1. Scope

This policy applies to the MINE LOGIC Android app provided under the ERSIYAN brand by 애플파이, a Korean sole proprietorship represented by 탁진.

The app does not provide registration, user accounts, payments, advertising, or online leaderboards.

2. Information processed on the device

Language, theme, visual appearance, and sound settings, together with the history of problems already offered in Enhanced Training, may be processed or stored in the app-specific storage area on the user’s device.

This information is used on the device to retain the selected display and sound preferences and to manage problem selection in Enhanced Training.

3. Nickname and result cards

An optional nickname entered by the user is processed in the app for display on a result card. The result card image is generated on the user’s device.

When the user directly chooses to save or share, Android system features may send a copy of the result card to a location or app selected by the user. The copy may contain the nickname entered by the user, game results, and, when selected, a completion date.

4. Server transmission and automatic sharing

MINE LOGIC is not designed to automatically collect or transmit app settings, Enhanced Training problem-offer history, nicknames, or game results to a server operated by the developer. The developer does not sell information processed in the app.

A result card is sent to a destination selected by the user only when the user chooses a save or share action. The app does not automatically share it with an external party.

5. Permissions and external code

The app package does not request the Android INTERNET permission or sensitive access permissions for information such as location, contacts, camera, microphone, photos, or files.

The current app does not include features or libraries for advertising, user behavior analytics, or telemetry.

6. Deletion

App settings and Enhanced Training problem-offer history can be deleted by clearing MINE LOGIC app data in Android settings or by uninstalling the app.

A share-ready result card PNG may be created temporarily in the app-private cache/shared_cards directory. Older files or files above the cache limit may be removed when another card is prepared for sharing. These cached files can also be deleted by clearing the app cache or app data, or by uninstalling the app.

A result card copy saved to photos or files, or shared with another app or service, may remain outside MINE LOGIC and may not be removed when app data is cleared or the app is uninstalled. The user must delete that copy separately from the location or service where it was saved or sent.

7. Children’s privacy

MINE LOGIC is not designed to intentionally collect children’s personal information on a server operated by the developer. A parent or guardian can guide a child not to use identifying information, such as a full name or contact details, as a nickname when sharing a result card.

8. Accessing this policy

This policy is provided at ersiyan.com. Existing app versions may first open applepie.im in an external browser and then move to the same policy path at ersiyan.com. This is website use separate from the app’s gameplay functions, and Cloudflare may process the IP address and request information for that visit.

See the ERSIYAN Website Privacy Policy for details about website access.

9. Contact and changes

Questions about information processing in MINE LOGIC can be sent to asoul122@naver.com.

If app functions or information-processing practices change, this page will be updated with the changes and their effective date. This policy was first effective on July 29, 2026. It was last updated, and this version became effective, on August 25, 2026.
