Google Analytics mainly uses first-party cookies to report on visitor (aka. user) interactions on Google Analytics customers' websites. Users may disable cookies or delete any individual cookie.
Where a site or app uses Google Analytics for Apps or the Google Analytics for Firebase SDKs, Google Analytics collects an app-instance identifier - a randomly generated number that identifies a unique installation of an App. Whenever a user resets their Advertising Identifier (Advertising ID on Android, and ID for Advertisers on iOS), the app-instance identifier is also reset.
Google Analytics also collects Internet Protocol (IP) addresses to provide and protect the security of the service, and to give website owners a sense of which country, state, or city in the world their users come from (also known as "IP geolocation").
