Privacy policy

How Tomari handles your information.

This policy applies to the English-language Tomari pages and trip-planning features at tomari-drive.com/en. Tomari is operated by Ryutaro Mihara in Japan.

Information we may receive

  • Account information: identifiers and email information provided through Google sign-in and our authentication provider.
  • Trip-planning information: selected hotels, places, dates, times, travel modes and places you choose to save.
  • Search and route requests: place names, coordinates and travel settings needed to return place and route results.
  • Contact information: your name, email address, optional phone number and message when you contact us.
  • Service and usage information: technical details used to keep the site secure, diagnose errors and understand how features are used. For the one-route guest preview, we turn the IP address into a short-lived pseudonymous identifier to limit misuse; the rate-limit key does not store the raw IP address.

How we use information

We use information to provide sign-in, save user-selected places, calculate requested routes, respond to inquiries, prevent misuse, diagnose problems and improve Tomari. We do not sell personal information.

Services that help us operate Tomari

Tomari uses specialist providers for authentication, hosting, storage, email delivery, place search, route calculation and eligible booking referrals. These currently include Clerk, Vercel, Upstash, Resend, Google services, OpenStreetMap-based place search and CJ Affiliate for marked Booking.com links. Each provider handles information under its own terms and privacy practices.

When you follow a hotel, booking or activity link, the destination website may receive information in accordance with its own privacy policy. A marked Booking.com affiliate link first passes through a CJ Affiliate referral URL so the visit and any eligible commission can be attributed to Tomari. CJ Affiliate and Booking.com may receive the referral identifier, destination and technical request information under their respective privacy practices.

Information stored on your device

Your itinerary draft and interface preferences may be stored in your browser so they remain available when you return. You can remove this information through your browser settings.

Children's information

Tomari is designed for adults planning family travel. We do not ask for a child's name or other details that directly identify a child. Please do not enter such information in place searches, saved-place names or contact messages.

Retention, access and deletion

We retain information only for as long as reasonably needed for the purposes above, legal obligations, security and dispute handling. You may ask about, correct or request deletion of personal information associated with you by contacting Tomari. We may need to confirm your identity before completing a request.

Changes to this policy

We may update this policy when Tomari's features or providers change. The revised version will be published here with a new update date.

Privacy questions can be sent through Contact Tomari or to ryu.miha@gmail.com.
