4. Data Sharing and Clinic Association

We do not sell, rent, or trade your personal data. Your data is shared strictly under the following conditions:

• Your Clinic/Doctor: If you explicitly enter a Clinic Code during onboarding, your profile and progress charts are shared with the doctors associated with that specific clinic so they can monitor your therapy.
• Infrastructure Partners: We use industry-standard cloud and auth services (like AWS Lambda, Supabase, and Clerk) to host database tables and authenticate sessions securely.
