Brand new to this process, but discovered this project while looking for ways to get involved with citizen science and eagerly downloaded and started the process.

I mentioned to one of my professors, being the proud contributor to science that I am, that I downloaded this project and started volunteering my computer to help the cause.

His first response was "You are braver than I am." To which I asked, "And why is that?"

He said he would be afraid of personal information being compromised on his local computer.
I never gave it much of a thought being an eager volunteer until he mentioned it.

Is this a legitimate concern or paranoia?
