This notice explains what Source-checked Japan collects, why, how long it is kept, and your choices.
Who is responsible
Source-checked Japan is an independent travel-information project operated in Japan under the site name Source-checked Japan. For privacy, access, deletion, correction, or withdrawal requests, use the contact form below. We respond within a reasonable time, normally within 14 days.
What we collect and why
| Activity | Data | Purpose | Retention |
|---|---|---|---|
| Site and CTA measurement | Page path viewed, and CTA display/click events, sent to a measurement endpoint we operate on serverless infrastructure (Twilio). No cookies, no advertising trackers, no third-party analytics services, no persistent identifiers. Email addresses and form contents are never sent to measurement counters. | Privacy-minimised aggregate measurement of what is useful. | Aggregate counters up to 12 months. |
| Yuasa map interest test | A purchase-interest click event; your email only if you separately submit it with consent. | Test demand for a proposed US$7 map. The interest test is not a purchase and no payment details are requested. | Email until unsubscribe, the decision to release or not release the map, or 6 months after signup, whichever comes first. |
| Mt.FUJI100 2027 alert | Email, signup source and version, and your consent record. | Send the requested official-update alerts, based on consent. This is an independent alert, not an official race-organizer service. | Until unsubscribe or 90 days after the 2027 event. |
| Privacy / correction contact | Your message; your email only if you include it for a reply. | Respond to your request and fix errors. | Kept with the request log; deleted on request once resolved. |
Submitted emails are stored on infrastructure we control (Twilio Sync, processed under Twilio's data processing terms) and are not shared with, or sold to, any third party.
