## 2. Privacy-First & Offline Local Storage
HabitFlow is designed as an **offline-first, privacy-focused application**.

- **No Personal Accounts Required**: You do not need to create an account, register an email address, or provide any personal identification to use HabitFlow.

- **No Remote Health Data Uploads**: Your habit records, fitness activity, and step metrics are **never uploaded** to remote servers or cloud databases operated by us.

## 3. Device Permissions & Usage Purpose
To deliver its core habit tracking and fitness step counter functionality, HabitFlow requests the following Android device permissions:

| Permission | Technical Name | Purpose in HabitFlow |
| :--- | :--- | :--- |
| **Physical Activity / Step Counter** | `android.permission.ACTIVITY_RECOGNITION` | Reads the device's hardware step sensor to track daily step counts, calculate distance (`km`), estimate active calorie burn (`kcal`), and classify walking/running cadence on-device. |
| **Notifications** | `android.permission.POST_NOTIFICATIONS` | Displays local scheduled habit reminder notifications configured by you. |
| **Exact Alarms & Timers** | `android.permission.SCHEDULE_EXACT_ALARM` | Triggers exact daily local habit reminders and automates the 12:00 AM midnight step reset worker. |
| **Boot Completed** | `android.permission.RECEIVE_BOOT_COMPLETED` | Reschedules your local habit reminder alarms automatically if your phone restarts. |
| **Vibration Control** | `android.permission.VIBRATE` | Provides subtle haptic feedback when you check off habits or reach step milestones. |

*None of the data accessed via these permissions is transmitted or sold to third parties.*
