You can choose to delete existing cookies, allow or block third-party cookies, and set preferences for certain websites.

Cookies are files created by websites you visit. By saving information about your visit, they make your online experience easier. For example, sites can keep you signed in, remember your site preferences, and give you locally relevant content.

There are 2 types of cookies:

• First-party cookies: Created by the site you visit. The site is shown in the address bar.
• Third-party cookies: Created by other sites. A site you visit can embed content from other sites, for example images, ads, and text. Any of these sites can use third-party cookies to personalize content and ads, and learn about actions you take on other sites.

There are other ways that sites can personalize content and ads. Features like ad topics and site-suggested ads in Chrome allow sites to show you personalized content. These features limit what sites and their partners can learn about you. Learn more about managing these features.

A company can define a group of sites that are related to each other. For example, a company might want to keep you signed in as you move between acme-music.example and acme-video.example.

• If you allow third-party cookies: Allows related sites to access your activity to personalize content or keep you signed in across sites.
• If you block third-party cookies: It often prevents this kind of connection between sites. You can block third-party cookies while you allow sites in the same group to improve your experience.
