Internet cookies weren’t created with sinister intent, but the way they work bothers some people nonetheless. An HTTP cookie is a short text file created by a website but stored on your computer that contains a bit of information about you.

The most common cookies include your login data (username and password) that allows for quick access to an account (think Netflix or PayPal), a list of your past search history that can make a shopping experience more efficient (Amazon), or the images featured on a certain website you visit frequently, allowing for quicker loading the next time you click through.

Cookies are the reason online ads are often oddly specific to you; they are one source that helps advertisers tailor the advertisements served to you based on your past web history. And they also make your potentially sensitive data, like a password, more readily accessible to other parties.

The good news is that clearing cookies on a Safari, a Mac computer’s default browser, is a quick process, and you can also manage how you are tracked in the future from individual sites.

Just know that if you do clear out all your cookies, many websites will take longer to load the next time you visit them, and you will have to reenter much of our login information. And note that websites will start in building new cookies right away unless you have opted to block them.
