Privacy Policy

Kuku Drill

Last updated: October 6, 2026

Holy App ("we") provides the iOS app Kuku Drill (the "App"). This policy explains how information is handled in the App.

1. Information we do not collect

The App does not collect information that directly identifies you, such as your name, address, phone number, or email address. There is no account registration or sign-in.

2. Data in the App

Multiplication answers and correct-answer streaks are processed on your device. Play records, including completion times and progress, are stored on your device. We do not send your answers or play records to our servers.

3. Advertising

The App displays advertising through Google AdMob, provided by Google LLC. AdMob and its advertising partners may collect IP addresses (including estimated coarse location), advertising and other device identifiers, device information, advertising and product interaction data, and crash and performance diagnostic information to deliver ads, measure impressions, and prevent fraud.

Where consent is required, including the European Economic Area, the United Kingdom, and Switzerland, the App presents a consent screen through Google User Messaging Platform (UMP) or a similar tool and serves ads according to your choice. The App explains Apple’s App Tracking Transparency (ATT) request before asking for permission and follows your choice when using advertising identifiers and related tracking. You can use the App even if you deny permission.

4. Crash diagnostics

The App uses Firebase Crashlytics, provided by Google LLC, to identify crashes and technical problems. Crashlytics collects crash details, device model, OS version, installation identifiers, and related diagnostic information. Dependent Firebase libraries also handle diagnostic information to maintain SDK quality. We do not attach names, custom user IDs, multiplication answers, or play records to diagnostic reports. The App does not use Firebase Analytics.

5. Third-party services

The app recommendations in Settings are downloaded from a shared catalog hosted by Cloudflare. Connection information, such as your IP address, is transmitted to the provider to deliver the content. Your multiplication answers and play records are not sent to the catalog. Selecting a recommended app opens Apple’s App Store interface. Each provider handles information under its own privacy policy.

6. Retention and deletion

Play records remain on your device until you delete them. You can erase play records from record management in Settings. Deleting the App removes data stored on your device. The retention and deletion of information collected by advertising and diagnostic services are governed by the policies of those service providers.

7. Changes to this policy

We may revise this policy as laws change or as the App gains new features. When we do, we will publish the updated text and revision date on this page.
