito window, all of that disappears from your local machine. That's it - It does nothing to protect you on the network.
- Your ISP still sees every website you visit (by IP and DNS)
- Websites still see your real IP address and can track you by browser fingerprint
- Network administrators can still monitor your activity
- Google still tracks your searches if you're signed in
