Safari for iPhone and iPad will track your search history by default. For users that either share devices with other users or just don't want people nosing through their
porn browsing history - hey, we don't judge! - you can enable private browsing which won't track what you're doing and what sites you're visiting.
That's all there is to it. Now when you launch Safari, you will notice that the browser has a black interface instead of light blue. This indicates that private browsing is active. If you'd ever like to turn it off, you can do so by following the same steps above.
