Disposable mini-applications are executable software items whose activation, deactivation and deletion in a mobile terminal are defined by trigger parameters and rules. Trigger parameters may include, but are not intended to be limited to, location, time, stored user data and the like. Rules are one or more trigger parameters needed to effect one of the foregoing actions. In one embodiment, a housekeeping means monitors for data that corresponds to the parameters and satisfies the rules, and performs a variety of housekeeping functions relating to the disposable mini-applications. The deletion of the disposable mini-application clears memory space associated with storing and executing the disposable mini-application, and thus, makes that space available for other purposes.
