Incognito hides history from your device, not the internet
Private browsing changes what your browser saves on the device after a session. It generally won’t add the pages you visit to the browser’s history or keep its session cookies once you close the private window. That can help keep your browsing out of sight from someone who later uses the same device.
But a website still has to receive your request to show you a page. The site can see the connection and may record information such as your IP address, the network address that can help identify where a request came from. Websites can also recognize you if you sign in, and may use other tracking methods while you browse.
The network can still see the connection
Your internet provider—and, on a work or school network, the organization managing that network—may be able to observe connections to websites. Incognito mode does not encrypt your traffic or make you anonymous. HTTPS encrypts information sent between your browser and a website, but it does not necessarily conceal which site you connected to from the network carrying that traffic.
Incognito is mainly a privacy setting for the browser on your device, not a cloak for your activity online. Close the window and you may erase local traces; records held by websites or network operators are a separate matter.
