The iPad uses Safari as the primary Web browser, so anyone familiar with Safari has an advantage. As you visit websites, your browsing trail is stored on your computer. Sites may also create cookies, which store information. For example, when you are at a shopping website, cookies remember what you select and put in the shopping cart. While they provide a service, they also take up space and may invade your privacy.
Click on "Settings" from the home screen of the iPad. The "General" category opens by default.
Scroll down the left pane and select the "Safari" category.
Tap either "Clear History" or "Clear Cookies and Data" to complete the task.
