entity that can't be saved or copied

[johnteng00]

Hi guys,

I have developed a plugin which will create entities in DB, I want to give users the free trial version. But I don't want user to use my software in the real project. Is it possible to create a temp entities that user can only see it but they can't not save or copy it? Does anyone have such sample codes that I can use?

thank you.
