4. Legal basis (Japan)

We handle personal data in accordance with Japan’s privacy framework, including the Act on the Protection of Personal Information (個人情報の保護に関する法律). When we collect or use cookie/terminal identifiers that may fall under “personal-related information,” we provide transparency and handle data as described under the relevant APPI/PPC guidance.

5. Sharing and disclosure

We may share personal data with:

• Service providers/processors (e.g., hosting, analytics, customer support, hardware monitoring) that process data on our behalf under appropriate confidentiality and security arrangements.
• Parties necessary to fulfill requests (e.g., payment or fulfillment partners, where applicable).

• In connection with corporate transactions (e.g., merger or reorganization) where legally permitted and with notice as required.

We do not sell your personal data to third parties. However, we may provide required data to service providers to operate the service.

6. International transfers

If personal data is transferred outside Japan, we will take appropriate safeguards consistent with APPI requirements and applicable guidance. Where required, we will provide information about transfer safeguards in the relevant collection notices.

7. Cookies / terminal identifiers

We use cookies and similar technologies to operate the site, enable features, and understand usage of the service. Depending on the technology, the data may be personal-related information under APPI.

• We use identifiers to measure performance and improve reliability, including in connection with security hardware analytics (where applicable).

If specific cookie categories or partners apply, the relevant on-site notices in the consent or cookie settings should be followed.
