Cookies on the Meta Products
About cookies
Cookies are small pieces of text used to store information on web browsers. They’re used to store and receive identifiers and other info on computers, phones, and other devices.
Example: Cookies let websites know if you’ve visited that site before, which can help with things like saving an item to your shopping cart or remembering your display settings.
Other technologies, including identifiers associated with your device, and other software, are used for similar purposes. We refer to all of these technologies as cookies.
Ways we use cookies
Cookies help us provide, protect and improve the Meta Products, such as by personalizing content, tailoring and measuring ads, providing a safer experience and analyzing use of our systems.
Note: The cookies that we use include session cookies, which are deleted when you close your browser, and persistent cookies, which stay on your browser until they expire or you delete them.
What we use cookies for
Authentication
Cookies allow us to:
  • Verify your account and determine when you’re logged in so we can make it easier for you to access the Meta Products and show you the appropriate experience and features.
  • This means that cookies help us:
    • Keep you logged in as you navigate between Facebook Pages.
    • Remember your browser so you do not have to keep logging into Facebook and so you can more easily log into Facebook through third-party apps and websites.
Security, site and product integrity
Cookies allow us to:
  • Help us keep your account, data and the Meta Products safe and secure. For example, cookies help us:
    • Identify and impose additional security measures when someone may be attempting to access a Facebook account without authorization (like when someone is rapidly guessing different passwords).
    • Store information that allows us to recover your account in the event that you forget your password or to require additional authentication if you tell us that your account has been hacked.
  • Combat activity that violates our policies or otherwise degrades our ability to provide the Meta Products. For example, cookies help us:
    • Fight spam and phishing attacks by enabling us to identify computers that are used to create large numbers of fake Facebook accounts.
    • Detect computers infected with malware and take steps to prevent them from causing further harm.
    • Prevent underage people from registering for Facebook accounts.
Advertising, recommendations, insights and measurement
Cookies allow us to:
  • Show ads and make recommendations for businesses and other organizations to people who may be interested in the products, services or causes they promote. These cookies allow us to:
    • Deliver ads to people who have previously visited a business’s website, purchased its products or used its apps and to recommend products and services based on that activity.
  • Measure the performance of ad campaigns for businesses that use the Meta Products. For example, we use cookies to:
    • Count the number of times that an ad is shown and to calculate the cost of those ads.
    • Measure how often people do things such as make a purchase following an ad impression.
  • Serve and measure ads across different browsers and devices used by the same person. This means that we can use cookies to:
    • Prevent you from seeing the same ad over and over again across the different devices that you use.
  • Provide insights about the people who use the Meta Products, as well as the people who interact with the ads, websites and apps of our advertisers and the businesses that use the Meta Products. For example, this means that we use cookies to:
    • Help businesses understand the kinds of people who like their Facebook Page or use their apps so they can provide more relevant content and develop features that are likely to be interesting to their customers.
Site features and services
Cookies allow us to:
  • Enable the functionality that helps us provide the Meta Products. For example, cookies help us store preferences, know when you’ve seen or interacted with Meta Products’ content and provide you with customised content and experiences. This means that cookies help us:
    • Make suggestions to you and others.
    • Customize content on third-party sites that integrate our social plugins.
    • Allow Page administrators to switch between posting from a personal Facebook profile and their Page.
    • Support your use of Messenger chat windows.
  • Help provide you with content relevant to your locale.
    • For example, we store information in a cookie that is placed on your browser or device so that you will see the site in your preferred language.
Performance
Cookies allow us to:
  • Provide you with the best experience possible. For example, cookies help us to:
    • Route traffic between servers and understand how quickly Meta Products load for different people.
    • Record the ratio and dimensions of your screen and windows and know whether you’ve enabled high-contrast mode, so that we can render our sites and apps correctly.
Analytics and research
Cookies allow us to:
  • Better understand how people use the Meta Products so that we can improve them. For example, cookies can:
    • Help us understand how people use the Facebook service.
    • Analyze our systems and which parts of the Meta Products people find most useful and engaging.
    • Identify features that could be improved.
Third-party websites and apps
Our business partners may also choose to share information with Meta from cookies set in their own websites' domains, whether or not you have a Facebook account or are logged in.
Cookies named _fbc or _fbp may be set on the domain of the business partner whose site you're visiting. Unlike cookies that are set on Meta's own domains, these cookies aren’t accessible by Meta when you're on a site other than the one on which they were set, including when you are on one of our domains. They serve the same purposes as cookies set in Meta's own domain, which are to personalize content (including ads), measure ads, produce analytics and provide a safer experience.
