Just as it's possible to enable private browsing in Safari for desktops, you can do the same using Apple's mobile web browser. If you know how to open an incognito window in Safari for iOS, you can prevent the app from saving your browsing history, cookies, or local user data.
Instructions in this article apply to the Safari app for iPhone, iPad, and iPod touch devices.
How to Enable Private Browsing in Safari for iOS
To browse incognito using the Safari mobile app:
Launch the Safari app and tap the Tabs icon, indicated by two overlapping boxes in the bottom-right corner.
Tap Private at the bottom of the screen.
Tap plus (+) to open a new tab. You are now in Private Browsing. Safari will not save any browsing history, cookies, or other user data during your session.
To return to standard browsing mode, tap Done at the bottom of the screen.
Pages that were visited during your private session close when you return to standard browsing mode, but any tabs left open will return the next time you open Private Browsing. To exit the pages permanently, tap the X in the top-left corner of the tab you want to close.
Private Browsing does not withhold data from your internet service provider or the websites that you visit. It only prevents information that is usually stored on your device from being saved.
