This privacy policy applies to the following iOS applications developed by cliechen ("we," "our," or "us"):

• ☕ CremaShuffle (com.cliechen.CremaShuffle)
• 📖 HanVault (com.cliechen.HanVault)
• 🎲 DiceTrove (com.cliechen.DiceTrove)

Data Collection

None of our apps collect, store, or transmit any personal data. These apps are designed to operate entirely on your device with no network access.

• No analytics or tracking SDKs are used
• No personal information is requested or collected
• No data is sent to external servers
• No third-party services are integrated

Local Data Storage

The following app data is stored locally on your device only, using iOS UserDefaults or the app's document directory:

• CremaShuffle: Best score, unlocked achievements, effect settings, music/SFX preferences, and tutorial status (stored locally in UserDefaults)
• HanVault: Learning progress, SRS review records, bookmarked words, daily mission state, and study statistics (stored locally in UserDefaults)
• DiceTrove: Roll history (stored locally)
• Coin Flip: Flip history and statistics (stored locally)
• Private Vault: Encrypted photos and passcode (stored locally, never transmitted)
• Animal Pop: Game progress and level data (stored locally)
• DayVault: Calendar events, journal entries, custom event types, and period cycle data (stored locally in document directory)

All locally stored data can be cleared by deleting the app from your device.

Encryption

Private Vault uses AES-GCM encryption via Apple's CryptoKit to encrypt all photos stored in the vault. The encryption key is derived from your passcode and never leaves your device. No one — including us — can access your encrypted photos without your passcode.

Security

Since these apps have no network capabilities, there is no risk of data transmission. Private Vault additionally protects access with Face ID / Touch ID and a passcode lock screen. DayVault also uses Face ID to lock the app and protect your private journal entries.

Children's Privacy

Our apps do not collect any data from anyone, including children under 13. All content is suitable for general audiences.

Third-Party Services

Our apps do not integrate any third-party services, SDKs, or APIs. No data is shared with any third party.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated effective date.
