About Mutal Unnie — our team, calendar checks and editorial standards
25 October 2026 · Team, calculations and editorial policy
Mutal Unnie brings Korean birth-chart traditions into everyday planning. We explain what calendar checks establish, where forecasts have limits, and how we review missed predictions.

What does Mutal Unnie help you do?
Mutal Unnie is a Korean saju app for preparing for important days. Saju is a traditional reading of birth-date and time pillars. Flow cards, event registration, D-day countdowns and the day's one-line flow are free. Schedule Full Care costs 35 Bok and includes a briefing the day before and guidance on the day. Check each screen for the scope and price of features opened with Bok.
Who makes the app, and how can you contact us?
GATEPOP Inc. creates and operates Mutal Unnie. The support and privacy contact is gatepopkorea@gmail.com, the same address published on our Support and Privacy Policy pages.
What do our calculation checks cover?
Checking a calendar calculation does not validate a prediction about your future. The table describes checks recorded in the web engine comments and repository README, including the comparison made on 3 October 2026. These records do not establish accuracy for every era, place or interpretation.
| Check | Scope recorded in the repository |
|---|---|
| Solar terms | Compared with KASI's 2027 and 2028 data: matching dates and minute displays differing by 0–1 minute. |
| Lunisolar conversion | No mismatch in 55,002 solar→lunar→solar round trips covering 1900–2050. |
| Web time correction | Optional correction reflects Korea's historical standard-time and daylight-saving changes. |
| App versus web | The app uses entered KST clock time without automatic historical-time or daylight-saving correction. The web calendar offers optional correction. |
What are our editorial standards?
We avoid fear-based claims and promises of outcomes. We do not guarantee admissions, relationships or earnings. Our Hit Ledger guide explains publishing missed forecasts as well as hits and comparing them with actual records. Readings are not a basis for medical, legal or investment decisions. Keep calculated dates, traditional interpretation and observed results distinct.
How can you report an error?
Please send the page URL, the disputed passage and the reference you checked. For a date issue, include the input date, clock time, time zone and selected correction options. Use the support form or email above. Avoid sending personal information that is unnecessary to investigate the issue.
