Tool & content standards

1. We start with a real task

Tools are selected to simplify a repeated calculation or conversion. Inputs stay focused on what the result needs, and the output includes enough context to support the user's next decision.

2. Methods and exclusions are disclosed

• Each complete guide explains inputs, processing rules, and how to read the result.
• Rates, prices, and fees that can change are entered by the user whenever practical.
• Financial, health, legal, and safety-related outputs are references, not professional decisions.
• When an external standard is relevant, the tool explains its scope and limitations.

3. Examples and boundaries are checked

We review typical examples plus empty, zero, large, date-boundary, and invalid inputs. Korean and English pages are checked for equivalent meaning, while file tools are reviewed for supported formats and saved output.

4. Important decisions require a source check

Results reflect the values and assumptions shown on the page. Contracts, payments, tax, healthcare, and equipment safety settings should always be checked against official records, product instructions, or qualified advice.

5. Ads do not control tool results

Ads and affiliate links are identified separately. They do not change calculations, recommended ranges, or guidance, and they are never required to use a tool.
