About cookies on this site

The wikimediafoundation.org site uses cookies and functional flags to deliver a consistent experience. These technologies may store or retrieve information on your browser related to your preferences or your device. This information is not typically used to identify you directly, it is there to give you a more personalized experience. They fall into three categories, based on their purpose:

  1. Functional cookies: Functional cookies are required for the website to work and cannot be switched off. Some are part of the site’s core infrastructure and are set automatically, while others respond to actions you take, such as setting your privacy preferences. These include cookies set by WordPress and Automattic, which run the site itself, and by Complianz, which records your cookie choices so we can apply them. They do not store personally identifiable information. You can set your browser to block these cookies, but some parts of the site may not work as a result.
  2. Preferences cookies: Preferences cookies remember your choices to make your experience more consistent across visits. This includes things like whether you have already submitted a feedback survey or previously dismissed a notice. They may also be set when third-party features are embedded on our pages, such as video players. This includes YouTube. We do not use these cookies to track your activity across other websites, though third-party features may set their own cookies when you interact with them. If you choose to disable them, some features and personalization options may not work as intended.
  3. Marketing cookies: Some marketing cookies are set when third-party advertising partners’ services are used on our site. They may be used to track your activity across websites and build a profile of your interests. They may collect your IP address, browser and device information, and the actions you take on our site. These services include Meta, Google, LinkedIn, and TikTok. We do not control how third parties use the data they collect beyond our site. If you do not allow these cookies, the content and campaigns you see elsewhere may be less relevant to you.

Cookies list

Below you can see every service that places cookies on this site, along with the category each one falls under. Expand a service to see its individual cookies. Your choice applies to wikimediafoundation.org only, and you can change it at any time by updating the consent center or adjusting the toggles on this page, which saves your preferences automatically.
