How a download works here

You enter an email on the product page. That email is how we find the purchase later. Checkout runs on the payment page, not on this site, so card details stay off the shop.

When the charge is confirmed, the same page turns into your download. The link is private to that purchase. You can use it eight times, which covers a new laptop and a bad connection without leaving the file public.

The PDF is not on the product page before you pay. The description, the contents, and the price are. If you close the tab, open Your files and enter the same email.

A refund, when the refund policy allows it, turns the link off.
