HarmBlock+ is a digital safety and parental control service that helps guardians manage their children’s HMD Fuse devices through the HarmBlock+ app. After creating an account and pairing the HMD Fuse device, guardians can monitor their child's device activity such as location, screen time, and step count, while also setting boundaries with features like School Mode, Bedtime Mode, app usage limits, contact permissions, timers, and notifications. Guardians are also able to control the HarmBlock AI solution, a pre-trained, self-contained AI protection system that blocks nude content from being displayed on the screen, captured by the camera, or stored on the device.
