Privacy policy

Effective: October 29, 2026 · Developer: Hyunjin Lee (JAY Project)

Chagok is a zen 3-tile matching puzzle played without an account. This policy explains what information is stored on your device and what Google advertising services process.

1. Information Stored on Your Device

Your stage progress, highest cleared level, daily challenge history and scores, attendance streak, unlocked teaware collections, and audio/haptics settings are stored locally on your device (via SharedPreferences). They are used solely to preserve your gameplay and limit ad frequency. None of this data is transmitted to our servers.

2. OS Backups and Data Deletion

Depending on your device settings, app data may be included in OS backups (iCloud / Google Drive). Deleting the app or clearing its data in device settings will permanently remove all local progress.

3. Information Processed by Google Mobile Ads

We use the Google Mobile Ads SDK for banner, interstitial, and rewarded ads, and Google UMP for consent management. Google may process approximate location (based on IP), device identifiers, ad interaction data, and diagnostic metrics to deliver, personalize, and measure ads. On iOS, we do not request App Tracking Transparency (ATT), so IDFA is not used for cross-app tracking.

4. User Consent and Choices

In jurisdictions where required (such as the EEA/UK), a consent dialog is presented on first launch. You can review and update your consent choices anytime in Settings > Privacy Settings. Gameplay remains completely free and accessible regardless of your consent choices.

5. Children’s Privacy

Chagok is not directed to children under 13, and we do not knowingly collect personal information from children.

6. Retention and Third-Party Policies

Locally stored data remains on your device until you uninstall the app. Information processed by Google is governed by Google’s Privacy Policy.

7. Contact and Updates

If you have any questions regarding privacy, please contact us via email. Any changes to this policy will be posted on this page with an updated effective date.
