Terms of Service

Effective July 21, 2026 · Audiobook Studio for Mac, iPhone, and iPad

The short version: Audiobook Studio is a tool you install and run on your own device. The audiobooks you make are yours — we claim no rights to them. In return, you agree to use the app for audio you actually have the right to use, and to accept that software is provided as-is.

1. Agreement

These Terms are a legal agreement between you and Kuro Apps LLC, a Colorado limited liability company (“we”, “us”), covering the Audiobook Studio applications for macOS, iOS, and iPadOS (the “App”) and this website. By downloading, installing, or using the App, you agree to these Terms. If you do not agree, please do not use the App.

2. Licence to use the App

We grant you a personal, non-exclusive, non-transferable, revocable licence to use the App on devices you own or control, in accordance with the usage rules of the App Store it was obtained from. This is a licence, not a sale: we retain all ownership of the App itself.

You agree not to:

• copy, redistribute, resell, rent, or sublicense the App;
• reverse engineer, decompile, or disassemble the App, except to the extent that applicable law expressly permits it despite this limitation — including your rights under the open-source licences described in section 8;
• remove or obscure any copyright, trademark, or other proprietary notices.

3. Your content stays yours

You keep all rights to the audio files you import and to the audiobooks you create. We claim no ownership of, and no licence to, any of it. As described in our Privacy Policy, your files never leave your device, so we never receive, store, or have access to them in the first place.

4. Your responsibilities

Audiobook Studio is a general-purpose audio tool. You are responsible for having the legal right to use the audio you process with it. In particular, you agree that:

• you own the audio, have permission from the rights holder, or the material is in the public domain or otherwise licensed for your use;
• you will not use the App to infringe anyone's copyright or other rights;
• you will not attempt to use the App to remove, circumvent, or defeat digital rights management (DRM) or other technical protection measures. The App does not provide any such capability and cannot open DRM-protected files;
• you will comply with all laws that apply to you when using the App.

5. Third-party services

Optional features let you look up book information from third-party services, including Audible, Apple Books, Google Books, and Audnexus. Those services are operated by other companies under their own terms and privacy policies. We do not control them, do not guarantee their availability or the accuracy of what they return, and are not responsible for them. Information you retrieve through them may itself be subject to copyright and to those providers' terms.

6. Purchases, updates, and support

The App is distributed through Apple's App Store. All purchases, pricing, billing, and refunds are handled by Apple under Apple's terms — we cannot issue refunds directly, so please contact Apple for billing matters. We may release updates that add, change, or remove features, and we may stop supporting older operating system versions over time. Support is provided by us, not by Apple, at support@kuro-apps.com.

7. Back up your files

The App writes new audiobook files and can save project files. While it is designed not to modify your original source files, no software is perfect. You are responsible for maintaining backups of your audio and any other important data.

8. Open-source and bundled components

The App includes or can use third-party components under their own licences, including the LAME MP3 encoder and mpg123 library (LGPL, in the direct-download Mac edition) and, optionally, the exhale xHE-AAC encoder, which you install yourself from its official source. Those licences govern those components, and nothing in these Terms limits your rights under them. Acknowledgements and licence texts are available in the App's settings.

The App also bundles a sample audiobook — “Just So Stories” by Rudyard Kipling, read by Kara Shallenberg for LibriVox — which is in the public domain and free for you to use and share.

9. Disclaimer of warranties

The App is provided “as is” and “as available”, without warranties of any kind, whether express, implied, or statutory, including any 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 compatible with every file, device, or player, or that any output will meet your requirements. Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you.

10. Limitation of liability

To the maximum extent permitted by law, Kuro Apps LLC will not be liable for any indirect, incidental, special, consequential, or exemplary damages, or for any loss of data, files, profits, or goodwill, arising out of or relating to your use of or inability to use the App — even if we have been advised of the possibility of such damages. Our total liability for any claim relating to the App will not exceed the amount you paid for it. Some jurisdictions do not allow these limitations, so they may not fully apply to you.

11. Termination

These Terms apply for as long as you use the App. Your licence ends automatically if you materially breach them, and you may end it at any time by deleting the App. Sections 3, 4, and 9 through 12 survive termination.

12. Changes to these Terms

We may update these Terms from time to time. The current version will always be posted here with its effective date. Continuing to use the App after an update means you accept the revised Terms.

13. Governing law

These Terms are governed by the laws of the State of Colorado, United States, without regard to its conflict-of-law rules, and you and we agree to the exclusive jurisdiction of the state and federal courts located in Colorado. Nothing here removes any mandatory consumer-protection rights you have under the laws of your own country or state.

14. Apple App Store terms

The following apply to the App as obtained through Apple's App Store:

• These Terms are between you and Kuro Apps LLC only, not with Apple. Apple is not responsible for the App or its content.
• Your licence to use the App is limited to a non-transferable licence to use it on Apple-branded devices you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.
• Apple has no obligation to provide maintenance or support for the App. Support requests should come to us.
• If the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App.
• We, not Apple, are responsible for addressing any claims relating to the App, including product liability claims, claims that it fails to conform to legal requirements, and consumer-protection claims.
• We, not Apple, are responsible for investigating and resolving any third-party claim that the App infringes that party's intellectual property rights.
• 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 its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
