Cookies help us provide, protect and improve the Meta 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 Meta Products, we use them for the following purposes:
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 7 days, for purposes including to deliver an optimal experience for your device’s screen.

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.
