What cookies are
Cookies are files created by websites that 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 two types of cookies:
- First-party cookies: Created by the site that you visit. The site is shown in the address bar.
- Third-party cookies: Created by other sites. A site that you visit can embed content from other sites, for example images, ads and text. Any of these other sites can save cookies and other data to personalise your experience.
Delete all cookies
Important: If you delete cookies, you might get signed out of sites that remember you, and your saved preferences could be deleted. This applies any time a cookie is deleted.

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 personalise 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.
You can find the full list of companies who define groups of related sites on Github. Learn more about related sites and third-party cookies.

Manage your tracking protections
When turned on, Tracking Protection significantly limits sites from using third-party cookies to track you as you browse, except for limited cases to allow basic services to function. If you choose to, you can block third-party cookies completely in your settings. You can manage your Tracking Protection preferences in your 'Privacy and security' settings.
- On your Android device, open Chrome
- At the top right, tap More
- Tap Privacy and security
- To customise your tracking protections, you can:
- Block all third-party cookies: when you toggle this on, features on some sites may not work. Chrome blocks all third-party cookies from sites that you visit, including related sites.
- Send 'Do Not Track' request with your browsing traffic: when you toggle this on, you request that sites not track you. Sites use their discretion whether to comply with the request. Learn more about 'Do Not Track'.
- Choose which sites you allow to use third-party cookies: You can also check and edit which sites you allow to use third-party cookies under 'Sites allowed to use third-party cookies'. Learn how to allow third-party cookies.
