The terms that govern your use of 9er Systems products, software, and online services, including the USB2x adapter line, the 9er Systems Toolbar, and any related applications.

Effective date: May 20, 2026 · Last updated: May 20, 2026

Draft notice. This document is a working draft. It has not been reviewed by an attorney. Before relying on it as a binding legal agreement — especially before launching paid services or accepting customer payments — have a lawyer licensed in your jurisdiction review and adapt it. Specific terms below (governing law, dispute resolution, refund handling, aviation-specific carve-outs) should be confirmed with counsel.

1. Acceptance

These Terms of Service (“Terms”) form a binding agreement between you and 9er Systems LLC (“9er Systems,” “we,” “us,” or “our”) and govern your access to and use of our products, software, websites, and online services (collectively, the “Services”). By installing or using any of our software, creating an account, or otherwise using the Services, you agree to be bound by these Terms. If you do not agree, do not use the Services.

2. Eligibility

You must be at least eighteen (18) years old and have the legal capacity to enter into this agreement. If you are using the Services on behalf of a company or other entity, you represent that you have authority to bind that entity to these Terms.

3. The Services

9er Systems offers hardware products (including the USB2x adapter line) and associated software (including the 9er Systems Toolbar and other applications we publish). Some features require an account. Some features may, now or in the future, require a paid subscription. We may add, change, or remove features at any time without notice.

4. Accounts and Authentication

Where the Services require an account, you may register using an email address and password or by signing in through a supported third-party identity provider (such as Google, Apple, or Facebook). You agree to provide accurate information, to keep it current, and to keep your credentials confidential. You are responsible for all activity that occurs under your account. Notify us promptly at info@9ersystems.com if you suspect unauthorized use.

Where the Services allow use without a registered account (for example, a “guest” mode), you may use them without supplying personal information. We may still associate a randomly generated identifier with your installation for the purposes described in Section 9.

5. Acceptable Use

You agree not to:

  • Use the Services in any way that violates applicable law, including aviation regulations.
  • Reverse engineer, decompile, or attempt to derive source code from our software, except to the extent expressly permitted by applicable law.
  • Interfere with, disrupt, or attempt to gain unauthorized access to the Services or to any related networks or systems.
  • Use the Services to transmit malware, spam, or content that is unlawful, infringing, defamatory, or harmful.
  • Resell, sublicense, or commercially exploit the Services without our prior written consent.

6. Aviation Safety and Non-Reliance

The Services are aids only. They are not certified flight equipment, not approved navigation systems, and not a substitute for proper pilot training, judgment, or compliance with applicable regulations.

You understand and agree that:

  • Our software is not FAA-certified and is not approved for use as a primary source of flight, navigation, or safety information.
  • The pilot in command is at all times solely responsible for the safe operation of any aircraft.
  • Audio adapters and headset accessories are consumer-grade electronics. They are not intended as primary or sole communications equipment in any situation where their failure could endanger persons or property.
  • Transcriptions, callsign detection, frequency lookups, checklist content, and any other automated assistance offered by our software may be incomplete, delayed, or incorrect. You are responsible for verifying any information against authoritative sources before acting on it.

7. Intellectual Property

We retain all right, title, and interest in and to the Services, including all software, designs, documentation, trademarks, and logos. Subject to your compliance with these Terms, we grant you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to use the Services for your personal, non-commercial purposes. Nothing in these Terms transfers ownership of any intellectual property to you.

You retain ownership of any content you upload to or generate through the Services. By submitting such content, you grant us a non-exclusive, worldwide, royalty-free license to host, store, transmit, display, and process it for the purpose of providing and improving the Services.

8. Privacy

Our handling of personal data is described in our Privacy Policy (to be published). By using the Services, you consent to the collection and use of information as described there and in these Terms.

9. Usage Data and Telemetry

Our software collects usage and diagnostic information to help us understand how the Services are used, to debug problems, and to improve future versions. This information includes events such as application launches and exits, settings changes, connected device identifiers, application version, operating system name and version, and the IP address associated with the request. Where you are signed in, this information is associated with your account; where you use the Services as a guest, it is associated with a randomly generated identifier stored on your device.

Telemetry transmission is best-effort and may be silently dropped if our servers are unavailable. The continued functioning of our software does not depend on telemetry being delivered.

10. Communications and Marketing

When you provide an email address — whether by registering an account, joining a mailing list, or signing in through a third-party identity provider that shares your email with us — you agree to receive operational messages from us (such as account notifications, security alerts, and product update announcements). You also agree to receive occasional marketing communications about new products and features. You may opt out of marketing communications at any time using the unsubscribe link in those emails or by emailing info@9ersystems.com. Operational messages may continue to be sent as required for the proper operation of your account.

11. Third-Party Services

The Services may interoperate with or rely on third-party platforms (including but not limited to Google, Apple, Facebook, Amazon Web Services, Stripe, and the providers of any in-product integrations we add over time). Your use of those third-party platforms is governed by their own terms and privacy policies. We are not responsible for the availability, accuracy, or content of third-party services.

12. Purchases and Subscriptions

Hardware purchases are governed by the order confirmation we provide at the time of sale and by any limited warranty included with the product. Software subscriptions, where offered, will be billed in advance on the cycle stated at checkout and will automatically renew at the then-current rate until canceled. You may cancel a subscription at any time; cancellation takes effect at the end of the current billing period and we do not refund pro-rated unused time except where required by law.

13. Disclaimer of Warranties

THE SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not warrant that the Services will be uninterrupted, error-free, secure, accurate, or that any defects will be corrected. Some jurisdictions do not allow the exclusion of certain warranties; in such jurisdictions, our liability is limited to the maximum extent permitted by law.

14. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, 9ER SYSTEMS AND ITS OWNERS, OFFICERS, EMPLOYEES, AND AFFILIATES WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICES, REGARDLESS OF THE THEORY OF LIABILITY AND EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Our aggregate liability for any and all claims arising out of or related to these Terms or the Services will not exceed the greater of (a) the amount you paid us for the relevant Service in the twelve (12) months preceding the event giving rise to the claim, or (b) one hundred U.S. dollars ($100).

15. Indemnification

You agree to defend, indemnify, and hold harmless 9er Systems and its owners, officers, employees, and affiliates from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys’ fees) arising out of or in any way connected with: (i) your access to or use of the Services; (ii) your violation of these Terms; (iii) your violation of any applicable law or the rights of any third party; or (iv) any content you submit to or transmit through the Services.

16. Termination

We may suspend or terminate your access to the Services at any time, with or without notice, for any reason, including if we believe you have violated these Terms. You may stop using the Services at any time. Upon termination, your right to use the Services ends immediately, and Sections 7, 9, 13, 14, 15, 17, 18, and 19 will survive.

17. Changes to These Terms

We may modify these Terms at any time by posting the updated version on this page. The “Last updated” date above will reflect when the change was made. For material changes, we will make reasonable efforts to notify you by email (where we have one on file) or through an in-product notice. Your continued use of the Services after a change takes effect constitutes your acceptance of the revised Terms. If you do not agree to a change, your sole remedy is to stop using the Services.

18. Governing Law and Disputes

These Terms are governed by the laws of the State of North Carolina, United States, without regard to its conflict-of-law principles. You agree that any dispute arising out of or related to these Terms or the Services will be resolved exclusively in the state or federal courts located in Mecklenburg County, North Carolina, and you submit to the personal jurisdiction of those courts. (Confirm jurisdiction with counsel before relying on this clause; arbitration and class-action waiver provisions may be desirable but are not included in this draft.)

19. Miscellaneous

These Terms, together with any documents they expressly incorporate by reference, constitute the entire agreement between you and 9er Systems regarding the Services. If any provision is held unenforceable, the remainder of the Terms will remain in effect. Our failure to enforce a provision is not a waiver of our right to do so later. You may not assign or transfer your rights under these Terms without our prior written consent; we may assign these Terms to any successor in interest, including in connection with a merger, acquisition, or sale of assets.
