The rules your product lives under
Personal Information Protection Act (PIPA)
Supervised by the Personal Information Protection Commission, with strict rules on consent and on transferring personal data abroad.

Your destination markets
Going to Europe or the US adds GDPR and the US state privacy laws. It is cheaper to design for them in the same pass than to retrofit them.

Questions
Do you work in Korean?
I work in English. For Korean-language products I build the interface and its structure, and the copy comes from a native writer.
How do we start?
With a small, fixed-price first step. The contact page shows my current availability.
Can you help us prepare for the US or EU?
Yes: a review of the architecture and data handling, and what must change for those markets, as engineering guidance rather than legal advice.
Where else to find me
Other markets: United States, United Kingdom, European Union, United Arab Emirates, Saudi Arabia, Japan.
