How each app handles uninstall attempts
Qustodio
Qustodio uses Device Admin status to block uninstall. Standard Android uninstall attempts are rejected at the OS level, same baseline as Anchor and Bark. Where Anchor adds the watchdog backstop: the continuous permission watchdog detects tampering attempts and re-prompts the child to restore the enforcement state. Anchor's architecture closes the silent-bypass gap that Qustodio's product positioning does not explicitly defend against.
Anchor
Anchor enrolls as Device Admin during setup, same foundation Qustodio uses. The continuous permission watchdog runs on top of that foundation. Any revocation attempt is detected within seconds, the child is re-prompted to restore the permission, and the parent feed surfaces every attempt as a tamper event. The silent-bypass gap is closed at the architecture level.
