Licensing models

Buy only	The end user buys a license, activates the protected program automatically via the Internet, or does so manually via the web site, e-mail, or phone/fax.
Try&Buy (Trial)	The end user can work with the protected program during certain period of time defined in the license without buying it. When the trial mode is over the program can be worked with only after it is activated with a valid license.
Try&Die	The end user can work with the protected program during certain period of time. When the trial period elapses the protected program will no longer function and cannot be reactivated by a valid license.
Demo	This mode is applicable when protecting non-commercial programs – beta versions, pre-releases, etc. As is usual, the life scope of a demo program is determined by its license.
Rent	The end user buys a rent license for a certain period of time. When the license invalidates it is required to buy a new one in order for the protected program to continue functioning.
Subscription	The end user buys a subscription and is granted access to the protected program during a certain period of time. When the license time elapses the end user is required to prolong it, otherwise the protected program will not function.
