JackMoebius — End-User License Agreement
Effective date: 10 July 2026 Licensor: Éric Bavu, France (“Licensor”) Support: https://github.com/zinc75/JackMoebius/discussions Software: JackMoebius — the product name used to identify the Software — is a macOS CoreAudio↔︎JACK bridge comprising the AudioServerPlugIn driver (JackMoebius.driver), the jackmoebiusd daemon, the jackmoebius CLI, their installer, documentation, and any updates (the “Software”).
This JackMoebius (“Software”) End-User License Agreement (“EULA” or “Agreement”) is a legal agreement between you (either an individual or, if obtained for an entity, that entity) and the licensor. READ IT CAREFULLY BEFORE COMPLETING THE INSTALLATION PROCESS AND USING THIS SOFTWARE. It provides a license to use this Software and contains warranty and liability disclaimers.
BY DOWNLOADING OR INSTALLING THE SOFTWARE YOU ARE INDICATING YOUR FULL AND VOLUNTARY ASSENT TO THE TERMS OF THIS AGREEMENT.
If you do not agree to all of the following terms, do not download or install the Software, or discontinue use immediately and delete all copies on your computer.
1. Acceptance
By downloading, installing, copying or using the Software you (“you”) agree to this Agreement. If you do not agree, do not download or install the Software, or discontinue use immediately and delete all copies.
2. License grant
Subject to your compliance with this Agreement and payment of the applicable fee after the trial, the Licensor grants you a personal, non-exclusive, non-transferable, non-sublicensable, worldwide license to install and use the Software, for your own use, on macOS computers that you personally own or use, up to the number of simultaneous device activations permitted by your license (its “activation limit,” as shown at the time of purchase). You may deactivate a device to free an activation and activate another device in its place, provided that the number of simultaneously activated devices never exceeds your activation limit. Each license covers one individual user.
This is a license, not a sale of the Software (see Section 7).
3. Trial period
The Software is offered with a fully functional, free evaluation period of 14 days from first use (“Trial Period”). During the Trial Period the Licensor grants you a limited, non-exclusive, non-transferable license to use the Software for evaluation purposes. Please evaluate it carefully during this period. During evaluation the Software is provided on the same “AS IS” basis as set out below. At the end of the Trial Period, continued use requires the purchase of a license.
4. Installation and system components
The Software may install system-level components, including audio drivers and background services, which may require administrative privileges on your computer.
By installing the Software, you authorize the installation and operation of these components.
You are responsible for ensuring that you have the necessary permissions to install and use the Software on your computer.
5. License after the trial; fee
If you continue to use the Software after the Trial Period, a license must be purchased. The applicable license fee is the amount displayed at the time of purchase. To purchase, visit https://zinc75.github.io/JackMoebius/#buy. For private matters related to purchases, payments or personal information, please use the private support channel provided by the licensing platform during the purchase process.
6. Versions and updates
Your purchased license applies to the current version of the Software and includes updates and improvements provided by the Licensor for that version.
The Licensor may offer separate licenses or upgrades for future major versions of the Software.
The license terms applicable to future major versions may differ from those of the current version.
7. Ownership
The Software is licensed, not sold. The Licensor and applicable third-party rights holders retain all right, title and interest in and to the Software, including all intellectual-property rights and the structure, organization and code of the Software (valuable trade secrets). No rights are granted except as expressly stated here.
8. Restrictions
Except to the extent applicable law expressly permits notwithstanding this clause, you may not: (a) sell, rent, lease, lend, sublicense, transfer, resell or otherwise redistribute the Software, its documentation or any part thereof; (b) reverse engineer, decompile or disassemble the Software, except for interoperability to the extent permitted by Directive 2009/24/EC and applicable law; (c) modify, translate, adapt or create derivative works of the Software — however, you may develop, distribute and use software that interoperates with the Software through its documented inter-process (IPC) interface (e.g. patchbay or control applications), provided you comply with the rest of this Agreement; (d) remove, alter or obscure any copyright, proprietary or third-party notices, or any license-enforcement mechanism; (e) use the Software to build a competing product.
9. Third-party components
The Software incorporates or interoperates with third-party components under their own licenses, which continue to apply and prevail over this Agreement to the extent of any conflict (full texts in the Third-Party Notices appendix at the end of this Agreement): - portions of the Software based on or inspired by prism and spectrum (© petitstrawberry), used under the MIT License; - neither the JACK client library (libjack, GNU LGPL) nor the JACK server (GNU GPL) is distributed with the Software: libjack is loaded dynamically at runtime from your own JACK installation, and the server is separate software you install and run yourself. Nothing here limits your rights in those components under their respective licenses.
The installer can optionally install JackMate, a separate companion application by the same author, provided free of charge under the MIT License. JackMate is not part of the Software licensed under this Agreement and is not covered by it; your use of JackMate is governed solely by its own MIT License (reproduced in the appendix). Installing it is optional and can be declined in the installer.
10. Updates and support
The Licensor may, but is not obliged to, provide updates, which are governed by this Agreement unless delivered with a separate license. Support, if provided, is available through the JackMoebius support channels.
11. Consumer rights
If you are a consumer, you retain all mandatory statutory rights under the law applicable to your country of residence, including applicable legal guarantees and withdrawal rights.
Nothing in this Agreement limits or excludes any consumer right that cannot legally be limited or excluded.
12. Disclaimer
To the maximum extent permitted by applicable law, and without limiting Section 11, the Software is provided “AS IS” and “AS AVAILABLE”, with all faults and without warranties of any kind, whether express, implied or statutory, including merchantability, fitness for a particular purpose and non-infringement. The Licensor does not warrant that the Software will be uninterrupted or error-free. Should the Software prove defective, you assume the cost of all necessary servicing, repair or correction. Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you.
13. Audio safety
The Software routes and processes audio and can produce unexpected or loud output (e.g. feedback loops or misconfiguration). You are responsible for protecting your hearing and your equipment (monitor levels, limiters, speaker protection). To the extent permitted by law, the Licensor is not liable for damage resulting from such output.
14. Limitation of liability
To the maximum extent permitted by applicable law, the Licensor will not be liable for any indirect, incidental, special, consequential or punitive damages, or for loss of data, audio, profits or goodwill, arising out of or relating to the Software or the provision of (or failure to provide) support. The Licensor’s total aggregate liability will not exceed the amount you paid for the Software. Some jurisdictions do not allow the exclusion of consequential damages, so parts of this section may not apply to you. Nothing excludes liability that cannot be excluded by law (e.g. death or personal injury caused by negligence, or fraud). This section states the Licensor’s entire liability and your exclusive remedy regarding the Software.
15. Refunds and purchases
Sales are processed by Lemon Squeezy as merchant of record for the transaction.
Purchases, payments, taxes, invoices, refunds and any applicable withdrawal rights are handled according to Lemon Squeezy’s terms and policies and applicable consumer law.
The Software includes a fully functional 14-day evaluation period, allowing users to evaluate the Software before purchase. The existence of this evaluation period does not affect any mandatory consumer rights.
16. Termination
This Agreement applies until terminated. It terminates automatically if you fail to comply with any term or condition. On termination you must stop using and delete all copies of the Software. Sections 7 to 9 and 12 to 19 survive termination.
17. Governing law
This Agreement is governed by the laws of France, without regard to conflict-of-laws rules. The competent courts of France have jurisdiction — except that, if you are a consumer, you may also rely on the mandatory provisions and the courts of your country of residence.
18. Acceptable use
The Software is a general-purpose audio-routing tool. You are solely responsible for your use of it and for ensuring that your use complies with all applicable laws and the rights of third parties. In particular, you must not use the Software to infringe copyright or other intellectual-property rights, to circumvent any technological protection measure, or in violation of the terms of any third-party service. The Licensor does not endorse, and assumes no responsibility for, any unlawful use of the Software.
19. General
You may not assign this Agreement; any attempt to do so is void. This is the entire agreement regarding the Software and supersedes prior understandings about it. If a provision is unenforceable, it is modified to the minimum extent necessary to make it enforceable, and the rest remains in effect. Failure to enforce a provision is not a waiver of it.
