Handling of Personal Information

Effective date: 2026-10-04 (last revised: 2026-10-06)

Fuji Bit Inc. ("we") handles the personal information (including personally referable information) collected through the mobile app Wagering Wanderer (iOS / Android, the "App") as described below, in accordance with Japan's Act on the Protection of Personal Information (APPI) and other applicable laws. This page supplements our Privacy Policy and summarizes, in one place, what we collect, how and why, who receives it, how long it is kept, and your rights.

1. Business Operator

• Operator: Fuji Bit Inc.
• Contact for personal information: support@fujibit.com (English and Japanese)
• Address and name of representative: provided without delay upon request.

2. Information We Collect and How

The table below lists the information the App handles, when it is collected, why, where it is stored or sent, and how long it is kept.

The App does not ask for your real name, postal address, phone number, or device location (GPS, etc.). When you link with Apple ID, Apple's screen may ask whether to share your name, but the App neither stores nor transmits it. Because player names are public on the leaderboard, please do not use your real name or anything that identifies you.

3. Purposes of Use

We use personal information only for the following purposes:

1. Providing the App's game features (records, badges, tickets, etc.)
2. Compiling and displaying the global leaderboard
3. Carrying records over through account linking, and identity verification
4. Delivering and measuring ads (personalized ads only with your consent)
5. Granting in-app purchases and restoring them
6. Responding to inquiries and requests
7. Preventing abuse, handling failures, and improving the service

We will obtain your consent in advance before using personal information beyond these purposes.

4. Third-Party Provision and External Transmission

Except as required by law, we do not provide personal information to third parties without your consent. The App uses the following services for the purposes above, and information is sent to these providers:

• Google Firebase (Firebase Authentication / Cloud Firestore, provided by Google LLC, USA): storage of leaderboard and account-linking data. Firestore data is stored in the Tokyo region (asia-northeast1), but authentication data may be processed on servers outside Japan, including in the United States. We entrust this processing to Google. Privacy and Security in Firebase
• Sign in with Apple (Apple Inc., USA) / Google Sign-In (Google LLC, USA): account linking, if you choose it
• Pangle (an advertising platform operated by the Bytedance group; a provider outside Japan) and advertising partners that bid for the ad: ad delivery. The Pangle SDK does not start until you answer (on iOS, tap "Continue" on) the ad question. Pangle End User Data Privacy Policy
• App Store (Apple Inc.) / Google Play (Google LLC): in-app purchase payments

By the nature of the leaderboard, your player name, score, best stage and total runs are shown to other users who open the in-app leaderboard.

5. Provision to Third Parties in Foreign Countries

As described in section 4, using the App may involve providing or transmitting personal information (including personally referable information) to providers outside Japan. As required by the APPI, we provide the following information:

• Country of the recipient: United States (Google LLC, Apple Inc.). For Pangle and its advertising partners, their location and data storage locations are set out in Pangle's privacy policy.
• That country's personal information protection system: The United States has no comprehensive federal law equivalent to the APPI; personal information is protected by state laws such as the California Consumer Privacy Act (CCPA) and by sector-specific laws. For details on each country's system, see the Personal Information Protection Commission of Japan's survey of foreign personal information protection systems (Japanese).
• Measures taken by the recipient: Google applies security measures such as encryption and access control under the Firebase Data Processing and Security Terms. Apple, Google and Pangle handle information under their respective privacy policies. We use each provider after reviewing its terms of service and privacy policy.

Leaderboard participation (transmission to Firebase) starts only after you agree in the consent dialog shown on the leaderboard screen.

6. Security Measures

To prevent leakage, loss or damage of personal information, we take the following measures:

• Technical: All communication is encrypted with HTTPS (TLS). Cloud Firestore security rules allow reads only by authenticated users, restrict writes to the document matching your own UID, validate name length and score ranges, and forbid deletion from the client.
• Organizational and personnel: Access to personal information and to the Firebase console is limited to authorized staff, and viewing or use beyond the stated purposes is prohibited.
• Data minimization: Only the minimum information needed for the leaderboard is sent; we do not collect payment details, real names or addresses. Firebase does not start until you agree to join the leaderboard, and the ad SDK does not start until you respond to the ad screen on first launch.
• Understanding the external environment: For information processed on servers outside Japan, we handle it with an understanding of the recipient country's system, as described in section 5.

7. Your Rights (Access, Correction, Deletion, Suspension of Use)

You may request notification of the purposes of use, disclosure (including records of provision to third parties), correction, addition or deletion, suspension of use or erasure, and suspension of third-party provision of personal information we hold about you. Many of these can be done yourself inside the App.

7-1. In the App

• Correct your player name: change it from the player name in Settings. The new name is also applied to the leaderboards for the current periods (all-time, today, this week, this month).
• Stop sending to the leaderboard: turn off "Join leaderboard" in Settings; no further scores are sent (to erase data already sent, see 7-3).
• Unlink an account: "Unlink Apple" / "Unlink Google" in Settings removes the Apple / Google association while keeping your records.
• Sign out: "Sign out" in Settings leaves the linked account and switches this device to a new anonymous ID.
• Ad settings: change your consent to personalized ads anytime from "Ad settings" in Settings. On iOS use Settings > Privacy & Security > Tracking; on Android reset or delete the advertising ID under "Ads" in the device settings.
• Delete on-device data: "Reset Best Record" / "Reset Badges" in Settings, or uninstall the App.

7-2. By email

Send requests for disclosure, correction, suspension of use and the like to support@fujibit.com. Because leaderboard data is managed under an anonymous ID, we will ask for details such as your player name, the approximate time you last played, and (if linked) the email address of the linked account, in order to locate your records and verify your identity. Once your identity is verified, we will respond without delay.

7-3. Deletion

To delete your leaderboard records and Firebase account, use "Delete account / data" in Settings or follow the Account / Data Deletion Request page. We delete the data and confirm completion within 30 days.

For access or deletion of information collected by Pangle, contact Pangle through the channels described in its privacy policy.

8. Minors

If you are a minor, please obtain your parent's or guardian's consent before joining the leaderboard, linking an account, or making in-app purchases. Do not include your real name, school name or other identifying information in your player name. Parents or guardians who want a child's information deleted can contact us as described in section 7.
