Privacy Policy

JLPT Book does not collect, store, or transmit any personal data to external servers. All study data — including flashcard progress, SRS schedules, quiz results, XP, streaks, and achievements — is stored locally on your device. User preferences and progress can optionally sync via iCloud when enabled on your device; this data does not pass through the developer's servers. No third-party analytics, accounts, or remote services are used.
