Do you store my payment information?

No. Your payment is handled by an established, secure payment processor. Your card details go directly to them — we never see, handle, or store your card number. What comes back to us is only a confirmation that the payment succeeded, which we use to issue your license key.

So there's no card data sitting in a BookPublish account to worry about. The only thing we keep is your license key and (if you made an account) your email address. See Privacy & file safety.
