Sokoban Puzzle: One Box Push Privacy Policy

Effective date: 2026-09-04

Brainer ("we", "our", or "us") provides the Sokoban Puzzle: One Box Push (소코반 퍼즐: 한칸창고) Android application. This policy explains what information the app handles, why it is handled, and the choices available to players.

Information stored on the device

The app stores game progress, unlocked stages, best move and push counts, unfinished board positions, bounded recent undo history, and whether a hint or undo was used in an unfinished attempt. It also stores delivery badges, Daily Challenge and Daily Contract records, completion streaks, the newest seven local days of Daily Contract awards, selected cosmetic safety-helmet and cargo-livery IDs, sound and haptic choices, and limited eligibility flags for advertising and the official in-app review request. Undo history is limited to the most recent 256 moves for each unfinished campaign stage and Daily Challenge.

The app does not request or store a birth date or age range. An earlier build could store a broad local age choice; version 0.1.1 clears that legacy value and no longer displays an age-selection screen.

This information stays in the app's private storage and is not sent to a Brainer server. The app also creates short procedural sound files in its private cache; these files contain no user information and can be regenerated.

Android may include the game-progress preference file in encrypted cloud backup or device-to-device transfer when the user has enabled those platform features. Advertising and consent SDK preferences are excluded from the app's explicit backup rules. Players can delete gameplay progress and cosmetic unlocks from Settings. Clearing app data or uninstalling deletes local data, although a later Android restore can restore a previously backed-up game-progress copy.

Sharing delivery records

When a player taps Share in Delivery Records, the app prepares a plain-text summary of aggregate local achievements and opens Android's system share chooser. Nothing is sent unless the player selects a receiving app or service. The summary does not include an account or device identifier, saved board position, undo history, or advertising and consent state. The selected recipient handles the shared text under its own privacy policy. Brainer does not separately receive or store a copy.

Advertising and consent

Google Mobile Ads is bundled in the app and supplies an Android startup component. The app uses Google Mobile Ads SDK 25.4.0 for optional rewarded hints and limited interstitial advertising. Ads are available to all players, but every ad request is configured for Google's teen age-restricted treatment with a maximum T content rating. This disables personalized advertising and remarketing and prevents transmission of the Android advertising identifier. The app tags User Messaging Platform requests as under the age of consent, so it does not ask players for advertising consent.

According to Google's SDK disclosure, Mobile Ads can automatically collect and share an IP address, which may be used to estimate approximate location; app and ad interactions such as launches, taps, and video views; diagnostics such as launch time, hang rate, and energy use; and device or account identifiers such as an app set ID. Google describes the purposes as advertising, analytics, and fraud prevention and states that this data is encrypted in transit using TLS. The app's age-restricted configuration limits personalization and identifier use as described above.

Children and teens

The app does not ask for a name, email address, birth date, age range, or other direct personal identifier. All players can receive age-restricted rewarded or interstitial ads. The app does not personalize ads or transmit the Android advertising identifier. Brainer does not knowingly operate a server that collects personal information from children through this app. A parent or guardian with a privacy question can contact us using the details below.

In-app reviews

After a meaningful gameplay milestone, the app can launch Google Play's official in-app review flow. A rating and optional review text are entered in Google Play's interface, encrypted, and handled by Google Play. A submitted review may be public on Google Play or private to the developer during a closed test. The app cannot read the entered rating or review, whether the review card appeared, or whether a review was submitted. Players can manage or delete their reviews through Google Play or their Google Account.

Analytics, accounts, purchases, and notifications

The app does not include a separate analytics or crash-reporting SDK, does not create user accounts, does not offer purchases, and does not send push notifications in the current release.

Security, retention, and deletion

Local progress remains until the player resets it, clears app data, or uninstalls the app, subject to the Android backup and device-transfer behavior described above. Information processed by Google is retained under Google's applicable policies. We use current supported SDKs and limit app permissions to network access needed for consent and advertising.

Because the app does not create an account or send gameplay data to a Brainer server, there is no Brainer account or remote gameplay record to delete. Players can erase the app's local gameplay data from Settings and can clear all app data through Android system settings.

Changes to this policy

We may update this policy when the app's behavior, third-party services, or legal requirements change. The effective date will be updated when material changes are published.
