Where is parental control on Android?
Android has no single Parental Control switch in Settings. The nearest things are Parental controls inside the Google Play Store settings and the Family Link app. Skie works differently: you manage the child's device from a web dashboard in a browser, and the rules are enforced on the device by Android itself.
Parents open Settings looking for a Parental Controls item and often cannot find one. On many phones there is a Digital Wellbeing and parental controls section, which leads to Family Link. Separately, the Play Store has its own Settings and then Family, then Parental controls, where you can limit content by age rating with a PIN.
Those two places cover app and content ratings. They do not stop a child from removing an app, using another browser, or turning on a VPN.
With Skie there is nothing for the child to find in Settings, because the rules are applied by the device owner. You manage the device from the Skie parent dashboard in a web browser. There you choose apps, set study and bedtime windows, see location, lock the device and release the controls if you ever need to.
The child sees the phone is managed, and some Settings items are greyed out, such as factory reset and developer options. That is intended.
Tip: if you only want a quick filter on Play Store downloads while you decide, use the built-in Play parental controls with a PIN the child does not know. Treat it as a first step, not the whole answer.
