We are based in Japan.

We ensure and maintain a data protection framework that complies with the standards required under the Act on the Protection of Personal Information of Japan. This is achieved by entering into appropriate data protection agreements (such as Data Processing Addendums or Standard Contractual Clauses (SCCs)) with our external service providers (Shopify, Google, etc.) or by verifying the robust safety management measures they implement.
(2) Application to Non-Residents of Japan (GDPR, PIPL, etc.)
If you access our services from outside Japan, your personal data will be transferred to and stored in countries outside your country of residence (including Japan, the United States, Canada, or other third countries). In accordance with applicable laws and regulations in the countries or regions where data is transferred (such as the GDPR and the Personal Information Protection Law of China (PIPL)), we implement appropriate security measures, such as entering into SCCs, to protect your information. By using our services from outside Japan and providing your personal information, you acknowledge that your information may be transferred to these countries.
