This is a reference translation. The Japanese version is authoritative; if any discrepancy exists, the Japanese version prevails.

Last updated: October 19, 2026

VAULT LLC (合同会社VAULT; "we") sets out this Privacy Policy ("this Policy") for how user information is handled in the game app "BE THE BOXER" ("the Service") that we provide.

1. Operator

• Operator: VAULT LLC (合同会社VAULT)
• Representative: Takumi Kawamori, Representative Member
• Address: Konotora Bldg. 7F, 1-1-14 Shimo-Meguro, Meguro-ku, Tokyo 153-0064, Japan

2. Camera video and photos

• The Service reads your body movement (joint positions) from the front camera video on your device and uses it to control the game. The video and the movement data are never saved or sent. We never receive them.
• A photo you choose for the feature that puts a face on TARGET is processed on your device, and only the cut-out face image is saved on your device. The original photo is not saved. Photos and face images are never sent.

3. Information we handle

The Service does not require account registration or sign-in. We never ask for your name, phone number or address, and the Service has no feature that reads your contacts or location. We handle the following information.

• Random device ID: a random identifier created on your device at first launch, and a random key used to verify the device. These are not advertising IDs or hardware identifiers. On our servers, only a hashed value of the key is stored.
• Support ID: a 12-character number created at first launch, shown at the bottom of the Settings screen.
• Device and app information: OS type (iOS / Android), app version and language setting.
• Saved data we keep: fight records (wins and losses, punch counts, estimated calories burned, etc.), totals, opponents beaten, avatar outfit and some settings. This is sent to our servers automatically in case your device breaks or you change devices.
• Transfer information: only hashed values of transfer codes and passwords are stored on our servers.
• News information: the numbers of the notices you have read.
• Usage records: the fact that the app was opened on a given day (used only to count how many people are playing).
• Inquiry information: the email address, Support ID, device, OS and app version, message and attached images you send through the contact form.

The following is stored only on your device and is never sent.

• Your weight (only if you enter it; used to estimate calories)
• The reference speed measured by the test punches
• Photo faces

Our servers do not store the IP address that a connection comes from.

4. Purposes of use

We use the information we obtain for the following purposes.

• To provide the Service (game progress, keeping saved data, transferring it to another device, and restoring it after reinstalling)
• To announce news, maintenance and updates
• To respond to inquiries and investigate problems (including checking saved data by Support ID, restoring it from a backup and issuing a transfer code)
• To aggregate usage (such as the number of devices that opened the app) and improve the quality of the Service
• To prevent fraud

5. Provision to third parties and outsourcing

To the extent necessary to provide the Service, we outsource data processing to the following providers.

• Vercel (Vercel Inc.): operating the Service's servers and the contact form
• Neon (Neon, Inc.): the servers' database
• Notion (Notion Labs, Inc.): managing inquiries
• Resend: receiving inquiries and sending confirmation emails
• Upstash (Upstash, Inc.): limiting how often the contact form can be sent (to prevent abuse)

The store rating prompt is shown by your device's operating system (Apple or Google). Information on that screen is handled under each company's policy.

Other than the above, we do not provide personal data to third parties without your prior consent, except where required by law or where necessary to protect the life, body or property of a user.

6. Provision to third parties in foreign countries

The Service's servers and database are located in the United States of America. Some of the providers above handle data outside Japan. We take appropriate measures, based on each provider's contracts and data processing terms, so that they handle data only within the scope of the outsourced purposes.

7. Retention and deletion

• We keep data for as long as necessary to achieve the purposes of use, and delete data that is no longer needed.
• Data on your device is deleted when you uninstall the app. You can remove a photo face at any time with "Restore original face" on the TARGET screen.
• On our servers, we keep your latest saved data and daily backups for 3 days.
• To request deletion of your data on our servers, note your Support ID on the Settings screen, uninstall the app, and then contact us through the contact form or at game@vault-tec.jp (if you keep using the app, the information will be sent again). After confirming your identity and the data concerned, we will in principle delete your saved data, backups, transfer information and usage records within 30 days. As a record of the deletion, we keep only a hash of the random device ID, the date and the number of items deleted.
• Deleted data cannot be restored. Inquiry records are kept for as long as needed to handle them.

8. Use by minors

Users under 18 should use the Service with the consent of a parent or guardian. Parents and guardians, please tell your children not to include unnecessary personal information in inquiries.

9. Security measures

To prevent leakage, loss or damage of the data we obtain, and for other security purposes, we take necessary and appropriate measures such as encrypting communications, hashing keys and transfer passwords, and restricting access to our admin tools.

10. Requests for disclosure, correction or suspension of use

In accordance with applicable law, you may request disclosure, correction, suspension of use or deletion of your data. Please send your request with the Support ID from the Settings screen through the contact form or to game@vault-tec.jp. Depending on the request, we will confirm your identity and the data concerned.
