As the “Primary Author” of the book, the only special access you have on the Leanpub side of things, is to decide who the co-authors are, and what the royalty split is.

However, regarding authority, the answer is that as the “Primary Author” you essentially have all the authority over the book on Leanpub, as set out in various places in our Terms of Service: https://leanpub.com/terms.

In particular, please see “2.5 Types of Leanpub Users” , where you’ll find a section on the “Primary Author”.

You may also want to search the Terms of Service for other places where we mention the “Primary Author”.
