LinkedIn Cookie Table
Last Updated: May 15, 2024
We use different types of cookies to collect and use data as part of our Services.
We use two types of cookies: persistent cookies and session cookies. A persistent cookie lasts beyond the current session and will stay on your browser until they expire or you delete them. Session cookies last only as long as the session (usually the current visit to a website or a browser session). Third parties, such as our customers, partners and service providers may also use cookies in connection with our Services. Please take a look at our Cookie Policy if you’d like more information on how and why we and third parties use cookies. You can also find more information in our Privacy Policy, including information about how we process data collected through cookies.
These tables list some of the cookies that we and third parties place. In addition to cookies strictly required for providing our services, they include information about the cookies that LinkedIn uses on third party sites including when LinkedIn’s Insight Tag is installed on our customers sites. The tables also provide information about the cookies that third parties may use to help us to provide our Services.
Since the number and names of cookies may change, these tables may be updated from time to time to provide you with the latest information. The expiration dates for the cookies listed below generally apply on a rolling basis.
