Buying N-Track on Android and PC?

So I’m considering to buy N-Tracks because it’'s a great programm that suits my requirements. But the question is if I buy N-Track on the Android app throughout a Abo. Is it possible to use this “bought” Version on my PC when I use the same Account ? Or do I have to buy it separately?

If you need n-Track on both desktop and Android you would need to purchase it on both platforms, as the desktop (Windows and Mac) and Android versions of n-Track are separate purchases.
