To be clear, I know that "pay once, lifetime updates" isn't a good fit for some things. But the website isn't particularly clear on this - there's a subscription model, but then a Pay Once model that then says "one year of app updates". Of App Updates only? Of model updates? Of both? Looking at an info block below, it seems like if you buy once, you get "new features and improvements" to the app for one year. But are you model locked?
