Hi @Anonymous User
Once you buy the stick with a one off payment the stick is yours.
The stick may come bundled with some short term passes, but to continue watching NowTV you need to subscribe to the various passes or apply NowTV Gift cards.
You can dip in and out of the NowTV passes when you like.
Even if you don't want to use the NowTV service on the stick on setup of the stick when you create an account you have to give your bank card details.
The stick also comes with third party Apps such has BBC iPlayer, ITV Hub etc which you don't have to subscribe to NowTV to use these Apps.
Maybe have a read of these Help articles.
