Dear all,
I am still looking for the bast AppLock app without ads, as less tracker as possible and MOREOVER an app which prevent app to be uninstall… Ideas 
?
Thanks
search in f-droid, there is a nice one. https://f-droid.org/app/io.github.subhamtyagi.privacyapplock
I knew it, but this app do not prevent uninstallation !
Indeed. I guess you need to have root access in order to make this app a System app instead of a User app. This would make it non-uninstallable. I don’t know more about it.
with a good launcher you can hide it 
Like which one???
Total launcher, Nova launcher and I’m not sure with launchair
