There is described a method of managing data objects in a portable device (20) which is operable to be periodically synchronized to a host device (10). The method comprises steps of: (a) establishing a database for storing a record of the data objects and associated numbers of times said data objects are rendered to users or consumed by users (80) of the devices (10, 20); (b) determining whether or not a given data object of said data objects is rendered or consumed more than a threshold number of times; and (c) deleting said given data object from at least one of said portable device (20) and said host device (10) when said given data object is found to have been rendered or consumed more than said threshold number of times. The method is relevant to devices provided with limited data storage capacity, for example personal data assistants (PDAs), palm-top computers, mobile telephones and such like.
