We use cookies for a number of different purposes. Some cookies are necessary for technical reasons; some enable a personalized experience for both visitors and registered users; and some allow the display of advertising from selected third party networks. Some of these cookies may be set when a page is loaded, or when a visitor takes a particular action (clicking the “like” or “follow” button on a post, for example). Many of the cookies we use are only set if you are a registered WordPress.com user (so you don’t have to log in every time, for example), while others are set whenever you visit one of our websites, irrespective of whether you have an account. For more information on the choices you have about the cookies we use, please see the Controlling Cookies section below.

We set cookies in a number of different locations across our services. These include: On our websites (including automattic.com, wordpress.com, vip.wordpress.com, jetpack.com, woocommerce.com, crowdsignal.com, gravatar.com, intensedebate.com, vaultpress.com, akismet.com, simplenote.com, simperium.com, leandomainsearch.com, cloudup.com, longreads.com, and happy.tools). In the administrative dashboards of our websites, such as Calypso and wp-admin. On sites we host for our users. On sites that use our plugins (e.g. Jetpack). In the emails we send.

Required These cookies are essential for our websites and services to perform basic functions and are necessary for us to operate certain features. These include those required to allow registered users to authenticate and perform account-related functions, store preferences set by users such as account name, language, and location, and ensure our services are operating properly. Analytics and Performance These cookies allow us to optimize performance by collecting information on how users interact with our websites, including which pages are visited most, as well as other analytical data. We use these details to improve how our websites function and to understand how users interact with them. Advertising These cookies are set by us and our advertising partners to provide you with relevant content and to understand that content’s effectiveness. They may be used to collect information about your online activities over time and across different websites to predict your preferences and to display more relevant advertisements to you. These cookies also allow a profile to be built about you and your interests and enable personalized ads to be shown to you based on your profile.

In addition to the cookies set on our own sites, we utilize cookies for our Site Stats feature. This tallies the unique numbers of visitors to a site, as well as the number from specific geographic locations. A visitor is counted when we see a user or browser for the first time in a given period. Examples Below are examples of the cookies set by Automattic, with explanations of their purpose. Some of these cookies are set across our whole network, whereas some are specific to individual services (e.g. WordPress.com, Longreads, etc). Please note that this is not an exhaustive list, but rather aims to be representative. Information about cookies that may be set by third parties, such as our ads partners, is below. Additionally, we occasionally set referrer cookies on Jetpack connected sites, using WooCommerce. In addition, people and companies that use our services to publish or host their own sites may place additional cookies. We provide more information on these cookies below.
