Does the Kiwi Linux Live CD write to the hard drive?

[Weestro]

Hello,

I have recently downloaded and tried the latest Kiwi Linux (version
10.08) using the live CD. I wonder if the live CD will write anything
to the hard drive. I want a live CD that can be used as a totally
secure way to browse the Internet. Would you be so kind as to reply if
you are sure you know?

I downloaded from from http://kiwilinux.org/kiwi/en/news.html, which
is the correct site I understand.

Thank you for reading my post.
