License Terms for Arranger One

End User License Agreement (EULA) · As of 9 September 2026 · Version 1

These terms apply between you as the user and Hens Hensen Studio, owner Jens Lücking (address in the legal notice), hereinafter "we", for the software Arranger One in major version 1 including all related updates, documentation and license keys. By installing the software, activating a license key or using the software you accept these terms.

1. Sale and contracting parties

Licenses are sold through the payment service Stripe, which acts as merchant of record (shown as "Link" at checkout) and is the seller towards you. Payment processing, invoicing, taxes, withdrawal and refunds are governed by the terms of Stripe / Link. The use of the software itself is governed exclusively by this agreement.

2. Scope of the license

  1. We grant you a simple, non-exclusive, perpetual right to install and use Arranger One on up to three Macs that you use yourself. Private and professional use is permitted, in particular for producing your own music, audio and video works, which you may exploit without restriction.
  2. The free trial may be used without a license key for an unlimited time; it is limited in functionality (no mixdown and no export).
  3. A license key is personal. It may not be published, passed on, rented, lent or sold. The license may be transferred to another person with our prior consent in text form; it then expires for you.
  4. The license includes all updates of major version 1. A new major version (for example version 2) is a separate product and may be offered at an upgrade price.

3. License verification

On start-up the software verifies the license key online against our license server, transmitting the key, the program version and a device identifier (the Mac's serial number) to limit the number of activated devices. Without an internet connection an activated license remains valid for at least 14 days. Devices can be released in the software's settings or on request. Details on data processing are in the privacy policy (German).

4. Restrictions

You may not decompile, disassemble or otherwise reverse engineer the software except where mandatory law permits, you may not circumvent the license or copy protection, and you may not use the software to infringe the rights of third parties or applicable law. The software or parts of it may not be redistributed as a stand-alone product.

5. Third-party plugins, sounds and components

Arranger One ships without instruments, effect plugins and sample libraries. Plugins and content you use within the software are subject to the license terms of their respective vendors; you are responsible for their function, availability and lawful use. The software contains open-source components; the related license notices are available in the software. Integrations with third-party services (such as hardware controllers or online services) depend on their availability and may change.

6. AI-assisted features

Some features (such as stem separation, vocal and choir tools or music generation) work with models installed locally on your Mac. Their results are generated automatically; we do not warrant their quality, suitability or freedom from third-party rights. You are responsible for holding the necessary rights to audio material you process with these features and for using the results lawfully. The models may be subject to their own license terms shown during installation.

7. Warranty

Statutory warranty rights apply. We warrant that, when used as intended on the systems named in the product description, the software functions substantially as described. We do not warrant fitness for your particular purpose, uninterrupted or error-free operation, or interoperability with specific third-party plugins or devices. Features marked as preview or beta are provided without warranty.

8. Liability

  1. We are liable without limitation for intent and gross negligence, for injury to life, body or health, under the German Product Liability Act, and to the extent of any guarantee we have given.
  2. In cases of slight negligence we are liable only for breach of a material contractual obligation, i.e. an obligation whose fulfilment is essential for the proper performance of the contract and on whose observance you may regularly rely. In that case liability is limited to the foreseeable damage typical for this kind of contract.
  3. Any further liability is excluded. This applies in particular to indirect damage, lost profit and loss of data to the extent it could have been avoided by regular, state-of-the-art backups. Audio productions are data: back up your projects regularly.
  4. The above limitations also apply to the personal liability of our employees and agents.

9. Term and termination

The license is perpetual. In the event of a material breach of these terms, in particular passing on license keys or circumventing the license protection, we may terminate the license after an unsuccessful warning and block the key. You must then stop using the software.

10. Withdrawal and refunds

The seller is Stripe (Link). Questions about withdrawal, returns and refunds are governed by Link's terms; Link support can be reached via your receipt. For problems with the software itself we are happy to help via the contact form.

11. Final provisions

The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, the mandatory consumer protection provisions of your country of residence remain unaffected. Should individual provisions be invalid, the remainder of the agreement remains in force. Changes to these terms apply to licenses purchased after publication of the amended version. In case of discrepancies between the German and the English version, the German version prevails.
