Can I make Incognito a default mode on iOS?
Unfortunately, you can’t make incognito a default mode on the iPhone. That said, you can stop cookies from tracking you, even if you’re using a non-private window. For this, head to Settings > Safari > Privacy & Security and turn ON Block All Cookies. This will also enable the Prevent Cross-Site Tracking option automatically. Also, tap Hide IP Address and select From Trackers.
