## Part 2: Dozzi App & Device

The following sections apply specifically to the Dozzi baby monitor mobile application for iOS and watchOS, the Dozzi hub device, and the related cloud services that power alert routing and monitoring.

### What Dozzi Does

Dozzi is a smart baby monitor system. A hub device in your baby's room detects infant crying and sends alerts to caregivers via Apple Watch haptic vibrations. When multiple caregivers are set up, the App uses health and biometric data to determine which caregiver is most awake and routes the alert to them — letting the other caregiver continue sleeping.

### Information the App Collects

**Account Information**

- Name, email address, and password (via Firebase Authentication)

- Caregiver role and household setup (e.g., which caregivers are linked to which hub)

**Health and Biometric Data**

When you enable monitoring with an Apple Watch, we collect:

- **Heart rate** — sampled approximately every 30 seconds in Smart Mode or every 60 seconds in other alert modes, from Apple Watch via Apple HealthKit

- **Heart rate variability (HRV)** — used to assess sleep depth

- **Motion and movement data** — from Apple Watch accelerometer, processed into movement intensity scores used to detect wakefulness

- **Watch battery level** — monitored during sessions to alert you if battery is low

This data is used to calculate a "wakeability score" that determines which caregiver is most alert when your baby needs attention.

We access health data through Apple HealthKit with your explicit permission. The App uses a HealthKit workout session on your Apple Watch to maintain continuous heart rate sensor access during overnight monitoring — no workout data is saved to your Apple Health records. You can revoke HealthKit access at any time in your iPhone's Settings > Privacy & Security > Health > Dozzi.

**Device Information**

- **Device identifiers** — Firebase Cloud Messaging (FCM) tokens and Apple Push Notification Service (APNs) tokens, used to deliver cry alerts to your iPhone and Apple Watch

- **Device model and OS version** — for compatibility and debugging

- **Hub device identifier** — MAC address of your Dozzi hub, used to associate your account with your hub

**Hub Telemetry Data**

The Dozzi hub periodically reports operational metrics to our cloud backend:

- **WiFi signal strength (RSSI)** — used to monitor hub connectivity health

- **Ambient noise level** — averaged sound level in the baby's room (no audio is recorded or stored)

- **Near-miss count** — number of times the baby fussed but self-soothed without triggering an alert

**Monitoring and Alert Data**

- **Cry detection events** — timestamps, duration, and intensity level of detected crying. No audio is ever recorded, transmitted, or stored.

- **Alert routing decisions** — which caregiver was alerted, the wakeability scores and sleep state factors used in the decision, and whether alternating or smart routing was applied

- **Session data** — monitoring start/stop times, session duration, and alert counts

- **Response data** — whether and when an alert was acknowledged or snoozed

- **Proximity data** — Bluetooth signal strength (RSSI) between your Apple Watch and the hub, used to determine if a caregiver is already near the baby

**Bluetooth Beacon Proximity Data**

- **Beacon region monitoring** — The App uses Bluetooth beacon technology (iBeacon) to detect when your iPhone is near the Dozzi hub. This is used solely to keep the monitoring connection reliable overnight, allowing the App to automatically reconnect if the connection is interrupted. This feature uses your device's Bluetooth hardware to detect the hub's beacon signal — **it does not use GPS, cellular location, or Wi-Fi location services. No geographic location data is collected, stored, or transmitted.** The App requests location permission because iOS requires it for Bluetooth beacon detection, but no actual location information is accessed or recorded.

**Feedback Data**

When you submit beta feedback through the App, we collect:

- Your rating, selected tags, and written comments

- Session context (duration, alert count, sleep score, alert mode)

- App version and hub firmware version

- Optionally, a diagnostic debug report containing a summary of your monitoring session (see Diagnostic Data below)

**Diagnostic Data**

- App crash logs, error reports, and performance metrics

- Debug reports (generated on-demand by the user) containing monitoring session summaries. When submitted with beta feedback, debug reports are uploaded to our cloud backend. Debug reports do not contain raw biometric data — only aggregated session statistics.

### How the App Uses Your Information

| Data | Purpose |

|------|---------|

| Heart rate, HRV, motion | Calculate wakeability scores for intelligent alert routing (Smart Mode) |

| Watch battery level | Alert you if watch battery is low during a monitoring session |

| Device tokens (FCM/APNs) | Deliver cry alert notifications to your iPhone and Apple Watch |

| Account info | Manage your account, link caregivers to hubs |

| Hub telemetry (WiFi RSSI, ambient noise, near-miss) | Monitor hub health, improve cry detection algorithms |

| Cry detection events | Route alerts, generate session summaries and sleep analytics |

| Alert routing decisions | Improve fairness of alert distribution between caregivers |

| Proximity data | Suppress follow-up alerts when a caregiver is already near the baby |

| Beacon proximity | Keep the monitoring connection reliable overnight by detecting when your phone is near the hub (no GPS or location tracking) |

| Feedback data | Improve app reliability and user experience during beta testing |

| Diagnostic data | Debug issues, improve app reliability |

**We do NOT use your health or biometric data for advertising, marketing, or data mining. Ever.**

### Biometric Data — BIPA Disclosure

If you are a resident of Illinois, the Illinois Biometric Information Privacy Act (BIPA) provides you with specific rights regarding biometric data. This section serves as our written notice under BIPA.

**What biometric data we collect:** Heart rate, heart rate variability, and wrist motion data from your Apple Watch.

**Purpose of collection:** To calculate wakeability scores that determine which caregiver receives cry alerts during Smart Mode routing. This data is used solely for app functionality — not for identification, authentication, advertising, or sale.

**Consent:** We obtain your informed, electronic consent before collecting any biometric data, through our in-app Biometric Data Consent screen presented during onboarding. You must affirmatively tap "I Consent" before any health data is accessed.

**Retention and destruction schedule:**

- **Real-time biometric readings** (heart rate, HRV, motion): Retained in our cloud database for up to **7 days**, then archived to secure cloud storage for up to **90 days** for incident investigation (or until you delete your account, whichever is sooner), then permanently deleted

- **Nightly baseline calculations**: Recalculated from the most recent **7 days** of data; older data is not retained for baseline purposes

- **Aggregated analytics** (daily and weekly summaries, not raw biometric data): Retained for the lifetime of your account

- **Anonymized algorithm data** (if you opt in): De-identified data with no personally identifiable information, retained permanently (see Optional Algorithm Contribution below)

- **On account deletion**: All identifiable biometric data associated with your account is permanently deleted within **30 days**

- **Maximum retention**: If you stop using Dozzi, identifiable biometric data is permanently deleted no later than **3 years** after your last monitoring session

**Your rights under BIPA:**

- You may revoke your biometric data consent at any time in the App under Settings

- Revoking consent disables Smart Mode alert routing; the App will fall back to Alternating mode

- You may request deletion of all biometric data by contacting us at info@dozzisleep.com

- We will never sell, lease, trade, or otherwise profit from your biometric data

- We will never disclose your biometric data to third parties without your consent, except as required to provide the service (see below) or as required by law

### Optional Algorithm Contribution

During onboarding, you may optionally opt in to contribute anonymized, de-identified biometric patterns to help improve Dozzi's sleep detection algorithms. If you opt in:

- Your data is anonymized using a one-way cryptographic hash (SHA-256) before storage, removing all personally identifying information including your name, email, device identifiers, and hub ID

- Anonymized nightly summaries (such as sleep stage percentages, alert counts, response times, and cry event statistics) are stored permanently in a secure analytics database (Google BigQuery)

- No raw biometric readings (individual heart rate samples, HRV values, or motion data) are included — only aggregated per-night statistics

- Used solely to improve sleep stage detection and alert routing accuracy

- You can opt out at any time in Settings; opting out stops future data from being anonymized and stored, but previously anonymized data cannot be linked back to you and is not deleted (as it contains no identifying information)

This is entirely optional and does not affect your use of the App.

### Data Storage and Retention

Dozzi uses a three-tier data storage system designed to balance real-time performance, incident investigation, and long-term algorithm improvement:

|------|---------|-----------|-------------|---------|

**Detailed retention by data type:**

| Data Type | Retention Period |

|-----------|-----------------|

| Account information | Until you delete your account |

| Heart rate, HRV, motion (cloud database) | 7 days, then archived |

| Archived biometric data (cloud storage) | Up to 90 days, or upon account deletion, whichever is sooner |

| Nightly baseline | Rolling 7-day recalculation |

| Monitoring session records | Until you delete your account |

| Cry alert audit logs | Until you delete your account |

| Daily and weekly analytics | Until you delete your account |

| Milestone and badge data | Until you delete your account |

| Feedback and debug reports | Until you delete your account |

| Hub telemetry (WiFi RSSI, noise, near-miss) | Included in audit logs; same retention as audit logs |

| Device tokens | Updated on each app launch; deleted on account deletion |

| Anonymized algorithm data (BigQuery, opt-in) | Permanent; cannot be linked to you |

### Deleting Your Data

- **Delete your account**: Go to Settings > Account > Delete Account in the App. All identifiable cloud data associated with your account — including biometric readings, session records, alert logs, analytics, feedback, and your user profile — will be permanently deleted within 30 days. Anonymized data in BigQuery (if you opted in) is not deleted, as it cannot be linked back to you.

- **Revoke HealthKit access**: Go to iPhone Settings > Privacy & Security > Health > Dozzi and disable access. This stops new data collection but does not delete previously collected cloud data.

- **Request manual deletion**: Email info@dozzisleep.com to request deletion of specific data or to verify that your data has been fully removed.

### Third-Party Service Providers

In addition to the third parties described in Part 1 for our store, the Dozzi App shares information with the following service providers solely to operate the monitoring service:

| Provider | Data Shared | Purpose |

|----------|------------|---------|

| **Google Firebase** (Firestore, Cloud Functions, Authentication, Cloud Messaging) | Account info, biometric data, device tokens, session data, feedback | Cloud backend — data storage, alert routing logic, push notification delivery, user authentication |

| **Google Cloud Storage** | Archived biometric data (7–90 days old) | Secure cold storage for incident investigation |

| **Google BigQuery** | Anonymized nightly summaries (opt-in only) | Algorithm improvement analytics — no PII |

| **Apple Push Notification Service (APNs)** | Device tokens, alert payloads | Deliver cry alerts directly to Apple Watch |

| **Apple HealthKit** | Health data read with your permission | Source of heart rate, HRV, and motion data (data stays on-device in Apple Health; we read it with your permission) |

These providers process data under their own security and privacy commitments:

- [Google Cloud Privacy](https://cloud.google.com/privacy)

- [Apple Privacy Policy](https://www.apple.com/legal/privacy/)

### Data Security

We implement the following security measures to protect your data:

- **Encryption in transit**: All data between your devices and our cloud backend is transmitted over HTTPS/TLS

- **Encryption at rest**: Data stored in Google Firebase and Google Cloud Storage is encrypted at rest using AES-256

- **Anonymization**: Algorithm contribution data is anonymized using SHA-256 cryptographic hashing before storage in BigQuery, making it impossible to link back to you

- **Access controls**: Biometric data is accessible only through authenticated cloud functions; there is no general-purpose database access

- **Authentication**: User accounts are secured through Firebase Authentication with Apple Sign-In support

- **No audio storage**: The Dozzi hub detects crying events but does not record, transmit, or store audio. Only cry detection metadata (timestamp, duration, intensity) is sent to the cloud.

- **Local hub communication**: Communication between your iPhone and the Dozzi hub occurs over your local WiFi network. No audio data passes through the internet.

### Push Notifications and Critical Alerts

Dozzi uses push notifications to deliver cry alerts. With your permission, we use Critical Alerts (approved by Apple) that can bypass Do Not Disturb and silent mode to ensure you are notified when your baby needs attention.

- You can manage notification preferences in iOS Settings > Notifications > Dozzi

- Disabling notifications may prevent cry alerts from reaching your devices

- Alert delivery relies on device tokens stored in our cloud backend
