License agreement

Version: 1.0

This document combines the requirements of the GNU General Public License (GPL v2) — required for publishing the free version of ShopWriter on WordPress.org — with the commercial API usage terms applied to ShopWriter’s free and paid API keys.

All plugin code distributed via WordPress.org repositories
is licensed under GPL v2 or later. API usage is commercially licensed.

1. GPL LICENSE (APPLICABLE TO THE WORDPRESS.ORG PLUGIN)

ShopWriter (Free) is licensed under the GNU General Public License, Version 2 (GPL v2) or any later version.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.

The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software—to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation’s software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.

When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if
you distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.

We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.

Also, for each author’s protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors’ reputations.

Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone’s free use or not licensed at all.

The precise terms and conditions for copying, distribution and
modification follow.

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The “Program”, below,
refers to any such program or work, and a “work based on the Program”
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term “modification”.) Each licensee is addressed as “you”.

Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program’s
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.

You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

(a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.

(b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any part
thereof, to be licensed as a whole at no charge to all third parties
under the terms of this License.

(c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but does
not normally print such an announcement, your work based on the
Program is not required to print an announcement.)

These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.

3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:

(a) Accompany it with the complete corresponding machine-readable
source code

NO WARRANTY (GPL SECTION 11)

THIS PROGRAM IS DISTRIBUTED IN THE HOPE THAT IT WILL BE USEFUL, BUT WITHOUT ANY WARRANTY; WITHOUT EVEN THE IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME ALL COSTS OF SERVICING, REPAIR OR CORRECTION.

2. SHOPWRITER COMMERCIAL LICENSE TERMS (APPLICABLE TO API USAGE)

There is no separate Pro plugin version. All plugin code is GPL, but certain features require a free or paid API key available via shop-writer.com/.

The plugin remains free and GPL. The API service is commercially licensed.

2.1 API License Grant

By obtaining a paid API key, you receive a non-transferable license to access and use the ShopWriter API within the limits of your subscription.

This API license is separate from the GPL license of the plugin.

2.2 API Usage Restrictions

The following restrictions apply only to API usage: – You may not share, sell, transfer, or publish your API key. – You may not misuse the API (including mass scraping, automated spam, or abusive automation). – You may not attempt to bypass authentication, rate limits, or security mechanisms. – You may not resell the API or its output as a standalone service without written permission.

These restrictions do not apply to the GPL plugin code.

2.3 Ownership

All rights to the API, platform logic, AI output services, and infrastructure remain the exclusive property of ShopWriter.

2.4 Updates & Access

Plugin updates are distributed under GPL.
Certain API-powered features require a valid API key.
API access is only available with a valid free or paid key.
Paid API features are only accessible while the subscription is active.

2.5 Termination of API Access

ShopWriter may suspend or terminate API access if: – the API terms are violated, – abuse or security risks are detected, – a subscription expires or is cancelled.

This does not affect your right to continue using the GPL plugin.

2.6 API Liability Disclaimer

To the fullest extent permitted by law: – ShopWriter shall not be liable for any damages arising from API usage, including incorrect AI output, downtime, data loss, business interruption, or indirect or consequential damages.

2.7 No Warranty for API Services

The API is provided “AS IS”, without any guarantee regarding availability, uptime, accuracy, or suitability for any purpose.

2.8 ShopWriter Trademark & proprietary rights

The ShopWriter name, logo, branding, cloud platform,
AI models, prompts, datasets, templates, backend services
and server-side infrastructure are proprietary and are not
licensed under the GPL.

2.9 No Competitive Use / Reverse Engineering

You may not use the API output to train external AI models
or datasets without written permission.

3. DUAL-LICENSING EXPLANATION

ShopWriter uses a hybrid licensing structure:

✔ Plugin Code → GPL v2 or later

The plugin code is licensed under GPL v2 or later.

✔ API Service → Commercial License

Users may not: – Share or sell API keys – Bypass rate limits or authentication – Resell the API output as a standalone service without permission

This model is fully compliant with WordPress.org’s licensing requirements.
