Shiro Neko ("the App") is a mobile application developed by Garcia&Friends ("we", "us", "our"). The App is a collection journal (御城印帳) for Japanese castles. This privacy policy explains how we collect, use, and protect your information when you use our App.
1. Information We Collect
Location Data: When you use the "Check-in" (登城) feature or the "Nearby Castles" feature, the App requests access to your device's location to confirm you are near a castle and to find castles around you. Your location is processed locally on your device. We do not store, transmit, or share your location data with any server.
Photos & Camera: The App lets you attach your own photos to the castles you've visited and add a personal note (your visit journal). These photos are copied into the App's private storage on your device and are never uploaded to our servers or shared with anyone. The camera and photo-library permissions are used only when you choose to add a photo.
Visits, Favorites & Preferences: Your check-ins, favorites, collection progress, language choice, and other preferences are stored locally on your device. We do not collect or transmit this data.
2. Information We Do NOT Collect
- We do not collect your name, email, phone number, or any personal identification.
- We do not require account creation or login.
- We do not collect or store your location, photos, or notes on our servers.
- We do not show ads and we do not use advertising trackers.
- We do not sell any user data to third parties.
3. Third-Party Services
The App uses the following third-party services, each with their own privacy policies:
- Google Maps SDK — Map display. The map view loads map tiles from Google. Privacy Policy
- Cloudflare R2 — Image hosting. Castle photos shown in the App are delivered from a content-delivery network; loading an image sends a standard web request (including your IP address) to fetch it. Privacy Policy
- Expo / EAS — App build and update infrastructure. Privacy Policy
- Google Play / Apple App Store — In-app purchase processing (see section 6).
4. Data Storage & Security
All user data (check-ins, favorites, journal photos and notes, preferences) is stored locally on your device. We do not operate servers that store personal user data. The castle database is bundled within the App, so the core experience works offline; an internet connection is only used to load map tiles and castle photos.
5. Children's Privacy
The App is not directed at children under 13. We do not knowingly collect any personal information from children. If you are a parent or guardian and believe your child has provided us with personal information, please contact us.
6. In-App Purchases
The App offers an optional one-time purchase (the "城主 Pass" premium unlock) that enables additional features. Purchases are processed by the Google Play Store or the Apple App Store. We do not collect or store any payment information.
7. Data Retention
Since we do not collect personal data on our servers, there is no personal data to retain or delete. Local data on your device — including your journal photos and notes — can be cleared by deleting it within the App or by uninstalling the App.
8. Your Rights
You can:
- Deny location permission — the App works without it (the "Check-in" and "Nearby Castles" features will be unavailable).
- Deny camera and photo permissions — the App works without them (you simply won't be able to attach photos to your visits).
- Delete your journal photos and notes at any time within the App.
- Delete all local data by uninstalling the App.
9. Changes to This Policy
We may update this privacy policy from time to time. Changes will be reflected on this page with an updated "Last updated" date. Continued use of the App after changes constitutes acceptance of the updated policy.
