Cell Phone Technicians Copying Personal Files

Is it ok for cell phone technicians to copy pictures or personal data from your phone, when they are fixing it?

I find it a little funny, but then I also find it very violating into someones privacy. Think about it, you have to give them your password so they can work on your phone, they have access to EVERYTHING.

Is it our fault thay we have those types of pictures on our phone? Or should they mind there own business? We give them access to everything, even if it is on the cloud or in a password protected file, they still can gain access to it. I have heard that they keep a file at work that they save all of these photos or data for themselves. Is this against the law, it should be? It would be my word against theirs if I tried to press any charges, but I would feel very violated.  Would that be my fault that I left them on my phone knowing that they have access to them? Or should I just put my trust in them? They are fixing my phone.

Let me know what your thoughts are.
