When you visit any web site, it may store or retrieve information on your browser, mostly in the form of cookies. This information might be about you, your preferences or your device and is mostly used to make the site work as you expect it to. The information does not usually directly identify you, but it can give you a more personalised web experience.
Without cookies, a website is like a goldfish who loses its memory every time you visit a new page. Once you visit a new page, it doesn’t remember who you are.
Now this can be a good and a bad thing. Without any memory, a website can’t do a lot of stuff. It can’t let you log in, because it forgets who you are. It can’t let you buy anything, because it forgets what you’re buying.
A better option would be to turn off 3rd party cookies, which will stop most websites from sharing information about you.
And finally, you can take a deeper look into any websites which concern you. Most websites have policies that explain what they do, if you care to look.
Well over 90% of websites use cookies. Cookies aren’t automatically good or bad, but it’s worth understanding what you can do about them.
