Privacy Policy

1. What we collect for a reading

• Birth date (year, month, day), for the year, month and day pillars.
• Birth time (optional). If unknown, we read the three pillars we can calculate.
• Birth place (city and country), for the longitude used in local solar time.
• Sex, because classical BaZi counts the ten-year cycles (Da Yun, 大运) forward or backward depending on it and on the year stem.
• Email address, to deliver your reading and order messages. Checkout runs through Stripe.

2. The free Element Check

The Element Check calculates in your browser. The birth date and time you type there are not sent to us or stored by us.

3. Email notes and waitlists

If you give us your email on the Element Check or the Companion waitlist, we store that address, which form you used and when, so we can send the notes or the waitlist update you asked for. Every email has an unsubscribe link, and you can also write to us. We don't use these addresses for anything else.

4. What we use it for, and what we don't

Birth details are used only to calculate and write your reading. We do not sell, rent or share your information with data brokers, and we do not use your personal information or charts to train public AI models.

5. Payments

Payments are processed by Stripe. We never receive or store your card number or bank details.

6. Cookies and analytics

This site does not set advertising or tracking cookies. If we add site analytics, we will use a cookie-free, aggregate tool and name it here first.

7. Retention and deletion

We keep the birth details for an order for 30 calendar days after delivery, so we can handle rewrites and refunds, and then delete them. You can ask for deletion at any time: email > with the subject “Data Deletion Request”.

8. International transfers and your rights

TangoEra is operated from Hong Kong and uses international cloud services for calculation, hosting and email, so your data may be processed outside your country. Depending on where you live (for example under the GDPR or California law), you can ask to access, correct or delete your data, or object to how we use it. Write to >; we reply within the time the law requires.

9. Contact and changes

RhinoNexus Tech Limited, Unit 135, 1/F, 143 Wai Yip Street, Kwun Tong, Kowloon, Hong Kong. If we change this policy, we update the date at the top of this page.
