Privacy Policy

1. About this app

This policy applies to Schulte Grid - Brain Training, provided by Everyday Game Studio, with application identifier com.xuzengfei.schulte.y2026. The app offers local attention, memory and reaction training, challenges, local two-player activities and training history. It has no accounts, cloud score synchronization, purchases, chat or standalone analytics SDK.

2. Local information

Training results, difficulty and challenge progress, unfinished puzzle drafts, language and sound settings, completed-round counts and the most recent ad-display timestamp are stored locally on your device. App code does not upload training records to a developer server. The app does not request contacts, photos, camera, microphone or precise location.

3. Advertising and service data

The app integrates Google AdMob (Google Mobile Ads SDK) and User Messaging Platform (UMP). It requests non-personalized interstitial ads at occasional breaks after training. The SDK may process IP address and approximate location derived from it, device and app information, ad views and interactions, crash logs, performance information, consent choices and technical identifiers permitted by the configuration below. Google and its advertising service providers process these data to deliver and measure ads, operate services and prevent fraud. Non-personalized advertising does not mean that no data is processed. Training remains usable when an ad is unavailable.

4. Device advertising identifiers

The app does not request App Tracking Transparency (ATT) authorization or access the IDFA. Advertising is enabled only on iOS 14.5 or later; older supported systems can run training without ads. Publisher first-party ID is disabled. Apple or Google may process other app-scoped identifiers, diagnostic information and privacy-preserving attribution data under their policies.

5. Privacy choices

The app updates UMP consent information at launch and presents a required consent form when it can do so without interrupting training. Where required, Settings → Privacy choices opens Google’s privacy options so you can review or change your choice. Settings also links to this policy.

6. Retention, deletion and requests

Local app records remain until removed using operating-system app-data controls or uninstalling the app, subject to device backup and restore settings. We do not operate a server account for your training data. Google determines retention for data it controls according to its policies. Depending on your location, you may have rights to access, correct, delete, restrict or object to processing, withdraw consent or complain to a supervisory authority. Contact us about developer-controlled data; requests about Google-controlled data may also need to be sent to Google. Google services may process data outside your country under their applicable safeguards.

7. Children, security and changes

The app does not ask users to submit personal information to the developer to train. If a parent or guardian believes a child has provided personal information, please contact us. We will review the concern and take appropriate action. Network services and device storage cannot be guaranteed completely secure. If data practices change, we will update this policy and its date.
