Everyone knows all the apps on your phone

It requires root, but you can block/spoof this with an LSPosed[1] module such as XPrivacyLua[2]. I hear there's also the closed-source AppOps[3], but I've never used it.

I've not heard of XPrivacyLua, which is by the same author of the excellent NetGuard[0], which I've been using for years.

Interestingly XPrivacyLua is not supported anymore and the pro companion app will be removed from the Play store by Google because it uses the permission QUERY_ALL_PACKAGES.[1]

Indeed, it is a shame. However, XPL-EX is a fork (though with much internal code (re)written at this point) with even more capability, while maintaining the familiar and simple UI. Seems pretty neat!
