I won’t give or sell your contact information to anyone. Ever. If you check the little box allowing me to contact you, I might send an occasional email to offer you something free, something on sale, or something new. Or I might not. In 2021, I think I sent 3 emails. If you want to make sure I never send you anything other than order confirmations, just uncheck the little box when you place your order.
Simple as that.
