Cookies and other storage technologiesCookies 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".
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.
For example: Cookies help us route traffic between servers and understand how quickly Meta 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 seven days, for purposes including to deliver an optimal experience for your device's screen.

Third-party websites and appsOur 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. Specifically, 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 personalise content (including ads), measure ads, produce analytics and provide a safer experience, as set out in this Cookies Policy.
