1. Your game stays on your device
Teumsae Block stores your game progress, scores, level and experience, challenge history, language and sound settings on your device. There is no game account or DesignFab game server. We do not receive your saved game records. Clearing the app's data or uninstalling it removes the locally stored records and settings.
2. Advertising and consent
The Android app uses Google AdMob and Google's User Messaging Platform. To provide and measure ads, analyse service performance and prevent fraud, the Google Mobile Ads SDK may collect and share your IP address (which can indicate approximate location), device or account identifiers including advertising identifiers, app and ad interactions, and diagnostic information. SDK data is encrypted in transit.
Where required, the app displays Google's consent message. You can revisit available ad privacy choices from the app's settings. You may also reset or delete your advertising ID in Android settings. Ads are requested only when the consent system permits them. A rewarded ad is shown only when you choose it.
Google's use, retention and deletion of this information are described in the Google Privacy Policy. We do not control all retention periods used by Google or its advertising partners.
3. Automatic language selection
In automatic language mode, the app contacts GeoJS over HTTPS. This discloses your connection's IP address to GeoJS so it can return a country code. The app uses that code to choose Korean, Japanese or English. It does not request GPS location, send game records or use the response to identify you. Selecting a language manually disables subsequent automatic country lookups.
GeoJS uses Cloudflare's network. Its handling of service and error logs is explained in the GeoJS Privacy Policy. This support page does not perform an IP-country lookup.
4. Sharing a score
If you choose to share, the app creates a card containing your score and level and passes it, together with share text, to the app you select. DesignFab does not post automatically or choose recipients. The selected app's policy governs any shared copy. Temporary cards are stored in the app cache; cards more than 24 hours old are cleaned up when another card is created. Copies saved outside the game must be managed in the receiving app.
5. Support requests
If you email us, we receive your email address and the information you include. We use these to respond and resolve your request, and keep correspondence only as needed for that purpose or applicable obligations. Contact us to request access, correction or deletion of support information. We cannot retrieve game records that remain only on your device.
6. Services and international processing
Google, GeoJS and the hosting provider for this page may process information in countries other than your own under their respective policies. The website host processes ordinary connection information needed to deliver and secure this page. We do not add analytics, advertising scripts or account sign-in to this support page.
7. Intended audience
This release is intended for adults aged 18 and over and is not directed to children. If you believe a child has sent personal information directly to DesignFab, contact us so we can review and delete it where appropriate.
8. Your choices and updates
You can change language and ad privacy settings, stop using the app, delete local app data, and contact the relevant service provider about information it holds. We will update this page when the app's data practices change and revise the effective date above. For questions or requests, contact info@designs-fab.com.
