End User License Agreement & Terms of Service

The arrangementLab web application, including all features, tools, templates, and services provided through the platform.

The individual or entity accessing, creating an account for, or using the Software.

arrangementLab and its parent companies, subsidiaries, and affiliates.

All arrangements, song structures, notes, lyrics, and other creative materials created, uploaded, or otherwise generated using the Software.

The artificial intelligence-powered tools within the Software, including the AI suggestion engine, Smart Suggestions feature, and any other AI-assisted capabilities.

arrangementLab does not require you to create an account or maintain a password. You use the Software directly in your web browser, and your projects are stored locally on your device (in your browser's local storage). After purchase, you receive a license key by email that unlocks full access on the devices you use.

arrangementLab is sold as a one-time purchase, not a subscription. A single payment grants you a perpetual license to use the Software as described in Section 4. There are no subscription plans, billing cycles, or recurring charges.

Your one-time purchase includes access to the version of the Software you purchased and to updates we release for it, for as long as we offer the product. Your license to the version you purchased does not expire. We are not obligated to provide updates indefinitely or to operate the Software in perpetuity, but we will not revoke a validly purchased license.

The purchase price is shown on our website at the time of purchase. We may change the price for future purchasers — for example, when launch pricing ends — but a price change never affects a purchase you have already made. You are charged once, at the price shown when you buy.

We offer a 14-day free trial that does not require a credit card or any payment information. The trial lets you evaluate the Software before deciding whether to buy. When the trial ends, continued full access requires the one-time purchase. No charge occurs unless and until you choose to purchase.

You retain full ownership of all Content you create using the Software, including arrangements, lyrics, notes, and any other materials. By using the Software, you grant us a limited right to store, display, and process your Content to provide the Service to you.

The Software, including its code, design, features, algorithms, and all underlying technology, is our exclusive property and is protected by copyright, trademark, and other intellectual property laws. You do not own the Software; you have only a limited license to use it as described in this Agreement.

Song structure templates provided with the Software are licensed to you for personal use. You may not redistribute, resell, or sublicense templates to others.

AI suggestions provided by the Software are creative assistance tools only and should not be considered professional musical or production advice. Final creative decisions remain entirely your responsibility.

While we strive for originality, we make no guarantee that AI suggestions are unique or original compositions. You are responsible for reviewing all AI suggestions and ensuring that your final Content does not infringe on any third-party rights.

We do NOT use your Content to train AI models. Your musical ideas and arrangements remain private and confidential. We may collect anonymized, non-identifying usage data to improve the Software's features and performance, but this data will never contain your personal Content or identify you individually.

AI Features are provided on an "as is" basis without warranty. AI capabilities may change, improve, or be discontinued at any time. We do not guarantee the accuracy, quality, or suitability of any AI suggestions for your creative purposes.

Beta features and early access features are provided for testing purposes and may contain bugs, errors, or incomplete functionality. You should not rely on beta features for critical projects.

Beta and early access features come with no warranty of any kind. We may discontinue, modify, or remove beta features without notice or compensation.

If you provide feedback, suggestions, or ideas about beta features or the Software in general, you grant us a perpetual, royalty-free license to use that feedback in any way we see fit without compensation or attribution to you.

Feature availability may vary for beta users. We will provide 30 days' notice before removing core features that were available in the main release.

arrangementLab is purchased with a single, one-time payment — there are no recurring or subscription fees. All fees are in USD and are processed by our payment provider, Polar, which acts as the merchant of record. You are responsible for any applicable taxes; Polar calculates and collects sales tax, VAT, or other taxes where required. We may change the price for future purchasers, but this never affects a purchase you have already completed.

We offer a 30-day money-back guarantee. If you are not satisfied with the Software within 30 days of your purchase, contact us at hello@arrangementlab.com to request a full refund of your one-time payment.

Payment is handled securely by Polar. If a payment does not complete successfully, the purchase is not finalized and no license key is issued — you simply retain access to the free trial (if still active) until you complete a purchase. Because arrangementLab is a one-time purchase, there are no recurring charges, retries, or grace periods to manage.

You may stop using the Software at any time. Because there is no account or subscription, there is nothing to cancel; you may simply discontinue use. If you wish to request a refund, see Section 8.2.

We may terminate this Agreement and your license to the Software if you materially violate this Agreement (for example, by redistributing or reverse-engineering the Software in breach of Section 2). We will not otherwise revoke a validly purchased license.

Your projects ("Content") are stored locally in your browser, not on our servers. Termination of this Agreement does not delete your local Content — it remains in your browser until you clear it. You are responsible for exporting any Content you wish to keep using the Software's export feature.

This Agreement, together with our Privacy Policy, constitutes the entire agreement between you and us regarding the Software and supersedes all prior negotiations, understandings, and agreements.

If any provision of this Agreement is found to be invalid or unenforceable, that provision shall be modified to the minimum extent necessary to make it valid, or if that is not possible, it shall be severed, and the remaining provisions shall remain in full force and effect.

Our failure to enforce any provision of this Agreement shall not constitute a waiver of that provision or any other provision.

You may not assign this Agreement or any rights hereunder to any third party without our prior written consent. We may assign this Agreement at any time without notice.
