You could download an earlier version from before they were bought, it's what I'm doing. Still better than every other launcher I've tried. I'm also preventing it from accessing the internet via GrapheneOS settings, but I don't think every OS can do that.

Yeah, I just installed the apk from an older release off apkmirror and installed Pro from the play store. I also disabled auto-update in the play store for both. You should look up if your OS can disable network connectivity on an app to app basis, the steps are different on each OS but it's usually buried somewhere in the settings. If your OS is unable to do so, I would use Netguard to prevent applications from using the internet.

Edit: Like someone already mentioned, the apk for each release is also available in the Nova launcher discord server.

Oh, thanks for letting me know. I'll downgrade again, I doubt there's much of a feature difference between those releases anyways.

FYI, you can download a version from before the acquisition. I'm running the 7.0.25 release and restricting network access on both the base app and the premium license. Not sure if it's foolproof, but hopefully I find a launcher that does app drawer tabs at least as well.

I'm still using Nova but I've downgraded to a version released before the acquisition and restricted network access. Still haven't found a launcher that does app drawer tabs as well as Nova has. That's pretty much the only feature holding me back from switching to another launcher.
