# Privacy Policy — Kanji Striker
Last updated: June 3, 2026
This Privacy Policy describes how Kanji Striker by Shima Bird ("the App")
handles information when you use it.
## 1. Information We Collect
We do NOT collect, store, or transmit any personally identifiable
information about you. The App does not require an account, sign-up,
or login.
## 2. Data Stored On Your Device
The following information is stored locally on your device only, and is
never sent to us or any third party:
- Game settings (audio volume, language preference, accessibility toggles)
- Your vocabulary learning progress (which words you have answered correctly)
- Your in-app purchase entitlements (which content packs you own)
- High scores and round statistics
This data lives in the App's sandboxed storage area and is removed if
you uninstall the App.
## 3. In-App Purchases
In-app purchases are processed entirely by the Apple App Store (on iOS)
or the Google Play Store (on Android). We do not see or store your name,
email address, billing address, or payment details.
For information about how Apple and Google handle your purchase data,
please review:
- Apple Privacy Policy: https://www.apple.com/legal/privacy/
- Google Privacy Policy: https://policies.google.com/privacy
## 4. Third-Party Services
The App does NOT integrate any analytics SDKs, advertising networks,
or behavioral tracking services. We do not use any third-party
trackers to monitor your activity.
The only external service the App uses is the platform-native
in-app purchase API (StoreKit on iOS, Google Play Billing on Android),
which is required to process purchases.
## 5. Cross-Promotion
The App contains a promotional banner linking to "Shima Bird — Japanese
Learning", another app developed by the same studio. Tapping the banner
opens your device's App Store / Play Store and does not transmit any
data from this App.
## 6. Children's Privacy
The App is intended for users 13 years of age and older. We do not
knowingly collect any information from children under 13. If you
believe a child under 13 has provided information through the App,
please contact us and we will take steps to address it.
## 7. Data Security
Because we do not collect or transmit personal data, there is no
data on our servers that could be subject to a breach. Data stored
locally on your device is protected by your device's operating system
security model.
## 8. Changes to This Policy
We may update this Privacy Policy from time to time. Material changes
will be reflected by an updated "Last updated" date at the top of this
page. Continued use of the App after a change indicates acceptance of
the updated policy.
