A web application operating method in a terminal connected with a server for distributing content that constitutes a predetermined service and that contains a statement indicative of arbitrary processing to be executed, the method comprising:

• storing in a storage section content distributed from said server and a data access power for deleting a service that differs from a service to which said content belongs, in association with each other;
• when the content that is stored in said storage section requests the deletion of a differing service that is indicated by the statement contained in said content, determining whether or not said content and the data access power are stored in said storage section in association with each other;
• and
• when it is determined that said content that requested the deletion of the differing service and the data access power are stored in said storage section in association with each other, deleting content that belongs to the differing service.

• storing in a storage section content distributed from said server and a data access power for deleting a service that differs from a service to which said content belongs, in association with each other;
• determining, when the content that is stored in said storage section requests the deletion of a differing service that is indicated by the statement contained in said content, whether or not said content and the data access power are stored in said storage section in association with each other;
• and
• deleting, when it is determined that said content that requested the deletion of the differing service and the data access power are stored in said storage section in association with each other, content that belongs to the differing service.
