§3 Technical requirements

Using the Service requires: a device with internet access, an up-to-date web browser with JavaScript and cookies enabled, and an active e-mail address (required for registration and communication).

§4 Nature of the service and professional responsibility

The Service is a calculation and design tool that supports the work of professionals. OZC (heat load) calculations are performed in accordance with the PN-EN 12831-1 standard, based on the input data entered by the User.

The User bears full professional responsibility for the correctness of the input data, the verification of results, and their use in designs and installations. The Service supports, but does not replace, the User's professional knowledge and judgment.

The Provider is not liable for the consequences of design and construction decisions made on the basis of results obtained in the Service, in particular where the input data were incomplete or did not reflect the actual condition of the building. This exclusion does not apply to damage caused by the Provider intentionally.

§5 Registration and account

An Account is registered by providing an e-mail address and password or by authenticating with a Google account. Registration with an e-mail address requires its verification.

The User is obliged to keep their login credentials confidential and to notify the Provider without delay of any suspected unauthorized access to the Account.

§6 Trial period and fees

Every newly registered Account receives a fourteen-day free Trial period with full access to the Service's features.

After the Trial period ends, the Account switches to read-only mode: the User retains access to their projects and the ability to export completed work (including PDFs), while creating and editing projects requires Account activation.

Account activation takes place on the basis of an individually agreed offer. Payment is made by invoice issued by the Provider. The Service does not charge payments automatically.

§7 Data entered by the User

The User may enter into the Service data concerning their clients and their projects (e.g. the investor's contact details, the project site address, building parameters). The User declares that they are authorized to process such data and remains its controller within the meaning of the GDPR; the Provider processes it solely for the purpose of providing the service. Details are set out in the Privacy Policy.

The User is prohibited from supplying content of an unlawful nature, including data that infringes the rights of third parties.

§8 Intellectual property

The Service, including its code, interface, selection algorithms, and materials, is the property of the Provider. Deliverables generated by the User on the basis of the data they have entered (reports, designs, PDF files) may be used by the User without restriction as part of their professional activity.

§9 Complaints

Complaints regarding the operation of the Service may be submitted to [email protected]. The Provider handles complaints within 14 days of receipt.

§10 Termination

The User may stop using the Service at any time and request deletion of their Account by contacting the Provider. The Provider may terminate the agreement and block the Account in the event of a gross breach of these terms, in particular attempts to compromise the security of the Service or use of the Service contrary to its intended purpose.

The rules for storing and deleting data after termination of the agreement are set out in the Privacy Policy.

§11 Amendments to the terms and final provisions

The Provider may amend these terms for important reasons (changes in law, changes to the Service's functionality). Users will be notified of amendments at least fourteen days in advance by e-mail or by a notice in the Service. A User who does not accept the changes may terminate the agreement before they take effect.

Matters not regulated herein are governed by Polish law. Disputes shall be resolved by the court having jurisdiction over the Provider's registered office, subject to mandatory provisions of law.
