End User License Agreement

Last updated: April 11, 2026

This End User License Agreement, or EULA, is a legal agreement between you and SemSwitch, Inc. ("Licensor," "we," "us," or "our") governing your installation, access to, and use of the soundOS desktop software, including the current Windows desktop application, installer, updates, related documentation, and associated software components we provide with or for soundOS (collectively, the "Software").

By clicking I Agree, installing the Software, accessing it, or using it, you agree to this EULA. If you do not agree, do not install, access, or use the Software.

1. License grant

Subject to your compliance with this EULA and any applicable subscription, entitlement, or fee requirements, Licensor grants you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to install and use the Software on devices you own or control, solely for your internal personal or business use.

This license is granted, not sold.

2. Eligibility and account requirements

Certain features of the Software may require:

  • an internet connection
  • a soundOS account
  • verification of account or subscription status
  • acceptance of separate service, privacy, billing, or feature-specific terms

You are responsible for maintaining the confidentiality of your account credentials and for all activity occurring through your use of the Software.

3. Trials, paid access, and online features

The Software may include free, trial, beta, limited, or subscription-gated features.

Access to certain cloud-connected, orchestration, terminal, voice, artifact, automation, collaboration, or AI-enabled features may require an active trial, paid subscription, or separate entitlement under our then-current billing terms or purchase flow.

If your trial expires, your subscription lapses, your payment fails, or your account is suspended or terminated, some or all online or premium features may be limited, disabled, or unavailable.

We may modify, suspend, or discontinue features, integrations, or service components at any time.

4. Updates

The Software may download or apply updates, patches, compatibility changes, configuration changes, feature changes, or model/provider changes automatically or upon notice.

Those updates are part of the Software and are governed by this EULA unless separate terms accompany the update.

We are not obligated to provide any particular update, maintenance schedule, support level, or continued feature availability.

5. Local execution, provider keys, and machine responsibility

soundOS is not only a passive viewer. The Software includes local desktop runtime behavior.

Depending on the feature, soundOS may:

  • launch local terminal sessions or local processes on devices you control
  • interact with local repositories, shells, or tools you choose to expose to it
  • open browser-based sign-in and local callback flows during authentication
  • store non-secret profile and cache data in operating-system-managed app data directories
  • store provider API keys and certain refresh/session material in the operating system credential manager or keychain

You are responsible for the devices, files, repositories, prompts, commands, environments, provider accounts, and execution contexts you connect to the Software.

If you enter third-party provider API keys into the Software, you authorize soundOS to use those keys to call the selected provider on your behalf for the features you invoke.

6. User content and outputs

You may submit prompts, commands, audio, text, files, configurations, workflows, and other materials through the Software ("User Content").

As between you and Licensor, and subject to your compliance with this EULA and applicable law, you retain your rights in your User Content.

As between you and Licensor, and subject to applicable law and any third-party provider terms, you also retain your rights, if any, in outputs, code, text, transcripts, reports, artifacts, workflows, and other materials generated for you through your authorized use of the Software ("Outputs").

You represent and warrant that you have all rights necessary to provide your User Content and to use the Software in connection with that User Content.

7. Ownership

The Software, including its code, structure, design, interface elements, documentation, proprietary workflows, transport and orchestration architecture, backend services, and all related intellectual property rights, is and will remain the exclusive property of Licensor and its licensors.

No ownership rights in the Software are transferred to you.

Except for the limited license expressly granted in this EULA, Licensor reserves all rights.

8. Restrictions

You may not, and may not permit any third party to:

  • copy, reproduce, distribute, sell, lease, sublicense, assign, transfer, publish, or make the Software available to third parties except as expressly permitted by this EULA
  • reverse engineer, decompile, disassemble, decode, adapt, or otherwise attempt to derive source code, trade secrets, non-public APIs, protocols, or architecture from the Software except to the extent such restriction is prohibited by applicable law
  • bypass, disable, defeat, or interfere with licensing checks, subscriptions, access controls, rate limits, integrity checks, security features, usage restrictions, or technical enforcement mechanisms
  • use the Software to build, validate, benchmark, train, or improve a competing product or service using non-public behavior, access, or interfaces of the Software
  • remove, alter, or obscure copyright, trademark, proprietary rights, or attribution notices
  • use the Software in violation of law, regulation, third-party rights, or this EULA
  • use the Software to transmit malware, abuse infrastructure, interfere with networks, or compromise the security or integrity of any system or user
  • use the Software on systems, data, or accounts you are not authorized to access or control
  • use the Software in any manner not expressly authorized by this EULA

9. Third-party services and components

The Software may interoperate with or depend on third-party services, models, APIs, hosting providers, speech services, communications providers, package ecosystems, or open-source components.

Your use of third-party services may be subject to separate third-party terms, policies, and availability. Licensor is not responsible for third-party services and does not guarantee that any third-party service or integration will remain available, compatible, or unchanged.

Any open-source components included with the Software are licensed under their applicable open-source licenses. If there is a conflict between this EULA and an applicable open-source license as to that component, the open-source license controls for that component.

10. Privacy and data handling

Your use of the Software is also subject to the soundOS Privacy Policy at https://soundos.app/privacy.

You acknowledge that certain features of the Software require the processing, transmission, storage, or retention of User Content, device data, account data, session data, transcript or artifact data, provider-routing data, diagnostic data, and usage data in order to operate, secure, support, and maintain the Software and related services.

11. Feedback

If you provide suggestions, ideas, enhancement requests, corrections, or other feedback regarding the Software ("Feedback"), you grant Licensor a worldwide, perpetual, irrevocable, non-exclusive, royalty-free right to use, copy, modify, incorporate, commercialize, and otherwise exploit that Feedback without restriction or compensation to you.

12. Suspension and termination

This EULA begins when you first accept it, install the Software, access it, or use it, and continues until terminated.

Licensor may suspend or terminate this EULA, your license, your account, or your access to some or all of the Software immediately if:

  • you breach this EULA
  • you fail to maintain a required subscription or entitlement
  • your use creates legal, security, abuse, or operational risk
  • Licensor is required to do so by law or by a provider requirement

Upon termination, the license granted to you ends immediately and you must stop using the Software.

Sections that by their nature should survive termination will survive, including Sections 6 through 18.

13. Disclaimer of warranties

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, LICENSOR DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, QUIET ENJOYMENT, ACCURACY, AVAILABILITY, OR THAT THE SOFTWARE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR MEET YOUR REQUIREMENTS.

WITHOUT LIMITING THE FOREGOING, LICENSOR DOES NOT WARRANT THAT OUTPUTS, TRANSCRIPTS, RECEIPTS, AUTOMATIONS, APPROVALS, OR AI-ENABLED FEATURES WILL BE COMPLETE, ACCURATE, RELIABLE, OR FIT FOR ANY PARTICULAR USE.

14. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, LICENSOR AND ITS AFFILIATES, LICENSORS, SERVICE PROVIDERS, AND SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, GOODWILL, DATA, BUSINESS OPPORTUNITY, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO THE SOFTWARE OR THIS EULA, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE TOTAL AGGREGATE LIABILITY OF LICENSOR FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SOFTWARE OR THIS EULA WILL NOT EXCEED THE GREATER OF:

  • (A) THE AMOUNT YOU PAID TO LICENSOR FOR THE SOFTWARE OR RELATED SUBSCRIPTION DURING THE THREE (3) MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM; OR
  • (B) USD $100

15. Governing law and venue

This EULA is governed by the laws of the State of Texas, without regard to its conflict of laws principles.

Any dispute, claim, or controversy arising out of or relating to this EULA or the Software shall be brought exclusively in the state courts located in Denton County, Texas, or the United States District Court for the Eastern District of Texas, and each party consents to the personal jurisdiction and venue of those courts.

16. Changes to this EULA

Licensor may update this EULA from time to time.

If required by applicable law, Licensor will provide notice of material changes. Your continued use of the Software after the effective date of an updated EULA constitutes your acceptance of the updated EULA, except where applicable law requires a different form of consent.

17. General

This EULA constitutes the entire agreement between you and Licensor regarding the Software and supersedes prior or contemporaneous understandings relating to the Software, except for any separate written agreement you have with us that expressly overrides it.

If any provision of this EULA is held unenforceable, the remaining provisions will remain in full force and effect.

Licensor's failure to enforce any provision of this EULA is not a waiver of that provision.

You may not assign or transfer this EULA without Licensor's prior written consent. Licensor may assign this EULA in connection with a merger, acquisition, corporate reorganization, or sale of assets.
