Privacy Policy

Last updated: September 2026

Juseyo ("the app") is a Korean phrase learning app. This policy explains what data the app handles. The short version: the app does not collect, transmit, or sell any personal data.

Data we collect

None. The app has no user accounts, no analytics SDK, no advertising SDK, and no servers of its own. We never see who you are or how you use the app.

Data stored on your device

To remember your progress, the app stores the following on your device only:

• Phrases you have viewed and your quiz results (used for spaced-repetition review)
• Phrases you have saved as favorites
• Whether you have completed the welcome screens
• Whether you have unlocked the full content
• Your approximate trip date (if you choose to set one), used for the countdown and daily phrases

This data never leaves your device. Deleting the app deletes it.

Purchases

The optional in-app purchase is processed entirely by Apple (App Store). We do not receive your payment details or any personal information about the purchase. The app only asks Apple whether this Apple ID has unlocked the full content.

Notifications

If you turn on the daily reminder, the app schedules local notifications on your device. No push server is involved and no notification token is collected.

Audio

All audio is bundled inside the app and plays offline. The app does not use the microphone.

Children

The app is not directed at children under 13. It includes an optional slang section with common Korean swear words, taught for recognition only. The app collects no data from anyone, including children.

Changes

If this policy changes, the updated version will be posted at this address with a new date.
