If you never create an Anki web account, I don’t think your data ever hits their servers at all. The app itself is a downloadable. Unfortunately then you won’t be able to sync across devices. If you google around, I’m sure there is a solution to this problem somewhere. Now that I think of it, I suppose you could export your decks then import them manually on a separate desktop /laptop. Not sure if that would work on mobile.
