Pretty safe. I have seen contracts on several different sites. This one by far is the most fair, at least in my opinion. I have 2 stories with them and have been with them over a year (before app launch) and seen how they handle growth. I keep all rights (all the other authors will tell you the same) and I have a lot of say with the cover, the lore cards, and how the story progresses. I have also seen some authors leave the platform due to one having a kick starter become super successful and wanted to do that and another got picked up by a traditional publisher. As far as I can tell it was a clean break Mythrill kept the artwork they made and the author kept the story. There doesn't seem to be any bad blood. Personally, I'm sticking with them. I'm really happy with the marketing materials, the editing, and the artwork. They have paid me on time when I've hit withdrawal point and the quarter had finished. Super easy to report bugs and ask for an edit when you've missed something and it went live. They are working on an author portal, so right now it's mostly using google docs.
