No. By default all interaction on Conferences i/o is completely anonymous. Audience members do not need to enter any personal information in order to use the app, and we have no way of tracing responses back to individuals.

However, moderators do have the option of asking attendees to enter some sort of ID information (name, email, etc.) which allows moderators to track attendee data. This is an optional setting though, and not required in order to use Conferences i/o.
