Tilted Windmill Press is a private label press for certain works by me (Michael W Lucas, etc). My family are the sole owners of Tilted Windmill Press, which means I can and do treat your data as I would hope mine would be treated.
The guiding principle of all my business decisions is: given a choice between “abuse personal information for a nickel” and “write more and better books to persuade you to willingly hand over more of your cash more often,” choose the latter.
Personal information (name, addresses, etc) is used only to deliver service.
Mailing list sign-ups at check-out default to opt-out.
I can access select personal information via Paypal and Stripe, same as any other online vendor. I use this information only to take payments and resolve issues. The only financial data I want is from my payment processors saying that “they paid you, hand over the loot.”
If you choose to have the site save your credit card for future purchases, or if you join the Patronizer program, the site does retain a payment token as well as the type of card, the last four digits, and the expiration date. Folks far smarter than I have determined that this provides adequate confidentiality.
I cannot validate physical addresses. My readers are highly likely to use network connections that obfuscate physical addresses. (This is part of why I don’t handle EU VAT.) If your physical address in your account is bogus, watch me not care. If you buy something that includes physical gifts, however (such as Patronage or a sponsorship), I will ship it to the mailing address in your account. Consider yourself warned.
Thank you for your support.
