For how personal information is handled on our website and across our corporate activities in general, please see our Personal Information Protection Policy. If you move from the App to an external website or service, the handling of information there is governed by that operator's own rules, and this policy does not apply.
The information the App collects falls into three groups: information collected by the third-party services the App uses (Section 5), information stored in Google Firebase if you join the world ranking, and information stored only on your device. We do not operate any servers of our own.
When you register a player name to join the world ranking in the App, the following information is stored in Google Firebase (Cloud Firestore) and shown to other users. If you do not register a player name, none of this information is sent to the world ranking.
Please do not use information that could identify you, such as your real name or phone number, as your player name.
The following information is stored only on your device and is never sent to us or to any third party.
On Android, the App requests only two permissions: INTERNET, for network communication, and ACCESS_NETWORK_STATE, to check connectivity. On iOS, the App shows the App Tracking Transparency (ATT) prompt before it uses the advertising identifier.
The App also has no dedicated service for collecting crash information.
If you email us, we collect your email address and the contents of your message so that we can reply.
We use the information we collect for the purposes below.
We do not handle your information beyond the scope of the purposes above without obtaining your prior consent. We do not use the information we collect to identify any specific individual.
The App uses the third-party services below. These services handle information in accordance with the privacy policies of their respective providers.
The App uses Google AdMob, an advertising service from Google LLC, to show banner ads and interstitial ads (full-screen ads shown between screens). AdMob may automatically collect information, including advertising identifiers, in order to deliver ads and measure their effectiveness. The content rating of the ads shown in the App is capped at General audiences (G).
In order to understand how the App is used and to improve it, we use Google Analytics for Firebase (Firebase Analytics), provided by Google LLC. We collect event data — screen views, when a game starts and ends, and when you use the share feature — along with the device information attached to those events. We do not set any user ID or user property that would identify you as an individual.
We use Cloud Firestore, provided by Google LLC, to store world ranking records, and Firebase Authentication (anonymous sign-in) to issue the anonymous ID used to manage each record. Firebase Authentication may collect information such as IP addresses to prevent abuse.
The App is distributed through Google Play (Google LLC). The App Store (Apple Inc.) version is scheduled for release in October 2026. Information relating to app downloads is handled in accordance with the policies of each platform operator.
The App includes a feature for sharing your score with other apps. You choose which app to share with, and we never receive what you share.
In the European Economic Area, the United Kingdom, and other regions where consent is required, the App shows a consent form at start-up using Google's User Messaging Platform. We start serving ads and collecting analytics only after you have responded to the consent form and ad requests have been determined to be permitted. Until you answer, analytics collection stays turned off.
You can bring up your consent settings again and change them at any time from the "Privacy" button on the title screen (where your region is covered by the consent form).
The App asks for your consent to this policy when you first launch it. You can withdraw your consent at any time from "Privacy" > "Withdraw consent" on the title screen. If you do, we stop serving ads and collecting analytics, and your world ranking record is deleted (Section 9).
You can reset or limit the use of your advertising identifier at any time from your device settings. Examples are given below; the wording may differ depending on the version of your operating system.
Even if you opt out, you will still see ads, but they will no longer be tailored to your interests.
We do not provide the information we collect to third parties, except in any of the following cases.
When we outsource work, we exercise the necessary and appropriate supervision over the contractor.
The third-party services described in Section 5 collect information on their own responsibility, and that collection does not necessarily constitute provision of personal data by us.
The player name, score, and other details you register in the world ranking are shown to other users of the App as a result of your own registration.
We take the protection of children's privacy seriously. The App is not a service directed exclusively at children under 13, and we do not knowingly collect personally identifiable information from children under 13. Respecting the intent of COPPA (the Children's Online Privacy Protection Act of the United States) and other relevant laws, we will promptly delete any such information if we learn that information from a child under 13 has been collected.
The ads shown in the App are capped at the General audiences (G) content rating. The age rating we declare for the App in the app stores is likewise All ages.
If you are a parent or guardian and become aware that information about your child has been collected, please contact us at the address in Section 12. We will check the matter and respond promptly.
Retention periods are as follows.
You can delete your own record (player name, score, play time, etc.) from our servers at any time via "Privacy" > "Remove me from the world ranking" on the title screen of the App. If you are offline, the deletion is sent the next time you are online. Your record is also deleted if you choose "Withdraw consent."
World ranking records are automatically deleted 90 days after you last used the App. Records that can no longer be deleted from the App because you uninstalled and reinstalled it or changed devices are also deleted after 90 days. If you would like a record deleted sooner, please contact us at the address below with the subject "World ranking record deletion request," and include your player name and the approximate date you registered.
Once we have verified your identity, we will act on your request within a reasonable period, except for information we are required by law to retain.
We take the necessary and appropriate measures to keep the information we collect secure and to prevent it from being leaked, lost, or damaged.
We may change this policy in response to amendments to the law, changes to the features of the App, or changes to the third-party services we use. The revised content takes effect from the time it is posted on this page. If we make a significant change, we will give notice within the App or on our website.
For questions or requests regarding this policy or the handling of information in the App, please contact us by email at the address below.
