Embodiments of the invention relate to synchronizing service data between a data store and a device using the service data. A synchronization method and device are described that adaptively adjust synchronization parameters, such as the synchronization interval and quantity of synchronized data, on a per-end-user basis in response to usage characteristics of the service data. In particular, heavy use of service data results in shorter synchronization intervals and/or increased synchronization data quantities, which provides closer to "direct access" performance. Light users of service, on the other hand, are assigned lower cost synchronization parameters, such as longer synchronization intervals and/or decreased synchronization data quantities
