Limit iPad Content Access

Hello. Just purchased Storyline today and am excited about the possibilities.

I created a 2 screen sample, published it, and uploaded it to my website. It's working fine, viewable through the articulate ipad app.

My goal is to sell the ipad version of this content. I want to only allow people to view the content online through an ipad, not through a pc. 

If I give them the link to the ioslaunch.html file, rather than story.html will that work? When I access that page from a pc browser it displays the initial screen with a launch button, but doesn't go anywhere when clicked, which is fine. I didn't know if that would cause any other problems though.

Then if you want to limit access to that page, just password protect the file or folder?
