All of your answers and progress are stored locally on your device only:
The app offers an optional one-time purchase ("Pathfinder Pro," ₩12,000). Payments are handled entirely by Google Play Billing — payment details, card numbers, and billing addresses are never seen or stored by the developer.
To validate purchases and restore them across reinstalls, the app uses Adapty (adapty.io), a purchase-infrastructure service. Adapty processes pseudonymous data required for this purpose: a randomly generated app user ID, device and platform information (device model, OS version, locale), and purchase transaction data from Google Play. Adapty does not receive your name, email, or any of your in-app answers. See Adapty's privacy policy for details.
If you enable timeline reminders, notifications are scheduled locally on your device. No notification data leaves your device, and you can revoke notification permission at any time in Android settings.
Because your data lives only on your device, you are in full control: clearing the app's storage or uninstalling the app deletes it. Purchase records held by Google Play and Adapty are retained per their own policies; to exercise data rights regarding purchase records, you may also contact us and we will assist.
Depending on your jurisdiction (including under Korea's Personal Information Protection Act and the GDPR), you may have rights to access, correct, or delete personal data. Since no personal data about you is held, most requests are satisfied by the device-level deletion described above — but we will help with any request relating to purchase validation data processed via Adapty.
The app provides general information about immigration requirements and is not legal advice. Requirements change; always confirm with HiKorea (hikorea.go.kr) or the 1345 immigration call center. The app is not affiliated with the Ministry of Justice or the Government of the Republic of Korea.
If this policy changes, this page and the effective date will be updated. Material changes will be noted in the app's update notes.
