We are very careful about data security and privacy. Our platform has passed some very tough security audits by our clients. The only fields that are mandatory for all promos are: Email address and Date of Birth. The optional fields, as chosen by the contest creator, are First Name, Last Name, Phone Number, Mailing address and Agree to rules. We also allow you to ask your participants to opt-in to an email newsletter if you want.
We don't collect other information from the contests. We use Facebook Connect to verify certain data- like Date of Birth (since age is very important for eligibility for some contest creators.)
we never retarget one contest's participants with another client's contest.
