The message form takes a name, an email and text. Those three things are stored so that somebody can answer you. Nothing is collected before you press send.
The shop is not open, so there are no orders, no addresses for delivery and no payment details. When selling begins, this page will be rewritten before the first order is accepted.
A message stays while the conversation is alive and for a year afterwards, then goes. You can shorten that to zero at any time by asking.
One person, in one mailbox. No bulk mailer, no statistics service, no advertising network. The page loads without a single external request.
Ask for a copy, a correction or a deletion using the same form. All three requests are handled the same day when possible.
