About Hobby License:
A Hobby license is a full-featured license: only the price is lower than for a commercial license. Even much lower: the hobby discount on DP Full is 75%. A few restrictions do apply though:
A hobby license may be bought only by a private person, not by a company (also not by an employee or owner acting as a private person but in fact buying for the company).
A hobby license may not be used for any commercial application.
For hobby licenses the free support by telephone and email does not apply: use the Forum instead.
A hobby license may not be sold or transferred to another user.
