@fahlawfulls > You're concerned about privacy yet your registration here on the forums provides Pioneer with the same amount of information your registration with rekordbox does; your "name" and an email address. After you register rekordbox, there is no communication to Pioneer. Pull up a firewall and see for yourself.
The KUVO functionality allows you to have your tracks posted to the KUVO network ONLY when DJing at a club that has a KUVO gateway in place and ONLY when you haven't marked yourself as private and your tracks aren't private.
You don't _need _to register if you don't want to use the free software, but if you do, all it takes is your "name" and email address, and that's all Pioneer ever gets.
Now take off the tin foil hat and get back to mixing. ;)
