We take privacy of our users and their audience *very seriously*.
When a giveaway is run through Rafflecopter, only the giveaway admin have direct access to the entrants' name, email, IP, time of when they entered, and how they entered. When entrats sign into the widget, they can use either their FB account via FB connect, or use their name and email address combo. We provide you the email address of every one that entered so that you're able to contact the winners of your promotion.
It's basically this: we'll never ever take the data and sell it/use it in a malicious way. We'll never email those folks who enter your giveaways set up through the Rafflecopter application. We realize privacy is a concerning issue for admins & entrants alike.
