This Privacy Policy applies to the One Line Puzzle mobile application (hereinafter referred to as the "Application") available for Android and iOS platforms. This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our Application.
The Application does not require users to register an account or provide direct personal identifiers such as your real name, physical address, or phone number.
However, to provide core gameplay functions, process in-app purchases, serve advertisements, and send notifications, certain technical and device data may be collected automatically:
Device Identifiers: Advertising IDs (IDFA for iOS, GAID/AAID for Android), IP address;
Device Information: Device model, operating system version, system language settings, screen resolution;
App Usage Data: Completed levels, hints used, gameplay session duration, crash logs;
In-App Purchase Data: Secure purchase transaction tokens processed via standard Google Play Billing, Apple StoreKit, RuStore, or AppGallery payment systems.
The Application utilizes third-party Software Development Kits (SDKs) and services that may collect information used to identify your device. Below are the links to the Privacy Policies of the third-party service providers used by the Application:

Your progress in the game (level completion states, hint counts, sound and dark theme preferences) is stored locally on your device using encrypted multiplatform local database storage (Room / DataStore). Uninstalling the Application or clearing app data will remove this locally stored progress.
We may send you local and remote push notifications regarding daily level availability, rewards, or updates. You can turn off push notifications at any time by toggling the "Notifications" switch in the Application's settings screen or through your mobile device system settings.
