Information stored on your device
Block Wave saves your puzzle progress, active round, scores, stages, stars, daily challenge progress, preferences, session timing, advertising frequency records, reward claims and review-request status in app-private storage. These records support gameplay, resuming a round, remembering settings, limiting interruptions and preventing duplicate rewards. Game code does not upload these saved records. Android cloud backup and device transfer are disabled for app records.
You can play without creating an account. Brainer operates no game backend and includes no independent analytics or crash-reporting service. Google advertising services perform their own measurement and analytics as described below.
Advertising and Google services
Block Wave uses the Google Mobile Ads SDK for advertising. When advertising services run, the SDK automatically collects and shares information including your device's IP address, which may indicate approximate location; app and advertising interactions, such as launches, taps and video views; diagnostic information about app and SDK performance; and device or other identifiers, such as the Android advertising ID and app set ID. Where applicable, Google may also process identifiers related to signed-in accounts on the device. The game does not request precise location permission.
Google and advertising partners use this information for ad delivery, advertising measurement and analytics, fraud prevention, security and compliance. Ads may be personalized where permitted by applicable settings and choices. Brainer does not attach your saved game records or support emails to advertising requests. See Google's Mobile Ads data disclosure.
Ads can preload after the applicable privacy checks, before an ad appears or you choose to watch a rewarded ad. Choosing not to watch a rewarded ad does not stop all advertising data processing. Rewarded viewing is optional, and a continuation reward is granted only after the SDK reports completion. Ordinary gameplay remains available if an ad is unavailable.
Privacy choices
Google's User Messaging Platform manages applicable advertising privacy choices. It stores and processes consent selections, and consent signals may be sent with advertising requests. Where applicable, use the ad privacy choices in the game's Settings to review or change your selections. Available choices depend on your region and Google's requirements.
Android settings provide controls to reset or delete your advertising ID. These controls do not necessarily stop processing that uses other identifiers or delete information already held by service providers. Google explains its advertising and privacy controls.
Google Play reviews
The game may invite you to leave a review through Google Play after a gameplay milestone. Reviews are voluntary and do not earn gameplay rewards. The review flow does not return your rating or review text to the game. Google Play handles submitted reviews under its policies; public reviews may be visible to Brainer and other users. You can edit or delete your review in Google Play.
Support messages
If you email us, we receive the sender address, message and any attachments you choose to send. We use them to respond, resolve your request and maintain necessary support, security or legal records. We retain them only as long as needed for those purposes and do not use them for advertising targeting. Contact auction@mekorean.com with questions or requests about this correspondence, including deletion requests; legitimate record-retention requirements may limit deletion.
Security, retention and deletion
Android app isolation helps protect local game records. Google states that Mobile Ads SDK user data is encrypted in transit using TLS and that Play review data is encrypted. These statements describe those services; no method of storage or transmission is completely secure.
Local records remain until you clear the app's storage or uninstall it, which removes your saved progress and settings. Clearing app storage or uninstalling does not delete data already collected by Google or other service providers. There is no Block Wave server account to delete.
Google and its service providers apply their own retention practices and privacy controls. Use the relevant provider's controls or contact that provider about its data. Brainer cannot promise deletion of all information held by Google or advertising partners. Learn more in the Google Privacy Policy and how Google uses information from partner sites and apps.
Audience and external services
Block Wave is intended for general users aged 16 and above and is not directed to children under 16. The game does not request birth dates or create age profiles.
Opening this policy on Blogger, our website or an advertising destination involves the browser and the relevant website or service. Those providers may process visit information or cookies under their own policies. Email providers also process messages under their own policies.
Policy changes and contact
We may update this policy when the app or its data practices change. The effective date above identifies this version. For privacy questions, contact Brainer at auction@mekorean.com or visit mekorean.com.
