I signed a confidentiality agreement with a company that was for an unpaid "job". I quit with them and now had some innovative ideas I had to share with them on past projects I couldn't do before.
Since I don't have the company e-mail, I can only e-mail the person who works there using insecure communication. I want to share my ideas but am reluctant to use any viable method of communication like e-mail, phone because I'm afraid I'll somehow violate the CDA even post termination of employment because I'm leaking "good" ideas on the web.
I'm also highly suspicious of their honor and finances and doubt they'll pay me for my efforts to bring new ideas to them-which doesn't mean that I'm doing this for money but I seriously like some money. What should I do?
