Sites you visit can embed content from other sites, for example images, ads, text, and even features — like a text editor or weather widget. These other sites can ask for permission to use info they’ve saved about you (often saved using cookies) in order for their content to function properly.

For example, imagine you normally compose documents on `docs.google.com`

. While completing a task for school, you need to collaborate with other students on your school’s class portal that offers direct access to Google Docs. With your permission:

- Google Docs can access its third-party cookies while you use your school’s site, allowing a connection between the site and Google Docs.
- This may allow Google Docs to verify who you are, find your info, and save changes you make to your documents on the site.

In some cases, this info can be used to track your activity as you browse sites. As a privacy feature, you can decide when to allow embedded content to access your data for sites you trust.

**Tip:** The connection uses cookies and lasts for 30 days or as long as you remain active. You can stop allowing the connection anytime in Settings.

#### To allow or decline permission

When you browse a site that displays a prompt requesting for permission for the embedded content to use information they’ve saved about you:

- Select
**Allow**to give the site access to information they’ve saved about you (using cookies) - Select
**Don’t allow**to deny access

**Tips:**

- To stop allowing access, learn how to manage site settings permissions.
- You can also manage access by clicking View site information to the left of the address bar, and then turning
**Embedded content**on or off.
