Privacy Policy
- Introduction: Your Data, Your Territory
At Sanislink, we don’t just “respect” your privacy—we engineer it. We are building the first User Sovereign Health Infrastructure. Unlike traditional wearables that treat your data as their product, we treat your biometric data as your asset.
This Privacy Policy explains how we collect, use, and—most importantly—how we cryptographically protect your information. By using Sanislink, you are not just a user; you are a node, and we are the infrastructure providers protecting your sovereignty.
- Data We Collect
We collect information in three distinct layers:
- Identity Data (The Basics): Name, email address, shipping address, and payment information needed to deliver your hardware and manage your subscription.
- Biometric Data (The Health Metrics): Heart rate, blood oxygen (SpO2), sleep patterns, steps, and skin temperature collected by the ring sensors.
Crucial Distinction: This raw data is processed locally on your device or smartphone.
- Network Data (The DePIN Interactions): Digital wallet addresses (if connected), node activity logs, and referral codes used for the “Genesis Node Captain” program.
- The ZK Difference
This is where Sanislink differs from every other wearable on the market.
On-Device Encryption: Your raw biometric data is encrypted on your device. The private keys never leave your control.
Zero-Knowledge Proofs (ZK-Proofs): When you opt-in to research or data monetization, we do not upload your raw data. Instead, we generate a cryptographic proof (a “mathematical noise”) that verifies a statistical trend exists without revealing the underlying personal data.
We Sell Signals, Not Secrets: We may sell aggregated, anonymous statistical signals to research institutions. Buyers can verify the data’s authenticity mathematically, but they can never reverse-engineer it to find you.
- How We Use Your Information
To provide Pro Membership services (AI insights, trend analysis).
To calculate and distribute Sanis Points and Network Rewards.
To process orders and manage the 1-Year Warranty.
Only with your explicit consent: To include your anonymous signals in medical research projects.
- Sharing & Third Parties
No Data Selling: We never sell your personal identity or raw health data to advertisers.
Service Providers: We share necessary data with payment processors (e.g., Stripe) and logistics partners to ship your ring.
Legal Requirements: We may disclose data if compelled by law, but because we do not hold your private keys, our ability to decrypt your historical health data for authorities is technically limited.
- Your Rights
Under GDPR, CCPA, and the Sanislink User Sovereignty Charter, you have the right to:
Access: View the data we hold.
Withdraw Consent: Stop sharing data for utility contribution/points at any time.
Erasure: Request deletion of your account. Note that data already cryptographically committed to a decentralized blockchain ledger cannot be deleted, but it is anonymous.
Portability: Export your health data.
- Children’s Privacy
Sanislink is not intended for children under 13. We do not knowingly collect data from minors.
