Privacy policy
Established 9 November 2026. The Japanese text is the authoritative version.
The End User Computing Association (EUCA, "we") sets out below how personal data is handled on the website shinten.dev ("this site"), which we operate.
This policy covers this site. The open-source software shinten and shinten-ship run in their users' own environments; nothing they do sends us any data.
1. Operator
| Name | End User Computing Association (EUCA), a general incorporated association in Japan |
|---|---|
| Representative | Atsushi Kojo, Representative Director |
| Contact | Contact form |
2. Data we receive
- Enquiries: the name, e-mail address, organisation and message you enter in the contact form.
- Delivery records: the technical records our hosting platform (see 6) keeps to serve the site: the pages requested, times, IP addresses and browser types. We look at them only as far as investigating a fault requires.
Enquiries are forwarded to a Google Form we operate. This site's server only relays them and does not store them. What you send is stored on Google LLC's servers under Google's terms, and we read it as responses to that form.
To keep out unsolicited submissions, the time taken to fill in the form and the number of web addresses in the message are checked at the moment of sending; the values are not stored.
3. Data we do not collect
This site asks for no account, sets no cookies and uses no analytics. We keep nothing that identifies a visitor.
4. Purposes
- Answering enquiries
- Information from us related to an enquiry
- Investigating faults and keeping the site working
5. Disclosure to third parties
We do not provide personal data to third parties without your prior consent, except where the law requires it.
6. Processors
The site is served, and enquiries are relayed, on infrastructure provided by Cloudflare, Inc. Enquiries are received through Google Forms, provided by Google LLC (see 2). We supervise both as necessary and appropriate for the safe handling of personal data.
7. Cookies
This site uses no cookies, no analytics such as Google Analytics, and no advertising technology.
8. Security
We limit access to personal data to the few people who need it, encrypt communications and keep secrets apart from the rest of the system. The identifier of the Google Form that receives enquiries is not in the site's pages; it is held only in the configuration of the relaying server.
9. Your rights
Requests from you, or your representative, for notification of purposes, disclosure, correction, addition or deletion, suspension of use or erasure, or suspension of disclosure to third parties, are handled as the law provides. Please use the contact below; we act promptly once we have confirmed your identity.
10. Territory
This site is provided for customers in Japan.
11. Changes
We may revise this policy when the law or the site changes. Significant changes are announced on this page.
