When you order a license for the uCalc 4.0 Graphing Calculator, you receive a registration code that prevents registration reminders such as the opening message box from appearing.
Individual User
Choose this option if you are an individual who will be using uCalc on your own personal computer(s), and you are not covered by the Unlimited Member License (explained further down). If you are a student, you may want to check with your school to see if they do not already have an Unlimited Member License for uCalc, in which case you are entitled to a free license for home use. If they do not already have it, lead them to this web page for details on how to obtain it.
Site License for multiple computers
A special discount is offered to schools, libraries, small business, and non-profit organizations, which allows them to purchase a site license for as little as $2 per computer. When you click on the Buy Now drop-down menu, you will be able to select a price that matches the number of computers you want to purchase a license for. Schools may find it convenient to also purchase an Unlimited Member License, which is explained below.
Unlimited Member License
If you purchase an Unlimited Member License -- in addition to a Site License that covers the computers of your institution that are accessible to all members (such as students, teachers, etc) -- then all members have a free license to use the uCalc Graphing Calculator on their own home computers. This is a cost effective way of letting students freely and legally use the same uCalc software from school on their home computers.
NOTE: The Unlimited Member License should not be purchased alone. This is an option you can purchase only if you have also purchased a Site License for multiple computers.
