Since the church is a private organization, and you were a member, there probably aren't any legal ramifications. They can keep whatever records of their members they made as long as they want to. There isn't, as far as I know, any legal obligation of any kind to destroy them, to keep them confidential, or to make them available to anyone. They own the records, even if they're about you.
And no, they're not destroyed. Even if you officially resign.
They keep everything.
