Privacy Policy

Effective date: 23 October 2026

JLPT Flashcard Quest is an iPhone app published by Usukhbayar Batbayar. This policy explains what the app does with information on your device.

Data Not Collected

JLPT Flashcard Quest does not collect data. Progress is stored on your device only. There is no analytics, no ads, and no tracking. Nothing you study is sent to me or to anyone else.

Learned words, review dates, mock test scores, streaks, XP, and settings stay on the device. If you delete the app, that progress is removed from the device. I cannot restore it, because it never leaves the phone.

Purchases

JLPT Pro purchases are processed by Apple under Apple's privacy policy. I do not receive your payment details.

Notifications

Optional reminders use local notifications scheduled on the device. They are not sent through a server. You can turn them off in iOS Settings.

Children

The app does not collect personal information from anyone, including children.

Changes

If this policy changes, I will post the updated text on this page with a new effective date.
