Checkout and payment happen on a secure checkout page. This site does not collect or store your card number.
If you accept cookies, we use them to measure the shop and to remember how you found us. If you decline, those tags stay off.
The email signup only keeps your address after a mailing list is connected. Until then, the form tells you it wasn't saved.
The contact form opens your email app, or forwards the note, only when that inbox is connected.
