how to create sketch that cannot be saved?

Hi guys,

Could anyone help.

We develop the solidworks plugin. We want to give users the free trial version. The result of our product is a newly created sketch in solidworks. We want to create such a sketch that user can only see it but can't save it into a file or copy it to create another sketch. Is it possible in Solidworks?

thanks you
