That's especially true on a mobile device like the iPhone. Safari, the web browser that comes with the iPhone, gives you the power to change its settings and take control of its security. We'll show you how to use these features (this was written using iOS 11, but the instructions are fairly similar for older versions, too).

From your browsing history to cookies and more, you may not want to leave those tracks behind you. If so, you should use Safari's Private Browsing feature. It prevents Safari from saving any information about your web browsing—history, cookies, other files—while it's turned on.

If not, there are a few features you should enable. Tap Settings.Tap Safari.Move the Prevent Cross-Site Tracking slider to on/green.Move the Ask Websites Not to Track Me slider to on/green. This is a voluntary feature, so not all websites will respect it, but some is better than none.
