Our Privacy Policy explains our principles when it comes to the collection, processing, and storage of your information. This policy specifically explains how we, our partners, and users of our services deploy cookies, as well as the options you have to control them.

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 third parties, such as those who serve content or provide advertising or analytics services on the website (“third party cookies”).

Both websites and HTML emails may also contain other tracking technologies such as “web beacons” or “pixels.” These are typically small transparent images that provide us with statistics, for similar purposes as cookies. They are often used in conjunction with cookies, though they are not stored on your computer in the same way. As a result, if you disable cookies, web beacons may still load, but their functionality will be restricted.

How we use cookies

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.

Where we place cookies

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, gravatar.com, intensedebate.com, vaultpress.com, and akismet.com).
  • 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).

User Sites

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.

Advertisements from Third Parties Through Automattic’s Ads Program

Our mission is to democratize publishing. So that we can offer free access to create a website using WordPress.com, we show ads on some of our users’ sites. Our users may also choose to place ads on their site through our ads program. Additionally, we also show ads from our ads program on some of our own websites (e.g. longreads.com).

We operate our ads program in partnership with third party vendors. As part of the operation of our ads program, we use cookies to collect certain information. Advertising cookies enable us and our partners to serve ads and to personalize those ads based on information like visits to our sites and other sites on the Internet.

Below is a representative list of our advertising program partners, along with information on the cookies that that each partner sets. The partners we work with change from time to time, and this is not an exhaustive list. Your choices to control cookies related to our ads program are described below.
