Understand that this is not our software, just an easy way to publish the BruCON schedule and to register workshop attendance.
by registering you do agree on:
if you do not want your real name to be exposed, use a fake name or alias.
There is a setting in your sched profile that enables you to hide your participation in the sessions:
Hide my profile & schedule so nobody will be able to meet me:"
(click "Change your username, password and privacy settings." at the bottom when editing your profile)
Also, we have been made aware that there is a vulnerability in the Sched mobile App that sends credentials in clear text.
We have raised this to sched.org who are working on a fix.
Meanwhile: do not (re)use any of your existing credentials and preferably use the web client that uses SSL
