Just like any other web browser, Safari also keeps the history of whatever you search. Whether they are cookies, logins or website data, the stock web browser for iOS keeps all of them in order to help you access these data easily.
There are two prime reasons why you should clean up Safari history from time to time. While one reason could be to prevent others from checking out what you search, the other purpose may be to stop the web browser from being chaotic.
Whatever could be the reason, it's better to clean up the unnecessary data regularly. (Make sure to check out this post to Clear Safari History and Website Data on iOS 9.)
