Calm Sweep Privacy Policy — 차분한 지뢰찾기

Privacy Policy — 차분한 지뢰찾기 (Calm Sweep)

Effective date: October 16, 2026. Developer: Brainer Studio. Application ID: com.brainer.calmsweep. Privacy contact: auction@mekorean.com. Support: https://mekorean.com.

Calm Sweep is an offline Minesweeper game. We do not operate an app account system, login service, analytics backend or game server. You can play without an internet connection.

Game data on your device

The app stores the current puzzle, elapsed time, hint credits, daily challenge date, wins, best time, settings and whether a review request was already attempted in private app storage. This data supports save/restore and progress. It is not sent to our servers. Cloud backup is disabled by the app. Clear app storage or uninstall the app to remove this local data. There is no account to delete.

Advertising and your choices

The app integrates Google's Google Mobile Ads Next-Gen SDK and User Messaging Platform (UMP). Optional rewarded ads give an additional hint only when you choose to watch and the SDK confirms the reward. The app also counts completed games, including wins and losses: after each five completed games, it may show one automatic interstitial only when you explicitly start the next game. Abandoned games do not count. Interstitials are not shown directly on a win, loss or result screen, during initial onboarding, or on a transition protected for an in-app review request. Interstitial attempts are at least three minutes apart and limited to two per activity session; a new session begins only after thirty minutes of inactivity. These limits persist across app restarts. If an ad is not ready, is unavailable, or fails, the next game starts immediately and that opportunity is discarded rather than delayed into gameplay. There are no banners.

The SDK is initialized only when UMP indicates ads may be requested, so advertising processing can occur once that permission condition is met before an ad is displayed. Ads and consent require internet access; the core game does not. Locally stored advertising-cadence data includes the completed-game counter, a pending transition marker, and recent attempt/session times and counts. It is used to enforce these limits, is not sent to our own servers, and is removed when you clear app storage or uninstall.

Once advertising is enabled as described above, Google's advertising SDK automatically collects and shares IP address (which can estimate general location), product interactions such as app launches, taps and video views, diagnostic information, and device/account identifiers such as advertising ID, App Set ID and, if applicable, identifiers relating to signed-in accounts. Google uses this information for advertising, analytics and fraud prevention. This SDK analytics processing is separate from game records: we do not operate our own analytics backend or send your saved puzzle to our servers. Google may associate information with its own services according to its policies. We do not sell game-save data. Review Google's privacy policy at https://policies.google.com/privacy and advertising information at https://policies.google.com/technologies/ads. Data may be processed outside your country; Google's SDK uses TLS to encrypt transmission.

Where required, UMP presents consent choices before ads are requested. Available regional privacy choices may be reopened from Settings → Advertising privacy. You can also control your device advertising identifier through Android settings. Declining a rewarded ad does not prevent normal gameplay; an automatic interstitial can temporarily cover the app at the next-game transition described above. Google controls retention and deletion of data it receives; see its policies and controls. We cannot remove data held by Google through deleting your local game save.

Other features and permissions

The optional vibration permission supports haptic feedback. No camera, microphone, contacts, storage, location or notification permission is requested by game code. The merged app declares advertising ID and normal network, basic device-state, wake-lock and foreground-service permissions used by its libraries; the exact list is recorded in the release data inventory. Google Play's in-app review API may present the official review flow after a meaningful milestone. The app cannot read your rating or review. Opening the privacy policy or support site uses your browser.

Children and security

This app is intended for a general audience aged 13 and over; it is not designed or marketed specifically for children. We do not knowingly request personal information from children. Contact us with privacy concerns. Private local storage and HTTPS reduce risk, but no storage or transmission method guarantees perfect security.

Changes and contact

We will update this policy when app data practices change and publish the revised effective date. Send privacy questions to auction@mekorean.com.
