Privacy Policy

Our Commitment

Causal is owned and operated by Berry Street Research Group LLC ("Berry Street," "we," "us," or "our"), located in New York, New York. Causal uses health and lifestyle data only to provide personal wellness insights inside Causal. We do not sell, rent, lease, broker, or use Apple Health data, biometrics, benchmark profile fields, or check-in answers for advertising, marketing, resale, or unrelated profiling.

1. Information We Collect

Causal collects the following data when you choose to use the related features:

• Apple Health data: Read-only sleep duration, resting heart rate, and Heart Rate Variability (HRV/SDNN), only after you grant HealthKit permission.
• Check-in answers: Responses to Causal prompts about mood and selected lifestyle factors such as caffeine, alcohol, sugar, stress, socializing, and workouts.
• Benchmark profile: Optional age, height, weight, sex assigned at birth, and unit preference, used to make wellness ranges more relevant.
• Account data: Firebase user ID, email address, authentication status, and Google Sign-In account identifiers if you choose Google Sign-In.
• App settings: Selected tracked factors, notification frequency, waking-hours window, privacy guard state, connected-source status, and generated insight records.

2. How We Use Data

• To authenticate your account and keep your Causal data associated with your account.
• To store check-ins, profile settings, HealthKit-derived biometric records, and generated insights for your use in the app.
• To run Causal's backend inference service and return personal wellness insights.
• To schedule local check-in notifications when you grant notification permission.
• To troubleshoot app or backend errors that affect your account.

3. HealthKit Boundaries

Apple Health access is read-only in the current iOS app. Causal does not write data to Apple Health. Causal asks only for sleep analysis, resting heart rate, and HRV because those signals support the wellness insights shown in the app.

• HealthKit data is not used for advertising, marketing, resale, or unrelated data mining.
• HealthKit data is not shared with advertisers, data brokers, or information resellers.
• You can revoke HealthKit access at any time in iOS Settings or the Health app.

4. Service Providers

Causal uses the following service providers to operate the app:

• Firebase Authentication: Account creation, email-link sign-in, and account session management.
• Google Sign-In: Optional sign-in method if you choose to continue with Google.
• Firebase Firestore and Google Cloud: Storage and processing for profile settings, check-ins, biometric records, insight records, and backend inference.

Causal does not include third-party advertising SDKs and does not use Firebase Analytics in the iOS app.

5. Retention and Deletion

We retain account, check-in, biometric, profile, and insight records while your account is active so the app can show history and generate insights. You can delete Causal data from the app's Pulse tab under Privacy & Data.

• Deleting Causal data removes local records on the device and supported Firebase/Firestore account records.
• Account deletion may require recent authentication before Firebase allows the account credential to be deleted.
• Backup copies, logs, or records required for security, fraud prevention, legal compliance, or dispute resolution may persist for a limited period.

6. Your Choices

• You can decline HealthKit permission and still use manual check-ins.
• You can change notification permission in iOS Settings and change check-in frequency in Causal.
• You can edit benchmark profile fields and tracked factors in Pulse.
• You can request help with access or deletion by emailing privacy@causal.fitness.

7. Children

Causal is not intended for children under 13. If you believe a child has provided data to Causal, contact privacy@causal.fitness so we can review and delete it.
