5. Nexus Shield Device Data Processing

Nexus Shield is designed with privacy as a core principle.

Network-related information processed by a Nexus Shield device is stored and processed locally on the device and is not transmitted to Nexus Shield-operated servers or services.

Depending on configuration, the device may locally process:

* Network configuration information
* DHCP lease information
* DNS request information
* Administrative settings
* System logs

Such information remains under the control of the device owner and is generally stored locally on the device.

Nexus Shield does not collect or transmit this information to Nexus Shield-operated servers.

6. Administrative Accounts

Nexus Shield devices may provide local administrative access through a web-based dashboard.

Administrative credentials, including usernames and passwords, are stored locally on the device and are not transmitted to Nexus Shield-operated servers or services.

Users are responsible for selecting strong passwords and protecting access to their devices.

7. Integrated Third-Party Components

Nexus Shield may include or integrate third-party software components that provide specific functionality.

For example, Nexus Shield may include AdGuard Home software for DNS filtering and ad-blocking capabilities.

Such components may have their own privacy documentation, licensing terms, and operational characteristics. Users are encouraged to review the documentation provided by the respective software developers.

Nexus Shield does not control the privacy practices of independent third-party services or software projects.

8. Firmware Updates

This update-related communication is separate from the device's normal network operation and is limited to checking for and delivering software updates.

To maintain security and functionality, Nexus Shield devices may periodically check whether firmware updates are available.

During update checks, our servers may receive limited technical information necessary to determine update availability, such as:

* Device IP address
* Current firmware version
* Update request metadata

This information is used solely for providing software updates, maintaining service reliability, and troubleshooting update-related issues. Update request logs, if retained, are used only for security, troubleshooting, and service reliability purposes and are not used to identify individual users.

No personally identifiable information is intentionally collected as part of update requests.

9. Analytics and Telemetry

Nexus Shield does not collect analytics, usage statistics, crash reports, or telemetry data from deployed devices.

Should optional diagnostic or telemetry features be introduced in future versions, this Privacy Policy will be updated accordingly.

10. Sharing of Information

We do not sell personal information.

We may share information only when:

* Required by applicable law
* Necessary to protect legal rights or security
* Required to provide requested services through trusted service providers acting on our behalf

Any such sharing will be limited to the minimum information necessary.

11. Data Retention

We retain personal information only for as long as necessary to fulfill the purposes described in this Privacy Policy or as required by applicable law.

Newsletter subscription information will be retained until you unsubscribe or request deletion.

Contact form submissions will be retained only for as long as reasonably necessary to respond to your inquiry, maintain relevant correspondence, or comply with applicable legal obligations.

Technical server logs may be retained for a limited period of time for security, operational, and troubleshooting purposes.

12. Data Security

We implement reasonable technical and organizational measures designed to protect personal information against unauthorized access, disclosure, alteration, or destruction.

However, no method of electronic transmission or storage can be guaranteed to be completely secure.
