 In cloud-mode, Analytics-React-Native functions as a normal Segment library. In device-mode it wraps the Segment [Analytics-iOS](/docs/connections/sources/catalog/libraries/mobile/ios/) and [Analytics-Android](/docs/connections/sources/catalog/libraries/mobile/android/) libraries, and loads the appropriate mobile library depending on the user's platform. Because of this, Analytics-React-Native includes the two mobile libraries as dependencies.

This is known as sending your data using "Cloud-mode", and it helps reduce the size of your project.
 
 However, some destinations require that you include code in your project that can be run on the user's device so that these tools can function correctly. These destinations send data directly to the destination's API endpoints, as well as sending a copy to the Segment servers for archiving. This is known as sending data in "device-mode". Other destinations offer a device-mode SDK, but still work (with reduced features) in cloud-mode.
