STEADYWATCH™ — Atomic Clock Multi-Tool

Effective Date: March 21, 2026

Last Updated: May 9, 2026

Publisher: Quantum V^ LLC

App Version: 1.0.13

Introduction

STEADYWATCH™ ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use the STEADYWATCH™ app (the "App") on Apple Watch and iPhone.

STEADYWATCH™ captures your biological oscillation frequency via Apple Watch motion sensors, combines it with pre-computed IBM quantum hardware entropy, and generates a cryptographic identity key authorized by Face ID and signed by the Secure Enclave — all on your device.

By using our App, you agree to the collection and use of information in accordance with this policy.

Information We Collect

1. Motion and Biometric Frequency Data

What We Collect:

How We Use It:

Storage: Raw motion sensor data is not stored. Only the derived biometric key (a cryptographic output) is saved locally on your device. No raw IMU data is transmitted or retained.

2. Biometric Key and Cryptographic Identity

What We Generate and Store:

How We Use It:

Storage: Biometric keys are stored locally on your device. Keys may optionally sync to a local network server you configure (e.g., on your home network). Keys are never transmitted to Quantum V^ LLC servers or any third-party cloud service.

3. Face ID Authorization

What We Use:

What We Do NOT Use:

How It Works: Face ID is used exclusively as an authorization gate. When you authorize a key, the Secure Enclave's P256 private key signs the biometric key hex string. The signing key never leaves the Secure Enclave chip. The resulting ECDSA signature is what is stored — not any facial data.

4. IBM Quantum Hardware Entropy

What We Use:

What We Do NOT Do:

5. Local Network Communication

What We Use:

What We Do NOT Do:

Your Control: Local network sync is user-configured. If you do not configure a backend URL, all data remains on-device only.

What We Do NOT Collect

We do NOT collect:

Third-Party Services

Apple Services Used

These services are subject to Apple's Privacy Policy: Apple Privacy Policy

IBM Quantum (Pre-Computed Entropy Only)

THE VAULT™ entropy was generated on IBM Quantum hardware (ibm_marrakesh) in a one-time seed run. This entropy is embedded in the App at build time. The App does not connect to IBM at runtime. IBM's privacy practices are not applicable to App users.

Children's Privacy

Our App is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us.

Medical Disclaimer

Important: STEADYWATCH™ is for cryptographic identity and informational purposes only. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or medical condition. Always consult qualified healthcare professionals for medical decisions.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Changes will be reflected by updating the "Last Updated" date at the top of this page. Significant changes will be noted in the App Store release notes. You are advised to review this policy periodically.

Data Retention

International Users

Data is stored locally on your device in your jurisdiction. We do not transfer data across international borders. Your data is subject to the laws of your jurisdiction.
