Effective Date: November 5, 2026
Last Updated: November 5, 2026
These Terms of Service ("Terms") govern your access to and use of NBOK, including its mobile applications, desktop applications, and related services (collectively, the "Service").
By downloading, installing, or using NBOK, you agree to these Terms. If you do not agree, please do not use the Service.
1. About NBOK
NBOK is a cross-platform local area network (LAN) messenger and file transfer application that allows supported devices to communicate and exchange information over a local network.
Depending on the platform and available features, the Service may allow you to:
- Automatically discover supported devices on the same local network.
- Send and receive text messages between supported devices.
- Transfer photos, videos, documents, and other files.
- Transfer files between mobile devices and computers.
- Use drag-and-drop file transfer on supported desktop platforms.
NBOK is designed for direct communication between supported devices on a local network. It does not require a user account, login, or phone number to use its basic functionality.
2. Local Network Requirements
NBOK relies on your local network environment to discover devices and establish connections. For the Service to work properly, you may need to:
- Connect the participating devices to the same local network.
- Keep the devices powered on and connected to the network.
- Allow NBOK through your device or network firewall.
- Enable the required local network and multicast communication.
- Configure network permissions or firewall rules when necessary.
Network isolation, guest Wi-Fi restrictions, router settings, VPN configurations, firewall policies, wireless access point settings, or other network conditions may prevent devices from discovering or communicating with each other.
We do not guarantee that NBOK will work on every network, router, device, operating system, or network configuration.
3. User Responsibilities
You are responsible for how you use NBOK and for the content you send or receive through the Service.
You agree not to use NBOK to:
- Send or distribute illegal, harmful, fraudulent, or abusive content.
- Transmit malware, viruses, ransomware, or other malicious software.
- Share copyrighted or confidential material without proper authorization.
- Access devices, files, or networks without permission.
- Intercept, monitor, or interfere with another person's communications.
- Disrupt, overload, or damage networks or connected devices.
- Violate applicable laws or the rights of others.
You must ensure that you have the necessary rights and permissions before sharing files, photos, videos, or other content.
4. File Transfers and Data Integrity
NBOK provides tools for transferring files between supported devices. However, successful transfer depends on factors such as network conditions, device compatibility, available storage, file size, and operating system restrictions.
We do not guarantee that every file transfer will complete successfully, that transferred files will remain unchanged in every circumstance, or that all file formats will be supported on every device.
You are responsible for:
- Checking that files have been transferred successfully.
- Maintaining backups of important files.
- Ensuring that the receiving device has sufficient storage.
- Scanning received files when appropriate before opening them.
- Protecting sensitive information during file transfers.
5. Network Security and Privacy
NBOK is designed to communicate over a local network rather than requiring a centralized messaging account or cloud storage service for its basic LAN communication functionality.
However, a local network is not automatically secure. Other devices or users on the same network may be able to observe network activity or attempt unauthorized access, depending on the network configuration and security measures in place.
You should use trusted networks, maintain appropriate firewall and device security settings, and avoid transferring sensitive information over networks you do not trust.
We do not guarantee that all communications or transferred content will be protected against every possible security threat or unauthorized access.
6. Device Discovery and Availability
NBOK may use local network discovery mechanisms, including multicast communication, to identify supported devices.
Device discovery and connection availability may vary depending on network hardware, operating system permissions, firewall settings, device sleep states, and other technical conditions.
We do not guarantee continuous availability, uninterrupted connections, or successful communication between all supported devices.
7. Third-Party Platforms and Compatibility
NBOK may be distributed through third-party platforms such as Google Play and the Apple App Store. It may also be available for supported desktop operating systems.
Your use of those platforms and operating systems may be subject to separate terms, policies, and requirements.
We may update, modify, add, or discontinue support for particular devices, operating systems, or features. We do not guarantee compatibility with every current or future device or operating system version.
8. Intellectual Property
NBOK and its associated software, design, branding, text, graphics, and other materials are owned by or licensed to the Service operator and are protected by applicable intellectual property laws.
You may use the Service for personal and lawful purposes. These Terms do not grant you ownership of the Service or any intellectual property rights in it.
You retain the rights to content that you create or own. You are responsible for ensuring that your use and sharing of such content complies with applicable laws and third-party rights.
9. Disclaimer of Warranties
The Service is provided on an "as is" and "as available" basis, to the extent permitted by applicable law.
We make no warranties, express or implied, regarding the reliability, availability, performance, security, compatibility, or suitability of the Service.
We do not warrant that:
- Device discovery or connections will always work.
- File transfers will always complete successfully.
- Messages or files will never be lost, delayed, or corrupted.
- The Service will be uninterrupted or error-free.
- The Service will work with every network or device configuration.
10. Limitation of Liability
To the maximum extent permitted by applicable law, the Service operator shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from or related to your use of or inability to use the Service.
This includes, without limitation:
- Loss or corruption of files, photos, videos, or other data.
- Failed, interrupted, or incomplete file transfers.
- Unauthorized access to devices or local networks.
- Damage caused by malicious files or content transferred by other users.
- Network interruptions, device failures, or compatibility issues.
- Losses resulting from incorrect network or firewall configurations.
Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited under applicable law.
11. Suspension and Termination
We may suspend, restrict, modify, or discontinue all or part of the Service at any time, including where necessary for maintenance, security, legal compliance, or operational reasons.
We may restrict access if we reasonably believe that the Service is being used in violation of these Terms or in a manner that creates risks for other users, devices, or networks.
You may stop using NBOK at any time by uninstalling the application or discontinuing its use.
12. Changes to the Service and These Terms
We may update or modify NBOK, including its features, supported platforms, and technical requirements.
We may also update these Terms from time to time to reflect changes in the Service, applicable laws, or our operating practices.
The updated version will be published on this page with a revised "Last Updated" date. Your continued use of NBOK after updated Terms become effective constitutes acceptance of the revised Terms, to the extent permitted by applicable law.
13. Governing Law and Consumer Rights
These Terms shall be governed by the applicable laws relevant to the Service operator, without prejudice to any mandatory consumer protection rights that may apply in your country or region.
If any provision of these Terms is found to be unenforceable, the remaining provisions shall continue in effect to the extent permitted by applicable law.
