Advertising identifiers are unique, non-permanent, identifiers associated with your Roku device. When you use your Roku device, Roku, its channel providers and their respective service providers may use advertising identifiers to serve ads personalized to your interests and to measure ads. When you reset advertising identifiers, the identifiers used prior to reset will no longer be used to display personalized ads on your Roku device. New identifiers will be assigned for that purpose.
