What is Cached Data?

Cached data is information such as files, images, scripts, code, and links from a website or app stored on your computer. The cache is created the first time you visit the site or access the app. It reduces the time required to load the website or app the next time you access it.

How Does Caching Work?

You are likely familiar with web browser cache even if you didn't know the technical words for it. When this cache is created for a website, the information is stored in your computer's physical memory. There is a portion of your computer's memory called CPU cache that is dedicated to storing and retrieving information quickly.

Should You Clear Cached Data?

Your browser can store your history indefinitely. While having your browsing activities at your fingertips might be handy, it also means anyone with access to your computer or mobile device can readily see your history. Privacy and security are important to all of us.

Clearing your browsing history regularly is the prudent thing to do.
