Can you delete a parental control app?
With most apps, yes: a child can often uninstall it, force stop it or clear its data. With Skie, no. Uninstall is blocked, force stop and clear data are blocked, and the app cannot be stopped by the child. Only the parent can remove Skie, from the dashboard, using Remove Skie.
Ordinary parental control apps live in the same space as any other app. Many ask the child's permission through a device administrator setting, which is itself a setting the child can turn off, sometimes after a short wait.
Skie works as the Android device owner. Android does not let a device owner app be uninstalled by the user, and Skie also blocks force stop, clear data and disable on the apps it manages. The app cannot be stopped by the child.
Other routes to the same result are closed too. Factory reset from Settings is blocked. So are safe mode, developer options and adb, adding new users, work profiles and installing from unknown sources. If someone resets from the recovery menu, Android's Factory Reset Protection is on, so the wiped device asks for the Skie organisation's Google sign-in before it can be set up again, which only Skie holds. A reset device is of no use to whoever took it.
If you want to remove Skie yourself, say when a child grows up or you sell the device, use Remove Skie on the dashboard. It turns off every protection, shows every app again, restores DNS and releases ownership. It does not delete any apps.
Tip: tell your child that you can lift the controls later. Children behave differently when they know a rule can end.
