Route 1: Uninstall the app
Procedure: Long-press the parental control app icon. Tap Uninstall or drag to the Uninstall area at the top of the screen. Confirm.
Bark
Bark prompts for a parent passcode on uninstall attempts. The passcode requirement is the only enforcement layer. If the child knows or obtains the passcode, the app uninstalls. Verdict: Fails.
Qustodio
Qustodio uses Device Admin status to block uninstall, similar to Bark. The bypass surface is the same: passcode required for direct uninstall, with documented workarounds in public forums for clearing app data through Settings to achieve the same effect. Verdict: Fails.
Family Link
Family Link blocks uninstall on supervised accounts through age 17, with parental approval required to end supervision. Supervision ends automatically when the supervised user reaches 18 per current Google policy. The age-based end condition is the protection, not a technical enforcement layer that holds regardless of age. Verdict: Fails.
Anchor
Anchor registers as a Device Admin during setup. Android recognizes Device Admin status at the OS level and refuses the uninstall request. Clearing app data through Settings produces the same OS-level rejection. The child cannot uninstall Anchor without the parent passcode. Verdict: Holds.
