1. A communication device associated with a hearing-impaired user, the communication device comprising: communication elements configured to receive audio signals from a far end communication device, and to receive text captions corresponding to the audio signals from a captioning communication service for display by the communication device during a call; a memory device storing a local database of data records for the communication device, each data record having at least one flag associated therewith indicating whether the data record has been locally modified by the hearing-impaired user responsive to a user input to the communication device; and a processor operably coupled with the communication elements and the memory device, the processor configured to synchronize unclean data records from the local database with a remote database of a remote server associated with the captioning communication service responsive to querying flags in the local database that indicate data records that are unclean, wherein the at least one flag includes an add flag, an update flag, and a delete flag that are set locally as either clean or unclean responsive to the user input to the communication device prior to synchronization with the remote server, wherein the add flag is indicative of a new data record being created since the last time synchronization occurred with the remote database, the update flag is indicative of an existing data record being changed since the last time synchronization occurred with the remote database, and a delete flag is indicative of an existing data record being removed since the last time synchronization occurred with the remote database.
