Private browsing, also known as incognito mode, lets you surf the web without storing your browsing or search history. Here's how to quickly turn private browsing on or off in Safari.
It's worth noting that private browsing won't disguise you from the sites you visit. They could still record your IP address and any information you enter into their sites, such as search terms. Additionally, private browsing won't protect you from web-based malware attacks, so you'll still need to be careful about what you click on whether you're in private or normal browsing mode.
Private browsing mode is helpful when you don't want other users to discover (accidentally or not) the sites you've been looking at. Apple iCloud syncs your browsing history between the Mac and the iPad and iPhone, so if you share devices, you can protect your privacy with private browsing mode. This also comes in handy if you're using a public computer and don't want to leave any AutoFill information behind.
