Casino Rules Coach Privacy Policy

Established October 29, 2026

BUNKASAI, INC. ("we," "us," or "our") sets out this privacy policy (the "Policy") for how we handle personal information in "Casino Rules Coach" (the "App"), our app for learning casino rules.

1. Information we collect

We collect the following information:

  • What you send us in an inquiry or a request regarding your information, and your contact details (email address, phone number, and your name if you give it)
  • Details you share when contacting us, such as your device, OS, and App version

Your drill answers, titles, destination and language settings, and purchase records are stored only on your device. We do not collect them.

2. Information collected by outside companies

The App includes software from outside companies for showing ads and analyzing crashes. This software sends the information below directly from the App to each company, without passing through us. Each company handles the information under its own privacy policy. These companies include companies located in the United States.

  • Showing ads: advertising identifier (IDFA on iOS, advertising ID on Android), IP address, device and OS type, ad impressions and taps, and your ad consent status
  • Analyzing crashes: what happened when the App crashed, device and OS type, App version, and an identifier generated for each installation

About ads:

  • If you buy any item in the App, we stop showing ads, and the ad software no longer runs
  • In regions that require consent, such as the European Economic Area and the UK, we ask for your consent before ad-related data is used. You can change your choice at any time from "Ad privacy choices" in the App's Settings
  • On iOS, the system asks whether to allow tracking with the advertising identifier. All features of the App work even if you don't allow it
  • You can reset your advertising identifier or limit its use for ads in your device settings

Payments for in-app purchases are handled by the app store operators. We do not collect your credit card or other payment details.

3. How we use information

We use the information we collect to:

  • Respond to inquiries and requests, and verify your identity
  • Investigate problems with the App
  • Provide, maintain, and improve the App
  • Create statistics in a form that does not identify individuals

4. How long we keep information

  • We keep inquiries, requests, and contact details for three years after our last exchange, and then delete them
  • We use identity documents submitted with a request only to verify your identity, and delete them promptly once verification is complete
  • Information stored on your device is erased when you delete the App

5. Sharing with third parties

  • We do not share the information we collect with third parties without your prior consent, except as required by law. This does not apply to outsourcing under Section 6 or to sharing statistics that cannot identify individuals.
  • If we transfer the App's business to a third party, or the business is succeeded through a merger or otherwise, we may provide the information to the successor in accordance with the law. The successor will handle it only within the original purposes of use.

6. Outsourcing

We may outsource all or part of the handling of personal information to outside companies, to the extent needed for the purposes of use. The main work we outsource is receiving and storing inquiries by email and phone. We choose companies that can handle personal information properly, and supervise them as necessary and appropriate.

7. Outsourcing to companies in other countries

The companies in Section 6 include companies located in the United States. These companies have a system in place, through contracts and other means, to take measures consistent with the purpose of Chapter 4, Section 2 of Japan's Act on the Protection of Personal Information. For information about that country's personal information protection system, see the website of Japan's Personal Information Protection Commission (survey of personal information protection systems in other countries).

We check that these measures continue to be taken, and will provide information about them on request.

8. Security measures

We take the following measures to prevent leaks, loss, or damage of the information we collect, and otherwise keep it secure:

  • Organizational: We have assigned a person responsible for handling personal information, and limit who handles it
  • Personnel: We require everyone who handles personal information to keep it confidential
  • Physical: Devices used to handle personal information are screen-locked and protected against loss and theft
  • Technical: Administrative accounts use two-factor authentication, and access is limited
  • Understanding the foreign environment: We take these measures with an understanding of the overseas system described in Section 7

9. Requests to access, correct, or delete

  • You may ask us, in the way we specify, to disclose, correct, stop using, or delete information about you.
  • Verifying your identity: For requests to disclose information or to tell you how we use it, we ask you to submit an identity document. For requests only to delete or stop using information, we verify your identity in a simple way, such as matching the contact details you used in your inquiry
  • What we answer: Until we can verify your identity, we will not answer, including whether we hold the information you ask about
  • Fees: We charge 1,000 yen per request to disclose information or to tell you how we use it, and reply by email. There is no fee for requests to correct, stop using, or delete information
  • We do not hold information stored only on your device, so it is not subject to these requests. You can erase it by deleting the App

Send requests to the contact in Section 11.

10. Age

The App is intended for people aged 18 and over.

11. Contact

For inquiries and requests, contact [email protected].

12. Business information

  • Name: BUNKASAI, INC.
  • Address and name of representative: We will promptly provide them if you ask through the contact in Section 11

13. Changes to this Policy

We may change this Policy as needed. Changes take effect when we announce them in the App or by other appropriate means.
