Gentle, adaptive reminders. No uploads. No tracking.
Designed to protect you, not surveil you
Every feature runs locally. We've built the things an ergonomics coach would notice - without ever watching you back.
Real-time posture coach
MediaPipe pose + face landmarks detect slouching, head tilt, and neck compression. Gentle reminders nudge you back to a healthy stance.
Screen distance monitor
Calibrates to your setup with a quick card-hold so it reports actual centimetres, not guesses. Alerts if you lean too close.
20-20-20 breaks
Every 20 minutes, ScreenGuardian prompts a 20-second look at something 20 feet away - the best-studied defence against eye strain.
Habit alerts
Optional nail-biting and face-touching detection surface unconscious habits so you can course-correct.
Insights that stay yours
Pro unlocks local SQLite history, trendlines, and dashboards - always on your device, never uploaded.
Zero cloud. Zero tracking.
No frames, no events, no behavioural profiles ever leave your machine. The only outbound requests are update checks.
Privacy commitment
Safeguarding your posture should never come at the cost of safeguarding your privacy.
On-device AI
Posture and distance detection run locally with MediaPipe. Your machine is the only computer that ever sees your webcam.
Zero cloud storage
There is no server that stores your frames, events, or metrics. Nothing to leak, because nothing is uploaded.
No tracking
No analytics SDKs, no third-party scripts on the website, no behavioural profiling in the app. Period.
