A cookie is a small text file that is stored in your web browser that allows Expo or a third party to recognize you using a unique identifier.
Who sets them: First-party cookies are set by Expo. Third-party cookies are set by companies other than Expo, such as analytics providers and advertisers.
What they do: “Essential” cookies enable services we offer. “Non-essential” cookies help us understand how our services are being used (i.e., analytics) and deliver advertisements. Some cookies may track you across multiple websites you visit (including ones not operated by us) to help deliver advertisements that may be relevant to you.
How long they last: Cookies may be either “session” or “persistent.” A session cookie expires (i.e., is deleted) when you close your browser. A persistent cookie remains until it expires or you delete the cookies via your browser settings. Expiration dates are set in the cookies themselves and may vary in length, depending on the purpose of the cookie.
Cookies Found on Expo Services
We use all types of cookies in our web-based services.
Expo websites: When you visit an Expo website, Expo and third parties will set cookies in your browser. Expo sets essential cookies to enable certain features and remember your preferences. For example, cookies keep you logged in, allow you to purchase items, and maintain your language and volume settings. Third parties set cookies for both essential and non-essential purposes [including analytics (e.g., Google Analytics) and advertising (e.g., Google DoubleClick for Publishers)].

We use technologies that resemble cookies to help track user activities and preferences. For example, we may use web beacons (tiny graphics with a unique identifier embedded on web pages or emails) to track your activities and communicate with cookies. You cannot opt out of web beacons used on webpages, but you can limit their use by opting out of the cookies they interact with. You can opt out of web beacons used in emails by setting your email client to render emails in text mode only.
