Trust and transparency
What you should know
The key information is presented below in a short, scannable format.
Service and provider
These terms cover the informational website, calculators, generators and guides made available at oblicznik.com. The service is operated as a personal project by Akhmas Meraj from Malaysia and is provided without an account or subscription. Electronic contact: contact@oblicznik.com. No public correspondence address is provided; this and the remaining terms require final legal review before production.
How the electronic service is supplied
A tool is used by opening its page, entering or selecting values and requesting a result. The service begins when the page is used and ends when the user leaves it. No minimum use period applies and no purchase is concluded through the current website.
Technical requirements and ending use
A current standards-compliant browser, JavaScript and an internet connection for the initial page load are normally required. Calculations then run in the browser unless a tool clearly states otherwise. Users can stop using a tool at any time by closing or leaving the page.
Prohibited use
The website must not be used to submit unlawful content, interfere with operation or security, bypass safeguards, automate abusive traffic, impersonate another person or infringe third-party rights. Do not enter another person’s sensitive or confidential data without a lawful reason.
Informational nature of results
Results are estimates produced from the values entered and the assumptions shown on the page. They are not an administrative decision, binding offer, diagnosis, or legal, tax, medical or investment advice. The user should confirm any decision with significant consequences using the cited official source or a qualified professional.
User responsibility
The user is responsible for checking input accuracy, choosing the correct applicable year and reading the stated assumptions, limitations and rounding rules. A correct formula can still produce an unsuitable answer when the facts fall outside its stated scope.
Availability and changes
Reasonable efforts are made to keep published tools available and current, but uninterrupted operation is not guaranteed. A tool may be corrected, updated, temporarily withdrawn or excluded from indexing when a material source, parameter or implementation needs verification.
Intellectual property and permitted use
Website text, interface design and original implementation may be protected by intellectual-property law. Ordinary personal use of published tools and sharing a link to a page are permitted. Copying the service, removing attribution from protected material or presenting its content as an official source is not permitted unless the applicable law or a separate licence allows it.
External links
External links are provided to help verify a rule or obtain further information. The linked authority or third party controls its own content, availability and privacy practices; a link does not transfer responsibility for that external service to this website.
Complaints and applicable law
A service complaint should identify the affected page, date, device or browser, the problem and the expected outcome, without unnecessary personal data. Complaints and corrections follow the contact and corrections pages. These terms are interpreted under Polish law, without limiting mandatory rights that apply to a consumer.
