Anbu ("we," "us," or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, store, and protect information when you use the Anbu mobile application (the "Service"). By using the Service, you agree to the practices described in this policy.
We designed Anbu with a privacy-first approach. We do not collect personal information such as your name, phone number, email address, or location. The Service operates using only device-level identifiers and minimal sensor data necessary for wellness check functionality.
| Category | Data | Purpose |
|---|---|---|
| Device Information | Device identifier (device_id), platform (Android/iOS), OS version, timezone | Service operation and device identification |
| Push Token | Firebase Cloud Messaging (FCM) token | Delivering wellness check notifications and alerts |
| Wellness Data (Subject) | Battery level, heartbeat transmission time | Determining wellness status and sending guardian alerts |

| Location Data (Subject, Optional) | Latitude, longitude, accuracy radius, and timestamp | Provided one time to connected guardians only when the subject directly taps the [🚨] emergency help button. Not collected during routine wellness checks. If location permission is denied or GPS is unavailable, the emergency notification is still delivered without location data. |
| Subscription (Guardian) | In-app purchase receipt (Apple/Google) | Subscription verification and service access |
Payment Method Information — Not Stored on Our Servers
The only payment-related data stored on our servers is the receipt validation token issued by the Apple App Store or Google Play Store. Card numbers, bank account information, payment credentials, and billing addresses are processed exclusively within Apple's and Google's payment systems and are inaccessible to our servers. All payment data storage, refund handling, and billing dispute resolution are governed entirely by Apple's and Google's respective policies.
We use the collected information solely for the following purposes:
