Card Bounty Privacy Policy
Last Updated: May 13, 2026
Card Bounty (卡牌懸賞) is an unofficial fan-made companion app for the One Piece Card Game (OPCG), letting users browse the card catalog, manage personal collections, track wishlists, and record purchase prices. The app is not affiliated with, endorsed by, or sponsored by Bandai or the official One Piece Card Game.
This privacy policy explains how Card Bounty handles your data.
Summary
- No account, no sign-in. Everything lives on your device.
- No personal information (name, email, phone, address, location) is collected.
- No advertising, no tracking across other apps or websites.
- Camera is used only for on-device OCR to read a card number — images never leave your device.
- Anonymous analytics (via Firebase) help diagnose crashes and improve the app.
Data Stored on Your Device
The following data is created and kept only on your device (and Apple’s iCloud backup if you have it enabled at the OS level — Card Bounty itself does not sync to iCloud):
- Your card collection records (card number, purchase date, price, currency, grading info, photos, notes, favorite flags)
- Wishlist entries and folders
- App preferences (display currency, appearance theme, captain name, profile avatar)
- Cached card catalog images for offline browsing
Card Bounty does not transmit any of this data to our servers or to third parties.
Camera Access
Card Bounty requests camera access to scan OPCG cards. The scanner runs Apple’s on-device Vision OCR to extract the card number text. Camera frames are processed in memory and immediately discarded — no image is uploaded, saved to your photo library, or sent anywhere.
Photo Library Access
The app uses Apple’s PhotosPicker (out-of-process picker) when you choose a profile avatar. We do not request library access permission, and we only receive the single image you explicitly pick. The selected image is resized and stored locally on your device.
Analytics and Crash Reporting
Card Bounty uses Firebase Analytics and Firebase Crashlytics (from Google) to collect anonymous usage and stability data:
- Product interaction — Which app features are used (anonymous events such as card scans, copies added, wish toggles, in-app purchases)
- Crash data — Stack traces and device state when the app crashes
- Performance data — Launch time, network response time
All data is anonymous. We do not collect personally identifiable information. This data is not linked to your identity and not used for cross-app tracking. You can review the App Store Privacy Label for the full disclosure.
Debug builds run by the developer do not send analytics data.
In-App Purchases (Tip Jar)
Card Bounty offers optional one-time tips through Apple’s In-App Purchase. Tips are processed by Apple StoreKit and the App Store. Card Bounty never sees, stores, or transmits your payment card details — Apple handles the entire payment flow. Tipping is voluntary and does not unlock any features (the app is fully free).
Network Activity
Card Bounty connects to Google Cloud Storage (read-only) to download:
- The OPCG card catalog (card metadata JSON)
- Card images for display
These requests are anonymous, contain no personal data, and are subject to Google’s privacy policy.

Children’s Privacy
Card Bounty does not knowingly collect personal information from children under the age of 13. There is no account creation, social feature, or user-generated content shared between users.
Your Choices
- You can clear cached card images at any time in Settings → Data → Clear cache.
- You can delete the app to remove all locally stored data, including the captain name and avatar.
- You can disable Apple’s “Allow Apps to Request to Track” in iOS Settings — Card Bounty does not track you regardless.
