Privacy Policy

Last updated: June 5, 2026

Mojidex ("the app", "we") is an iOS app developed by Qtarou Studio. This policy explains what data the app handles and why. Mojidex runs entirely on your device. We operate no servers and do not collect, transmit, or sell your personal data.

1. Information stored on your device

• Learning progress — lessons completed, review schedule, XP, streaks, and collected Kanji Spirits. This is stored locally on your device only and is never uploaded to us.
• Anonymous install ID — a random identifier generated on your device, used only to tag support emails you choose to send so we can help you. It is not linked to your identity and is not used for tracking.
• In-app activity log — anonymized events (e.g. lessons started) are recorded locally on the device to power your learning records. They never leave your device.

2. What we do NOT do

• We do not have accounts, sign-in, or any backend server.
• We do not collect, transmit, or sell your personal data.
• The free version shows ads served by Google AdMob (rewarded and interstitial ads). Subscribers see no ads. AdMob may request App Tracking Transparency permission and use your device's advertising identifier (IDFA) to help serve ads.
• We do not collect your contacts, photos, precise location, or health data.

3. Purchases

Subscriptions are processed by Apple through the App Store using StoreKit. We never see or store your payment-card details — Apple handles all billing.

4. Data retention & deletion

Because all data is stored locally, deleting the app removes all of your data from your device. There is nothing stored on our side to delete.

5. Children

Mojidex is a general-audience educational app and is not directed at children under 13. We do not knowingly collect personal information from children under 13.

6. Third-party services

• Apple App Store / StoreKit (purchases & subscriptions)
• Google AdMob (ad serving in the free version; see Google's Privacy Policy)

7. Contact
