General
These terms govern use of the websites operated by Holon Puzzle – Tomasz Karczewski (Südstraße 31, 47475 Kamp-Lintfort, Germany), in particular Element Guru (https://element.guru/) and Holon Puzzle (https://holonpuzzle.com/).
By using the services you accept these terms.
The services are available to all users. For users under 16, use of interactive features (e.g. contact forms) requires consent from a parent or legal guardian.
Services offered
The operator provides free educational and informational content (articles, video, podcasts).
Affiliate links may be shown (e.g. to taniaksiazka.pl). Purchasing via such a link does not increase the price you pay.
Specialist services such as ghostwriting or music services (e.g. presented on https://kot.ist/) are not part of the standard website services and are governed by separate agreements or quotes. For minors, contracts must be concluded by a legal guardian.
Features such as user accounts and subscriptions are under development and not publicly available.
Copyright and intellectual property
Unless stated otherwise, texts, music and graphics are owned by Holon Puzzle – Tomasz Karczewski.
Quoting short excerpts is permitted only with an active link to the source (e.g. https://element.guru/).
Copying or commercial use without written permission is prohibited.
Liability
Content is educational and subjective; it does not constitute psychological, medical or legal advice.
The operator is not liable for decisions you make after reading the content.
The operator is not liable for third-party sites linked from the service (e.g. YouTube, affiliate partners).
Final provisions
Unless otherwise stated, German law (BGB) and EU consumer protection rules apply.
Disputes with businesses are subject to the courts at the operator’s seat (Germany).
Consumers may bring claims in their country of residence.
Information on the EU ODR platform is provided in the Legal notice section (https://element.guru/impressum/).
Automatic translations and liability
Language versions other than Polish may be generated automatically using external translation tools. The process includes sending content to a translation provider, receiving the result, and publishing it in the service.
Automatic translations may contain errors, simplifications, or inaccuracies. I am not liable for consequences resulting from relying solely on an automatically translated language version.
The Polish version is the reference and governing version. If translation quality is insufficient, you may use your own browser translator, noting that such tools may transfer data outside the service and beyond my control.
