Are apps written in Adobe Air Safe?

Hi

I'm interested in buying a little app called YNAB to use for home expenditure tracking for tax etc.

I quite liked the simple interface of YNAB compared to the many other financial apps out there.

The issue is that it is not on the App store and when I asked why, the developer said Apple does not allow apps created using Adobe Air on their App store.

So the question is, does Adobe Air create a security risk or can it effect my Mac performance in a negative way, or is this just a policy from Apple that has more to do with competing software technologies?

Thanks for the post.

So Apps created in Adobe Air are not a security risk or anything like that, and will not play any havoc with the operating system?

(Please excuse these ignorant questions as I am new to Mac).
