Terms of Use & End User License Agreement

Effective date: 22 June 2026

In plain terms: You may use Composa to make songs, and you own what you create — including for commercial use. In exchange, you agree to use the app responsibly and lawfully, you accept that AI output is not guaranteed to be unique or perfect, and you accept that the app is provided “as is.”

These Terms of Use and End User License Agreement (the “Terms”) are a legal agreement between you (“you” or “the user”) and the developer of Composa (“Composa,” “we,” “us,” or “our”) governing your use of the Composa macOS application and any accompanying components and updates (collectively, the “App”). By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree, do not use the App.

1. License grant

Subject to your compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to download and use one copy of the App on Apple-branded devices that you own or control, as permitted by the Apple Media Services Terms and the Usage Rules in the App Store Terms of Service. This is a license, not a sale; we and our licensors retain all right, title, and interest in and to the App itself (excluding the content you generate, which is addressed in Section 3).

2. Restrictions

Except to the extent this restriction is prohibited by applicable law or permitted by the license of an open-source component, you agree not to:

copy, distribute, rent, lease, lend, sell, or sublicense the App;
reverse engineer, decompile, or disassemble the App, or attempt to derive its source code;
modify, adapt, or create derivative works of the App;
remove or alter any proprietary notices or labels on the App;
use the App in any way that violates these Terms or applicable law.

3. Your content — you own what you create

You own the songs, music, lyrics, and vocals you generate with the App (“Output”), to the maximum extent permitted by applicable law, and you may use the Output for any lawful purpose, including commercial purposes. We claim no ownership of your Output, do not collect it, and do not receive copies of it — generation happens entirely on your device.

However, you acknowledge and agree that:

No guarantee of uniqueness or originality. AI generation is probabilistic. We do not and cannot guarantee that any Output is unique, original, or free of similarity to existing works, names, melodies, or recordings. Different users may generate similar or identical Output from similar inputs.
You are responsible for your inputs and your Output. You are solely responsible for the prompts, lyrics, style descriptions, and other inputs you provide, and for how you use, publish, distribute, or monetize the Output. You are responsible for ensuring that your inputs and your use of the Output do not infringe the intellectual property, publicity, privacy, or other rights of any third party, and comply with all applicable laws.
No legal advice or clearance. We do not provide legal advice, rights clearance, or licensing for any Output. Before commercial use, you should make your own assessment and, where appropriate, seek independent legal advice.

4. Acceptable use

You agree not to use the App, and not to use any Output, to create, generate, or distribute material that:

infringes the copyright, trademark, publicity, or other rights of any person or entity;
is unlawful, defamatory, harassing, hateful, or that incites violence or discrimination;
is sexual content involving minors, or that sexualizes, exploits, or endangers minors in any way (strictly prohibited);
impersonates a real person or a recognizable artist’s voice or identity without authorization;
is otherwise illegal or that you are not authorized to create.

To support responsible use, the App applies on-device filtering to prompts and may decline to generate certain requests. We reserve the right to suspend or terminate your license and access to the App if you violate this Section 4 or otherwise misuse the App.

5. AI output disclaimer

The App uses artificial intelligence to generate music, lyrics, and vocals. AI output can be inaccurate, imperfect, repetitive, nonsensical, or otherwise not what you intended, and may occasionally produce content that is offensive or unexpected. The App is a creative tool, and the Output should be reviewed and edited by you before any reliance or publication. We make no representation that the Output will meet your requirements or be suitable for any particular purpose.

6. Third-party and open-source components

The App incorporates third-party and open-source software, which is licensed to you under the terms of its respective licenses. These include, without limitation:

ACE-Step (music generation model) — MIT License;
MLX (Apple machine-learning framework) — MIT License;
Apple FoundationModels / Apple Intelligence (on-device lyric generation, where available) — subject to Apple’s applicable software license terms.

To the extent any open-source license conflicts with these Terms with respect to the corresponding component, the open-source license governs that component. The App downloads AI model weights as needed but the App Store listing and the App itself do not redistribute model weights. Acknowledgement of these components does not imply any endorsement of the App by their authors.

7. Updates

We may provide updates, upgrades, or modifications to the App from time to time. These Terms govern any such updates unless they are accompanied by separate terms, in which case those separate terms apply.

8. Disclaimer of warranties

THE APP AND ALL OUTPUT ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT ANY OUTPUT WILL BE ACCURATE, UNIQUE, ORIGINAL, OR NON-INFRINGING. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU.

9. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL WE 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 RELATING TO YOUR USE OF (OR INABILITY TO USE) THE APP OR THE OUTPUT, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE APP WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID FOR THE APP IN THE TWELVE MONTHS PRECEDING THE CLAIM, OR (B) USD $50. SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OR EXCLUSION OF LIABILITY FOR CERTAIN DAMAGES, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

10. Indemnification

To the extent permitted by applicable law, you agree to indemnify and hold us harmless from any claims, damages, liabilities, and expenses (including reasonable legal fees) arising out of your inputs, your Output, your use of the App, or your violation of these Terms or of any applicable law or third-party right.

11. Termination

These Terms apply until terminated. Your license terminates automatically if you breach these Terms. Upon termination, you must stop using the App and delete all copies. Sections that by their nature should survive termination (including Sections 3, 5, 8, 9, 10, and 13) will survive.

12. Apple as third-party beneficiary

These Terms are between you and us only, and not with Apple Inc. (“Apple”). Apple is not responsible for the App or its content. You acknowledge that:

Apple has no obligation to furnish any maintenance or support services for the App;
in the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the App; to the maximum extent permitted by law, Apple will have no other warranty obligation with respect to the App;
Apple is not responsible for addressing any claims by you or any third party relating to the App or your possession and use of it, including product liability claims, claims that the App fails to conform to any legal or regulatory requirement, and claims arising under consumer protection or similar legislation;
in the event of any third-party claim that the App or your possession and use of it infringes that third party’s intellectual property rights, we, not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of any such claim to the extent required by these Terms;
you represent that you are not located in a country subject to a U.S. Government embargo or designated as “terrorist supporting,” and that you are not on any U.S. Government list of prohibited or restricted parties;
Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

13. Governing law

These Terms are governed by the laws of [insert governing jurisdiction], without regard to its conflict-of-laws principles, except that this choice of law does not deprive you of any mandatory consumer protections of the jurisdiction in which you reside. Any disputes will be subject to the exclusive jurisdiction of the courts of [insert venue], subject to those mandatory consumer protections. (Placeholder — complete before submission.)

14. Changes to these Terms

We may update these Terms from time to time. When we do, we will revise the “Effective date” above and post the updated Terms here. Material changes will be reflected in a clearly dated version. Your continued use of the App after an update means you accept the revised Terms.

15. Miscellaneous

If any provision of these Terms is held unenforceable, the remaining provisions will remain in full force. Our failure to enforce any provision is not a waiver of it. These Terms, together with the Apple Media Services Terms and our Privacy Policy, constitute the entire agreement between you and us regarding the App.
