Power lucky lotto is an app for managing lottery games and viewing records. Key features include:
The app does not require account creation and, by default, does not upload your data to the developer’s servers.
Most processing happens on your device.
However, for advertising, consent management, and legal compliance, third-party SDKs such as
Google Mobile Ads SDK (AdMob) and Google UMP (User Messaging Platform) may collect and process certain data (e.g., advertising identifiers).
The app stores certain data locally on your device to provide features and improve usability.
This data is generally not transmitted to the developer’s servers and is removed when you delete app data or uninstall the app (except for files you export elsewhere).

|---|---|---|---|---|
| Setup completed | setup_done |
Store initial setup state | SharedPreferences | Removed on app data delete/uninstall |
| Country history | selected_countries |
Keep recently selected countries | Same | Same |
| Active country | active_country |
Store the currently selected country | Same | Same |
| Selected games | selected_lotto_ids |
Store checked game IDs | Same | Same |

Note: “Seed time selection (optional)” is only collected if the user chooses to set it and may not be required for core app use.
The app may store generated/saved records in a local SQLite database.
log_...id, date_id or date_text (timestamp), choice1..choiceN (picked numbers), isFinger (fingerprint-related flag, etc.)You can view logs in the app’s table list/detail screens and delete them (table-level or row-level) if you wish.
The app may store game-specific JSON data in the app’s documents directory.
game_json/<gameId>.jsonThese files are stored on-device and are generally removed when the app is uninstalled, subject to OS/backup behavior.
The app uses Google Mobile Ads SDK (AdMob) and Google UMP to:
These SDKs may collect/process, for example:
In some regions (e.g., EEA/UK/CH), a UMP consent form may be shown and a Privacy Options entry may be provided where required.
For ads and consent management, some data may be processed by Google and its partners.
