Privacy Policy
This policy explains how “Spot the Difference - dumapp” (the “App”) and this website handle information.
1. Overview
The App requires no account. The App itself does not send game progress or settings to servers operated by dumapp, and dumapp does not collect information directly from the App that identifies a user.
2. On-device data and backup
The App stores game progress, clear records, unlock status, Hanamaru balance and history, language/notification/sound/haptic settings, trophies, and an on-device value used to detect restoration to another device. That value is not transmitted.
Game data and ordinary settings can be erased through “Settings → Reset all data.” Deleting the App removes on-device data. On Android, depending on device and Google Account settings, Android Auto Backup may store App data in a private area of Google Drive and restore it after reinstallation or a device change. Android backup settings control this feature.
3. Advertising
The App uses Google AdMob. To deliver and measure ads, AdMob may process an advertising identifier, IP address, device information, and ad impression or interaction information. Depending on region, device settings, advertising choices, inventory, and the Ad-Free Premium entitlement, the App may show personalized, non-personalized, or limited ads, or no ad.
Where consent management is required, the App shows Google’s consent message. Where available, choices can be reviewed or changed through “Settings → Ad privacy settings.” Device advertising or tracking settings may provide additional controls.

4. In-app purchases
Google Play or the Apple App Store processes Ad-Free Premium payments. The App may receive a product ID, purchase state, and transaction identifiers needed to provide or restore the purchase and revoke the entitlement after a refund. These are not sent to or stored on a server operated by dumapp, and dumapp does not receive payment-card details. See Purchase support.
5. Image delivery and this website
App images and this website use Cloudflare’s delivery infrastructure. Cloudflare may process or log IP address, access time, and request information for delivery, security, and abuse prevention. This website stores the selected display language in browser local storage.
6. Notifications and analytics
The App uses local notifications scheduled on the device only; dumapp sends no push notifications from a server. The App includes no behavioral analytics SDK added by dumapp. Advertising, store, and delivery providers process information under their own policies.
7. Children’s privacy
The App is not designed or marketed to children under 13. It does not ask for a date of birth, exact age, or age band, and dumapp does not knowingly collect personal information directly from children under 13. A parent or guardian who believes a child may have provided information to dumapp can contact us below.
8. Third-party services and international processing
The App uses Google AdMob, Google Play, the Apple App Store, Android Auto Backup / Google Drive, and Cloudflare. These services may operate outside Japan and process information internationally.
