About Unolocus
Last Updated: 2026-10-23
Vision
"Everything you need to know about Korea, in one place." Unolocus aims to be a data hub where residents, foreign nationals, and visitors can quickly find practical information about living in or visiting Korea. Starting with Korea, the long-term vision is to expand into Japan, Vietnam, the United States, and other countries.
Mission
We keep complex tax calculations, visa requirements, government benefits, and tourist information accurate and up to date so users can make informed decisions on their own. All calculators run entirely in your browser — inputs are never sent to our servers, so you can use them safely without privacy concerns.
Operator
Unolocus is an independent side project run by a single software engineer based in Korea, working in the AI and web development field. It was started in May 2026 to address the information-access difficulties the operator personally observed while helping foreign friends and family settle in Korea. For operational inquiries: contact@unolocus.com.
What we offer now
We provide 20 Korean tax, social insurance, labor, real estate, housing-lottery, and policy-fund calculators; 10 guides on government benefits and foreigner life topics; 5 tools for visiting and living in Korea as a foreigner (visa & K-ETA, airport transit, SIM/eSIM, attractions, mart closures); and holiday calendar and CSAT schedule pages. We operate in Korean (ko-KR) and English (en-KR).
Content sourcing and verification policy
We only state figures confirmed against official government and public-agency sources. Values we could not confirm are left out, and we link to the official site instead so you can check them yourself. Major sources include the National Tax Service, the Ministry of Justice, the Ministry of Land, Infrastructure and Transport, the Ministry of Employment and Labor, the Financial Services Commission, and the Korea Tourism Organization; source links appear at the bottom of each page. When a tax law or policy changes, we update the page and its verification date. English content is AI-translated and then human-reviewed.
Data confidence labels
At the top of each tool or guide page, we show the last verification date and the verification method (Auto-verified via Korea Legislation API, Quarterly manual review, or Updated on regulation change). The status switches to 'Re-verification soon' after 4 months and 'Over a year — pending update' after 12 months. If you see either status, check the official source links on the page for the latest information. Estimates are marked 'estimated' or 'approx.'. All tax, legal, and financial results are for reference only — consult a qualified professional before any actual filing or application.
Revenue model
Unolocus is free to use. Operating costs are covered by Google AdSense ads and a small amount of affiliate links (Klook, etc.). Ads and affiliate links are kept separate from editorial content, and recommended tools or guides are selected based on official sources and user utility — independent of affiliate revenue.
Roadmap
In 2026 we plan to deepen Korean content (more guides, 30+ attractions, expanded visa information). From 2027 onward we plan to expand into Japan (jp), Vietnam (vn), and the United States (us) as resident information hubs. Suggestions for improvement, error reports, and feature requests are always welcome.
