Cookies What are cookies?
Cookies are small pieces of data, stored in text files, that are stored on your computer or other device when websites are loaded in a browser.
They are widely used to ‘remember’ you and your preferences, either for a single visit (through a ’session cookie’) or for multiple repeat visits (using a ‘persistent cookie’).
They ensure a consistent and efficient experience for visitors, and perform essential functions such as allowing users to register and remain logged in.
Cookies may be set by the site that you are visiting (known as ‘first party cookies’), or by other websites who serve up content on that site (‘third party cookies’).
Cookies set by Jetpack
Cookies are used by Jetpack in a variety of different ways.
The cookies set will depend on the Jetpack features that are enabled. The cookies are only set when a user interacts with one of these, or to allow admin functions to be performed in wp-admin.
More details are in the tables below, which lists the cookies that are set for visitors and registered users of sites with the Jetpack plugin installed.

Some Jetpack features make use of third party applications and services to enhance the experience of visitors. These include social media platforms such as Facebook and Twitter (through the use of sharing buttons). As a result, cookies may be set by these third parties, and used by them to track your online activity. We have no direct control over the information that is collected by these cookies.
