What are cookies (on the internet)?

When you visit a website, a small pop-up appears before you explore it fully, asking you to “Accept all” or “Deny.” These are internet cookies often explained in tiny bits of texts we don’t bother to read.

In today’s digital world, where so much of our information exists online, it’s important to understand what happens when you accept or decline these cookies.

The concept

Internet cookies are tiny text files that store bits of data when you visit a website. They help the site remember who you are and what you like, such as your computer details, username, login info, language preference, or items in your shopping cart.

When you visit a website, its server creates a small piece of data called a cookie. This cookie carries a unique ID that belongs only to you and your computer. So, when you come back later, the website reads that ID, recalls what you did before, and adjusts your experience — like keeping your login active or showing items you left in your cart.

This helps websites offer a smoother and more personalised experience the next time you visit.

Why do we need them

Imagine visiting your favourite online game or store, and every time, you have to log in again or lose your progress. Cookies prevent that! They make your web experience smoother and faster by remembering your choices. They also help websites understand what users like, so they can improve features, show relevant content, or offer better recommendations the next time you visit.

Are they safe?

Most cookies are harmless, but it’s important to understand that they track your activity online in order to show you more relevant advertisements. That’s why websites ask for your permission to use them. As long as you’re visiting trusted websites and managing your cookie settings wisely, cookies are generally safe to use.

Enabling or removing

Now that you know what a cookie on the internet does, it’s up to you if you want to give access to it or not as its not all cookies are necessary — some are optional. You can manage your cookie settings anytime from your browser’s privacy or security section.

If you disable or remove cookies, your information is cleared, which helps protect your privacy. But the next time you visit a site, you may have to log in again or re-enter details.

It’s a good habit to clean up cookies once in a while to keep your data safe. For extra privacy, some people also use tools like a VPN (virtual private network) that hides their real location online.
