Electronic services are free of charge. Using the Site does not require an account.

4. Technical requirements

To use the Site properly you need:

• a device with internet access,
• a current web browser supporting HTML5, CSS3 and JavaScript,
• cookies strictly necessary for the Site enabled,
• an active email address, if you use the forms.

The Provider draws attention to the risks inherent in using the internet, in particular malicious software and unauthorised access to data in transit. Using up-to-date security software is recommended.

5. Rules for using the Site

The User undertakes to use the Site in accordance with the law and good practice, respecting personal rights and the intellectual property of third parties. In particular, the following are prohibited:

• supplying unlawful content, including content infringing third-party rights,
• actions that disrupt the Site or place an unreasonable load on the infrastructure,
• attempts to gain unauthorised access to the Provider IT resources,
• circumventing security measures, including anti-bot protection,
• automated harvesting of Site content contrary to the rules in the robots.txt file,
• entering third-party personal data in the forms without a legal basis.

Where these rules are breached, the Provider may block access to the Site after first calling for the breach to stop, unless immediate action is necessary on security grounds.

6. Text and data mining

The Provider does not reserve the right to text and data mining within the meaning of Article 4(3) of Directive (EU) 2019/790 on copyright in the Digital Single Market. Content published on the Site may be automatically retrieved, indexed and analysed, including by search engines and by artificial intelligence assistants and agents, and may be used to train, fine-tune and validate machine learning models.

Access rules for crawlers are set out in the Site robots.txt file, and retrieval must not disrupt the Site (section 5). This provision does not transfer any rights in the Site content and does not permit its distribution beyond what the law allows (section 13).

7. Access to the Platform

The Site is informational and presents our offering. The Platform is not accessed through the Site; access requires a separate contract which sets out in particular:

• the functional scope and the number of assets covered,
• the deployment model (cloud or on-premise),
• the fees and how they are settled,
• availability parameters and technical support response times,
• the terms on which personal data processing is entrusted,
• the rules for ending the engagement and handing back data.

Information about the Platform published on the Site, including feature descriptions and price ranges, constitutes an invitation to treat within the meaning of Article 71 of the Polish Civil Code, not an offer.

8. Early access programme

The Provider may make the Platform available under a free pilot lasting 60 to 90 days. The terms of the pilot are:

• the scope is agreed individually before it starts,
• the pilot is free of charge and creates no obligation to enter into a paid contract,
• the pilot is not a production environment and may not carry full availability parameters,
• once the pilot ends, data entered by the customer is made available for export in an open format,
• moving to a paid contract requires a separate declaration by both parties.

9. Right of withdrawal

A Consumer, and a sole trader with consumer rights, who has concluded a distance contract may withdraw from it within 14 days without giving a reason, under the Polish Act of 30 May 2014 on consumer rights. The period runs from the day the contract is concluded.

It is enough to send the withdrawal notice before the deadline expires, to biuro@hydronexis.pl or to the registered address.

10. Complaints

Complaints about the Site and the electronic services may be submitted:

• by email to biuro@hydronexis.pl,
• in writing to the Provider registered address.

A complaint should describe the problem, the date it occurred and contact details for a reply. We handle complaints within 14 days of receipt and send our response to the address indicated within the same period.

Complaints concerning the Platform are handled under the procedure set out in the contract concluded with the customer.

11. Out-of-court dispute resolution

A Consumer may use out-of-court means of handling complaints and pursuing claims, in particular by:

• applying to a permanent consumer arbitration court at the regional Trade Inspection authority,
• asking the regional Trade Inspector to open mediation proceedings,
• seeking help from a district or municipal consumer ombudsman or a consumer organisation.

Details are available from the Polish Office of Competition and Consumer Protection at uokik.gov.pl. Use of these procedures is voluntary and requires the agreement of both parties.

12. Liability

The Provider takes due care to keep the Site working correctly and without disruption. The Site is provided free of charge and no guaranteed availability parameters apply to it. The Provider reserves the right to technical breaks and gives advance notice of longer planned outages.

The Provider is not liable for:

• interruptions caused by force majeure,
• malfunctions of the User devices, software or connection,
• the acts of telecommunications and hosting providers beyond the Provider control,
• the consequences of the User supplying incorrect data or the data of another person.

Content published on the Site, including the cost calculator results, is illustrative and informational. It does not constitute legal or technical advice, nor a commercial offer, and must not be the sole basis for investment decisions. The calculator uses only the values entered by the User and includes no industry data.

13. Intellectual property

Rights to the Site, its layout, content, trade marks, graphics and the Platform software belong to the Provider or to authorised third parties.

Using the Site does not transfer any rights to those assets. Use of the content is permitted within the limits of personal use and quotation under the Polish Act of 4 February 1994 on copyright and related rights, provided the source is credited.

Third-party trade marks named on the Site, in particular Aplisens and Google Cloud, belong to their owners and are used for information purposes only.

14. Personal data

The rules for processing personal data, including the purposes, legal bases, retention periods, recipients and data subject rights, are set out in a separate document: Privacy policy.

Where a contract for access to the Platform is concluded, the customer remains the controller of the data entered into the system and the Provider acts as a processor under a data processing agreement compliant with Article 28 GDPR.

15. Regulatory compliance

The Provider develops the Platform with cybersecurity and operational resilience requirements in mind, appropriate to the nature of the services and the legal status of the parties.

16. Changes to these terms

The Provider may amend these terms for valid reasons, in particular changes in the law, in the scope of services or in how the Site works.

Changes take effect on publication on the Site. Services already begun are governed by the previous wording. Users of continuous services are notified of changes by email at least 14 days in advance; no objection within that period constitutes acceptance.

17. Final provisions

• Matters not covered here are governed by Polish law, in particular the Civil Code, the Act on the provision of services by electronic means and the Act on consumer rights.
• The choice of Polish law does not deprive a Consumer of the protection of mandatory provisions of the law of their country of habitual residence (Article 6 of the Rome I Regulation).
• Disputes with a User who is not a Consumer are resolved by the court having jurisdiction over the Provider registered office.
• Disputes with a Consumer are resolved by the court determined under general rules.
• If any provision of these terms proves invalid, the remaining provisions stay in force.
