Good afternoon, recently I had a profound personal dispute with someone and the conversation abruptly ended with many things left unsaid. I decided to write a long text do this person, but I don't want him capable of saving the text for future reference. I want to send him the text but restrict him from the possibility of copying it. I'm looking for some sort of solution that renders my text unable to be copied and also that I am able to delete it after I know the person has read it. Is there anything such as this?
