License¶
This is the agreement the installer shows and that is installed with the
application as license.txt. It is included here from that same file, so
the two cannot say different things.
The third-party components it refers to, and where to obtain their sources,
are listed in thirdparty_libraries.txt, beside the application’s
documentation.
GIBBSSTUDIO END USER LICENCE AGREEMENT
Version 2.0, effective with GibbsStudio 6.1.0
Copyright (c) 2026 Albert Nardi and Luis Manuel de Vries.
All rights reserved.
IMPORTANT - READ BEFORE INSTALLING OR USING THIS SOFTWARE.
By installing or using the Software you agree to this Agreement. If you do
not agree, do not install or use the Software.
1. PARTIES AND DEFINITIONS
"The Licensors" means Albert Nardi and Luis Manuel de Vries, jointly, who
hold the rights in the Software. Where this Agreement says the Licensors do
or do not do something, it means both of them. They can be reached at
info@gibbsstudio.io.
"You" means the person or organisation accepting this Agreement.
"The Software" means the GibbsStudio application, its modules, its
documentation and its example projects, together with any updates the
Licensors make available to You.
"Module" means a separately licensed part of the Software, as listed under
Help > Plugins.
"Licence Key" means the licence file the Licensors issue to You, which
records the licence type, the modules it covers, the user and organisation
it is issued to, its start and end dates and, for a Commercial Licence, the
network addresses of the computers it is valid on.
"Third-Party Components" means the software listed in the file
thirdparty_libraries.txt supplied with the Software, which is licensed to
You by its own authors under its own terms and not under this Agreement.
2. LICENCE GRANT
Subject to this Agreement and to the terms recorded in Your Licence Key, the
Licensors grant You a non-exclusive, non-transferable licence, for the term
stated in the Licence Key, to install and use the Software and the Modules
the Licence Key covers, for Your own purposes.
Two kinds of Licence Key are issued:
(a) TRIAL LICENCE. Valid until the end date recorded in it, on any
computer, for evaluating the Software. Not for production work.
(b) COMMERCIAL LICENCE. Valid until the end date recorded in it, on the
computers whose network addresses are recorded in it, for the user
and organisation named in it.
Both kinds expire. The Software stops permitting licensed functions when
the end date passes, and the Licensors are under no obligation to issue a
replacement.
Use beyond what the Licence Key records - on more computers, after the end
date, or of Modules it does not cover - is not licensed.
The Software may be used without a Licence Key for whatever functions it
makes available without one. Those functions are licensed on the same terms
as the rest of this Agreement, including the disclaimers in sections 9 and
10.
3. WHAT YOU MAY ALSO DO
You may make copies of the Software as reasonably required to exercise the
licence, including backup copies.
You may distribute unmodified copies of the installer, provided You charge
nothing for them, make no claim to own the Software, and provide this
Agreement with them. A recipient needs their own Licence Key.
You may use results produced with the Software, including figures and
exported data, for any purpose, without restriction and without
acknowledgement. The Licensors claim no rights in Your models, Your data or
Your results.
You may use the Software to do work for Your clients and give them the
results, including the project files. That is not making the Software
available to a third party as a service under section 4(a), which is about
giving others access to the Software itself. A client who wants to run the
Software needs their own Licence Key.
4. WHAT YOU MAY NOT DO
Except as section 5 permits, and except where the law gives You a right that
this Agreement cannot remove, You may not:
(a) sell, rent, lease, sublicense or otherwise make the Software
available to a third party as a service;
(b) circumvent, remove or interfere with the Software's licence checking,
or use a Licence Key not issued to You;
(c) remove or alter any copyright or attribution notice;
(d) reverse engineer, decompile or disassemble the Software.
5. EXCEPTIONS TO SECTION 4
Section 4(d) does not apply:
(a) to the Third-Party Components, which You may reverse engineer,
modify, and relink to the extent their own licences allow or require.
Several are licensed under the GNU Lesser General Public Licence,
which entitles You to modify those components and to relink the
Software against Your modified versions, and to the information
necessary to do so. Their sources are available from the locations
listed in thirdparty_libraries.txt;
(b) where You have a right under Articles 5 or 6 of Directive 2009/24/EC
of the European Parliament and of the Council on the legal protection
of computer programs, or under equivalent law, to observe, study or
test the Software, or to decompile it to achieve interoperability;
(c) to anything else the applicable law does not permit to be prohibited.
6. OWNERSHIP
The Software is licensed, not sold. The Licensors and their suppliers retain
all rights in it that this Agreement does not expressly grant.
7. LICENCE KEYS AND VERIFICATION
The Software reads Your Licence Key from the computer it runs on and checks
it locally. It does not transmit the Licence Key to the Licensors.
To issue a Commercial Licence Key the Licensors need the network addresses
of the computers it is to run on, together with the name of the user and
organisation it is for. How that information is handled is described in the
privacy policy supplied with the Software.
The Software may check whether a newer version is available by contacting a
Licensors' server. The check sends no Licence Key and no personal data; what
the request carries is described in the privacy policy. It can be turned off
in Application Settings.
On some platforms the check only tells You that a newer version exists, and
You install it Yourself from the Licensors' website. The Licensors do not
undertake to provide an automatic update mechanism on any platform.
8. UPDATES AND SUPPORT
The Licensors may change the Software at any time and are not obliged to
update it, to support it, or to maintain compatibility with files produced
by other versions.
Updates are provided under this Agreement unless they come with terms of
their own.
9. NO WARRANTY, AND THE NATURE OF THE RESULTS
The Software is provided "as is", without warranty of any kind, express or
implied, including the implied warranties of merchantability, fitness for a
particular purpose and non-infringement, to the fullest extent the law
allows.
In particular, and importantly:
The Software is a scientific modelling tool. Its results depend on the
thermodynamic databases, the conceptual model, the input data and the
settings You choose, and on the assumptions built into the underlying
codes. Different databases give different answers to the same question. A
calculation that converges is not thereby correct.
The Licensors do not warrant that any result is accurate, complete or fit
for any purpose. Results must be reviewed by a person qualified to judge
them, and must not be relied upon as the sole basis for any decision
affecting health, safety, the environment, regulatory compliance or
engineering design.
The Software is not certified for, and must not be used for, any purpose
where its failure or an incorrect result could lead to death, personal
injury or severe environmental damage.
10. LIABILITY
Nothing in this Agreement limits or excludes liability for death or personal
injury caused by negligence, for fraud or fraudulent misrepresentation, for
wilful misconduct or gross negligence, or for anything else that the law
does not permit to be limited or excluded.
Subject to that:
(a) the Licensors are not liable for indirect or consequential loss, loss
of profit, loss of business, loss of data, loss of use, or for any
loss arising from reliance on a result produced with the Software;
(b) the Licensors' total liability arising out of or in connection with
this Agreement is limited, in aggregate, to the licence fees You paid
for the Software in the twelve months before the event giving rise to
the liability.
These limits apply however the liability arises, and even if the Licensors
were advised that the loss was possible. They reflect the price of the
Software and the fact that You, not the Licensors, control how its results
are used.
11. TERM AND TERMINATION
This Agreement runs for as long as You hold a valid Licence Key or use the
Software.
The Licensors may terminate it if You materially breach it and do not put
the breach right within 30 days of being asked to.
On termination You must stop using the Software and remove it from Your
computers. Sections 6, 9, 10, 12 and 13 survive termination. Results You
have already produced remain Yours.
12. EXPORT AND SANCTIONS
You must comply with the export control and sanctions laws that apply to the
Software, including those of the European Union. The Software includes
cryptographic components. You must not use it, or make it available, in
breach of those laws.
13. GOVERNING LAW
This Agreement is governed by the law of Spain, and the courts of Barcelona,
Spain have exclusive jurisdiction over any dispute arising from it.
If You are a consumer, this does not deprive You of the protection of the
mandatory rules of the law of the country where You live, and You may bring
proceedings in the courts of that country.
14. GENERAL
CONSUMER RIGHTS. If You are a consumer, Your statutory rights are not
affected by this Agreement, and any term that would exclude or limit them
does not apply to You.
RESALE WITHIN THE EU. Nothing in this Agreement prevents You from
exercising a right of resale that the law gives You notwithstanding section
4(a).
NOTICES. A notice to the Licensors under this Agreement is given by email to
info@gibbsstudio.io. A notice to You is given to the email address recorded
when Your Licence Key was issued. An emailed notice takes effect on the next
working day.
LANGUAGE. This Agreement is made in English. Any translation is supplied for
convenience only, and the English governs if the two differ.
SEVERABILITY. If any term is held unenforceable, the rest remains in force
and the unenforceable term applies to the fullest extent the law allows.
NO WAIVER. A failure to enforce a term is not a waiver of it.
ASSIGNMENT. You may not assign this Agreement without the Licensors'
written consent. The Licensors may assign it in connection with a transfer
of the rights in the Software.
ENTIRE AGREEMENT. This Agreement, together with the terms recorded in Your
Licence Key, is the whole agreement between You and the Licensors about the
Software, and replaces any earlier licence agreement supplied with it.
