befor I finish and submit my application using Sencha Touch 2.0 RC2 in to the Application Stores, I want to be sure that I am allowed to use it.
Question is: As a free developer I am developing an hobby application with Touch 2.0 RC2. What should I do to make this application legal? Should I write at any document that I used Sencha Touch?
I am living in Germany and here is the legality very very important. Please give me a hint.
