1. What never leaves your device

Your name, sex, birth date, birth time, birth place and any partner’s details entered for a compatibility reading are stored only in your browser (localStorage) and are never transmitted to the operator. All calculations run in your own device in JavaScript.

The operator therefore cannot know what birth date you entered or what result you saw. Clearing this site’s data in your browser removes it all.

2. Personal data we do collect

Exactly one item: an email address, and only if you choose to sign up for the VIP launch notice. It is used to tell you when paid features open and to gauge demand, kept until that notice is sent or the service ends, and deleted immediately on request.

Submitted emails are not stored in any database. Only a masked form (e.g. ab***@example.com) and an irreversible hash for counting duplicates are written to server function logs.

3. Cookies and advertising identifiers

The site carries advertising to cover running costs. Google AdSense and Kakao AdFit may set cookies or use advertising identifiers, and your IP address and browser information may be transmitted to them. You can turn off personalised ads at Google Ad Settings or opt out of third-party advertising at aboutads.info. Refusing advertising cookies does not affect your use of the site.

4. Processors and international transfers

• Cloudflare, Inc. (USA) — hosting and delivery; access logs including IP are processed transiently.
• Google LLC (USA) — advertising (AdSense) and web fonts; your IP is sent when fonts are requested.
• Kakao Corp. (Republic of Korea) — advertising (AdFit).

Planned feature: if the “Master Cheonman” generative reading is launched, the question you type and the chart figures shown on screen would be sent to Anthropic PBC (USA) to generate an answer. This feature is not currently offered, and this policy will be updated before it is.

5. No sale or sharing

We do not sell or share your personal data with third parties, except where lawfully required by an authorised investigative authority.

6. Your rights

You may request access, correction, deletion or suspension of processing at any time. Data held in your browser can be removed by you directly through your browser’s site-data settings, or re-entered via ‘Edit details’ at the top of the page. For deletion of a VIP notice email, write to the contact below.

7. Children under 14

We do not collect personal data from children under 14. If you are under 14, please do not use the VIP notice sign-up. All other features collect no personal data.

8. Security

The whole site is served over HTTPS. We minimise risk by design — personal data is not stored on the server, and collected emails are recorded only in masked and hashed form.
