Cookies & other storage technologies
Cookies are small pieces of text used to store information on web browsers. Cookies are used to store and receive identifiers and other information on computers, phones and other devices. Other technologies, including data that 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”.

We use cookies if you have a Facebook account, use the Facebook Products, including our website and apps, or visit other websites and apps that use the Facebook Products (including the Like button or other Facebook Technologies). Cookies enable Facebook to offer the Facebook Products to you and to understand the information that we receive about you, including information about your use of other websites and apps, whether or not you are registered or logged in.

This policy explains how we use cookies and the choices you have. Except as otherwise stated in this policy, the Data Policy will apply to our processing of the data that we collect via cookies.
Why do we use cookies?
Cookies help us provide, protect and improve the Facebook Products, such as by personalising content, tailoring and measuring ads, and providing a safer experience. The cookies that we use include session cookies, which are deleted when you close your browser, and persistent cookies, which stay in your browser until they expire or you delete them. While the cookies that we use may change from time to time as we improve and update the Facebook Products, we use them for the following purposes:
Authentication
We use cookies to verify your account and determine when you’re logged in so that we can make it easier for you to access the Facebook Products and show you the appropriate experience and features.
For example: We use cookies to keep you logged in as you navigate between Facebook Pages. Cookies also help us remember your browser so you don't have to keep logging in to Facebook and so you can more easily log in to Facebook via third-party apps and websites. For example, we use the "c_user" and "xs" cookies, including for this purpose, which have a lifespan of 365 days.
Security, site and product integrity
We use cookies to help us keep your account, data and the Facebook Products safe and secure.
For example: Cookies can help us identify and impose additional security measures when someone may be attempting to access a Facebook account without authorisation, for instance, by rapidly guessing different passwords. We also use cookies to 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. This includes, for example, our "sb" and "dbln" cookies, which enable us to identify your browser securely.
We also use cookies to combat activity that violates our policies or otherwise degrades our ability to provide the Facebook 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. We also use cookies to detect computers infected with malware and to take steps to prevent them from causing further harm. Our "csrf" cookie, for example, helps us prevent cross-site request forgery attacks. Cookies also help us prevent underage people from registering for Facebook accounts.
Advertising, recommendations, insights and measurement
We use cookies to help us show ads and to make recommendations for businesses and other organisations to people who may be interested in the products, services or causes they promote.
For example: Cookies allow us to help 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. Cookies also allow us to limit the number of times that you see an ad so you don’t see the same ad over and over again. For example, the "fr" cookie is used to deliver, measure and improve the relevancy of ads, with a lifespan of 90 days.
We also use cookies to help measure the performance of ad campaigns for businesses that use the Facebook 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. We also use cookies to measure how often people do things, such as make a purchase following an ad impression. For example, the "_fbp" cookie identifies browsers for the purposes of providing advertising and site analytics services and has a lifespan of 90 days.
Cookies help us serve and measure ads across different browsers and devices used by the same person.
For example: We can use cookies to prevent you from seeing the same ad over and over again across the different devices that you use.
Cookies also allow us to provide insights about the people who use the Facebook Products, as well as the people who interact with the ads, websites and apps of our advertisers and the businesses that use the Facebook Products.
For example: We use cookies to help businesses understand the kinds of people who like their Facebook Page or use their apps so that they can provide more relevant content and develop features that are likely to be interesting to their customers.
We also use cookies, such as our "oo" cookie, which has a lifespan of five years, to help you opt out of seeing ads from Facebook based on your activity on third-party websites. Learn more about the information we receive, how we decide which ads to show you on and off the Facebook Products and the controls that are available to you.
Site features and services
We use cookies to enable the functionality that helps us provide the Facebook Products.
For example: Cookies help us store preferences, know when you’ve seen or interacted with Facebook Products’ content and provide you with customised content and experiences. For instance, cookies allow us to make suggestions to you and others, and to customise content on third-party sites that integrate our social plugins. If you are a Page administrator, cookies allow you to switch between posting from your personal Facebook account and the Page. We use cookies such as the session-based "presence" cookie to support your use of Messenger chat windows.
We also use cookies to 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
We use cookies to provide you with the best experience possible.
For example: Cookies help us route traffic between servers and understand how quickly Facebook Products load for different people. Cookies also help us 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. For example, we set the "dpr" and "wd" cookies, each with a lifespan of 7 days, for purposes including to deliver an optimal experience for your device’s screen.
Analytics and research
We use cookies to better understand how people use the Facebook Products so that we can improve them.
For example: Cookies can help us understand how people use the Facebook service, analyse which parts of the Facebook Products people find most useful and engaging, and identify features that could be improved.
Third-party websites and apps
Our business partners may also choose to share information with Facebook from cookies set in their own websites' domains, whether or not you have a Facebook account or are logged in. Specifically, cookies named _fbc or _fbp may be set on the domain of the Facebook business partner whose site you're visiting. Unlike cookies that are set on Facebook's own domains, these cookies aren’t accessible by Facebook 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 Facebook's own domain, which are to personalise content (including ads), measure ads, produce analytics and provide a safer experience, as set out in this Cookies Policy.
Where do we use cookies?
We may place cookies on your computer or device and receive information stored in cookies when you use or visit:

  • Products provided by other members of the Facebook Companies; and
  • Websites and apps provided by other companies that use the Facebook Products, including companies that incorporate the Facebook Technologies into their websites and apps. Facebook uses cookies and receives information when you visit those sites and apps, including device information and information about your activity, without any further action from you. This occurs whether or not you have a Facebook account or are logged in.
Do other Companies use cookies in connection with the Facebook Products?
Yes, other companies use cookies on the Facebook Products to provide advertising, measurement, marketing and analytics services to us, and to provide certain features and improve our services for you.

For example, other companies’ cookies help tailor ads off of Facebook, measure their performance and effectiveness and support marketing and analytics. Certain features on the Facebook Products use cookies from other companies to function, for example, certain maps, payment and security features. Learn more about the companies that use cookies on the Facebook Products.

Third party companies also use cookies on their own sites and apps in connection with the Facebook Products. To understand how other companies use cookies, please review their policies.
How can you control your Information?
We use cookies to help personalise and improve content and services, provide a safer experience and to show you useful and relevant ads on and off Facebook. You can control how we use data to show you ads and more by using the tools described below.
If you have a Facebook account:
  • You can use your ad preferences to learn why you’re seeing a particular ad and control how we use information that we collect to show you ads.
  • To show you better ads, we use data that advertisers and other partners provide us about your activity off Facebook Company Products, including websites and apps. You can control whether we use this data to show you ads in your ad settings.
  • The Facebook Audience Network is a way for advertisers to show you ads in apps and websites off the Facebook Company Products. One of the ways that Audience Network shows relevant ads is by using your ad preferences to determine which ads you may be interested in seeing. You can control this in your ad settings.
  • You can review your Off-Facebook activity, which is a summary of activity that businesses and organisations share with us about your interactions with them, such as visiting their apps or websites. They use our business tools, such as Facebook pixel, to share this information with us. This helps us do things like give you a more personalised experience on Facebook. Learn more about off-Facebook activity, how we use it and how you can manage it.
