Yes, this is what management commands are for. You start these usually with a cronjob.

I believe the most straightforward way to go about this is to hide the data to the clients. This is done by adding some expiration_date field to the model. Then you may have a custom manager that looks like:

class ValidObject(Manager):
    def filter_valid(self):
        return self.filter(expiration_date__gt=datetime.date.today())
