Privacy Policy for Nari

Effective Date: March 26, 2026

Thank you for choosing to use Nari. We understand that your privacy is important. This Privacy Policy outlines our practices regarding the collection, use, and disclosure of your information when you use our mobile application ("App").

1. Data Collection and Usage

We do not collect, transmit, store, or share any of your Personal or Sensitive User Data.

Nari operates 100% offline and locally on your device. All calculations, tracking metrics, and application states are processed within the isolated environment of your smartphone. We do not use any remote servers, cloud databases, or third-party analytics trackers to monitor your activity.

2. Required Permissions and Clear Justification

To provide its core functionality (preventing "dumbscrolling" and limiting excessive screen time), Nari requires specific Android system permissions. Below is a detailed explanation of why each permission is absolutely necessary and how it is used strictly within the boundaries of the law and Google Play Developer Policies:

a) Usage Access (PACKAGE_USAGE_STATS)

• Why we need it: To determine which applications are currently active on your screen and calculate the duration of your usage.
• How it is used: Nari checks the foreground application name against your personal "monitored apps" list. If a match is found, a local timer starts.
• Privacy Guarantee: We solely use this permission for local time-tracking. We do not record your interaction history, keystrokes, content viewed inside those apps, or transmit this usage data to any external server.

b) Display Over Other Apps (SYSTEM_ALERT_WINDOW)

• Why we need it: To instantly display a warning overlay popup (Nari's intervention screen) when your usage limit is exceeded.
• How it is used: When the local timer hits the configured limit (e.g., 5 minutes), Nari draws a full-screen block over the monitored app to interrupt your scrolling habit.
• Privacy Guarantee: This permission is strictly utilized to render our UI components over the active screen. It is not used for clickjacking, ad-injection, or any malicious UI interference.

c) Foreground Service & Notifications (FOREGROUND_SERVICE & POST_NOTIFICATIONS)

• Why we need it: Android OS requires background tracking applications to declare a visible Foreground Service to ensure transparency to the user.
• How it is used: Nari runs a continuous local service to keep the timer accurate even when the app is closed. This service displays a persistent, low-priority notification in your status bar so you are always aware that Nari is active.

d) Run at Startup (RECEIVE_BOOT_COMPLETED)

• Why we need it: To ensure your Nari protections automatically resume after you restart your phone, without requiring you to manually open the app again.

e) Background Activity / Battery Optimization Exemption (REQUEST_IGNORE_BATTERY_OPTIMIZATIONS)

• Why we need it: On certain Android manufacturers (notably Samsung One UI and Xiaomi MIUI/HyperOS), the operating system aggressively kills background processes — including Foreground Services — when the user swipes an app from the Recent Apps screen, overriding Android's standard stopWithTask="false" declaration. Requesting a battery optimization exemption instructs the OS to treat Nari as a high-priority process and allow it to self-restart without user intervention.
• How it is used: If granted, this permission solely prevents Nari's monitoring service from being terminated by manufacturer-specific battery management systems. It does not grant Nari access to any personal data, network resources, or device sensors beyond what is already declared above.
• This permission is optional. Nari's core functionality remains fully operational without it. Users on stock Android (Pixel and other AOSP-based devices) are unaffected. However, on Samsung and Xiaomi devices, denying this permission may cause the monitoring service to stop temporarily after the app is removed from Recent Apps, until the periodic AlarmManager keepalive restarts it (typically within 5 seconds).
• Privacy Guarantee: This exemption does not allow Nari to collect additional data, run network requests, or perform any action outside of its stated screen-time monitoring purpose.

3. Data Storage and Security

All of your preferences (such as the list of monitored apps, time limits, and Action History) are saved securely in your device's local storage (SQLite/Room Database and SharedPreferences) and are exclusively accessible by Nari. If you uninstall the App, all associated tracking data is permanently deleted from your device.

4. Children's Privacy

Our App does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13. Given our strict "Zero Data Collection" architecture, no child's data can ever be transmitted or compromised.

5. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Effective Date" at the top. You are advised to review this Privacy Policy periodically for any changes.
