Editorial Policy

This policy explains how Calc Tani creates, reviews, and corrects its calculators and explanatory articles. It is published so readers can understand both the basis for the numbers and how the content was produced.

Effective and last updated: 2026-09-20

1. Publisher and Responsibility

Calc Tani calculators and articles are maintained by the operator under the pseudonym Jeokjeongin (적정인). The operator is a software developer and remains ultimately responsible for publication and corrections. See the About page for more information about the operator and site.

Calc Tani is not a tax, legal, medical, or financial advisory practice. Its content and results are reference information intended to support understanding and comparison. For filings, contracts, diagnoses, investments, or other consequential decisions, verify the responsible authority's materials and consult an appropriately qualified professional.

2. What We Publish

We publish tools for recurring everyday and workplace calculations, plus explanations and examples needed to understand their results.
Where applicable, we provide the reference date, core formula, material assumptions, and exclusions rather than presenting a number without context.
We distinguish facts from examples and estimates, and our policy is not to publish unsupported claims or repetitive pages created only to attract search traffic.

3. Sources and Verification

For information that directly affects a result—such as tax rates, insurance rates, statutory formulas, and base rates—we prioritize primary sources: legislation, notices and guidance from the responsible public body, and official APIs. The Methodology records each calculator's core formula, source links, and effective date. Secondary sources may provide context but do not replace the official basis.

Before publishing a new tool or a material change, we compare the relevant formula and rate with its source, test representative inputs and boundary values, and check that the explanation matches the output. Because responsible authorities can change documents and URLs, we re-check when a link breaks or a new rule is announced.

4. Automation and AI Assistance

Automation or AI-assisted tools may be used for first drafts, Korean–English translation, copy editing, coding assistance, test-case generation, and repeated checks. Their output is not published automatically. Before publication, the operator reviews and revises it, checking the relevant sources, material facts, formulas, representative results, and translated meaning. The operator remains responsible for the final content.

5. Updates and Corrections

We review affected code and explanations when an official rate, law, or public dataset changes; when we identify a calculation error, omission, or potentially misleading passage; or when a reader submits a supported concern. Once verified, we correct the affected calculation and explanation and update the relevant reference or modification date for material changes. Content that can no longer be supported is revised or removed rather than left as a definitive claim.

To report an error, use the Contact page and include the page URL, the inputs used (excluding personal data), the actual and expected results, and any primary source you consulted. We verify the source and reproduce the issue before making a change; sensitive personal information is not needed.

6. Advertising Independence

Display advertising helps cover site operating costs, but advertisers and ad performance do not determine formulas, source selection, conclusions, or whether an error is corrected. Clicking an ad is never a condition for using a calculator or viewing its result, and advertising is not presented as an operator-written explanation or recommendation. If sponsorship or an affiliate relationship becomes relevant to content in the future, that relationship will be clearly disclosed on the affected page.

7. Bilingual Content

Korean and English pages are reviewed to convey the same material information and limitations. If wording differs or an interpretation is unclear, check the linked primary source, published formula, and actual calculation logic. Please report a discrepancy through the Contact page.
