Do I need licenses for each user to use the cannyboard?

No, the cannyboard does not require any accounts, registration or licenses to use the Windows interface. Simply switch on the device and all the functions of the Windows interface are available without restriction, just like on a tablet PC.

Only in the event that you want to take over and save a work session in the integrated cannyboard app, personalized, you need a free cannyboard account, which they can create at cannyboard.app with a few clicks.
