Terms of Use

PlannAir application and website · Version 1.0 · Effective from: 1 August 2026

These terms describe what the use of PlannAir entitles you to, what we expect from you, and who is responsible for what. The most important thing first: PlannAir is a design aid — the professional checking of the calculated dimensions and of the export sent for manufacture remains your task. Section 9 is about this.

1. Who these terms apply to

These terms are concluded between AeroTech Services Kft. (hereinafter: we, our details are in the imprint) and the user of the PlannAir application or of the plannair.hu website (hereinafter: you).

PlannAir is made for professional, business use. We do not provide the service to persons under the age of 16. If you use it on behalf of an organization (company), you warrant that you are entitled to bind the organization.

2. How the contract is concluded

The contract is concluded upon registration or — if your account was created by an organization — upon your first login, and is entered into for an indefinite period. The service cannot be used without accepting these terms.

3. What the service provides

PlannAir serves for the design of HVAC duct pieces: the parameterization and 3D display of duct pieces, organizing them into projects and groups, synchronization across devices, sharing within the organization, and exporting into manufacturer Excel templates.

The service is available in a browser and as a mobile application. The feature set is continuously developing; the introduction, modification or discontinuation of individual features is our decision, and we inform you of material changes in advance.

4. Account and access

  • The account is personal. The login credentials may not be handed over to anyone else, and their shared use is not permitted.
  • You are responsible for the security of your password and for everything that happens from your account. If you notice abuse, please report it without delay at security@plannair.hu.
  • The range of data and features visible in your account is determined by the permission you have been given in your organization.

5. The role of the organization, and the content

The projects, groups, duct pieces and exports form the content of the organization in which they were created — not ours and not that of the individual user. There is no content outside an organization: every project belongs to exactly one organization. The organization decides who may access it and with what permission.

It follows from this that after your account ceases to exist the content remains with the organization, and that in questions of access within your organization — who sees what, who may modify — you must turn to the competent administrator of the organization.

We access your content to the extent that the provision of the service, troubleshooting or the investigation of your enquiry makes it necessary. We produce aggregated, anonymous statistics with the safeguards described in the privacy policy.

6. Fees

The service is currently free of charge. If a subscription scheme is introduced, we will inform you of it in advance, with a reasonable notice period, and taking up the paid service always requires a separate decision on your part — an existing account does not automatically become a paid one.

7. What we expect from you

  • that you use the service lawfully and as intended;
  • that you do not attempt to circumvent the permission limits, to access the data of others, or to breach the security of the system;
  • that you do not load the service beyond the extent of intended use, and do not run automated bulk queries on it without our consent;
  • that you do not reverse-engineer, copy or incorporate into another product the application or parts of it;
  • that you do not upload infringing content, and that you warrant that you are entitled to use the data you enter.

8. Intellectual property

The PlannAir application and all its elements are our intellectual property. By accepting these terms you receive a limited, non-exclusive, non-transferable licence, revocable at any time, to use the service as intended — not ownership or any right going beyond that.

The content entered by you or by your organization remains yours or the organization’s. We acquire a licence to it only to the extent necessary for the provision of the service (storage, display, synchronization, backup).

9. Checking the design result

PlannAir is an aid, not a designer and not an expert. It calculates and exports from the parameters given, but it cannot judge whether the result is correct in the given building, in the given HVAC system.

It follows from this that you are responsible for ensuring that:

  • the dimensions, materials and parameters entered are correct and correspond to the actual construction situation;
  • the export forwarded for manufacture or for ordering is professionally checked before it is sent;
  • the applicable standards and the official and design requirements are complied with.

We accept no liability for manufacturing, financial or construction damage arising from incorrect data entry, from a failure to check, or from a change in the manufacturers’ templates in the meantime. The manufacturers’ article numbers, templates and conditions may change without our involvement as well.

10. Availability

We endeavour to keep the service continuously available, but we do not undertake guaranteed availability. An interruption may occur because of maintenance, bug fixing or the outage of an external provider; where possible we give advance notice of planned, longer outages.

The application can also be used offline; the local data is synchronized when the network returns. We recommend that you also save important exports to your own device.

11. Liability

We provide the service as is. To the extent permitted by law we are not liable for lost profit, data loss, a missed business opportunity, or indirect or consequential damage.

This limitation does not affect liability for breach of contract caused intentionally or damaging human life, bodily integrity or health, nor anything that the law excludes from limitation.

12. Data processing

We process your personal data in accordance with the privacy policy. If you use the service on behalf of an organization, we act as processor in respect of the organization’s content, within the framework of the data processing agreement concluded with the organization.

13. Termination of the contract

  • You may terminate the contract at any time, without giving reasons, by deleting your account. The deletion procedure is described in section 5 of the privacy policy.
  • Your organization may terminate your access if it was the one that provided your account.
  • We may terminate the contract or suspend access if you breach the terms seriously or repeatedly, or if the use endangers the security of the service or of other users. We inform you of this, and where it is proportionate we call on you beforehand to cease the infringement.

14. Amendment of these terms

We may amend these terms — for example because of a new feature or a change in the law. We notify you of the amendment in advance within the service or by e-mail. If you do not accept the amendment, you may terminate the contract by deleting your account.

15. The version installed from the App Store

If you downloaded the application from the Apple App Store, the following also apply:

  • this agreement is concluded between you and us only, and not between you and Apple; we alone are responsible for the application and its content;
  • Apple has no obligation whatsoever to furnish any maintenance or support services with respect to the application;
  • in the event of any failure of the application to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price to you; beyond this, to the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the application;
  • we, and not Apple, are responsible for claims relating to the application — including product liability, legal compliance and intellectual property claims;
  • you represent that you are not located in a country that is subject to a United States embargo, and that you are not listed on any United States list of prohibited or restricted parties;
  • Apple and its subsidiaries are third-party beneficiaries of these terms, and may enforce them against you.

16. Governing law and dispute resolution

Hungarian law governs the contract. We settle our disputes primarily by negotiation — please contact us at support@plannair.hu.

If you qualify as a consumer, you may turn with your complaint to the conciliation body competent for your place of residence, and you may use the online dispute resolution platform of the European Commission. This option remains available alongside the fact that you may also turn to the courts.
