chicchi.work and related services respect user privacy and explain what information is handled and why. This policy applies to the personal website, related indie services, and Trip Supporter.

2. Information We Handle

The personal website may handle access logs, technical information about browsers and devices, and information sent through inquiries.

Trip Supporter may handle sign-in information, profile information, group, trip, itinerary, chat, day note, and settlement-related content, location information during trips, uploaded images, notification tokens, device information, diagnostics, analytics events, advertising-related information, and purchase status information.

3. Purposes of Use

Information is used to provide the services, authenticate users, share trip information, send notifications, enable location sharing, verify purchase status, prevent abuse, investigate issues, improve quality, respond to inquiries, and comply with legal obligations.
