End User License Agreement

StemMaster — last updated 10 July 2026
Plain-English summary (the full terms below govern): you buy StemMaster once and it's yours — use it on up to 3 of your machines, for personal or commercial music, forever. Everything you export is 100% yours, no royalties. Free updates for all 1.x versions. 14-day money-back guarantee. Don't resell the app or your license key.

This End User License Agreement ("Agreement") is between you and NOMZ Studios, Dubai, United Arab Emirates ("we", "us"), and governs your use of the StemMaster desktop application, in both its full and demo editions (the "Software"). By installing or using the Software you agree to this Agreement.

1. License grant

Upon purchase, we grant you a personal, non-exclusive, non-transferable, perpetual license to install and use the Software on up to three (3) devices that you own or control, for personal or commercial purposes. The license is per person, not per company: each additional user needs their own license.

2. Demo edition

The demo edition is free for evaluation. It is the full Software with audio export disabled. You may use it for as long as you like and share the unmodified demo installer, but you may not attempt to enable export functionality or otherwise circumvent the demo limitations.

3. Your audio and output

Everything you create with the Software — mixes, masters, exported audio — is entirely yours. We claim no ownership of and no royalties on your work, whether personal or commercial. The Software processes your audio locally on your machine; see the Privacy Policy.

4. Restrictions

5. Third-party components

The Software bundles open-source components (including Qt/PySide6, libsndfile and LAME under the LGPL) as separate, replaceable dynamic libraries. Their licenses are included with the Software in THIRD-PARTY-LICENSES.txt and are not limited by this Agreement.

6. Updates

Your license includes all 1.x updates free of charge. Future major versions (2.0 and beyond) may be a separate, optional purchase — your licensed version keeps working either way. The Software may check a small version file on our website at startup to tell you when an update exists; it downloads nothing without your action.

7. Refunds

If StemMaster isn't for you, contact info@nomzstudios.com within 14 days of purchase for a full refund.

8. Warranty disclaimer

The Software is provided "as is", without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. Audio processing results are subjective; we do not warrant that the Software will meet your artistic expectations.

9. Limitation of liability

To the maximum extent permitted by law, our total liability arising out of or related to this Agreement is limited to the amount you paid for the Software. We are not liable for indirect, incidental, or consequential damages, including loss of data or audio projects — please keep backups of your session files and stems.

10. Termination

This Agreement terminates automatically if you materially breach it. Upon termination you must stop using the Software and delete your copies. Sections 3, 8, 9 and 11 survive termination.

11. Governing law

This Agreement is governed by the laws of the Emirate of Dubai and the applicable federal laws of the United Arab Emirates. Nothing in this Agreement limits any non-waivable consumer rights you have under the laws of your country of residence.
