Privacy Policy
Introduction: Your Data, Your Territory
At Sanislink, we engineer privacy by design. We are building a Self-Custodial Wellness Network where your biometric data remains your private asset — never a product to be sold.
This Privacy Policy explains how we collect, use, and protect your information. By using Sanislink, you are choosing a privacy-first approach to wellness technology.
1. Data We Collect
We compartmentalize your information into strictly isolated layers:
- (a) Commerce & Referral Data: Name, email, shipping address, and payment information (processed securely via Stripe for credit cards and HSA/FSA accounts), along with referral codes for our partner program.
- (b) Raw Biometric Data: Heart rate, blood oxygen (SpO₂), sleep patterns, and skin temperature collected by the Sanislink Ring sensors. Important distinction: This raw data is processed locally on your device and never leaves your ring in identifiable form.
- (c) Synthetic / Anonymized Data: If you explicitly opt-in, only non-identifiable wellness insights and aggregated signals are transmitted to our secure vault to generate AI insights and rewards.
2. The Sanislink Architecture Difference
Physical & Logical Isolation: Your synthetic data is stored in a dedicated, privacy-focused vault that is physically and logically separated from our AI processing systems. Your raw biometric data is never accessible to our team or any third party.
We Analyze Signals, Not Secrets: We may use fully anonymized, aggregated statistical trends for internal improvements and scientific research. These signals cannot be reverse-engineered to identify any individual.
3. How We Use Your Information
- To securely process your hardware orders and payments (including HSA/FSA compliance).
- To calculate and distribute referral commissions and Sanis Points.
- To deliver Pro Membership services, including AI-driven wellness insights.
- Only with your explicit consent: To include fully anonymized synthetic signals in voluntary scientific research contributions.
4. Sharing & Third Parties
No Data Selling: We do not sell your personal information or raw health data to data brokers or advertisers.
Service Providers: We share only the minimum necessary data with trusted partners (such as Stripe for payments and fulfillment partners for shipping) solely to fulfill your orders.
Legal Requirements: We may disclose information if required by law. However, because we do not hold your private keys for raw biometric data, our ability to provide decrypted historical health records is technically limited.
5. Your Rights
Under global privacy laws (including GDPR and CCPA), you retain strong control over your data:
- Right to Erasure: You can permanently delete all your data at any time using the “Delete All My Data” function in the App.
- Withdraw Consent: You may revoke consent for data contribution or research participation at any time.
- Access & Portability: You can view and export the synthetic data stored in your vault.
6. Children’s Privacy
Sanislink is not intended for children under 13. We do not knowingly collect or process personal data from minors.
