A server is connected via a network to a plurality of information terminals in which predetermined application programs are executed. When the predetermined application programs are executed, the information terminals notify the server of member identifiers that identify the users. The server generates program identification numbers identifying the predetermined application programs stored in the plurality of information terminals, correlates the program identification numbers with the member identifiers, and manages each application program (program identification number manager). Then, the server verifies whether the program identification numbers transmitted from the information terminals at the time the predetermined application programs are started match program identification numbers managed in the server. If the program identification numbers do not match, the server (use request signal processor) transmits save data when the user previously terminated the application program, which save data is managed by a save data manager.
