Terms of use
Effective from 18 September 2026.
These terms govern the use of Kalkulix.eu, operated by BOS group s. r. o., Karpatské námestie 10A, 831 06 Bratislava, Slovakia, company ID 54948151 (“we”). All services on the website are free for visitors.
Calculators and content
The calculators, scores, recommendations and articles are for information only. Results are indicative estimates based on the data you enter and on the public sources and assumptions stated for each tool. They do not replace professional, technical, tax, payroll or financial advice, or a binding quote from a supplier.
Any decision about an investment, a contract or any other step is always yours. We aim to keep the data correct and up to date, but we do not guarantee that it is complete or that the actual outcome will match the calculation.
Quote requests
On the Slovak, Czech and Hungarian versions of the website you can request a non-binding quote for solar panels or a heat pump. By sending the form with your consent you ask us to pass your details to a partner installation company, which will contact you with a quote.
The quote is prepared by, and any supply contract is concluded directly with, the installation company that sent you the quote, on its terms. That company is responsible for the content of the quote, the price and the work. A request does not commit you to anything.
Review of an uploaded quote
By uploading a quote (PDF) you order our free automated review service. We extract data from the document automatically, possibly with the help of an artificial intelligence service; always check and correct the pre-filled fields before evaluating. The result is an indicative comparison with usual market values, not an expert opinion or a rating of the supplier.
Only upload documents that you received or are entitled to use. We do not store the document; details are in the privacy policy.
Sending a calculation by e-mail
On some pages you can have a summary of a calculation sent to the e-mail address you provide. We send tips and news only if you asked for them separately; you can unsubscribe at any time.
Installation company registration
By registering, a company applies to be included in the partner list. There is no legal entitlement to inclusion; the terms of cooperation, in particular the passing on of requests, are agreed in a separate contract.
Proper use of the website
Do not use the website in a way that would disrupt its operation, circumvent the protection of the forms, automatically collect its content on a large scale, or submit other people's or false data in the forms. Embedding a calculator on another website is governed by separate embedding terms.
Liability
We are liable for damage caused by the use of indicative results only to the extent that liability cannot be excluded by law. We do not guarantee uninterrupted availability of the website. These terms do not limit the rights you have as a consumer under the law.
Intellectual property
The texts, calculation models, graphics and design of the website are protected by copyright. They may not be copied or redistributed without our consent beyond ordinary personal use and quotation with attribution.
Data protection
How we process personal data is explained in the privacy policy and the cookie policy, both linked in the website footer.
Final provisions
These terms are governed by the law of the Slovak Republic; if you are a consumer, this does not affect the protection afforded to you by the mandatory provisions of the law of your country of habitual residence. We may change these terms, in particular when our services change; the new version applies from its publication on this page. Please send questions and complaints to info@kalkulix.eu.
