We use this only to manage your waitlist place. No ads, no data sale — same rules as the app.
What the Ring Reads
HRV Tracking
Heart-rate variability against your own 7-day baseline — the standard signal for autonomic load, read as a trend, never a diagnosis.
An invitation on your terms
Optional signals can guide the pace of an invitation within the permissions you choose. A signal never decides how you feel.
7–10 Day Battery
Wireless charging case. Wear it through workouts, sleep, and daily life without interruption.
5-ATM Water Resist
Swim, shower, and train. Full waterproofing at 50 metres depth.
Local Encryption
All biometric data is AES-256 encrypted on-device. Never sold. Never uploaded without consent.
iOS & Android
Seamless pairing. Real-time HRV view, sleep rhythm, and Yōkai companion sync.
