Privacy Policy

1. Who we are

Echo of Zhongnan · 终南回响 is operated by Waajii Technology Limited · 哇嘰網絡科技有限公司, a company registered in Hong Kong (Unit 2100A, 21/F, One Pacific Centre, 414 Kwun Tong Road, Kwun Tong, Kowloon, Hong Kong). Waajii Technology Limited is the data controller for this website. You can reach us at any time at support@waajii.com.

2. What we collect

• Reading inputs. To cast a chart we ask for a birth date, and optionally a birth time, birth city, name and gender. For compatibility readings you may enter a second person's details — only after confirming you have their consent.
• Contact details. If you email us, we receive your email address and the contents of your message.
• Order details. When checkout opens, an order includes your name, shipping address, email and the items purchased. Card numbers are handled by our payment provider and never touch our servers.
• Technical data. Your IP address is used transiently for rate limiting and security. We use privacy-friendly, cookieless analytics (Vercel Analytics) that count visits without identifying you.

3. How birth data is handled

Birth details are sensitive, and we treat them that way:

• Your inputs are sent to our server over HTTPS to calculate the chart and to generate the written reading with a third-party AI language model provider acting as our processor. Only the data needed for the reading is sent.
• Reading inputs are not written to a database and are not retained after your result is delivered. A short-lived, in-memory cache may hold a result for minutes so a repeated identical request does not incur another AI call; it disappears when the process restarts.
• We do not sell personal data, do not use birth data for advertising, and do not build profiles from it.
• If you would rather not give your full name, a first name or initial is enough — the reading works the same.

4. Newsletter

The newsletter form on this site is currently a placeholder and does not transmit or store your address. When email delivery begins, your address will be stored with an email service provider, used only for the letters you asked for, with double opt-in and one-click unsubscribe.

5. Your basket

The shopping basket is stored in your own browser's local storage. It never leaves your device until you check out.

6. Retention

• Reading inputs: not retained after the response is delivered.
• Correspondence: kept while your enquiry is active, then removed on request.
• Order records: kept as required by Hong Kong accounting and tax law once the shop begins charging.

7. Your rights

Depending on where you live (including Hong Kong under the PDPO, and the EEA/UK under the GDPR), you may have the right to access, correct, export or delete your personal data, and to object to or restrict processing. Email support@waajii.com and we will answer within seven days. Because readings are not stored, most reading data no longer exists by the time you ask.

8. Children

This site is intended for adults (18+). We do not knowingly collect data from children.

9. Changes to this policy

If we change how data is handled — for example when accounts, saved charts or paid reports are introduced — we will update this page and its date before the change takes effect.
