On-Device Safeguarding • HarmBlock
Parents shouldn't have to become technology experts to keep their children safe.
HarmBlock® is the world's first Safe-by-Design AI that helps prevent children from seeing, filming, and sharing explicit content - quietly, privately, and in real-time.
Built into the device. Not added afterwards.
Meet HarmBlock
Unlike traditional parental controls, HarmBlock helps prevent harmful content before it can be seen, filmed, or shared. Protection works quietly in the background, with no complicated setup and no reliance on constant parental intervention.
Privacy
Everything happens on the device. No cloud connection required.
Images remain on the device and are never uploaded for analysis. HarmBlock is designed to protect children while respecting their privacy, dignity, and independence.
Children experience online harm through cameras, messaging apps, social media, and livestreaming. HarmBlock can be embedded directly into devices, operating systems, apps, and platforms, creating protection from the moment a device is activated.
