While other web browsers exist and thrive on iOS, Safari is the one Apple includes with it’s iOS system software, and it’s probably the one most of us use often, no small thanks to the fact that it’s integrated at the system level. Every click through, unless third-party apps (like Mailbox) allow something different, takes us to Safari as our main browser.
Therefore, if you’re looking for ways to protect more of your privacy, you’ll want to enable the Do Not Track feature in mobile Safari, as well as possibly block cookies, which are bits of code that store your preferences on website servers for return visits.
Do Not Track is a feature that needs the cooperation of advertiser tracking software on the web, but a little bit of possible privacy is still better than nothing.
Launch your Settings app with a tap, and then scroll down to tap on Safari. Once there, you’ll see the Privacy & Security section, about halfway down the screen. Tap on the toggle button to turn Do Not Track to ON. That’s all there is to it.
To block cookies, simply tap on the next section down, Block Cookies. You can then choose to block all cookies (Always), only from third-party sites and advertisers, or none at all (Never). Tap your choice here and then either tap back through the screens you went through to get here, or just hit the Home button.
To activate Do Not Track in Safari, open Settings and choose Safari. Press the toggle to the right of Do Not Track. To block cookies in Safari, select Block Cookies in Safari’s settings and choose either Always, or “From third parties and advertisers,” which is the setting I use.
Scroll down Safari’s settings to find two other privacy-enhancing options: Clear History and Clear Cookies and Data.
