We like to know who licenses our fonts, and to see what countries are interested in our fonts :)
And your registration details are used for the electronic receipts - for your accounts.
You could of course register with bogus details, but then your receipt would be all wrong.
You'll also have easy access to your previous orders from your account.
And we also plan some other features for registered customers...
No worries - we will not use your details for anything, and we will NEVER give them away to anyone else.
