Privacy Policy

1. Data we collect

• Account: email address, name, phone number, and an encrypted form of your password. We never store your password in readable form.
• If you sign in with Google, Apple or LINE, we receive your email address, name and a provider user ID from that service. We do not receive your password.
• Bookings: pick-up and drop-off location and time, vehicle class, rental period, optional extras, insurance tier and the amount charged.
• Payment: card payments are processed by Stripe. We never see or store your full card number. We keep only the identifiers Stripe returns to us so we can match payments and issue refunds.
• Technical: IP address, browser type and access time, kept in server logs for security purposes.

2. Why we use it

• To create and manage your account, and to let you sign in.
• To process bookings, payments, refunds and deposits.
• To send transactional email: booking confirmations and password resets. We do not send marketing email without your consent.
• To pass the minimum information a partner store needs in order to hand over the vehicle — your name, contact details, and booking details.
• To prevent fraud and abuse, and to meet our legal and accounting obligations.

3. Who we share it with

We do not sell your personal data. We share it only with:

• Partner rental stores, limited to the booking you made with them.
• Stripe, for payment processing.
• Cloudflare Turnstile, for bot protection on sign-in and sign-up forms.
• Google Maps, when a page displays a map. Google may receive your IP address.
• Travel agencies and booking platforms, only where you booked through them.
• Authorities, where we are legally required to do so.

4. International transfer

Our servers and some of the services above are located outside Japan. By using our services you understand your data may be processed in those countries under appropriate safeguards.

5. How long we keep it

Account data is kept while your account is active. Booking and payment records are kept for the period required by Japanese tax and commercial law. You may ask us to delete your account; records we are legally required to retain will be kept until that period expires.

6. Your rights

You may ask us to show, correct, delete or stop using your personal data, and to withdraw a consent you gave. Write to us at the address below and we will respond within a reasonable period after verifying your identity.

7. Cookies

We use cookies that are necessary for the service: keeping you signed in, remembering your language, and completing payment. We do not use advertising cookies. Blocking these cookies will prevent sign-in and booking from working.

8. Documents shown at pick-up

At pick-up the store checks your passport, driving licence or International Driving Permit, and a credit card. These are verified in person by the store. Where a store records them, it does so as the party responsible for that record.

9. Children

Our service is for adults who hold a valid driving licence. We do not knowingly collect data from children.

10. Changes

We may update this policy. The current version and its date are always shown on this page.
