How can I track my child's location without them turning it off?
Use a tool that sits below the child's reach, such as Skie running as the Android device owner. The location permission is held by Skie, not by a setting the child can flip, and the device is open about being managed, so tracking is visible and agreed rather than secret.
The usual way kids defeat tracking is simple. They revoke the location permission, log out of the app, or uninstall it. Family-sharing apps depend on the child leaving those settings alone, which is a lot to ask of a teenager with a grudge.
Skie takes a different route. It is installed as the Android device owner on the family's own phone or tablet, which is only possible on a device that has been freshly set up or reset. From there, Skie grants the location permission itself and blocks the settings that would remove it.
That does not make tracking secret, and it should not be. The phone shows that it is managed, and there is no hidden mode. Skie does not read messages or record calls, audio or video. It is location, apps, websites and schedules, and your child can see that.
It also does not replace talking. A device left at home still shows up at home. A child who wants privacy from you will find ways, so the best protection is a child who accepts the reason for tracking. Plan the conversation before you set it up.
Compared with the free Google Family Link, which relies on a supervised account and app-level settings, Skie's control comes from device owner mode. Family Link has features Skie does not, such as screen time limits. Skie has the stronger enforcement.
