License

Tune is free for personal, non-profit use. The rules are:
1: I grant you a license. This means I have copyright, but you can download Tune and use it for free.
2: If you want to use Tune for education of others, you must first contact me for a licensing agreement.
3: You may not redistribute Tune in any way. I hope you will recommend Tune to others, but please do so by linking to this site.
4: Tune expires at New Year. This gives me the possibility to decide its future, and if nothing else forces users to check for an update at that time.

I ACCEPT

Enjoy your training,
Flemming Nyboe
