Our official stance is that if you’re going to use it for a bunch of people then it’s probably best to have each person buy one. But we don’t do DRM (Digital rights management) and there’s nothing preventing you from using our stuff multiple times across multiple computers.
So, if you're going to share the trainer, we’d ask that you try them out, and if you really like them and get good results from them, then please tell your friends.
If you get three friends to buy our stuff then you’re karmically in the clear.
With regards to the Official App, each person will need their own account. (NO SHARING) There’s honestly no way to share the app with anyone else in a useful way.
