1. Introduction & Scope
Welcome to Walk Tracker Pro ("we", "us", or "our"), an Android application published by Echo Virtual Support (Package ID: walk.tracker.pro).
We are committed to full transparency regarding how data is handled. This Privacy Policy outlines our data handling practices in strict compliance with the Google Play Developer Program Policies, specifically addressing the User Data Policy, Health and Fitness Policy, Data Retention Requirements, and Data Deletion Requirements.
2. Information We Collect & Access
Walk Tracker Pro operates primarily on an offline-first, on-device architecture. We access and process only the minimal information needed to calculate and display your physical fitness metrics:
A. Physical Activity & Sensor Data
- Step Counts & Cadence: Retrieved from your device's built-in step counter hardware sensor (
android.hardware.sensor.stepcounter) and step detector to calculate total daily steps, walking duration, and distance. - Activity Recognition: Uses Android's Activity Recognition system to determine physical movement status (walking, running, or resting).
B. Optional User Profile & Body Metrics
- Height, Weight, Age, and Gender: Users may voluntarily enter height (cm), weight (kg), age, and gender in the app's Profile section. This data is used solely to compute body mass index (BMI) zones and apply the standard MET (Metabolic Equivalent of Task) formula for calorie expenditure.
- Storage: These body measurements are stored strictly on your local device and are never transmitted to our servers or third-party databases.
C. Diagnostics & Crash Reporting
- Crash Logs: Through Firebase Crashlytics, we collect anonymous crash stack traces, device model, and operating system version to identify and fix technical software defects.
- Anonymous App Analytics: Through Google Analytics for Firebase, we collect aggregated usage statistics (such as screen visits and session lengths) to understand user engagement.
D. In-App Purchase Status
- Walk Tracker Pro uses the official Google Play Billing Library to verify digital subscription entitlement. We receive confirmation tokens from Google Play confirming active subscription status. We do not have access to or store your credit card numbers, bank information, or billing address.
3. Sensor Permissions & Foreground Services
To provide uninterrupted, accurate step counting without missing steps during everyday usage, Walk Tracker Pro requires the following Android permissions:
| Permission | Type | Justification & Purpose |
|---|---|---|
android.permission.ACTIVITY_RECOGNITION |
Runtime Permission | Mandatory on Android 10+ (API 29+) to access the device's hardware step sensor and count steps in real time. |
android.permission.FOREGROUND_SERVICEandroid.permission.FOREGROUND_SERVICE_HEALTH |
Foreground Service | Required under Android 14+ (API 34+) to maintain a persistent background step counting service. This prevents the Android operating system from killing step tracking when the screen turns off or while using other applications. A persistent, non-intrusive status notification is displayed while active. |
android.permission.POST_NOTIFICATIONS |
Runtime Permission | Allows the application to display the ongoing step counter notification, daily goal milestone alerts, and streak achievements. |
android.permission.RECEIVE_BOOT_COMPLETED |
Install-Time Permission | Automatically restarts the background step counter service when your device boots up so your step tracking continues without manual intervention. |
4. How We Use Information
All data processed by Walk Tracker Pro is used strictly to:
- Calculate and display real-time steps, walking distance (km/mi), active minutes, and estimated active calories burned.
- Provide daily, weekly, and monthly step history graphs and progress reports.
- Deliver personal achievement badges, streaks, and gamified XP level progression.
- Power the home-screen step counter widget (via Glance AppWidget).
- Validate PRO subscription features via Google Play In-App Billing.
- Identify software crashes and optimize stability.
5. Data Retention Policy
In accordance with Google Play's User Data policy regarding data retention disclosure, this section sets forth our exact data retention practices:
A. Local On-Device Data Retention
- Fitness, Step Counts & Profile Metrics: All step logs, walking history sessions, daily goals, and user body measurements (height, weight, age, gender) are stored exclusively in a local SQLite Room database on your physical device.
- Retention Period: This data is retained on your device only for as long as you choose to keep the Walk Tracker Pro app installed. If you uninstall the app or clear app data via Android settings, all stored fitness records and profile metrics are immediately and permanently erased.
B. External Server Data Retention
Echo Virtual Support does not store, retain, or maintain any personal user data, health metrics, or identity information on external company servers or cloud databases. Because all personal health records remain exclusively on the user's local device, we have zero retention of personal health data on external servers.
C. Third-Party Diagnostics & Analytics Retention
Anonymous operational telemetry collected by third-party SDKs is retained according to strict automated retention schedules:
- Firebase Crashlytics: Crash stack traces and device diagnostic logs are automatically retained by Google Firebase for 90 days, after which they are permanently expunged.
- Google Analytics for Firebase: Aggregated, anonymized event data is retained according to standard Google Analytics retention settings for up to 14 months, after which it is automatically deleted.
6. Data Deletion Policy & How to Submit a Deletion Request
In full compliance with Google Play's Data Deletion Policy and global privacy frameworks (GDPR Article 17, CCPA/CPRA), users possess the absolute right to have their data deleted. We provide two direct methods for data deletion:
Method 1: Direct On-Device Self-Service Deletion (Immediate)
Because your personal fitness data, step history, and profile metrics reside locally on your phone, you have instantaneous, direct control to wipe all data without needing developer intervention:
- Open your Android phone's Settings app.
- Select Apps (or Apps & Notifications → All Apps).
- Locate and tap Walk Tracker Pro.
- Tap Storage & Cache.
- Tap Clear Storage (or Clear Data) and confirm.
Result: This immediately and permanently deletes all SQLite database tables, daily steps, achievement streaks, personal body metrics, and preference files from your device. Alternatively, simply uninstalling the application permanently purges all local data.

7. Data Storage & Security Measures
We employ robust technical and organizational security controls to protect your information:
- Local Database Encryption: Step history and body measurements are stored within the Android sandboxed application directory using Room SQLite, accessible solely by the Walk Tracker Pro application.
- Encryption in Transit: Whenever diagnostic telemetry or purchase tokens are exchanged with Google servers, all communications are secured with Transport Layer Security (TLS 1.3 / HTTPS).
