Privacy Policy
Aura Safety by First-24 Health LLC
Effective date: April 16, 2026
Last updated: April 16, 2026
First-24 Health LLC ("we", "our", "us") operates the Aura Safety mobile application ("the App"). This Privacy Policy describes how we collect, use, and protect information when you use Aura Safety.
Privacy-first design: Aura Safety processes your biological signature entirely on your device. Raw biometric data (motion, tremor, cardiac patterns) never leaves your phone. Only signed verification results — not the underlying biometric data — are transmitted.
1. Information We Collect
1.1 Information you provide directly
- Account data: name, email address, sign-in method (Apple ID, Google account, or magic link)
- Profile information: display name, optional phone number
- Family member contacts: names, phone numbers, relationships of family members you add
- Emergency contacts: names, phone numbers, emails of contacts you designate
- Meeting labels: optional text labels you assign to group verifications
1.2 Information collected automatically
- Motion sensor data (accelerometer + gyroscope): used on-device to compute your unique biological signature. Raw motion data is never transmitted.
- Location data (GPS): captured during ride monitoring, emergency SOS, and proximity verification. Shared only with your designated emergency contacts during active emergency events.
- Bluetooth and UWB ranging data: used for in-person family verification; processed on-device.
- Camera access: used only when scanning QR codes during proximity verification.
- Microphone access: used only when capturing audio evidence during duress events you initiate.
- Device identifiers: anonymous device ID for sync across your own devices, push notification tokens (FCM).
- Crash and diagnostic data: automatically reported via Sentry when the app crashes, helping us fix bugs.
- Usage analytics: anonymous app usage events via PostHog (which screens you visit, feature usage). Does not include biometric or location data.
1.3 Information we do NOT collect
- We do not collect or store your raw biometric data (tremor patterns, cardiac micro-motion, or fingerprints) on our servers.
- We do not access your contacts, photos, calendar, or files outside what is explicitly required for safety features and granted by you.
- We do not collect health records or medical data. Aura Safety is not a medical device.
- We do not sell your personal information to third parties.
2. How We Use Information
| Purpose | Data used |
| Verify your identity for account access | Email, sign-in tokens (Apple/Google) |
| Compute biological identity signature | Motion sensor data (on-device only) |
| Detect duress and dispatch silent SOS | Motion data, location, emergency contacts |
| Verify family member identity (Kin) | Verification results between enrolled family devices |
| Monitor rideshare safety | Location, optional driver/vehicle info you enter |
| Generate proximity meeting receipts | Bluetooth/UWB ranging data, biological verification results |
| Process subscription payments | Apple App Store / Google Play purchase tokens (via RevenueCat) |
| Send push notifications | Device push tokens (FCM) |
| Improve the app | Anonymous usage analytics (PostHog), crash reports (Sentry) |
3. Data Storage and Security
- On-device storage: baseline signatures, attestation records, evidence captures, family member info, and emergency contacts are stored locally in encrypted SQLite databases.
- Cloud storage: account information and synced records are stored on Supabase (PostgreSQL) with Row-Level Security ensuring you can only access your own data.
- Encryption: all data in transit is encrypted with TLS 1.2+. Sensitive cloud-stored data uses AES-256 encryption at rest.
- Cryptographic signing: evidence captures are HMAC-SHA256 signed and hash-chained for tamper-evidence.
- Hardware-rooted security: on iOS, signing operations use the Secure Enclave; on Android, hardware-backed Keystore where available.
4. Third-Party Services
We use the following third-party services to operate Aura Safety. Each has their own privacy policy:
5. Sharing Your Information
We share your information only in these limited circumstances:

- With your emergency contacts you have designated (location and status during active SOS events)
- With service providers listed in Section 4, only as needed to operate the app
- To comply with law when legally required by valid legal process
- To protect safety if we reasonably believe disclosure is necessary to prevent imminent harm
We do not sell your personal information.

11. Medical Device Disclaimer
Aura Safety is a personal safety platform. It is not a medical device. It does not diagnose, treat, cure, or prevent any disease. The biological signature analysis is solely for identity verification and duress detection — it is not a substitute for medical evaluation.
