We NEVER sell your personal data to third parties.
4. Generative AI (Faith Assistant)
The FaithFlow app includes a generative AI feature called Faith Assistant, powered by Anthropic Claude. Things to know:
- Each of your messages is sent to Anthropic servers (outside Indonesia) to generate the response.
- AI responses may contain errors, bias, or inaccurate information. AI is NOT a substitute for spiritual guidance from qualified pastors or pastoral staff.
- You can report inappropriate, offensive, or harmful AI responses via the long-press context menu on a message, or through Settings > Faith Assistant > Report a Problem.
- Conversation history is stored on our servers for context. You can clear all history at any time.
- We do not use your conversations to train AI models.
5. Face Recognition & Biometric Data
The kiosk check-in feature uses optional face recognition:
- You MUST give explicit consent before face data is enrolled for the first time.
- We store embeddings (mathematical representations), NOT your face photos. Embeddings cannot be reversed back to photos.
- Embeddings are encrypted at rest and transmitted only over HTTPS.
- Biometric data is NEVER shared with any third party.
- You can delete biometric data at any time via Settings > Privacy > Delete Biometric Data. After deletion, check-in reverts to manual.
6. Mobile App Permissions (Android)
The FaithFlow app requests the following permissions, only when needed for features you use:
- Camera: Profile photos, child dedication photos, and face-recognition check-in.
- Microphone: Faith Assistant voice mode + LiveKit voice calls for remote counseling.
- Media storage (photos/videos/audio): Select a profile photo from your gallery.
- Notifications: Push notifications for events, prayer, and announcements.
- Device biometric (fingerprint/face): Quick login with device biometric (optional, stored ONLY on your device — never sent to our servers).
- Phone & phone state (LiveKit Telecom): Required for voice calls with pastoral staff.
Each permission can be denied or revoked at any time via Android Settings. Related features will be disabled but the app remains functional.
7. Donations & Payments (iPaymu)
Donations/giving via the app are processed by iPaymu (PT iPaymu Mitra Bisnis), a licensed payment gateway in Indonesia. Things to know:
- Payment details (card numbers, virtual accounts, e-wallets) are entered directly into iPaymu's system, NOT into our app.
- We only receive transaction success confirmation (status, amount, transaction ID) from iPaymu.
- Donation history is stored on our servers for tax reporting and church financial transparency.
- iPaymu's privacy policy is available at ipaymu.com/privacy-policy.
8. Third Parties & Cross-Border Data Processing
Our services use the following third parties. Some operate outside Indonesia:
- Anthropic Claude (USA): Faith Assistant generative AI.
- Groq (USA): Fast voice transcription for Faith Assistant voice mode.
- Expo Push Service (USA): Push notification delivery.
- iPaymu (Indonesia): Donation payment processing.
- LiveKit (USA): Real-time voice/video calls for counseling.

Each service has its own privacy policy. We choose partners that comply with international privacy standards (GDPR, CCPA).

11. Children
The FaithFlow app is intended for users aged 13 and above. We do not knowingly collect personal data from children under 13. If we learn that a child under 13 has registered, we will delete that account. For child dedication submitted by parents: the parent/guardian provides the child information, and that information is treated with high confidentiality.
