In this fast-going world, data privacy is the primary concern; we will discuss the details about cookies and how to delete cookies, cache, and history from your iPhone. But first, we need to know what cookies are and their different types. How do they work? Are they beneficial or harmful?  

What are cookies? 

It’s not a baked-sweet thing you ate as a dessert. We are talking about small data files. Whenever you visit a website, it downloads some small text files on your device. It helps websites to remember you when you visit the next time.

How do cookies work? 

Cookies are small pieces such as username, password, or search history. When cookies are exchanged between a website and your server, it acts as an id code by which the website knows that you have visited before. It also aids websites to know what precisely to show you according to your last visit.

Types of cookies: 

  1. Magic cookies; are small packets of information to store your username and password, so you don’t need to enter your password again and again. This type of cookie cannot be changed when sent and received. 
  2. HTTP cookies; these cookies help to make your browsing experience better. This cookie enables the online shopping experience more smoothly, and website servers don’t get overloaded.  

HTTP cookies are also of different types.

Session cookies; help navigate the website, and as the name indicates, these cookies are deleted soon after the session. Session cookies help the back button and third-party analyzer plugins to maintain the user’s privacy.

Persistent cookies; remain on the device for the longest time, although they have an expiration date after they are automatically deleted. Websites use these cookies to see if they are logged in and remember their id password. Also, they have the data about how many times per user has visited and their preference on the website.

Are cookies useful? 

Websites use cookies to streamline the browsing experience. Your bank will use cookies to remember your login username and password; your shopping website will remember your cart, so you don’t have to start from scratch. We will discuss how these cookies are used;

  1. Management of session: because of the cookies, the website recognizes the person, it personalizes the feed according to the last visit. E.g., political versus sports news.
  2. Personalization: cookies attract the ads related to the person’s interest. Targeted ads are displayed on the website which the person will like. 
  3. Tracking: shopping websites will use cookies to remember what you bought last time. This will help them know the items they liked and suggest more during the session.

Cookies can be dangerous: 

Although cookies personalized the browsing experience, they can also be a threat. Cookies themselves are not harmful, and the website cannot transfer viruses through, but if hackers get access to cookies, they can quickly go through your browser and see all the data and history. So many people will instead enter the details repeatedly rather than getting spied on by hackers.
