1 Introduction
This Privacy Policy describes how PT Devora Digital Kreasi ("we", "us", or "our") handles information in connection with your use of the mobile application KanjiDraw : Japanese Kanji ("the Application").
We respect your privacy and are committed to protecting it through transparent practices. This policy explains what information is processed when you use our educational software.
2 Information We Do Not Collect
The Application is engineered to function entirely without collecting personal information. Specifically:
- No Account Required: You do not need to register, create a profile, or log in with an email address, phone number, or social media account.
- No Personal Identifiable Information (PII): We do not collect names, addresses, phone numbers, or government identifiers.
- No Location Data: The Application never requests, accesses, or tracks your GPS or device location.
- No Financial Data: We do not collect credit card, bank account, or billing details.
3 Data Stored Locally on Your Device
To deliver personalized learning and progress tracking, the Application stores data locally on your device storage (using local preferences and SQLite database):
- Learning Progress & SRS Statistics: Studied kanji records, repetition intervals, quiz scores, accuracy ratings, and streak counters.
- User Preferences: Audio volume, auto-play TTS toggles, and stroke guide display preferences.
- Stroke & Canvas Input: Your handwriting strokes on the canvas are processed entirely in-memory on your device for stroke recognition and geometric accuracy analysis. No canvas drawings or stroke vector paths are ever uploaded or transmitted over the internet.
This data remains exclusively on your device and can be cleared at any time through the Application's settings or your device application storage manager.
4 Device Features & Permissions
The Application uses standard, non-intrusive operating system capabilities:
- Text-to-Speech (TTS): Audio pronunciation for kanji readings (Onyomi, Kunyomi) and example sentences is synthesized on your device using native platform speech engines (such as Google Speech Services or Apple Speech Synthesis). We do not record your microphone, voice, or surrounding audio.
- Storage Access: Limited to storing local learning progress and caching app resources on your local device sandbox.
5 Third-Party Advertising & Services (Google AdMob)
To keep this educational application free and accessible, we display advertisements provided by Google AdMob (Google Mobile Ads SDK). The Application utilizes:
- Banner Ads: Neatly integrated display banners within designated screen sections.
- Interstitial Ads: Full-screen advertisements displayed only at natural study transition points (such as completing a quiz or drawing session), strictly governed by display cooldowns.
- Rewarded Video Ads: User-initiated video advertisements that are entirely optional and require explicit user opt-in (e.g., unlocking a quiz hint or bonus challenge time).
Google AdMob may process certain technical data to serve ads, control frequency capping, combat fraud, and provide aggregated analytics:
- Device Identifiers: Mobile advertising identifiers (such as Android Advertising ID / AAID).
- Technical Information: IP address (for general country/region location detection), device manufacturer, model, and operating system version.
- Ad Interaction Telemetry: Diagnostic logs and performance metrics related to ad views and clicks.
Google's use of information collected through AdMob is governed by the Google Privacy Policy & Terms. You may manage or opt out of personalized advertising at any time through your device settings (e.g., Settings > Google > Ads on Android).
6 Children's Privacy (COPPA / GDPR-K Compliance)
KanjiDraw : Japanese Kanji is an educational tool designed for students of all ages, including children learning the Japanese language. Because the Application does not collect, store, or transmit any personal identifiable information, it complies with the Children’s Online Privacy Protection Act (COPPA) and General Data Protection Regulation (GDPR) standards for minors.
If a parent or guardian believes that any personal information has inadvertently been provided to us, please contact us immediately so we can take appropriate measures.
7 Security of Your Data
Because your learning data is contained solely within your device's isolated application sandbox, the security of your data is governed by your device's security controls (such as screen locks and OS encryption). We encourage users to maintain up-to-date operating system security patches.
8 Changes to This Privacy Policy
We may update our Privacy Policy periodically to reflect enhancements in the Application or regulatory changes. Any updates will be published on this page with an updated "Last Updated" date. Continued use of the Application after revisions constitutes your acceptance of the updated terms.
