Rikki - hi there. Glad you like the site (or the idea of the site at
least)
We've honestly not gotten any complaints or worries from people about
privacy. However, if you are worried - and I would imagine that there
are people who are - we do offer the option to make your routes
private, all you need to do is create an account (yes, its free) and
the "make route private" option will show up in the save dialog.
Marking a route as private only makes it available to you, when logged
in.
Thanks,
Jeff
