Licensaftale (EULA)

Licensaftalen er ét dokument for alle programmer i serien og for det gratis Revit-plugin, i fem dele: I — generelle vilkår, II — Free-versionen og pluginnet, III — prøveperioden, uddannelseslicensen og betalicensen, IV — Pro, V — privatliv og forbindelser. Et program viser den i fuld længde ved første start. Engelsk er aftalens bindende sprog; resuméerne er til orientering. For Servicevilkårene gælder, at den danske version er bindende for forbrugere med bopæl i Danmark. I teksterne nedenfor står [program] for det enkelte programs navn.

Resumé

Én licensaftale for alle programmer i CPH HVAC Studio Engineering Tools og for Revit-pluginet: Del I gælder for alle, del II for Free-versionen og pluginet, del III for en prøveperiode, en uddannelseslicens og en betalicens, del IV for Pro, og del V forklarer, hvad programmerne sender.
Free-versionen er gratis for alle, også til erhvervsmæssigt arbejde; Pro licenseres pr. person og år. Den uændrede Free-installationsfil må kun videregives gratis og sammen med denne licensaftale. Revit-pluginet er altid gratis.
Intet salg, ingen ændring, dekompilering eller reverse engineering, ud over hvad loven tillader; ingen omgåelse af licenskontrollen; kildeangivelsen »Made with [program]« på eksporterede dokumenter skal bevares.
Programmerne er hjælpemidler i projekteringen for kvalificerede fagfolk inden for HVAC: alle resultater skal kontrolleres af en kvalificeret ingeniør, som fortsat har ansvaret for projekteringen.
Prøveperiode: Pro gratis i 30 dage, én pr. computer og én pr. konto for hvert program; den bliver på én computer og kræver forbindelse, når programmet starter. Dokumenter fra prøveperioden er mærket »Prøveversion — ikke til udlevering«.
Uddannelseslicens: Pro gratis efter ansøgning for nuværende studerende og undervisere ved en uddannelsesinstitution, kun til undervisning, studier og ikke-kommerciel forskning — ikke til betalt arbejde eller arbejde for kunder; 12 måneder, som kan fornyes ved en ny ansøgning. Dokumenterne er mærket »Undervisning — ikke til udlevering«. Som Pro kører den på én computer ad gangen.
Betalicens: Pro gratis for betatestere i den periode, vi fastsætter, givet i din konto eller med en kampagnekode; kommercielt arbejde er tilladt, og dokumenterne er ikke mærket. Som Pro kører den på én computer ad gangen.
Pro: et årligt abonnement pr. person (plads) for ét program eller for alle programmer, købt via vores forhandler Paddle efter servicevilkårene (Terms of Service). Pro kører på én computer ad gangen og virker uden internet i op til 7 dage; til lukkede netværk findes offline-aktivering.
Pro virker, så længe din licens er gyldig. Når en licens ophører — ved udgangen af det betalte år uden fornyelse, efter en refusion eller et ophør før tid, efter en ophævelse på grund af misligholdelse eller ved udgangen af en prøveperiode, en uddannelseslicens eller en betalicens — virker programmet som Free: alle projekter kan stadig åbnes, og deres Pro-data bevares, men er låst, indtil Pro igen er gyldig. Ingen version forbliver Pro, efter at licensen er ophørt.
Opdateringer fører kun til den nyeste version: Free-versionen får dem altid, Pro, så længe din licens er gyldig. Rettelser, også sikkerhedsrettelser, kommer kun i den nyeste version. Hvert program får sikkerhedsopdateringer i mindst fem år fra dets første udgivelse med Pro til salg (når det bringes i omsætning); måned og år står på tools.cphhvacstudio.dk/security/, og hver sikkerhedsopdatering forbliver tilgængelig i mindst ti år. Sårbarheder indberettes til security@cphhvacstudio.dk.
Free-versionen, pluginet, en prøveperiode, en uddannelseslicens og en betalicens leveres »som de er«; vores ansvar for dem er udelukket eller i hvert fald begrænset til 500 kr. For Pro er ansvaret begrænset til betalingen for de seneste 12 måneder, dog mindst prisen for én årslicens. Ansvar, som loven ikke tillader os at udelukke, består.
Programmet kontakter kun vores servere ved en ugentlig søgning efter opdateringer (som du kan slå fra), ved login og licenskontrol, når du er logget ind, og ved problemrapporter, du selv sender; det sender aldrig dine projektdata, bortset fra en fil, du vedhæfter en rapport.
Dansk ret finder anvendelse; dine ufravigelige rettigheder, herunder dine rettigheder som forbruger, berøres ikke.
Kun den engelske tekst af licensaftalen er juridisk bindende; dette resumé er alene til orientering.

mandatory law that applies regardless of that choice.

2. ACCEPTANCE AND STRUCTURE OF THIS LICENSE
2.1 This License is one agreement for all Programs and the Plugin. The Software shows it in full
before its first use, so that you can read, save and print it before you accept it. A copy is
installed as LICENSE.txt in the installation folder, the Software shows it on request (in the
Programs: Help → License agreement), and it is published at tools.cphhvacstudio.dk/eula/.
2.2 Part I applies to all use of the Software. Part II applies to the Free version and to the
Plugin. Part III applies while you use the Pro Features under a Trial, an Education License or
a Beta License, and Part IV while you use them under a Pro License. Part V applies to all use.
If a provision of Part II, III or IV conflicts with Part I, the provision of that Part
prevails for the use concerned.
2.3 Everyone who uses the Software accepts this License for himself or herself. For a Pro License,
the roles of the Customer, which buys the Seats, and of the Users, to whom they are assigned,
are set out in Section 25.3.
2.4 Pro Licenses are bought through the Licensor's reseller Paddle.com, which is the Merchant of
Record for all orders. The purchase is governed by the Terms of Service and by Paddle's buyer
terms; this License governs the use of the Software.
2.5 The Software is licensed, not sold. All rights not expressly granted are reserved.

3. RESTRICTIONS
3.1 Except as expressly permitted by this License, and except to the extent that a restriction is
not permitted by Applicable Law (see Section 4), you may not, and may not allow others to:
(a) sell, rent, lease or sublicense the Software or a License, or otherwise charge for the
Software, for copies of it or for access to it, including by bundling or including it in
any paid product, software package, service or distribution, or by offering it as a hosted
or remote service;
(b) modify, translate, adapt, arrange or otherwise alter the Software, or create derivative
works based on it;
(c) decompile, disassemble, reverse engineer or otherwise attempt to derive the source code,
algorithms, structure or internal data of the Software;
(d) remove, alter, obscure or hide any copyright notice, trademark, logo, license text, the
credit line in Exported Documents (Section 7.3), the trial or education mark (Sections
22.4 and 23.4) or any other notice in the Software or in Exported Documents;
(e) circumvent, disable or interfere with the license check of the Software or any other
technical measure that limits the use of the Pro Features, or use an Account, session,
license file or Offline Activation of another person, or one that was not issued for the
computer concerned; or
(f) use the Software in breach of any applicable law, including export control and sanctions
law.
3.2 Section 3.1(a) does not prevent you from charging for your own engineering, consulting or
design services in which you use the Software or its Results, except where Part III limits the
purposes for which a Trial or an Education License may be used.

4. RIGHTS THAT CANNOT BE EXCLUDED BY CONTRACT
4.1 Nothing in this License restricts any act that a lawful user is entitled to perform under
mandatory law, including Articles 5 and 6 of Directive 2009/24/EC on the legal protection of
computer programs and §§ 36 and 37 of the Danish Copyright Act (ophavsretsloven). This
includes the right to:
(a) make a back-up copy where necessary for the use of the Software;
(b) observe, study or test the functioning of the Software in order to determine the ideas and
principles underlying it, while loading, displaying, running or storing it;
(c) reproduce and translate code where indispensable to obtain the information necessary to
achieve the interoperability of an independently created program, within the conditions
and limits set by law; and
(d) correct errors where necessary for the use of the Software in accordance with its intended
purpose, to the extent that this right cannot be excluded by contract.
4.2 Information necessary for interoperability can be requested from the Licensor at
office@cphhvacstudio.dk. To the extent permitted by law, you must request it from us before
taking any step under Section 4.1(c).
4.3 Please report errors to us. Except as Section 9 and Part IV provide, we may, but are not
obliged to, correct them in a later version.

5. OWNERSHIP AND INTELLECTUAL PROPERTY
5.1 The Software, including its code, user interface, chart and report layouts, graphics, help
texts and documentation, is protected by copyright and other intellectual property laws. All
rights, title and interest in the Software belong to the Licensor or its licensors. The
Third-Party Components belong to their respective owners.
5.2 As between you and the Licensor, you own your Project Data, Results and Exported Documents,
and the Licensor claims no rights in them. To the extent Exported Documents contain elements
protected by the Licensor's rights, such as chart or report layouts or the credit line, the
Licensor grants you a free, perpetual, worldwide license to use, copy, publish and distribute
those elements as part of your Exported Documents for any lawful purpose, subject to Section 7
and to the marks of Part III.
5.3 If you send us suggestions or error reports, we may use them freely and without any obligation
to you.

6. THIRD-PARTY COMPONENTS
6.1 The Software includes Third-Party Components, each licensed under its own license. The
complete list, with the notices that their licenses require, is given in the file
THIRD_PARTY.txt in the installation folder (in the Programs also under Help → Third-party
components).
6.2 Each Third-Party Component is governed by its own license. If that license conflicts with this
License, that license prevails for that component, and nothing in this License limits the
rights that you have under it for the component itself.
6.3 Third-Party Components are provided by their licensors without warranty. Sections 20, 21, 30
and 31 also apply to them, in favour of the Licensor and, to the extent permitted, of their
licensors.
6.4 The Plugin works inside Autodesk Revit, which is licensed separately by Autodesk. This License
grants no right to use Autodesk Revit.

7. EXPORTED DOCUMENTS AND CREDIT LINE
7.1 Where the Software lets you add your own or your client's logo, company name, contact details
and project information to Exported Documents, you must have the right to use them. You are
responsible for that content.
7.2 You may use, copy, publish and deliver Exported Documents for any lawful purpose, including in
paid projects, subject to Section 7.3 and to the marks and purposes of Part III.
7.3 The Software adds the credit line "Made with [program] · cphhvacstudio.dk" to Exported
Documents, in the Free version and in Pro. You may not remove, alter, cover, crop or make
illegible this credit line, whether in the Software or afterwards, in any Exported Document or
copy of it that you publish, deliver or otherwise make available to others. If an Exported
Document, such as a chart, is inserted into a larger document, its credit line must remain
visible with it.
7.4 The credit line only identifies the tool used. It does not mean that the Licensor has
reviewed, verified or approved the Results or the project, and you must not state or imply
otherwise.

8. INTENDED USE AND RESULTS
8.1 The Software is a design aid intended for qualified HVAC professionals. It does not provide
engineering advice and does not replace professional judgement. Before Results are used for
design, dimensioning, equipment selection, tenders, construction, commissioning, operation or
any other decision, they must be checked by a qualified engineer, including input data,
assumptions, units, boundary conditions and the validity ranges stated in the documentation.
You, or the organisation for which you work, remain solely responsible for the design and for
compliance with applicable laws, building codes, standards, project specifications and
manufacturers' data and instructions.
8.2 The calculation methods of each Program, and the standards and handbooks on which they are
based, are named in its documentation and in its About window. Results are approximations that
depend on the input and may differ from those of other methods, editions or tools. References
to standards and guidelines identify the calculation basis; check them against the edition
that applies to your project.
8.3 Results that depend on data you enter, such as manufacturer performance data or material
properties, are balance calculations. They are not manufacturer selections, performance
guarantees or certifications; actual equipment performance must be confirmed by the
manufacturer.
8.4 The Software is not designed for real-time control of equipment, for life-safety systems, or
for use as the sole basis of any decision where an error could cause death, personal injury or
significant damage to property.

9. UPDATES, SECURITY UPDATES AND SUPPORT
9.1 The Programs and the Plugin can check for updates and tell you when a new version is available
(Part V). An update is installed only when you choose to install it, and the Software does not
replace its own files while it runs. Updates lead only to the Latest Version: the Free version
receives them always, the Pro Features while a License for them is valid (Section 27).
9.2 For each Program, the Licensor provides security updates for at least five years from the
first release of the Program for which Pro Licenses are sold (its placing on the market), and
for the Plugin from its first public release; this is its Support Period. Fixes, including
security fixes, are released only in the Latest Version, as a new version; earlier versions
are not updated separately. The Latest Version is available to everyone as the Free version,
and with the Pro Features to Users whose License is valid. Each Security Update remains
available for at least ten years after its release, or until the end of the Support Period if
that is later. The page tools.cphhvacstudio.dk/security/ states for each Program and for the
Plugin the month and year until which security updates are provided at least, and the
checksums of the installers; the same date is shown before a purchase.
9.3 Please report security vulnerabilities to security@cphhvacstudio.dk. The page
tools.cphhvacstudio.dk/security/ (in the Programs: Help → Report a vulnerability…) describes
how to report them and how we handle reports.
9.4 Apart from Section 9.2, Part IV and your rights under mandatory law, the Licensor has no
obligation to provide support, maintenance, error correction, updates, upgrades or new
versions, or to keep the Free version or the Free Installer available. Support is given by
e-mail, voluntarily and free of charge, and Sections 20, 21, 30 and 31 apply to it.
9.5 Notices of known errors are published with the updates and on tools.cphhvacstudio.dk. Install
updates and read these notices before you rely on Results in a project.

10. YOUR RESPONSIBILITIES AND INDEMNITY
10.1 You are responsible for choosing the Software for your purpose, for your input data, for
checking the Results (Section 8.1), for backing up your Project Data, for the content that
you add to Exported Documents, and for keeping the sign-in codes of your Account to yourself.
10.2 If you are a Business User, you shall indemnify and hold the Licensor harmless against all
third-party claims and related losses, damages and reasonable costs (including reasonable
legal fees) arising out of (a) your breach of this License, (b) your misuse of the Software
or the Results, including any use contrary to Section 8, such as using Results that have not
been checked by a qualified engineer, or (c) content that you add to Exported Documents. This
does not apply to the extent that the claim was caused by the Licensor's intent or gross
negligence. The Licensor will inform you of any such claim without undue delay.
10.3 Section 10.2 does not apply to Consumers. A Consumer is liable only under the general rules
of Applicable Law.

11. TERMINATION
11.1 This License applies from your acceptance or first use of the Software and continues until it
is terminated.
11.2 If you materially breach this License, in particular Section 3, 7.3 or 19 or the conditions
of Part III, the Licensor may terminate this License and your Trial, Education License or
Beta License by notice, given by e-mail to the address of your Account or, if you have no
Account, in any other suitable way. For the Free version, this License also terminates
automatically, without notice, if you breach Section 3, 7.3 or 19.
11.3 A Pro License is terminated for breach only under Section 32.2.
11.4 You may terminate this License at any time by uninstalling the Software and deleting all
copies of it. This does not cancel the subscription of a Pro License: cancellation, early
termination and refunds are governed by the Terms of Service.
11.5 On termination, you must stop using the Software and delete all copies of the Software, the
Installers and license files in your possession or control. Exported Documents created before
termination may still be used, provided that Section 7.3 and the marks and purposes of Part
III are complied with.
11.6 Sections 4, 5, 7.3, 7.4, 8, 10, 11.5, 13 to 16, 20, 21, 30 and 31 survive termination.

12. CHANGES TO THIS LICENSE
12.1 The Licensor may change this License for future versions of the Software and for future
License Terms. A changed edition is published at tools.cphhvacstudio.dk/eula/ and is shown by
the Software before you use a version to which it applies. If you do not accept it, you may
continue to use the versions you have under the edition that you accepted for them.
12.2 Holders of a Pro License are informed of a change by e-mail at least 30 days before it
applies to them. A change applies to them from the next renewal of the Pro License; the
edition that they accepted continues to apply until the end of the current License Term. If
you do not agree to a change, you can cancel the renewal as described in the Terms of
Service. Changes of the Terms of Service for a renewed License Term are likewise notified at
least 30 days before the renewal (Terms of Service, section 14).

13. TRADEMARKS
13.1 "CPH HVAC Studio", "CPH HVAC Studio Engineering Tools", the names of the Programs and the
Plugin, and the CPH HVAC Studio logo are trademarks of the Licensor. This License grants no
right to use them, except to refer accurately to the Software in unmodified form, for example
when passing on the Free Installer under Section 19 or stating that a document was made with
it.
13.2 Names of standards, publications, organisations and products of third parties that appear in
the Software, such as ASHRAE, are trademarks of their respective owners. The Software is not
affiliated with, endorsed, sponsored, certified or approved by them; references to their
publications only identify the calculation basis. Autodesk and Revit are registered
trademarks of Autodesk, Inc. Microsoft and Windows are trademarks of the Microsoft group of
companies. Names of methods and charts, such as "Mollier" and "Carrier", are used
descriptively and do not imply any affiliation or endorsement.

14. GOVERNING LAW AND JURISDICTION
14.1 This License and any dispute or claim arising out of or in connection with it, including
non-contractual disputes or claims, are governed by Danish law, excluding its conflict-of-law
rules. The United Nations Convention on Contracts for the International Sale of Goods (CISG)
does not apply.
14.2 The Danish courts have exclusive jurisdiction, with the Copenhagen City Court (Københavns
Byret) as the court of first instance, unless mandatory rules of Danish procedural law
provide otherwise. This does not prevent the Licensor from applying for interim measures, or
from bringing proceedings for infringement of its intellectual property rights, before any
other court that has jurisdiction under applicable law.
14.3 If you are a Consumer, Section 14.1 does not deprive you of the protection of mandatory
provisions of the law of your country of habitual residence, and Section 14.2 does not
deprive you of your right to bring or defend proceedings before the courts that have
jurisdiction under mandatory consumer protection rules. The Terms of Service name the bodies
to which a Consumer can complain.

15. SEVERABILITY
15.1 If any provision of this License is held to be invalid, unenforceable or not binding, the
other provisions continue to apply. In relation to a Business User, the provision shall apply
to the maximum extent permitted and otherwise be replaced by a valid provision that comes as
close as possible to its purpose. In relation to a Consumer, the provision shall simply be
disregarded to the extent that it is not binding.

16. ENTIRE AGREEMENT, LANGUAGE AND TRANSFER
16.1 This License, together with the Terms of Service for a Pro License and with the license texts
of the Third-Party Components, is the entire agreement between you and the Licensor
concerning the Software and supersedes all prior agreements and understandings concerning its
subject matter.
16.2 This License is written in English, and the English text is binding. Summaries and
translations in other languages are provided for information only. In case of any conflict,
the English text prevails, unless mandatory law provides otherwise.
16.3 The Licensor may transfer this License and its rights and obligations under it to an
affiliated company or to a successor of its business; such a transfer does not reduce your
rights under this License. You may not transfer this License or a License, except that a
Customer assigns Seats and Seats are transferred under Section 29; recipients of the Free
Installer receive their own license under Section 19.2.
16.4 Failure or delay by the Licensor in enforcing any provision is not a waiver of its rights.

PART II — THE FREE VERSION AND THE REVIT PLUGIN

18. FREE LICENSE
18.1 Subject to your compliance with this License, the Licensor grants you a free-of-charge,
non-exclusive, non-transferable, worldwide license, for the term set out in Section 11, to
install and use the Free version of the Software and the Plugin on any number of computers
that you own or control, for any lawful purpose: private, educational or commercial.
Commercial use includes using the Software and its Results in paid engineering work for your
clients or your employer.
18.2 A Business User may allow its employees and contractors to use the Free version and the
Plugin on its behalf and is responsible for their compliance with this License.
18.3 You may make back-up copies of the Software and of the Free Installer.
18.4 No fee, royalty or other payment is due to the Licensor for use under this Part II. The Free
version can be used without an Account.
18.5 The Plugin is always free of charge and is licensed under this Part II. The exchange of data
between a Program and Autodesk Revit through the Plugin uses the Pro Features of that
Program.

19. COPYING AND REDISTRIBUTION
19.1 You may copy the Free Installer and the installer of the Plugin and pass them on to others
only if all of the following conditions are met:
(a) it is done free of charge: you do not request or receive any fee, price, subscription,
membership, service charge or other consideration, directly or indirectly, for the
Software, for a copy of it or for access to it (including by making a download
conditional on a purchase, a paid membership or the installation of other software);
(b) you pass on only the complete, unmodified original installer as published by the
Licensor, and not modified, repackaged, partial or extracted files;
(c) this License accompanies the installer, and you do not offer or impose any other or
additional terms for the Software; and
(d) you do not state or imply that you are the author or publisher of the Software, or that
the Licensor endorses you or your products or services.
19.2 Each recipient receives a license to the Software directly from the Licensor under this
License. You cannot grant anyone any rights in the Software.
19.3 A Business User may make the Free Installer and the installer of the Plugin available on its
internal network so that its own employees and contractors can install the Software, subject
to Section 19.1.
19.4 Sections 19.1 to 19.3 do not apply to the Pro Installer, which may not be passed on (Section
25.5).

20. NO WARRANTY (FREE VERSION, PLUGIN, TRIAL, EDUCATION AND BETA LICENSE)
20.1 THE FREE VERSION, THE PLUGIN, A TRIAL, AN EDUCATION LICENSE AND A BETA LICENSE ARE PROVIDED
FREE OF CHARGE, "AS IS" AND "AS AVAILABLE", WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND.
To the maximum extent permitted by Applicable Law, the Licensor disclaims all warranties,
conditions, guarantees and representations, whether express, implied or statutory, including
as to merchantability, satisfactory quality, fitness for a particular purpose, accuracy,
completeness or reliability of Results, non-infringement, compatibility, and error-free or
uninterrupted operation. The Licensor does not warrant that the Software or the Results will
meet your requirements or comply with any standard, code or regulation.
20.2 Section 8 applies in full.

21. LIMITATION OF LIABILITY (FREE VERSION, PLUGIN, TRIAL, EDUCATION AND BETA LICENSE)
21.1 TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE LICENSOR SHALL NOT BE LIABLE FOR ANY
LOSS OR DAMAGE, WHETHER DIRECT OR INDIRECT, arising out of or in connection with the Free
version, the Plugin, a Trial, an Education License or a Beta License, this License as it
applies to them, the Third-Party Components, the Results or Exported Documents, or the use of
or inability to use any of them, whether the claim is based on contract, tort (including
ordinary negligence), product liability, statute or any other legal ground, and even if the
Licensor was advised of the possibility of such loss. This includes in particular:
(a) loss of profit, revenue, contracts, savings, goodwill or business opportunities;
(b) loss or corruption of data or files, and the cost of restoring them;
(c) business interruption and downtime;
(d) project delays, penalties and liquidated damages;
(e) the cost of redesign, rework, repair, replacement or remedial work on designs,
installations or equipment;
(f) claims by third parties, including your clients, employer, building owners, contractors
and authorities; and
(g) indirect, consequential, incidental and special loss.
21.2 If, despite Section 21.1, the Licensor is held liable, its total aggregate liability for all
claims arising out of or in connection with the Free version, the Plugin, a Trial, an
Education License or a Beta License shall not exceed DKK 500 (five hundred Danish kroner).
21.3 Sections 20, 21.1 and 21.2, and Sections 30 and 31, do not exclude or limit:
(a) liability for loss caused intentionally (forsæt) or by gross negligence (grov uagtsomhed)
on the part of the Licensor;
(b) liability for death or personal injury, to the extent that it cannot be excluded or
limited under Applicable Law;
(c) liability under mandatory product liability legislation, including the Danish Product
Liability Act (produktansvarsloven) and other national laws implementing Council
Directive 85/374/EEC or Directive (EU) 2024/2853; or
(d) any other liability or right that cannot be excluded or limited under Applicable Law,
including mandatory consumer rights.
21.4 The Free version, the Plugin, a Trial, an Education License and a Beta License are made
available free of charge. The exclusions and limitations in Sections 20 and 21 reflect this
and are an essential basis of this License; without them, the Licensor would not make them
available free of charge.
21.5 The exclusions and limitations in Sections 20, 21, 30 and 31 also apply in favour of the
Licensor's directors, employees, agents and subcontractors.
21.6 If you are a Consumer, Sections 10, 20, 21, 30 and 31 apply only to the extent permitted by
the mandatory consumer protection law that applies to you. Any part of them that is not
binding on you shall be disregarded, and the rest of this License continues to apply.

PART III — TRIAL, EDUCATION AND BETA LICENSE

22. TRIAL
22.1 A Trial lets you try the Pro Features of one Program free of charge for 30 days, counted
from the first start of the Pro version under the Trial. You start it in the Program after
signing in to your Account. No payment details are needed, and a Trial never turns into a
paid license by itself. The Licensor may extend a Trial, for example for a pilot project; the
new end date is then shown in the Program.
22.2 There is one Trial per computer and one per Account for each Program. A Trial stays on the
computer where it was started and does not move to another computer.
22.3 A Trial works only if the Program can connect to the Licensor's servers when it starts;
without a connection, the Program works as the Free version and says why. If the connection
is lost while you work, the Pro Features remain until you close the Program, but not beyond
the end of the Trial. For a closed network, an offline Trial may be agreed on request.
22.4 Every document, export and package for Autodesk Revit made under a Trial carries the mark
«Trial version — not for issue», in the language of the document. You may use a Trial to
evaluate the Software, also in your business, but you may not issue, deliver or submit
documents made under a Trial to clients, authorities, contractors or other third parties, use
them in paid work, or remove, cover or hide the mark.
22.5 At the end of the Trial the Program works as the Free version (Section 28). Your Project
Data, including the data of the Pro Features, is kept.
22.6 The Licensor may end a Trial that is misused, by notice to the Account; the Program then
works as the Free version.

23. EDUCATION LICENSE
23.1 Current students and members of the teaching staff of an educational institution can apply
for an Education License through the form at tools.cphhvacstudio.dk/education/. The Licensor
verifies their eligibility, for example by an institutional e-mail address or by a document
showing enrolment or employment, and may refuse an application.
23.2 An Education License gives one person one Seat for each Program for which it is granted, free
of charge, for 12 months. It can be renewed by a new application. Seats under Education
Licenses may not be pooled or shared between persons.
23.3 An Education License may be used only for teaching, learning and non-commercial research. It
may not be used for paid work, for work for clients or employers, or for any other commercial
purpose.
23.4 Every document, export and package for Autodesk Revit made under an Education License carries
the mark «Education — not for issue», in the language of the document. You may hand in such
documents in your studies and use them in teaching and non-commercial research, but you may
not issue them as documents of a project to clients, authorities, contractors or other third
parties, or remove, cover or hide the mark.
23.5 The Licensor may at any time verify that the conditions of this Section 23 are met. It may
revoke an Education License by notice to the Account if it is misused, if its holder is no
longer eligible or if the application was not correct; the Program then works as the Free
version.
23.6 When an Education License ends, the Program works as the Free version (Section 28). Your
Project Data is kept.

24. BETA LICENSE; WARRANTY AND LIABILITY UNDER PART III
24.1 The Licensor may give a Beta License to a person who tests the Software (a beta tester): one
Seat for each Program named, free of charge, for the term that the Licensor sets and the
Account shows. The Licensor gives it in the Account or with a promotional code that the
person enters in the Account.
24.2 A Beta License may be used for any lawful purpose, including commercial work. Documents,
exports and packages for Autodesk Revit made under it carry no mark. A Seat under a Beta
License is for the person to whom it is given and may not be shared.
24.3 When the term of a Beta License ends, the Program works as the Free version (Section 28).
Your Project Data, including the data of the Pro Features, is kept.
24.4 A Trial, an Education License and a Beta License are provided free of charge, and Sections 20
and 21 apply to them.
24.5 Section 26 applies to a Seat under an Education License or a Beta License.

PART IV — PRO LICENSE

25. PRO LICENSE
25.1 A Pro License is bought as a yearly subscription for one or more Seats under the Terms of
Service, through the Licensor's reseller Paddle.com, the Merchant of Record for all orders.
Prices, payment, taxes, renewal, cancellation, a Consumer's early termination and refunds are
governed by the Terms of Service.
25.2 Subject to a valid Seat and compliance with this License, the Licensor grants the User a
non-exclusive, non-transferable right to use the Pro Features of the licensed Program, or,
for "All programs", of every Program of the Product Line, on one computer at a time during
the License Term, for any lawful purpose including commercial work. Without a valid Seat the
Program works as the Free version (Section 28).
25.3 A Seat is bought by the Customer from Paddle, the Licensor's reseller and Merchant of Record,
and assigned to one User in the Customer's Account. The Customer may reassign a Seat as
described in the Terms of Service and in Section 29. Each User accepts this License
individually; the Customer is responsible for its Users' compliance.
25.4 The User may install the Software on any number of computers that he or she uses, but under
one Seat the Pro Features of a Program run on one computer at a time (Section 26).
25.5 After payment, the Seat appears in the Account of the Customer. The Program obtains the Pro
version as an update after the User signs in with the Account that holds the Seat, or the
Account offers the Pro Installer.
25.6 The Pro Installer, the Pro version that a Program downloads and Offline Activation files are
for the User of the Seat only and may not be passed on to others.

26. LICENSE SERVICE, ONE COMPUTER AT A TIME AND OFFLINE ACTIVATION
26.1 The Pro Features are enabled through the License Service. Under one Seat, the Pro Features of
a Program run on one computer at a time. When you start the Program on another computer, the
Pro Features move there and the previous computer works as the Free version; no Project Data
is lost. To prevent misuse, the number of such moves per day is limited. The details are
described at tools.cphhvacstudio.dk/licensing/.
26.2 The Program checks the License with the License Service when it is online, about once an hour
while it runs. Without a connection, the Pro Features keep working for 7 days after the last
successful check; after that, the Program works as the Free version until it can check again.
The Program never locks your Project Data.
26.3 For a computer in a closed network or without a connection to the internet, the Customer's
Account issues an Offline Activation bound to that computer. A Seat used through an Offline
Activation is not used online at the same time. An Offline Activation is valid until the
Valid Until date of the Seat — for a Seat whose subscription renews automatically, for 21
more days after it, so that the computer does not fall back to the Free version on the day of
the renewal; one issued while a refund of the purchase is still possible is valid only for a
limited time, after which the Account issues one for the rest of the License Term.
26.4 An Offline Activation can be moved to another computer through the Account a limited number
of times a year. Before it is moved, you must delete the license file on the old computer and
confirm this in the Account. Using a license file after it has been replaced is a breach of
this License.
26.5 You may not share a Seat between several persons, use the Pro Features under one Seat on more
computers at the same time than this Section allows, or circumvent these limits by technical
means, such as copying sessions, license files or images of computers.

27. UPDATES AND SUPPORT PERIOD
27.1 While the License is valid, the User receives every update of each Program covered by the
Seat: updates lead to the Latest Version, whose Free and Pro builds are released together. A
renewal moves the Valid Until date to the end of the new License Term.
27.2 When the License has ended, the Program receives updates as the Free version: an update
installs the Latest Version as the Free version and removes the Pro module, which the Program
no longer loads, and the Program says so before it installs the update.
27.3 During the Support Period of a Program (Section 9.2), the Licensor provides security updates
in its Latest Version to everyone: as the Free version, and with the Pro Features to Users
whose License is valid.

28. WHEN A LICENSE ENDS
28.1 The Pro Features are available only while a License for them is valid. When a License ends —
at the end of the License Term without renewal, after a refund, on a Consumer's early
termination under the Terms of Service, on termination for breach, or at the end of a Trial,
an Education License or a Beta License, also one used through an Offline Activation — the
Program works as the Free version. No version of a Program remains in Pro after the License
has ended.
28.2 Your Project Data is kept, and the Free version opens every project. The data of the Pro
Features in it are kept as read and are read-only in the Free version: it does not change,
delete or recalculate them, shows that Pro is needed in place of their figures when the data
on which they depend have changed, and refuses an action that would change, delete or break
them. The Free version saves them unchanged. With a valid License they work again.
28.3 Exported Documents made while the License was valid may still be used, subject to Section 7.3
and to the marks and purposes of Part III.
28.4 If the Licensor discontinues the License Service or the Program, it will first release a
perpetual unlock of all paid versions of the Programs, so that they work in Pro without the
Licensor's servers.
28.5 Deleting the Account ends access to the Pro Features through the License Service.

29. SEATS OF A CUSTOMER AND TRANSFER
29.1 A Customer that buys several Seats holds them in its Account, and one Seat is assigned to the
buyer at the purchase. The Customer assigns the other Seats in the Account to Users, such as
its employees or contractors, and can take a Seat back and assign it to another person,
within the limits shown in the Account.
29.2 The Customer is responsible for the use of its Seats by the Users to whom it assigns them. It
must have a legal basis for giving the Licensor their e-mail addresses and inform them
(Section 35.3). Each User accepts this License when he or she uses the Software.
29.3 When a Seat is taken back or transferred to another person, the previous User's right to use
the Pro Features under that Seat ends, and the previous User must delete the Pro version and
any Offline Activation of that Seat. A Seat used through an Offline Activation is transferred
only after confirmation in the Account that the old license file has been deleted.
29.4 A Seat may be transferred to another person or organisation only through the transfer
procedure of the Account, which ends the transferor's rights under the Seat and requires the
transferor to confirm that its copies of the Pro version and its Offline Activations of that
Seat have been deleted. A User who holds a Seat from his or her own purchase, for example
after selling the license or changing jobs, asks the Licensor for such a transfer. A transfer
on request applies to the end of the paid License Term: the renewal of the Seat is cancelled,
and the new holder continues after that with a purchase of his or her own. This procedure is
how the Licensor gives effect to any right the Customer may have under mandatory law to pass
on a copy it has paid for.

30. WARRANTY (PRO LICENSE)
30.1 If the User is a Consumer, the mandatory rules of the Consumer's country of residence on the
conformity of digital content and digital services and on updates (in Denmark: købeloven §§
75 a ff.) apply to the Pro Features and are not limited by this License.
30.2 If you are a Business User, the Licensor will, during the License Term, use reasonable
efforts to correct in a later version any reproducible error that you report and that makes
the Pro Features deviate materially from their documentation. If the Licensor does not
correct such an error within a reasonable time, you may end the affected Seats by notice and
receive a refund of the fees paid for the remaining full months of the License Term. Apart
from this, and to the maximum extent permitted by Applicable Law, Section 20.1 applies to the
Pro Features for Business Users.
30.3 Section 8 applies in full. The Licensor does not warrant that the Results will meet your
requirements or comply with any standard, code or regulation.

31. LIMITATION OF LIABILITY (PRO LICENSE)
31.1 TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE LICENSOR SHALL NOT BE LIABLE FOR
INDIRECT OR CONSEQUENTIAL LOSS arising out of or in connection with a Pro License, the
Software used under it, the License Service, the Results or Exported Documents, whether the
claim is based on contract, tort (including ordinary negligence), product liability, statute
or any other legal ground, including in particular the losses listed in Section 21.1(a) to
(g).
31.2 THE LICENSOR'S TOTAL AGGREGATE LIABILITY for all claims arising out of or in connection with
a Pro License, the Software used under it, the License Service and the Results shall not
exceed the higher of (a) the fees paid for the affected Seat or Seats in the 12 months before
the event that gave rise to the first claim and (b) the price, at the time of that event, of
one annual Pro License for one Seat of the kind concerned (one Program or "All programs").
31.3 Sections 31.1 and 31.2 are subject to the exceptions in Section 21.3. Sections 21.5 and 21.6
apply; Section 21.4 does not apply to a Pro License.

32. END OF A PRO LICENSE
32.1 A Pro License ends at the end of the paid License Term if its subscription has been
cancelled; earlier, where the Terms of Service so provide, after a refund or on a Consumer's
early termination; or when the Licensor terminates it for breach (Section 32.2). If the
payment for a renewal fails, the Pro License continues while Paddle retries the payment, and
it ends when Paddle finally cancels the subscription, at the latest 30 days after the end of
the paid License Term.
32.2 The Licensor may terminate a Pro License if the Customer or the User materially breaches this
License and does not cure the breach within 14 days after notice, or with immediate effect
for a breach of Section 3, 7.3 or 19 that cannot be cured. On termination for breach the
License Term ends without refund. For Consumers this Section applies only to the extent
permitted by mandatory law.
32.3 When a Pro License ends, the Program works as the Free version (Section 28).

PART V — PRIVACY AND CONNECTIONS

33. WHEN THE SOFTWARE CONNECTS
33.1 Without a License for it (Section 1.6), a Program connects to the Licensor's servers only:
(a) to check for updates, at most once in 7 days when it starts and whenever you choose Check
for updates…; the request names only the Program, and you can switch the regular check
off in the settings of the Program; and
(b) when you act yourself: signing in, opening Account & license, starting a Trial,
downloading the Pro version or sending a problem report.
33.2 With a License for it, the Program also connects when it starts and about once an hour while
it runs, to check the License and to move the Pro Features between computers (Section 26).
33.3 The Plugin connects only to check for updates; the request names only the Plugin, and you can
switch the check off.
33.4 A problem report is sent only when you send it, with your consent each time, and you see what
it contains before it is sent. Automatic crash reports are sent only if you switch them on,
contain technical data only and can be switched off at any time.
33.5 An Offline Activation works without any connection until it ends.

34. WHAT THE SOFTWARE SENDS
34.1 When you sign in: the e-mail address of your Account, to which a sign-in code is sent.
34.2 With the license checks and the requests of Section 33.1(b): an identifier of the session of
your Account on that computer, signed with a key that stays on that computer, the License, a
hash of the computer's identifier (not the identifier itself), the Device Label that you
chose for the computer, the Program and its version, and whether the Pro version is
installed. The Software does not send the Windows name of the computer.
34.3 The Software does not send Project Data, Results or Exported Documents, except a project file
that you choose to attach to a problem report. It contains no advertising and no usage
analytics.

35. PERSONAL DATA
35.1 CPH HVAC Studio ApS is the controller of the personal data processed through the Software and
the Account. The privacy policy at tools.cphhvacstudio.dk/privacy/, to which the Programs
link before the first sign-in, describes the data, the purposes, the legal bases, how long
the data are kept, the processors and your rights.
35.2 Personal data that you enter into the Software, such as names or contact details in projects
and reports, stays where you save it. You are responsible for that processing under
applicable data protection law.
35.3 A Customer that assigns a Seat gives the Licensor the e-mail address of the person concerned.
It must have a legal basis for this and inform the person; the Licensor also informs the
person in its invitation e-mail.
35.4 Choose a Device Label that identifies the computer for you without containing more personal
data than you need, for example "Office laptop" rather than your full name.

End of License.
