# Luma Quest Privacy Policy
Last Updated: August 28, 2026
This policy applies to the current version of Luma Quest. This application is an offline casual puzzle game.
## I. Locally Stored Information
The application stores your nickname, avatar selection, level, experience points, level completion status, collections, mission progress, and settings for sound effects and haptic feedback on your device.
If you create a local account, the application saves your username and stores password verification data derived using a random salt and the PBKDF2-HMAC-SHA256 algorithm. This verification data is stored in the iOS Keychain; your password is not stored in plain text.
## II. Guest Mode and Accounts
You may use Guest Mode without creating an account. If you create a local account, your current guest progress will be transferred to the new account. Local accounts are available only on the current device and do not support cloud synchronization, third-party logins, or password recovery via email.
## III. Network, Permissions, and Third-Party Services
The current version does not upload your personal information to a server, nor does it integrate advertising, analytics, or tracking services. It does not request access to your contacts, photo library, camera, microphone, or location. Core functionality does not require an internet connection.
## IV. Managing Your Data
In the User Center, you can modify your nickname and avatar, adjust sound and haptic settings, reset game progress for the current profile, or delete the current account and its local data. Deleting an account also removes the corresponding Keychain verification data; other local accounts remain unaffected.
Account deletion cannot be undone within the application; please proceed only after confirming your decision.
## V. Data Retention and System Backups
Relevant data remains on your device until you delete it via the application or uninstall the application itself. Depending on your system settings, iOS may include application files in device backups. Keychain data may persist after uninstallation; therefore, to fully delete an account, please perform the account deletion within the application before uninstalling it.
## VI. Game Rewards
Experience points, collections, and badges are in-game achievements; they cannot be purchased, exchanged for cash, or redeemed for monetary rewards. ## VII. Policy Updates and Contact Information
Luma Quest
This policy will be updated accordingly if the data processing methods change in future versions. For assistance, please use the app developer support contact details.
Release Note: Prior to official distribution, developers must configure valid and accurate support contact information in the app store and ensure that the privacy declarations submitted to the store align with the actual version of the app.
