Your browser creates a lot of temporary files during normal internet browsing. The cache refers to files of website elements — like images, videos, text, and more — that your browser downloads and stores in case you return to the same website again. Then, if you do return, your browser can load those elements from the cache, which saves time. But if you never view that particular site again, your browser has no use for those cache files. When you consider how many social media sites, e-shops, and other pages with lots of graphics you visit on a daily basis, you’ll realize just how much useless cache data your browser has stored.
Cookies are a bit different. They keep track of who you are and what you do on a site. Cookies are what enable a website to remember that you’re logged in, or what your preferred language is. Tracking cookies are a specific type of cookie that third parties use to follow you around the web, log your browsing habits and other online behavior, and then sell that data to advertisers or other interested parties. We recommend clearing out tracking cookies regularly to protect your privacy.
