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.
