1. Identification of the owner
This website, the desktop application, the mobile application and the service as a whole (hereinafter, «Zetein» or «the Service») are operated and provided by Hefiris SW Sociedad Limitada, Tax ID B93857498, with registered office at Calle Hernández Lázaro 34, 6.º B — 46015 Valencia, registered at the Commercial Registry of Valencia, Sheet V-236812 (hereinafter, «the Owner»).
Under an exclusive assignment agreement entered into with the author of the program, Hefiris SW Sociedad Limitada holds the exploitation rights over Zetein in all its versions and forms, including the power to grant licences and sub-licences of use, and is the only entity entitled to commercialise it.
2. Purpose
Zetein is an operational coordination platform for companies in the construction and installation sector, enabling them to manage the tracking of works, work reports, documentation, communications and progress on their sites, keeping a complete record of activity. These conditions govern access to and use of the Service by contracting companies and by the users they authorise.
3. Acceptance
Registering with Zetein and using the Service imply full and unreserved acceptance of these Terms and Conditions, of the Privacy Policy and, where applicable, of the Data Processing Agreement. If the user does not agree with their content, they must refrain from using the Service.
The person registering a company declares that they have sufficient authority to contractually bind that company.
4. Contracting, renewal and cancellation
Zetein offers different access arrangements, including periodic subscription plans and tailored rates for certain profiles. Subscription plans allow up to 49 users per company; a larger number of users or adaptations of the Service are contracted under the Enterprise rate, agreed individually. The features and prices in force shall be those published during the registration process or those individually agreed.
The Owner may offer, at its discretion, free trial periods to certain profiles. Where offered, such periods shall be of limited duration and shall not require a means of payment; if they end without a plan being contracted, access may be suspended.
Subscription plans renew automatically for equivalent periods (monthly or annual) calculated from the date of contracting, and not by calendar months: if the contract is entered into, for example, on the 13th, each billing period will run from the 13th to the 13th.
Cancellation of the monthly plan. The customer may cancel at any time from the platform, with no minimum notice. Cancellation takes effect at the end of the current billing period, with the customer retaining access to the Service until that date. No refund of the period already paid shall apply.
Cancellation of the annual plan. The annual plan renews on expiry unless the customer gives notice of its intention not to renew at least thirty (30) days before the renewal date. Non-renewal notified within that period takes effect at the end of the current annual term, with the customer retaining access until that date. No refund of periods already paid shall apply.
The Owner reserves the right to modify prices and plans, giving reasonable prior notice. Modifications shall not affect periods already paid for.
5. Conditions of use of the Service
The customer and its authorised users undertake to use the Service diligently and in accordance with the law, and in particular to:
- Use Zetein exclusively for the professional purposes of managing their own works.
- Not enter third-party data without an adequate legal basis for doing so.
- Securely safeguard their access credentials and the company encryption key (see clause 7).
- Not use the Service in any way that compromises its security, availability or integrity.
6. Intellectual and industrial property
All intellectual and industrial property rights over Zetein —including, without limitation, its source code, object code, architecture, databases, design, interfaces, structure, operating logic, documentation, trade marks, names and logos— belong exclusively to its author or to the Owner as set out in clause 1, and are exploited exclusively by the Owner. All rights are reserved.
Contracting the Service grants the customer only a personal, limited, revocable, non-exclusive and non-transferable right of use, for the duration of the contractual relationship and for the purposes set out in these conditions. It does not entail any assignment or transfer of intellectual or industrial property rights.
7. Restricted distribution and prohibition of copying
7.1. Distribution limited to the customer’s organisation
Zetein is NOT distributed through public app stores. Access to the desktop and mobile applications is provided in a controlled manner and exclusively to the contracting company and to the users it authorises within its own organisation and chain of work (management, supervisors, site personnel and subcontractors invited through the Service itself).
It is strictly prohibited to disseminate, distribute, assign, sublicense, lend, rent, publish, make available to third parties or otherwise provide access to the applications, installers or files of the Service outside the scope of the contracting company, save with the Owner’s express written authorisation.
7.2. Prohibition of reverse engineering and copying
The following are expressly prohibited, in whole or in part:
- Decompiling, disassembling or reverse engineering the Service, as well as attempting to access, derive or obtain its source code, algorithms or structure, except in cases mandatorily permitted by law.
- Reproducing, copying, adapting, modifying, translating or creating derivative works of the Service.
- Developing, marketing or making available products or services that reproduce, imitate or are based, wholly or partly, on Zetein.
- Removing, altering or concealing proprietary notices, watermarks, licence identifiers or any traceability element incorporated into the Service.
7.3. Consequences of breach
Breach of the prohibitions in this clause constitutes a serious infringement of the Owner’s intellectual and industrial property and of this contractual relationship, and shall entitle the Owner to:
- Immediately suspend or cancel access to the Service without refund.
- Claim compensation for all damages caused, including loss of profit and consequential loss.
- Claim a contractual penalty of 50,000 euros for each proven infringement, without prejudice to compensation for greater damages that may apply.
- Bring such civil and criminal actions as may be appropriate in law, including those provided for the protection of intellectual and industrial property and trade secrets.
8. Customisation of the Service
The Owner may offer the customer, at the latter’s request, the customisation of the Service’s applications (such as branding adjustments, labels, configuration parameters or visual elements) to adapt them to the needs of its organisation, provided that such customisations do not entail structural modifications to the code or to the architecture of the Service. Customisations requiring structural changes fall outside the scope of this clause and shall, where applicable, be the subject of a separate quotation and agreement.
Contracting a customisation entails a minimum commitment of twelve (12) months from its activation. During that period the customer shall maintain the subscription to the Service associated with the customisation; early termination shall not give rise to a refund of amounts already paid, nor shall it release the customer from paying the instalments outstanding until the committed period is completed.
Customisations are made to the Service, exploited exclusively by Hefiris SW Sociedad Limitada, and do not alter the intellectual and industrial property regime established in clauses 6 and 7: the customer acquires no right over the code, the architecture or the resulting developments, which are subject to the ownership and exploitation regime set out in clause 1.
9. Availability of the Service
The Owner shall endeavour to keep the Service continuously available, but does not guarantee the total absence of interruptions, in particular those arising from maintenance, force majeure or causes beyond its control. The Owner may carry out maintenance tasks that temporarily affect availability, seeking to minimise their impact.
10. Limitation of liability
The Service is provided as a tool to support site management. The truthfulness, accuracy and lawfulness of the data and content entered into Zetein are entirely the responsibility of the contracting company and its users. The Owner is not liable for decisions taken by the customer on the basis of the information managed on the platform.
To the maximum extent permitted by law, the Owner’s liability towards the customer shall be limited to the amount actually paid by the latter in the twelve months preceding the event giving rise to liability. The Owner shall not be liable for indirect damages, loss of profit or loss of data attributable to incorrect use of the Service by the customer.
Given the end-to-end encrypted nature of the Service (see Privacy Policy), the customer acknowledges and accepts that the loss of the company encryption key and of the associated credentials may irreversibly prevent the recovery of the data, without this giving rise to any liability for the Owner.
11. Suspension and cancellation
The Owner may suspend or cancel access to the Service in the event of non-payment, breach of these conditions or fraudulent or unlawful use. The customer may cancel its subscription from the platform in accordance with clause 4 for each type of plan, with no refund of periods already paid.
12. Modification of the conditions
The Owner may modify these Terms and Conditions to adapt them to legal, technical or business changes. Modifications shall be communicated to customers with reasonable prior notice, and continued use of the Service after they come into force shall imply their acceptance.
13. Continuity of the Service in the event of total cessation of activity
13.1. Scope
This clause applies solely and exclusively in the event of the total and definitive cessation of the activity of Hefiris SW Sociedad Limitada that entails the closure of the Zetein service. It shall NOT apply in the event of sale, merger, spin-off, assignment or any other form of transfer, whether total or partial, of the company, the brand or the Service to a third party: the existence of a transfer in itself excludes the right to migration provided for in this clause, regardless of the decisions the acquirer may subsequently take regarding the Service. In such cases, the acquirer shall be subrogated to the Owner’s position, and any subsequent modification of the conditions shall be governed by clause 12.
13.2. Continuity commitment
In the above scenario, the Owner shall, in addition to facilitating the full export of the data in accordance with these conditions and the Data Processing Agreement, carry out together with the customer, free of charge as regards the migration work, the migration of the Service to server infrastructure provided and paid for by the customer, so that it may continue using Zetein for its internal use.
13.3. Extent
The migration comprises the installation and commissioning of the Service on the infrastructure designated by the customer and the transfer of its data. The infrastructure, third-party licences and subsequent maintenance shall be at the customer’s expense. The commitment covers a single migration per customer, which must be requested within the period indicated in the cessation notice, which shall not be less than sixty (60) days from that notice.
13.4. Continuity licence
By way of exception to clauses 6 and 7, in this scenario (13.1) the Owner shall grant the customer a non-exclusive, non-transferable internal-use licence over the components of the Service necessary for its operation on the customer’s infrastructure. This licence does not include delivery of the source code, does not authorise redistribution, marketing or making the Service available to third parties, and does not entail any assignment of intellectual or industrial property rights.
The licence is granted on an irrevocable basis and shall remain in force even if the Owner ceases to operate the Service or is wound up.
13.5. Subsequent provision
Once the migration has been completed, the Service shall be deemed delivered «as is», with no subsequent obligation of support, maintenance, updating or warranty on the part of the Owner.
14. Applicable law and jurisdiction
These conditions are governed by Spanish law. For the resolution of any dispute, the parties submit to the Courts and Tribunals of Valencia (Spain), expressly waiving any other jurisdiction that may correspond to them, unless consumer legislation imposes a different jurisdiction where applicable.
