This maps your email to downloads and, once you buy, to your key and invoices. Pick where you want to start; the trial needs nothing from you but the address, and a paid licence is still settled by bank transfer - see pricing for why there is no card form.
What happens next
Confirm the address and the trial unlocks. A licence is then invoiced by mail with a bank-transfer line; the key comes back when it clears. A teaching seat skips the invoice once we see where you teach.
We keep your email and which licences it holds, nothing more. No card number reaches this site - there is no gateway on it, a choice explained on the pricing page.
