IMPORTANT - READ CAREFULLY. This End User License Agreement ("Agreement")
is a legal agreement between you ("you" or "User") and the NarrationOS
project and its authors ("we", "us", or "Licensor") for the NarrationOS
desktop application and all associated software, scripts, and documentation
(collectively, the "Software").
BY INSTALLING, COPYING, OR OTHERWISE USING THE SOFTWARE, YOU AGREE TO BE
BOUND BY THE TERMS OF THIS AGREEMENT. IF YOU DO NOT AGREE TO THESE TERMS, DO
NOT INSTALL OR USE THE SOFTWARE.
1. LICENSE GRANT
Subject to your compliance with this Agreement and your payment of any
applicable purchase price, Licensor grants you a non-exclusive,
non-transferable, perpetual license to install and use the Software on
devices you own or control.
This Agreement governs your license to the NarrationOS application itself. It
does not restrict your rights in the audio or other output you generate with
the Software: subject to Section 6 (User Content) and the third-party terms in
Section 5, you may use the output you create (including for commercial
purposes) to the extent those third-party licenses permit. The Software was
purchased through a third-party storefront (such as itch.io or Steam); your
purchase, payment, and refunds are also governed by that storefront's terms.
2. RESERVATION OF RIGHTS; OWNERSHIP
The Software is licensed, not sold. Licensor and its licensors retain all
right, title, and interest in and to the Software, including all
intellectual property rights therein. All rights not expressly granted to
you in this Agreement are reserved by Licensor. This Agreement does not
grant you any rights in the third-party components described in Section 5,
which are licensed to you directly by their respective licensors under their
own terms.
3. RESTRICTIONS
You shall not, and shall not permit any third party to:
(a) sell, rent, lease, sublicense, distribute, or otherwise commercially
exploit the Software;
(b) reverse engineer, decompile, or disassemble the Software, except to
the extent such restriction is expressly prohibited by applicable law
or by the license terms of a third-party component included in the
Software (see Section 5);
(c) remove, alter, or obscure any proprietary notices on the Software;
(d) use the Software to create audio or other output that infringes the
rights of any third party, or that violates any applicable law,
including the third-party terms referenced in Section 5.
4. FIRST-RUN SETUP; NETWORK ACCESS; THIRD-PARTY DOWNLOADS
You acknowledge that, on first launch, the Software installs additional
third-party components required for it to function, including but not limited
to: a Python runtime and machine-learning libraries (including PyTorch), the
Chatterbox text-to-speech system and its model weights, the Ollama local
large-language-model runtime, and one or more language models (including, by
default, Alibaba Cloud's Qwen3.5 4B model). Depending on your hardware and
configuration, some of these components are bundled with the Software and
installed offline, while others may be downloaded over the internet, which may
transfer several gigabytes of data. In particular, on systems without a
supported NVIDIA GPU the matching PyTorch build is downloaded on first launch,
and the Chatterbox model weights are downloaded from their provider on first
use. By proceeding you authorize the Software to install, download (where
applicable), and run these components on your device.
5. THIRD-PARTY COMPONENTS AND TERMS
The Software incorporates, downloads, or otherwise relies on third-party
software and models, each governed by its own license or terms of use. Those
components are provided under their own licenses and not under this
Agreement; nothing in this Agreement limits any rights you have, or
obligations Licensor has, under those licenses. By installing and using the
Software you also agree to be bound by the following third-party terms, to
the extent they apply to your use. Full texts and attributions are provided
in the "licenses" folder of this installation (see also the NOTICE file).
(a) QWEN3.5 4B (Alibaba Cloud) — The default language model is Qwen3.5 4B
(qwen3.5:4b), run locally via Ollama. It is licensed under the Apache
License, Version 2.0, which permits commercial use, modification, and
redistribution with no royalties or usage caps.
Model card (apache-2.0): https://huggingface.co/Qwen/Qwen3.5-4B
Ollama model: https://ollama.com/library/qwen3.5:4b
(NOTE: the Qwen3/Qwen3.5 open-weight checkpoints, including the default
qwen3.5:4b, are Apache 2.0. Some older Qwen/Qwen2/Qwen2.5 models are
instead under Alibaba's "Tongyi Qianwen License" (which requires a
separate license above 100M monthly active users) or a non-commercial
"Qwen Research License". NarrationOS installs the Apache-2.0 qwen3.5:4b
by default; if you choose a different model in Settings, that model's
own license/terms apply to your use of it.)
(b) CHATTERBOX (Resemble AI) — The text-to-speech engine and its model
weights are licensed under the MIT License (Copyright (c) 2025
Resemble AI). Audio generated by Chatterbox includes Resemble AI's
imperceptible "Perth" neural watermark. See:
https://github.com/resemble-ai/chatterbox/blob/master/LICENSE
(c) OLLAMA — The local LLM runtime is licensed under the MIT License. See:
https://github.com/ollama/ollama/blob/main/LICENSE
(d) PYTORCH and related Python libraries — Provided under their respective
open-source licenses (PyTorch: BSD-3-Clause). The specific PyTorch
build installed is selected to match your hardware (CPU/GPU). On systems
with a supported NVIDIA GPU, the bundled NVIDIA CUDA build of PyTorch
includes NVIDIA proprietary runtime libraries (the "cu12" packages, e.g.
CUDA runtime, cuBLAS, cuDNN), which are NOT covered by PyTorch's BSD
license and are governed by NVIDIA's own license terms and the NVIDIA
CUDA Toolkit End User License Agreement
(https://docs.nvidia.com/cuda/eula/). Those libraries are redistributed
as a component of the Software, which provides material additional
functionality beyond the CUDA SDK, as that EULA permits. Each NVIDIA
component's license is included in its package metadata in the installed
runtime.
(e) FFMPEG — The Software bundles an FFmpeg build licensed under the GNU
Lesser General Public License, version 3 (LGPL v3), used for audio
encoding and export. The corresponding FFmpeg license text is included
in the "licenses" folder, and FFmpeg source corresponding to the
bundled build is available from the FFmpeg project and its builder.
See: https://ffmpeg.org and https://github.com/BtbN/FFmpeg-Builds
(f) OTHER OPEN-SOURCE COMPONENTS — The Software and its runtime bundle
additional open-source packages (e.g. spaCy, NumPy, libsndfile via
python-soundfile, librosa, FastAPI, and others), each under its own
permissive or LGPL license. These are reproduced in the NOTICE file
and in each package's metadata installed alongside the runtime.
You are solely responsible for reviewing and complying with these
third-party terms. If you do not agree to any of them, do not install or
use the Software.
6. USER CONTENT
You are solely responsible for any books, text, audio, voice samples, or
other content you import into or generate with the Software. You represent
that you have the necessary rights to use such content, and that your use of
voice cloning and narration features complies with all applicable laws and
the rights of any persons whose voice or likeness may be involved.
7. CONSUMER RIGHTS (AUSTRALIA AND OTHER JURISDICTIONS)
Nothing in this Agreement excludes, restricts, or modifies any consumer
guarantee, right, or remedy that you have under the Australian Consumer Law
(Schedule 2 to the Competition and Consumer Act 2010 (Cth)) or any other
applicable law that cannot lawfully be excluded or limited.
If you acquired the Software outside Australia, mandatory consumer-protection
laws of the country or region where you live (for example, in the United States,
the United Kingdom, the European Union, or elsewhere) may give you rights and
remedies that cannot be excluded by contract. Nothing in this Agreement
(including the governing-law clause in Section 12) excludes, restricts, or
modifies any such right or remedy; where they apply, they apply in addition to,
and prevail over, any inconsistent term of this Agreement. References below to
the Australian Consumer Law are illustrative of this principle and do not limit
the protections available to you under your local law.
Our goods and services come with guarantees that cannot be excluded under the
Australian Consumer Law. For major failures with the service, you are entitled:
to cancel your service contract with us; and to a refund for the unused portion,
or to compensation for its reduced value. You are also entitled to choose a
refund or replacement for major failures with goods. If a failure with the goods
or a service does not amount to a major failure, you are entitled to have the
failure rectified in a reasonable time. If this is not done you are entitled to a
refund for the goods and to cancel the contract for the service and obtain a
refund of any unused portion. You are also entitled to be compensated for any
other reasonably foreseeable loss or damage from a failure in the goods or
service.
Sections 8 and 9 (and any other limitation or exclusion in this Agreement)
apply only to the extent permitted by law and are subject to this Section 7.
Where Licensor is permitted to limit its liability for a failure to comply with
a non-excludable guarantee, Licensor's liability is limited, at Licensor's
option, to (for goods) replacing the goods or supplying equivalent goods, or
repairing the goods, or paying the cost of doing so; and (for services)
re-supplying the services or paying the cost of having them re-supplied.
8. DISCLAIMER OF WARRANTIES
SUBJECT TO SECTION 7, AND TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW,
THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY
KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.
LICENSOR DOES NOT WARRANT THAT THE SOFTWARE WILL BE UNINTERRUPTED OR
ERROR-FREE.
9. LIMITATION OF LIABILITY
SUBJECT TO SECTION 7, AND TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW,
IN NO EVENT SHALL LICENSOR BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL,
CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS OR DATA, ARISING
OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE SOFTWARE, EVEN IF
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. SUBJECT TO SECTION 7, LICENSOR'S
TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THIS AGREEMENT WILL NOT
EXCEED THE AMOUNT YOU PAID FOR THE SOFTWARE.
10. PURCHASE; STOREFRONT TERMS
You obtained the Software through a third-party storefront (such as itch.io or
Steam). Your purchase of, payment for, and any refund of the Software are
handled by, and governed by the terms and policies of, that storefront (for
example, the Steam Subscriber Agreement and Valve's refund policy, or itch.io's
terms). Nothing in this Agreement limits any refund or other right you have
under those storefront terms or under applicable law, including Section 7.
11. TERMINATION
This Agreement is effective until terminated. Your rights under this
Agreement will terminate automatically without notice if you fail to comply
with any of its terms. Upon termination you must cease all use of the
Software and uninstall it. Sections 2, 5, 6, 7, 8, 9 and 12 survive
termination.
12. GOVERNING LAW; GENERAL
This Agreement is governed by the laws of Queensland, Australia, and the
Commonwealth of Australia, without regard to conflict-of-laws rules, and you
submit to the non-exclusive jurisdiction of the courts of that State. Nothing
in this Section limits any right you have to bring proceedings, or rely on
mandatory consumer protections, under the law of the place where you live.
This Agreement constitutes the entire agreement between you and Licensor
concerning the Software and supersedes all prior agreements. If any
provision is held to be unenforceable, the remaining provisions will remain
in full force and effect.
By clicking "I Agree" or by installing or using the Software, you
acknowledge that you have read this Agreement, understand it, and agree to
be bound by its terms, including the third-party terms referenced above.
