2. Ownership

The Software, including all code, design, graphics, and documentation, is the intellectual property of Gain Publications and is protected by copyright law. Your purchase grants a license to use the Software — it does not transfer ownership of the Software itself.

7. AI-Generated Content Disclosure

Audio produced by StoryVox is generated by artificial intelligence. Some distribution platforms (such as ACX/Audible) may require disclosure that content was AI-generated. It is your responsibility to comply with the terms and policies of any platform where you distribute your audiobooks.
