Crane — Posture Reminder

Your posture coach that never phones home.

Crane tracks your posture in real-time using on-device machine learning — no cloud, no servers, no data ever leaves your machine.

Get gentle nudges when you slouch, follow guided ergonomic cycles (sit → stand → stretch → walk), practice guided breathing exercises, and track your posture score — all without a $99 wearable or a $20/month subscription.

A single purchase — not a subscription — keeps everything you tried unlocked, permanently. Use it on up to 5 devices.

WHY CRANE?
• Private by design — posture detection runs entirely on-device via TensorFlow.js. Zero network calls. Your webcam feed is never recorded or transmitted.
• Cheaper than hardware — Upright Go costs $79+. Crane is one payment, yours forever.
• No subscription tax — Competitors charge $10–20/month. Crane never charges you again after the one-time purchase.
• Built for knowledge workers — Designed for developers, designers, gamers, and anyone who sits 8+ hours a day.

HOW IT WORKS
1. Grant camera access (processed locally, never stored)
2. Crane's on-device model detects your head, neck, and shoulder position in real-time
3. A posture score updates live — green (good) to red (poor)
4. Get gentle alerts when your posture drops for too long
5. Follow ergonomic cycles: alternating sit, stand, stretch, and walk activities, plus guided breathing sessions

ENTERPRISE-FRIENDLY
100% offline processing. No cloud dependencies. No data collection. IT departments can approve Crane without privacy concerns.
