Privacy Policy
Last updated: May 17, 2026 / 日本語
BPM Japan G.K. ("we", "us", or "our") provides this Privacy Policy ("Policy") regarding the handling of user information (which may include personal information) collected through our smartphone game application "Gun Bounce" (the "App").
1. Overview
The App is a single-player casual action game that does not require user registration or account creation. The App does not collect any directly identifying personal information such as your name, email address, phone number, postal address, precise location, contacts, photos, camera, or microphone input.
Gameplay data such as stage progress, in-game coins, lives, and settings are stored only on your device's local storage and are not transmitted to our servers.
2. Information We Collect
(1) Information stored locally on your device (not transmitted)
- Gameplay data such as stage progress, in-game coin balance, lives remaining, power-up drop rate, and ad display counters.
- App settings such as language, sound on/off, and vibration on/off.
This information is stored only on your device (via SharedPreferences) and is not transmitted to our servers.
(2) Analytics information (Firebase Analytics)
- The App uses Firebase Analytics, provided by Google LLC, to collect anonymized usage data for the purpose of improving service quality and game design.
- Example events collected: app launches, stage start / clear / fail, revive (continue via rewarded ad) events, ad impression / view events, and in-app action counts such as settings changes.
- Example device information collected: OS version, device model, app version, language setting, approximate region (country level), days since install, and an anonymous app instance ID assigned by us.
- We do not seek to identify individual users from this information alone.
(3) Advertising information (Google AdMob)
- The App displays advertisements (banner, interstitial, and rewarded ads) through Google AdMob, provided by Google LLC.
- AdMob and its partner ad networks (including SKAdNetwork participants) may collect advertising identifiers (IDFA / AAID), device information, approximate location (country / region level derived from IP), and ad impression / click event data for the purpose of ad delivery, optimization, measurement, and fraud prevention.
- In jurisdictions where the GDPR applies (EEA, UK, Switzerland, and similar), we present a consent form via Google's User Messaging Platform (UMP) and control whether personalized ads are served based on your consent.
- On iOS, in accordance with App Tracking Transparency (ATT), we present the system permission dialog before any tracking begins. If you do not allow tracking, the IDFA is not provided and only limited, non-personalized targeting is performed.
3. Purposes of Use
We use the collected information for the following purposes:
- To operate and provide the basic features of the App;
- To persist your gameplay progress, coins, lives, and similar data on your device;
- To improve the quality of the App, fix bugs, and develop new features;
- To analyze and balance stage difficulty and game design;
- To deliver, optimize, and measure the effectiveness of advertisements;
- To prevent fraudulent use and click fraud, and to ensure security;
- To respond to inquiries.
4. Disclosure to Third Parties
We do not disclose user information to third parties except in the following cases:
- When the user has given consent;
- When required by law;
- When necessary to protect the life, body, or property of a person and obtaining the user's consent is difficult;
- When information must be shared, to the extent necessary, with external service providers used to provide the App (see next section).
5. External Services
We use the following external services (including SDKs) to operate and improve the App. The handling of information by each service is governed by the respective provider's privacy policy.

7. Data Retention
- On-device data: Retained on your device until the App is uninstalled or its data is cleared via device settings.

- AdMob advertising data: Retained in accordance with Google's advertising data retention policy. See here for details.

8. Consent: Acquisition, Change, and Withdrawal (GDPR / ATT)
- In GDPR-applicable jurisdictions (EEA, UK, Switzerland, and similar), the Google UMP consent form is shown on first launch to obtain consent regarding analytics and personalized advertising.
- You may review, change, or withdraw your consent at any time via the "Privacy Settings" entry on the in-app Settings screen (shown only in GDPR-applicable regions).
- On iOS, the App Tracking Transparency permission dialog is presented on first launch. The permission status can be changed at any time via Settings > Privacy & Security > Tracking on your device.
- When consent is withdrawn, we discard any cached ads and subsequently serve only non-personalized advertisements.
9. Opting Out of Personalized Advertising
You may stop or limit personalized advertising through the following methods:
- iOS: Open the Settings app > Privacy & Security > Tracking and disable tracking for the App. You may also limit Apple's personalized ads under Settings > Privacy & Security > Apple Advertising.
- Android: Open the Settings app > Google > Ads and choose "Delete advertising ID" or "Opt out of Ads Personalization".
- EEA / UK: Reopen the UMP consent form from "Privacy Settings" in the App's in-game Settings screen.
- Google account-wide ad settings: Manage your preferences via My Ad Center and Google Ads Settings.
10. Data Storage and Security
- Gameplay data, settings, and in-game items are stored only on your device (via SharedPreferences) and are not transmitted to our servers.
