License terms

All licenses include access to any/all translations for Windows or Mac OS X. (The iOS version must be purchased via the App Store.)
Single-user registration entitles you to install the program on multiple computers in your household, or your home and work computers, so long as you only actively use it on one computer at a time.
Site licenses allow for installation on school-owned computers based on the number of concurrent users of the program (i.e. the number of students expected to be using the software at any given time, not the number of machines on the network).
Bulk licenses are available to schools to distribute copies for use by students on their own computers. These licenses become property of the student upon distribution and so need to be renewed annually to cover newly-enrolled students. Please e-mail me for additional information.

Ordering

Online by electronic payment:

At the moment I am without a registration site--Digital River has acquired and consolidated every e-commerce provider I have ever worked with, and announced recently with very little notice that I am no longer welcome as a customer because I don't do enough volume.

Please email me if you'd like to send a payment via PayPal.
You can deploy the version of the program you downloaded as soon as your receive your order confirmation. For site license orders, I'm happy to provide a copy of the current version on CD and/or a printed license certificate; just send me an email requesting physical delivery.
For student bulk licenses or site licenses with an uncommon number of users, please email me for a quote.
