Privacy Policy for NetBlock Shield – App Blocker

Effective Date: September 19, 2026

NetGram IT Solutions LLP ("we," "us," or "our") develops and maintains NetBlock Shield – App Blocker. This Privacy Policy outlines our strict adherence to user privacy, data minimization, and Google Play policies regarding the operation of our local firewall application.

1. The Android VpnService and Your Privacy

NetBlock Shield relies on the Android VpnService API to function as an on-device firewall. To comply with Google Play Developer Policies, we explicitly declare the following regarding our use of this service:

• Local Operation Only: The VPN interface created by NetBlock Shield is entirely local (a loopback interface). It does not connect to any external, remote, or third-party VPN servers.
• No Traffic Redirection: Your internet traffic is never tunneled, routed, or forwarded to our servers or any outside entity.
• No Payload Inspection: We do not monitor, inspect, log, or record the contents of your web traffic, DNS requests, or application data payloads. The app simply drops network packets for apps you have explicitly blocked.
• No Data Monetization: Because we do not collect your network data, we do not—and cannot—sell or share your traffic data with third parties.

2. Information We Do Not Collect

NetBlock Shield operates on a "zero-knowledge" architecture. We do not require, collect, or store:

• Personal Identifiable Information (Names, email addresses, phone numbers).
• Account creation credentials.
• Location data (GPS or IP-based).
• Browsing history or app usage telemetry.

3. Local Device Permissions and Data Processing

To provide core functionality, the app requests specific on-device permissions. The data accessed via these permissions never leaves your device:

• `QUERY_ALL_PACKAGES` (App Inventory): NetBlock Shield requires this permission to retrieve a list of installed applications on your device. This allows you to select which specific apps to block or allow. This app list is processed strictly in your device's local memory and is never transmitted online.
• Local Storage: Your firewall rules (which apps are blocked), application settings, and security PINs are stored securely in local encrypted preferences on your device.

4. Third-Party Analytics and Crash Reporting

We may utilize standard, privacy-compliant developer tools (such as Google Play Core or Firebase Crashlytics) exclusively to monitor application stability.

• If the app crashes, anonymous diagnostic data (such as device model, Android OS version, and crash stack traces) may be logged.
• This diagnostic data contains no personal information and cannot be linked to your local firewall rules or identity.

5. Children's Privacy

NetBlock Shield does not target children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us so we can take steps to remove it.

6. User Control and Data Deletion

Because all your data is stored locally, you maintain absolute control over it. You can instantly delete all data, rules, and PINs associated with NetBlock Shield by:

1. Navigating to your device's Settings > Apps > NetBlock Shield.
2. Selecting Storage & cache.
3. Tapping Clear storage (or Clear data).

Uninstalling the application will also permanently remove all associated local data and configurations.

7. Policy Updates

We may update this Privacy Policy from time to time to reflect new app features or policy requirements. The most current version will always be hosted on our official website, and we encourage you to review it periodically.
