Privacy Policy
Service: Make 10 Rivals (the “App”)
1. Information collected and how it is collected
| Information | How it is collected | Main purposes |
|---|---|---|
| Automatically issued account ID, registration and authentication verification information, authentication status, and account deletion request information | Generated or received by the App and server on first use and during authentication or account deletion | Identifying accounts, verifying users, stopping use, and checking repeat requests |
| Display name set and icon selected by the user | When the profile is saved | Displaying profiles and showing them to opponents; controlling name duplication and changes |
| Game selections, answers, scores, opponents, results and history; ratings, rankings, statistics, and aggregated actions | Generated or received during play and matches | Running games, confirming results, matchmaking, rankings, displaying statistics, and preventing duplicate processing |
| Premium entitlement, pseudonymous ID used by the purchase service, and purchase status verification results | Obtained during purchases, restoration, and entitlement checks | Providing one-time Premium access, verifying purchase status, and updating entitlements after refunds or other changes |
| On-device history such as ad display intervals, App settings, and on-device authentication information | Stored by the App on the device | Controlling display frequency, preserving settings, and authentication after restart |
| Connection information such as IP addresses, random request-level IDs, error types, and processing times | When connecting to and processing requests on the server | Access control, troubleshooting, and operational monitoring. Server records do not include identifiers that identify players, matches, or purchases |
We do not ask users to register an email address or real name. Display names contain information entered by users and are shown to other users. Do not include your own or another person’s personal information in a display name. A name containing inappropriate words may be refused, and the operator may reset a name or suspend name changes under the Terms of Use. If you report a display name, the server stores the reporting and reported users, the reason, the name at the time of the report, and the time; these are used to review the report and take necessary action. If either the reporting or reported user deletes their account, the report record is deleted in the account deletion process. Information about a blocked user is stored only on your device and is used to hide that user’s display name and icon on your screen. See Section 3 for information handled by external services.
2. Purposes and where information appears
We use information for the purposes in the table above. Display names and icons, match results, and ranking information are also shown to opponents and other users. Premium adds access to detailed statistics, match history, rankings, and similar displays, but does not change playing ability or rating calculations. Free users see ads (Section 3).
3. Transfers to external services, processing, and third-party sharing
| Service | Purposes and scope |
|---|---|
| Cloudflare (Workers, Durable Objects, D1) | Server processing and storage for the API, authentication, matchmaking, match state, profiles, results, and related functions. Connection information is also processed |
| Apple (App Store in-app purchases) | One-time purchases and restoration on iOS. Purchase records held by Apple are handled separately from deletion of data by this service |
| RevenueCat | Verifying purchase and restoration status. The App sets a pseudonymous ID for the purchase service in the SDK, and the server verifies entitlements |
| Google (AdMob, User Messaging Platform) | Serving ads to free users and collecting advertising consent. The App requests only non-personalized ads. Under Google’s policies, Google Mobile Ads SDK may process information about devices and ads (such as IP address, device type, and ad displays and interactions) for ad delivery, measurement, security, and fraud prevention. Premium users do not see ads. The game remains playable if consent collection or ad preparation fails |
Each service provider’s privacy policy also applies.
4. Handling outside Japan
The service providers above (Cloudflare, Apple, RevenueCat, and Google) are primarily US companies. Information may be stored and processed on servers outside Japan (in the US and other countries or regions where they provide services). Each company handles information under its own privacy policy and safeguards based on the laws of each country.
5. Retention and account deletion
You can request account deletion through “Delete account / data” in the App. When the request is accepted, use of the account stops and you cannot return to the same account. The deletion process within 30 days of acceptance covers this service’s profile, authentication information, personal results and aggregates, rankings, purchase entitlements, and links to external purchase IDs. The scheduled processing date and completion status can be checked on the device used to request deletion.
Shared match records needed for the other player’s results, rating, and history remain. The deleted user’s public display changes to “Deleted player” and the default icon. Minimal records without authentication or display information remain where needed to answer repeated deletion requests and maintain references between data. Purchase records held by Apple and RevenueCat are outside the scope of deletion from this service’s server.
We cannot guarantee physical deletion of on-device data while the device is off, or strict fulfillment of deadlines during outages or large backlogs.
Even after deletion processing, information may remain in database backups kept for recovery (up to seven days) and server connection logs (kept for several days). These are automatically erased after their retention periods.
6. Your choices
In the App, you can change your display name and icon and request account deletion. You can review and change advertising consent in Privacy Settings within Settings. We accept questions about information held and requests under applicable law at make10rivals.support@gmail.com. We respond by email to the extent that we can verify the request is from you.
You cannot return to the same account after deletion. Restoring a purchase does not mean restoring game records or ratings.
7. Minors
People of all ages may use the App. Minors should obtain a parent or guardian’s consent before purchasing Premium. The App is not a service dedicated to the children’s category and does not ask users to enter their age.
8. Support, revisions, and contact
If you contact support, we process your email address, message, and any optional attachments as needed for support, security, fraud prevention, and legal obligations. The email service provider’s policy also applies. Do not send authentication information, complete purchase receipts, payment information, or unnecessary technical information.
If features, third-party services, laws, or operations change, we will revise this Policy and update the last updated date. Send questions about this Policy or App data to make10rivals.support@gmail.com.
