Currently the only paid version without ads will be the steam one.
But as I said in another comment, I'm looking for ad providers that are privacy friendly. I keep my hopes up that such provider much exist. Or that I can maybe skip providers and display banners to publishers directly, where tracking only occurs if the ad is clicked.
And I'm also considering released paid ad-free iOS and android versions, it just won't happen right away.
And at the moment, there is no tracking at all on the website (except if you create an account, there are just cookies to save scores)
