Foliaro is shareware.
You can evaluate for free for 30 days, during which you can create/save
up to 50 nodes+images per file. After the
evaluation period finished, you cannot create new files nor can save nodes.
If you wish to use the software further on, purchase the license key.
The license is issued to an individual person for his/her exclusive use in his/her PCs
(you may install the software on multiple PCs in your office and home).
The license is valid even if the software is updated.
In case multiple users use Foliaro installed on a PC,
each user must obtain his/her license.
One license key should be registered, since Foliaro can not register each user's license key on a PC,
