K-Map Linker is built by a small team. If you've found a bug, have a feature request, or just want to share how the app is working for your trip, we'd genuinely love to hear from you.
Frequently Asked Questions
Does the app work without internet?
Core lookups for popular places work offline thanks to a built-in database, but live address search, AI translation, and the latest map information require an internet connection.
Why does the app ask for microphone permission?
Microphone access is only used when you tap the voice input button — to convert your speech into a search query or translation request. No audio is recorded or stored. See our Privacy Policy for full details.
Why does the app ask for location?
Location is used to detect when you've arrived at Incheon Airport so the app can automatically show the right limousine bus and train options. The location is read once, used locally, and never sent anywhere.
What languages does the app support?
English, Chinese (中文), Japanese (日本語), Korean (한국어), Spanish (Español), and Arabic (العربية). You can change languages anytime from the top menu inside the app.
How do I delete my data?
Since K-Map Linker doesn't store any data on a server, there's nothing to delete remotely. Uninstalling the app — or clearing app storage in your device settings — removes all locally stored preferences and favorites instantly.
I'm a tour operator / partner — how do I get in touch?
Send a note to joonykim69@gmail.com with "Partnership" in the subject line.
