I have free version on iPhone. Can I purchase pro version on Internet at $19.99 and transfer my data to it?
I'm not sure what you mean here when you talk about the free version of mSecure. Are you talking about the older version of the app, mSecure 4, or are you simply wanting to purchase a Pro license for mSecure 5 which you have been using a free account? If you are talking about mSecure 4, did you run into a message telling you we need to update the app after updating iOS on your phone?
