The website at oblicznik.com is operated by Akhmas Meraj as a personal project from Malaysia. Email contact@oblicznik.com about calculation errors, outdated official sources, translation problems, accessibility barriers, privacy or security concerns, or responsible partnership enquiries.
Reporting a calculation problem
For a calculation problem, include the exact page address, the applicable year, the smallest set of example inputs needed to reproduce the issue, the actual result and the result you expected. If a rule or parameter may have changed, link to the relevant public authority or legislation.
Content, translation and source corrections
For a content or translation correction, quote the short passage concerned and explain what is inaccurate or unclear. A link to a primary Polish source is especially helpful for legal, tax, employment, education and public-administration information.
Accessibility barriers
For an accessibility report, identify the page, browser or device, assistive technology if relevant, the task you were trying to complete and the barrier you encountered. If possible, say what alternative format or route would let you access the same information.
Privacy and security concerns
For privacy or security concerns, email contact@oblicznik.com and describe the affected page and observed behaviour without sending exploit code, credentials or another person’s data.
Commercial and editorial enquiries
For advertising, affiliate or editorial collaboration enquiries, describe the organisation, proposed relationship and any compensation or editorial conditions. Payment never buys a calculator result, formula change, favourable review or hidden placement.
Protect personal and confidential data
Do not send PESEL or identity-document numbers, tax identifiers, passwords, payment details, medical records or full datasets. Use fictional or minimised examples. Reports sent to contact@oblicznik.com are handled according to the corrections and privacy policies.
