Who makes it
The operator is OneTherapy Co., Ltd. CEO Lee Yun-seop, business registration 177-87-04156, 4F Da-5, 62 Geumjeong-ro, Paju, Gyeonggi-do, Korea. Contact: cs@sajuping.ai. The about page is the company site. This page is the product promise.
Sajuping is a consumer app on the iOS App Store and Google Play. sajuping.ai is the official landing, plus explainers, terms, and the blog. It is not a chain of fortune-teller shops. It is myeongni calculation and conversation, shipped as software.
What it does — and what it does not
What it does: cast a chart from birth data, then answer daily fortune, compatibility, and the next question. It is built to remember, so you do not re-explain your palja every time. What it does not: appoint a spouse, an exam result, or a death date. It does not scare you into buying a talisman. It does not sort people into a “bad saju.”
The tradition itself is explained at /what-is-saju. This page is how Sajuping treats that tradition as a product. That is why the two pages are not the same essay.
Why we are not publishing a 35% anxiety drop
An early marketing draft claimed “a 35% average drop in anxiety among paid subscribers.” We required a re-measurement before publishing. That verification is not done. So the number is not on this site. An unsourced healing claim would weaken trust, not build it.
What we do publish are public store reviews that talk about anxiety and comfort, on /en/reviews. A review is not a statistic. It is a cited experience. The more you want a number, the more those two must stay apart.
