Privacy Policy (English)

This is a reference translation. The Japanese text above is the binding version; if the two differ, the Japanese prevails.

1. Operator. Yuya Miyajima (sole proprietor), Oe Building B1, 3-4-5 Ikejiri, Setagaya-ku, Tokyo 154-0001, Japan. Contact: info@caravanclass.com.

2. What we collect. From the host (a member who receives scheduling requests): their LINE user id (an identifier only — we do not take the name or profile picture held by LINE), the display name and contact email they enter, the events in the calendars they connect (start, end, title, location, and whether an online meeting link exists), the text of the scheduling rules they write, and usage records (sign-in time, IP address, browser type). From the guest (a person requesting a time): name, email address, optional company or organisation, the subject of the meeting, optionally how they heard about the host, and the record of the request (time, IP address, browser type). We never receive or store card numbers or any other payment details — the service takes no payments.

3. Why we use it. To compute the times the host is genuinely free and show them to the guest; to notify the host of a request and send the approval or decline; to create the approved appointment in the host's calendar; to confirm CARAVAN membership; to prevent abusive or fraudulent requests; and to answer enquiries.

4. Calendar events. We read the host's calendars only to work out which times are free. The guest sees free times only — never event titles, locations or attendees. Events read during a computation are not kept in a form that can be read back; only the resulting free times are stored, for a limited period. A single event is written to the host's calendar only when the host approves a request. A host can disconnect a calendar at any time from their own screen, after which we stop reading it.

4-2. Google user data (Limited Use). Information received from Google Calendar is handled in accordance with the Google API Services User Data Policy, including the Limited Use requirements. Specifically: it is used only to provide the features of this service (computing free times and creating an approved appointment); it is never used for advertising, profiling or targeting; it is never sold or transferred to third parties; no human reads it, except (a) with the user's explicit consent, (b) where necessary for security or to comply with the law, (c) where it is aggregated and anonymised, or (d) when investigating a fault at the user's request; events read are not retained in a readable form; and it is never used to train or improve machine-learning models. Access can also be revoked from Google account settings.

5. Disclosure to third parties. We do not provide personal information to third parties except where required by law. A guest's name and message are passed only to the host they wrote to.

6. Processors and external services. The external services used to run this service, the items sent to each, and the purpose, are listed on our external transmission page. Some of these providers are located in the United States and elsewhere, so personal data is transferred outside Japan; that page also describes the legal regimes of those countries and the measures those providers take.

7. Security. The credentials used to reach a calendar are stored encrypted. Each host's data is separated so that one host cannot reach another's. All traffic is encrypted in transit. Access is limited to the operator, and is logged.

8. Retention. We aim to erase data automatically on roughly this schedule. The contents of a scheduling request (name, email address, organisation, message) and the IP address and browser type recorded with it: 180 days after the meeting date. Copies of notification emails (recipient, subject, body): 14 days; approval and cancellation links in those copies are masked when the email is sent. IP addresses in activity records: 90 days. Sign-in sessions: until sign-out, and at most 30 days. A host's settings and rules: until the host asks us to delete the account. If a host is no longer a CARAVAN member, the page is unpublished and sign-in stops working at once; about 30 days after we confirm this, we ask Google and Zoom to revoke access and then delete the stored credentials, unless the host has rejoined in the meantime. Backup copies kept for recovery may hold data for a while after these periods; only the operator handles them.

9. Your rights. You may ask us to disclose the personal data we hold about you, to correct, add to or delete it, to stop using or erase it, or to stop providing it to third parties. Write to info@caravanclass.com. After confirming your identity we act without delay, at no charge.

10. Cookies. We use cookies to keep a host signed in, and a short-lived cookie (15 minutes) to confirm that a calendar or Zoom connection is completed in the same browser that started it. We do not use them for advertising or behavioural tracking.

11. If a breach occurs. If personal data is leaked and there is a significant risk of harm to an individual's rights or interests, we report it to the Japanese Personal Information Protection Commission and notify the people affected.

12. Reporting a vulnerability. If you find a security problem, please write to info@caravanclass.com. See our security page for details.

13. Changes. When we change this policy, we publish the change on this page.
