Cookie pop-ups and banners are now seen everywhere on the web, thanks to data protection laws like the GDPR and CCPA. But, do you know how cookies are set when you interact with them? Do you know how to check cookies that are set on your browser? This blog will tell you how.

Cookie consent banners that are compliant with the privacy laws usually nudge at the following user response:

  • No interaction with the cookie banner
  • Accept cookies
  • Reject cookies
  • Set cookie preferences

So, what happens as a result of each of these actions. What happens when you accept cookies? What happens if you reject cookies? Or what happens if you ignore the cookie banner and continue browsing?

How do cookies work?

Cookies allow websites to store information on your device and retrieve it later. This information is labeled with an ID that is unique to your device. The next time you visit the website, the server knows what information is needed to specifically cater to you.

Usually, websites place cookies to remember certain information about you — what’s in your shopping cart or your login details and preferences, etc. Cookies are also used to streamline your web experience, for targeted advertising, tracking, and so on. 

So, how do you check cookies set on your browser? Open any website and right-click on the site and select Inspect to open the developer console.

Inspect> Applications > Storage> Cookies

Developer console with list of cookies, value, domain, expiry date etc.

Let’s understand what these terms mean.

  • Value is a randomly generated ID that is unique to your device. Here, the attributes ‘yes’ or ‘no’ indicate if the cookie has been set.
  • A domain is the name of the website server that created the cookie.
  • Expires or expiration date is the maximum age of the cookie i.e. how long your browser can use the cookie information to access the website.

What happens if you don’t interact with a cookie banner?

Most often, users tend to ignore cookie banners and continue using a website. So, are cookies then set on your device even when you haven’t given consent? Simply put, yes some cookies are stored in your device.

These are the strictly necessary cookies that are exempt from seeking explicit consent from the user, under both the GDPR and ePrivacy Directive (or the ‘cookie law’).

You can see that the website has loaded three cookies – cookieyesID, cookieyes-necessary, and cky-active-check. 

But how do you know if a website has only set the necessary cookies? On the CookieYes website, you can simply click on the ‘Cookie Settings’ tab, as you’ve seen in the interactive banner. You’ll see the category of cookies used by the website. You can see that the cookies set on your browser are necessary cookies that are required for the website to function properly. 

To check cookies used by any website, head to the Privacy Policy or Cookie Policy page (usually found on the website footer) and see the complete list of all the cookies deployed by the site.

What happens if you accept cookies?

When you accept all cookies, a lot more cookies are set on your browser. These include functional cookies, analytics, and advertising cookies.

The ‘other’ cookies that are set on the website are cky-consent and sib_cuid. cky-consent is used to remember the user’s consent preferences, so that the next time a user visits, the website remembers their choice. Sib_cuid cookies collect information on the user’s website navigation and preferences and are set by SendinBlue.

What happens if you reject cookies?

Four cookies are still enabled even when you don’t accept cookies. As we have previously seen, cookieyesID, cookieyes-necessary, and cky-active-check are necessary cookies and they will be stored in your browser whatever course of action you take about cookie banners. 

The fourth cookie that is enabled is cky-action, which is deployed to remember the user’s consent to the use of cookies on the website.

What happens when cookies are set on your browser? 

Cookies serve different purposes according to the function it is set for. To better understand what happens as a result of your interaction with cookie banners, let’s take a look at an e-commerce website like For instance, let’s say you set the cookie preferences to accept targeting cookies.

Should I disable cookies on my browser?

You’ve now seen how to check cookies set on your browser for each use case. You also know that some necessary cookies get stored on your website irrespective of how you interact with the cookie banners. Some websites may also not have cookies banners that ask for your consent, which means they drop cookies on your browser without your knowledge.

Clearing your cookies will log you out of websites that you regularly use, delete your saved passwords, search predictions, shopping cart information, site preferences, etc.
