Olauncher is highly rated and collects/shares 0 data (at least according to the data safety section on its Google Play page, though I have no idea how reliable that is).

I installed it yesterday. I'm not hating it but not sure if I like it. It's very minimal. Like you don't even see the notification bar from the home screen and are limited to putting 8 apps on there (after you adjust the setting from 4). Everything else is on an alphabetical list, which has forced me to remember the names of apps instead of just remembering the icon and position I gave it in Nova. But it might just be something I need to get used to, so I'll give it some more time.
