How to Use Private Browsing on Your iPhone
Don’t want to leave any tracks while you surf on your iPhone? Turn on private browsing for a “what happens in Safari stays in Safari” tool. Those truly bent on staying private will also want to tap Clear History and Website Data.
To go incognito, tap Bookmarks so that you see a tabbed view of open pages, and then tap the Private button, in the bottom-left corner. You’re given the option to close your existing tabs before turning on private browsing.
After private browsing is on, any traces of your visit to nonono.com (or wherever) are nowhere to be found. With iOS 8, you can now go private on tabs representing what you consider to be your most sensitive cyberdestinations, without having to go private while you browse sites that are more innocuous.
Your history is wiped clean, open tabs don’t appear in iCloud Tabs, and your AutoFill information is not stored anywhere. To remind you that you’re browsing privately, the Safari interface takes on a darker shade — a not so subtle message here, that you might be engaging in a shady or naughty activity. Maybe, you’re just a private soul, and that should be respected.
To return out of hiding, tap the bookmarks icon and then tap Private again.
