You never write a document and safe it?
I don't know; if someone gets access to my pc, he's in my apartment and can
see what books I read and can check out my personal scripts on my desk.
And honestly, that's ok. I want to be somehow "existent" in this world and
for me, the risk of someone having access to my pc from my apartment is a
price I'm willing to pay.
I don't think real danger comes from "this direction".
But how do you manage this? Do you keep your room also free of personal data?
Or is your computer a notebook and your traveling a lot?
When I go traveling with my notebook (it not very frequently) I remove the
harddisk and use a trisquel live cd.
So I can be sure nothing gets stored and a thief don't has any of my data.
