ShiseiKeeper — A free app that monitors your posture during desk work

A web app that monitors your posture while working at your desk using your PC camera and sends you a gentle notification the moment your posture breaks down.

6 detectable posture types

• Posture breakdown (slouching, forward lean, sliding down, shoulder tilt, neck tilt)
• Long-duration sitting / Long-duration away from desk
• Elbow resting / Face touching / Smartphone operation

What we prioritized most
We process only skeletal keypoints (point positions) within the browser. No video or coordinate data is sent externally—0 bytes. We don't identify faces or record anything. Since the backend has no posture data storage, there's no server or database.

How to use
Allow camera → Record baseline posture for 3 seconds → Then it monitors. Takes 10 seconds total, no installation or registration required.

Pricing
Free up to 1 hour per day (resets daily at midnight, no feature restrictions). For those who want to remove the limit, there's Pro (¥1,980 one-time purchase, no auto-renewal).
