Cookie Policy

Last Updated: 12 June, 2018 This Cookie Policy describes how Meta uses cookies and similar technologies to provide, improve, promote and protect our website and other related Meta services (the “Services”). To the extent we use any terms that are not defined herein, these terms shall have the meanings set out in our Terms of Use and Privacy Policy.

Meta uses cookies and other similar technologies


Cookies are small text files sent by your computer or device each time you visit our website. They are stored in your browser’s cache or mobile device and allow a website or a third party to recognize your browser. Other technologies, including data we store on your web browser or device, identifiers associated with your device, and other software, are used for similar purposes. In this policy, we refer to all of these technologies as “cookies.” Some of the cookies we use are associated with your Meta account (including information about you, such as the email address you gave us) and other cookies are not. We use three different types of cookies:

  • Session cookies are specific to a particular visit you make to Meta and hold certain information as you browse different pages so you don’t have to re-enter information every time you change pages. Session cookies expire and delete themselves automatically in a short period of time like after you leave Meta or when you close your web browser.
  • Persistent cookies remember certain information about your preferences for viewing Meta and allow us to recognise you each time you return. Persistent cookies are stored on your browser cache or mobile device until you choose to delete them.
  • Third party cookies are a type of persistent cookie and are placed by someone other than us. These cookies may gather browsing activity across multiple websites and across multiple sessions. They are stored until you delete them or expire based on the time period set in each third party cookie.

We partner with third-party analytics providers, Adobe and Google, which set cookies when you visit our websites. These cookies collect information, such as how often users visit our websites, what pages they visit, and what other sites they used prior to coming to our websites. We use this information to learn how our Services are being used so we can make them more useful for you. We also use tools from Google and Facebook to help us advertise Meta on other websites, and to determine the effectiveness of such ads. Please see how you can control or limit how we and our partners use cookies below, under “Your Choices.”


Pixels are small images on a web page or in an email. Pixels use unique identifiers to collect information about your browsing activity. Meta uses Facebook re-marketing pixels to collect data about your activities that do not directly identify you when you visit our websites. We use the information we collect to serve you with ads for the Services on Facebook.


Some of the technologies described herein are employed to make our Services function for their intended purposes, and are provided based on the Terms between you and us. These include the functions strictly necessary to provide the Services. By signing up for or choosing to use our Services after having been notified of our use of cookies and similar technologies, you consent to such use in accordance with this Cookie Policy:

  • Authentication and security. Cookies and similar technologies help us verify your account and device to maintain the security, safety, and integrity of our Services. For example, we use cookies to help keep you logged in when you come back to the Service.
  • Account and user preferences. We use some technologies to remember your account and preferences over time so that we can make it easier for you to access the Services and provide you with the experiences and features you desire. For example, we save the Feed you last used when you were on Meta so it’s pre-populated the next time you visit.
  • Performance and analytics. Cookies and similar technologies help us analyze how the Services are being accessed and used, and enable us to track the performance of the Services. This gives us the information we need to improve your experience on our Services.
  • Ads to encourage use of Meta. As mentioned above, in order to provide you with Meta ads and encourage use of Meta, we partner with third parties who may set cookies on your device or browser to gather information about your activities on the Services and other sites you visit. For example, if you visit Meta and also use a social media platform such as Facebook, you may see a Meta ad in your newsfeed.

Your choices

You have a number of options to control or limit how we and our partners use cookies and similar technologies.

  • Although most browsers and devices accept cookies by default, their settings usually allow you to clear or decline cookies. Note that if you disable cookies, however, some of the features of our Services may not function properly.
  • To learn more about how to opt out of ads about Meta on Facebook that are shown to you based on your use of Meta, you may use your Facebook settings. Facebook’s Data Policy can be found here.
  • To learn more about how Adobe uses information it collects from you through your use of Meta in connection with its analytics service, you may visit Adobe Privacy Center.
  • To learn more about how to opt out of Google’s use of cookies as part of its Analytics services, you may visit Google’s Ads Settings. You will be able to prevent your data from being used by Google Analytics by installing Google’s opt-out browser add-on from the Google Analytics Opt-out Page.
  • You may also learn about how to opt out of ads about Meta on Google by referring to “How Google Uses Data When You Use Our Partners’ Sites and Apps.” The AdWords service allows us to show you ads about us on Google through your use of Meta.
