Do I get the customer information (e.g., email or state) from sales made through my direct-to-reader sales page?

We’re only allowed to share the customer’s information if they provide consent during their sales transaction. If the customer chooses not to share that information, we cannot disclose it. There’s no way to “force” the customer to give us that information if they don’t want to (i.e. we cannot deny them the book sale). If you want to connect with your readers, consider setting up a Facebook or Goodreads account.
