WebReaper is Freeware for non-commercial use. You may use the fully functional application for as long as you like, without restriction, and with support from myself.
However, if you like WebReaper, find it useful, or use it in a commercial environment, please register your copy, giving you peace-of-mind, safe in the knowledge that you've contributed to the development of the application.
Registration costs just $40, and can be done from within the application (within the About dialog box, under the Help menu), using a secure credit-card payment system.
