comfortech (hereinafter referred to as “the Operator”, “we”, “us”, or “our”) establishes this Privacy Policy (hereinafter referred to as “this Policy”) regarding the handling of user information, including personal information, in the smartphone application “Solitaire” (hereinafter referred to as “the App”).

1. Information Collected and Collection Methods

The App collects the following information:

  1. Information Provided Directly by the User
    • Inquiry Information: Text submitted via the in-app inquiry form and optional reply email address.
  2. Automatically Collected Information
    • Firebase Analytics Usage Data: Events such as screen_view, game_started, game_abandoned, stage_cleared, daily_challenge_cleared, standard_game_cleared, hint_used, hint_unavailable, undo_used, victory_cta_tapped, onboarding_completed, settings_changed, paywall_viewed, paywall_checkout_tapped, and purchase_completed, together with related information such as screen name, game mode, move count, duration, star count, hint usage, setting changes, and purchase funnel interactions.
    • Information Automatically Collected by Firebase Analytics: App instance ID, device, operating system, and app information; approximate region inferred from the IP address; and automatic events such as first_open and session_start. This information may be collected in association with identifiers such as the app instance ID.
    • Purchase Information: Information regarding the purchase and restoration of premium features (e.g., optimal hints, stage packs, and premium pass). Payment transactions are processed directly by Apple Inc. or Google LLC, and the Operator does not directly collect credit card information.

The App saves game progress, completion status, and visual appearance settings exclusively on the device and does not sync or transmit this data to the Operator’s servers. The inquiry information, purchase information, and Firebase Analytics usage data described above are transmitted externally to the listed service providers. Firebase Analytics does not receive the specific layout of the game board or the user’s detailed sequence of moves.

2. Purpose of Use

Collected information is used for the following purposes:

  1. To maintain and improve basic functions of the App (Klondike solitaire gameplay, stage and daily challenge progress, optimal hints, etc.).
  2. To improve stage difficulty balance and content supply quality.
  3. To understand usage of screens, settings, onboarding, and purchase flows and improve the user experience.
  4. To respond to user inquiries and support requests.
  5. To provide premium features (optimal hints, stage packs, and premium pass), and to verify and manage purchase status.

3. Data Storage and Management

  1. Local Device Storage: Ongoing games, stage completion records, cumulative scores, and appearance settings are saved strictly on the user’s device. They are not transmitted to or stored on the Operator’s servers, and the App does not create user accounts.
  2. Transmission to Firebase Analytics: Events concerning gameplay, screen views, setting changes, onboarding, purchase flows, and completed purchases may be transmitted to Firebase Analytics, a service provided by Google LLC. Essential game functions remain fully usable even in offline environments without network connectivity.

4. External Data Transmission and Third-Party Provision

To manage premium feature purchases/restorations, process inquiry submissions, and analyze app usage, the App utilizes third-party service providers. Corresponding information may be transmitted to the following providers:

The App does not display third-party advertisements or use advertising tracking SDKs. Firebase Analytics is configured not to collect advertising IDFA, Android Advertising ID (AD_ID), or IDFV. However, identifiers such as the Firebase app instance ID and other automatically collected information needed for Analytics may still be collected for the purposes described above.

5. Photo Data

The App does not request photo library access permissions, nor does it collect, store, or transmit photo data.

6. Disclaimer

While the App strives for accuracy in game progress and score recording, the Operator assumes no liability, to the extent permitted by law, for loss or inconsistency of progress data caused by device environments or app defects.

7. Data Deletion

Users can delete all local data saved on the device, including active games and appearance settings, at any time via “Settings” > “Reset Saved Data” in the App. Deleted data cannot be recovered.

8. Children’s Privacy

The App is not directed to children under 13 years of age. If we learn that a child under 13 has provided personal information, we will promptly delete such information.

9. Changes to Privacy Policy

The Operator may modify this Policy from time to time in response to legal changes or service updates. In the event of material changes, notification will be provided within the App or on related websites. Continued use of the App after changes take effect constitutes acceptance of the revised Policy.
