Privacy policy

Updated October 18, 2026

Operator and scope

Asomana (representative: Kota Seki) handles information for Asomana Dice Games under this policy.

Data stored on your device

Match states, tutorial progress, statistics, rules and display preferences are stored on your device for resuming play and displaying the app. Guest saves are not uploaded. In sign-in-enabled versions, account saves also synchronize to the cloud.

Advertising and consent

We use Google AdMob and User Messaging Platform. IP addresses and approximate location inferred from them, device and app information, device identifiers (such as advertising identifiers), ad impressions and interactions, diagnostic information such as crash logs and performance data, and consent choices may be processed. Diagnostic information may be used for troubleshooting, SDK improvements, advertising and analytics; other information may be used for ad delivery, measurement and consent management. Processing varies by region, device settings and consent. Validation builds may use test ads; distribution builds use production ad units. Ad availability depends on consent and serving status. Where required, use Ad privacy settings in the app to change your choices.

Support inquiries

We use the email address, message and optional device details you provide to answer support requests and investigate issues. Please do not send passwords or other secrets.

Optional sign-in

The app offers optional Apple or Google sign-in. All games remain available without an account. Firebase Authentication uses the account identifier, provider and any name or email supplied by the provider to manage and display sign-in status. The app does not receive your Apple or Google password. Apple and Google sign-in may create separate accounts. Firebase Authentication and Google Sign-In may process IP addresses, authentication information and diagnostic information for secure optional sign-in, fraud prevention and service operation. Authentication and cloud sync are optional account functions, separate from advertising consent.

External services and international processing

Advertising providers may process information outside Japan. See Google’s explanations below. We do not sell user information or disclose it without consent except where required by law or otherwise legally permitted.

Retention, deletion and your rights

Delete device data through data management in the app settings. Support information is retained as needed to handle your request and removed when no longer needed. Contact us to request access, correction, deletion or restriction; identity verification may be required.

Children, safeguards and revisions

Users who need parental consent should obtain it before using the app. We take reasonable safeguards against unauthorized access and disclosure. This page will be updated when features or data practices change, with appropriate notice of material changes.

iOS tracking permission and ads

Advertising consent and iOS App Tracking Transparency (ATT) permission are separate choices. Standard ads are requested only when ATT is authorized and required consent permits ads. When ATT is denied or restricted, limited ads (LTD) are requested only if Google UMP permits an ad request. LTD does not use IDFA and restricts personalization and features requiring local identifiers. Publisher first-party ID is disabled. No ads are loaded when ATT is not determined, unknown, checks fail, or required consent is unavailable. Limited ads may still use IP addresses for delivery, and programmatic LTD may use cookies or local storage exclusively for fraud and invalid traffic detection. This does not mean no information is processed. Permission and consent are checked when loading and immediately before display; old ads are discarded when choices change. Every game remains playable without permission. Change ATT in iPhone Settings and applicable consent under Ad privacy settings in the app.

Cloud saves and storage location

After sign-in, match states, tutorial progress, results, rules, language and display settings are stored in Cloud Firestore for use on devices signed in to the same account. We use a dedicated Dice Games Firebase project; Firestore is in the United States multi-region nam5. Guest saves are separate and are not uploaded unless you choose to import them. Changes upload automatically. Download another device’s saves through Settings > Account and cloud sync > Sync now. Simultaneous changes require your choice. Our app code does not attach authentication information or saved games to advertising requests. Cloud saves are retained while the account is in use and removed through account deletion. Consult the identity and cloud providers’ information for their diagnostic processing and retention.

Deleting your app account

In sign-in-enabled versions, choose Settings > Account and cloud sync > Delete account, then verify your identity with Apple or Google. This removes this app’s authentication account, cloud saves and local saves for that account on this device, and revokes the app’s provider connection. Separate guest saves, other accounts, and your Apple or Google account itself are not deleted. Deletion cannot be undone. If a step fails, it is not reported as complete; check your connection and retry. Deleting local data alone does not delete cloud data, which may be downloaded again. Contact support if you cannot use the app. Do not send passwords or verification codes. To prevent another device from restoring deleted data, we retain a protection record containing only the former account identifier and deletion time, without game content, name or email address.

Cookies and tracking on this guide site

This guide site uses Google Analytics 4 through Google Tag Manager only when you allow analytics. Page paths, referrers, device and browser information, usage activity and analytics cookie identifiers are sent to Google to understand card and dice guide usage and improve the guides. URL queries and fragments are excluded. We do not use Google signals, advertising personalization or User-ID. Analytics cookies expire within 180 days; GA4 user and event data retention is two months. Google measurement tags are not loaded before consent or after refusal. Your choice is stored in this subdomain’s local storage for 180 days and shared between both game guides. Change or withdraw it using “Analytics settings” at the bottom of any page. All guides remain available if you decline. On iOS pages opened from the app (platform=ios), measurement tags and the consent prompt are disabled regardless of earlier Web consent. Web analytics consent is separate from in-app advertising consent and ATT permission.

Website browsing and in-app advertising

The Web analytics statement above applies to this guide site. It is separate from the app’s advertising SDK, its data processing and consent screens. See Advertising and consent for in-app advertising. Advertising consent and the iOS App Tracking Transparency (ATT) permission are separate choices; advertising consent does not replace OS permission.

Access logs for delivery and security

The hosting provider may record IP addresses, access times, requested paths and browser information in access logs for page delivery, incident investigation and security. Hosting logs are separate from the optional Web analytics described above.
