2-2) Local Settings and Stored Values (Stored Internally on the Device)

To provide this feature and maintain usability, some settings/data are stored only locally in the form of
SharedPreferences, the app documents folder, or a local DB (SQLite/sqflite).

These values are not automatically transmitted to the developer’s server and may be deleted together when app data is cleared or the app is uninstalled (or depending on device policy).

(1) Country/Game Selection and Basic App Settings (SharedPreferences)

Category	Key (Example)	Purpose	Storage Location	Deletion Timing
Initial setup completion status	setup_done	Determines whether the initial setup has been completed or skipped	SharedPreferences	When app data is cleared or the app is uninstalled
Country selection history	selected_countries	Stores the history of recently selected countries	Same as above	Same as above
Currently active country	active_country	Configures the game list based on the current country	Same as above	Same as above
Currently active game	active_lotto_id	Specifies the default game to display/use for statistics	Same as above	Same as above
Selected game list	selected_lotto_ids	Stores the list of games to use for statistics/search	Same as above	Same as above
App language setting	app_locale_tag	Applies a fixed app language instead of the system language	Same as above	Same as above
Ophiuchus mode	enable_ophiuchus_mode	Reflects extended mode in zodiac calculation/display	Same as above	Same as above
JSON editor sheet usage status	json_editor_sheet_enabled	Stores whether the JSON editor bottom sheet is shown	Same as above	Same as above

(2) Selected seed time value (SharedPreferences)

Category	Key (Example)	Purpose	Storage Location	Deletion Timing
Seed reference time (date/time)	birth_datetime_iso	Stores the seed reference time used for number generation/reports	SharedPreferences	When app data is cleared or the app is uninstalled

• If the user does not separately choose a seed time, the app may generate and store the current time value to provide the feature.
• The stored value is a date/time (ISO string) and does not include direct identifiers such as an account, email address, or phone number.

(3) JSON Guide and Auxiliary UI Settings (SharedPreferences)

Category	Key (Example)	Purpose	Storage Location	Deletion Timing
JSON guide one-time display flag	json_guide_shown_{gameId}	Prevents duplicate display of the JSON editing guide	SharedPreferences	When app data is cleared or the app is uninstalled
Slot record bottom sheet usage status	slot_machine_bottom_sheet_enabled	Stores whether the slot record bottom sheet is shown	Same as above	Same as above

(4) Slot Machine Record/Probability Settings (SharedPreferences)

Category	Key (Example)	Purpose	Storage Location	Deletion Timing
Current slot record existence status	slot_machine_current_has_record	Stores whether the current record exists	SharedPreferences	When app data is cleared or the app is uninstalled
Current slot result type	slot_machine_current_outcome	Stores success/failure/pending status	Same as above	Same as above
Current slot image number	slot_machine_current_image_no	Stores the currently displayed image state	Same as above	Same as above
Current accumulated failure count	slot_machine_current_failure_count	Stores the current consecutive failure count	Same as above	Same as above
Current success probability value	slot_machine_current_success_rate_percent	Stores the success probability linked to the current record	Same as above	Same as above
Last consumed record existence status	slot_machine_last_has_record	Stores whether the last usage record exists	Same as above	Same as above
Last consumed result type	slot_machine_last_outcome	Stores the success/failure status of the last record	Same as above	Same as above
Last consumed image number	slot_machine_last_image_no	Stores the image state of the last record	Same as above	Same as above
Last consumed failure count	slot_machine_last_failure_count	Stores the accumulated failure count of the last record	Same as above	Same as above
Last consumed success probability	slot_machine_last_success_rate_percent	Stores the success probability of the last record	Same as above	Same as above
Configured default success probability	slot_machine_configured_success_rate_percent	Stores the slot success probability adjusted by the user	Same as above	Same as above

• The values above are local setting values used to maintain the slot UI state and display records.
• They are stored only inside the device and are not transmitted to a server.

(5) Temporary Storage for Number-Based Generation and AI Model (SharedPreferences)

Category	Key (Example)	Purpose	Storage Location	Deletion Timing
Number-based checkpoint (v1)	nb_checkpoint_v1_{gameId}	Maintains legacy temporary saved records	SharedPreferences	When app data is cleared or the app is uninstalled
Number-based checkpoint (v2)	nb_checkpoints_v2_{gameId}	Stores a list of checkpoints for pause/resume	Same as above	Same as above
AI model setting by game	ai_model_{gameId}	Stores AI selection weights/slot settings by game	Same as above	Same as above

• Checkpoints may include the number of attempts, recent numbers, seed-based values, saved time (UTC ISO string), and similar data.
• These are internal state values for resuming the feature and do not include direct identifiers.

(6) Local JSON File Storage (App Documents Folder)

• Path (example): app documents folder /game_json/{gameId}.json
• Content: game data (JSON) directly edited/managed by the user
• Purpose of use: local storage of game-specific data and support for statistics/search features
• Deletion: generally deleted together when app data is cleared or the app is uninstalled, but this may vary depending on OS/backup policy.

(7) Local DB (Logs/Records) Storage (SQLite/sqflite)

Depending on the feature, the app may store the following lottery record/log data in a local DB.

• UI display values such as round information/date, selected number list, generation logs, and whether fingerprint use was enabled
• Purpose of use: record lookup, statistics calculation, and management of logs saved by the user
• Storage location: local DB inside the device
• Deletion: deleted together when app data is cleared or the app is uninstalled.

(8) Temporary Files/Cache

During normal operation, the following temporary data may be generated.

• Temporary data generated during JSON parsing
• Cache for UI rendering and library operation

Temporary files may be located in cache/temporary folder areas managed by the OS,
may be automatically cleaned up according to OS policy, and are not uploaded to the developer’s server.
