It has been my experience if one person has a question others have the same question. So, here is the answer: we do absolutely nothing with the info other than to use it to mail prizes or contact the winner by email if we have a question. At the conclusion of the contest, the information, saved on a Google Doc, is deleted. Participants give us their name (some just give initials or a first name), mailing address, email and contest choice.
Since the information passes through our hands quickly and is gone, it never occurred to me to explain what we do–or not do–with it. Again, the information we collect is used for one raffle and deleted completely.
I am sincerely sorry if I have offended anyone or caused anyone undue worry wondering what we did with the information they have supplied.
Thank you for your feedback.
