Customer release?

I was talking with someone at work and she was talking to me about some computer problems she was having at home. She said that she wanted to call me or someone else I used to work with about coming over and fixing it. Her husband said no since they had their finance information on there and he didn't want anybody they knew to be able to have access to it.

I guess I can see his point so that brings up a question. Do you have some kind of release or confidentially statement you sign with your customers?

ps btw, a local big name computer shop only wiped the drive clean and started over. They lost their information.
