Your primary data is stored in Tokyo, Japan (Supabase database). Certain processing activities involve transfers to the United States, specifically:

For EU/EEA users: Japan has been granted an adequacy decision by the European Commission (January 2019, renewed), meaning transfers from the EU to Japan are considered to provide an adequate level of data protection. For transfers from Japan to the United States, each US-based service provider operates under a Data Processing Agreement (DPA) that includes Standard Contractual Clauses (SCCs) or equivalent safeguards.

Under Japan's APPI: Cross-border transfers to the US are covered by our contractual arrangements with each processor, ensuring equivalent protection as required under Article 28 of the Act on the Protection of Personal Information.

  • AI itinerary generation: Travel preferences are sent to US-based AI providers for processing and immediately discarded after generation.
  • Email delivery: Name and email address are transmitted to send transactional notifications.
  • Analytics: Anonymized browsing data is processed in the US under Google consent mode v2.
  • Payment processing: Payment data is handled in the US under PCI DSS compliance.
