Here's how to go incognito on your iPhone:
Using Safari:
Open the Safari app on your iPhone.
Tap the Tabs button. It looks like a square with a stack of squares in the bottom right corner of your screen.
Swipe right on the tab bar at the bottom of the screen until you see the "Private" option. You might need to swipe multiple times depending on how many tabs you have open.
Tap "Private". This will open a new window for private browsing. Any websites you visit in this window will not be saved in your browsing history, cookies, or search history.
To exit incognito mode, simply tap the Tabs button again and tap the "X" on the top left corner of the private window.
