Planning my App

ofcourse you'd have it on a server, you shouldn't store other user's info on other user's phones
the phone may only store the player's info [phone owner]

 

You need to have a server with a database that will store all the profiles and then each phone will access the profile by queries to that database.

I have something like this already set up. I store the user information on the server and dish it out in JSON objects to users.

I also have a similar setup with the user's profiles stored on a central web server. Anything else is impractical.
