We collect Names, Emails, Country, and Level of study for sending out emails to the participants containing relevant information related to the hackathon. Currently, each hackathon registrant receives two pre-event emails detailing MLH’s offerings for hackers at the event they have registered for. Phone numbers are collected for emergency or incident response purposes during the hackathon. School information is needed for the season scoring, our initiative where every school gets points for every hacker that participates in or wins prizes at MLH Member Events.
