Katsumi Sakurai ("we") provides the iOS app "Tower Battle" ("the app"). This policy explains how information is handled in the app.
The app does not send any personal information to our servers — we do not operate any servers for this app. Settings, stage progress and scores are stored only on your device (iOS UserDefaults) and are removed when you delete the app.
The app uses Google AdMob to display ads. AdMob may collect information such as device identifiers (including advertising identifiers), ad interaction data, device type and OS version, approximate location derived from IP address, and diagnostic information, in order to deliver and measure ads and to prevent fraud.
Where consent is required (EEA, UK, Switzerland and other regulated regions), the app shows a consent form provided by Google's User Messaging Platform on first launch. You can change your choice at any time from Settings → "広告のプライバシー設定" (Ad privacy options) in the app.
The app does not use the advertising identifier (IDFA) to track you across apps and websites owned by other companies.
The app does not knowingly collect personal information from children under 13.
We do not sell or share your personal information with third parties. Data handled for advertising is governed by the Google policies linked above.
We may update this policy. Changes will be posted on this page with a new "last updated" date.
