Privacy Policy
Last updated: September 28, 2026
This policy explains what One Question, One Hexagram (一事一卦) (the "Service") collects and why.
1. Your questions stay on your device
Readings are computed in your browser. The question you type, your reading history and your "did it come true?" answers are stored only in your browser's local storage. We do not send them to our servers and cannot see them. You can delete them at any time by clearing your browser's site data.
2. Payments
If you buy a reading or a subscription, checkout is handled by our payment partner, which acts as Merchant of Record. It collects your name, email, billing country and payment details to process the payment, calculate tax and send receipts, under its own privacy policy. We receive order information (such as email, product, amount and country) to provide access and support. We never see or store your full card number.
3. Technical data
Our hosting provider may keep standard server logs (such as IP address, browser type and time of request) for security and reliability. The page loads a 3D library from a public CDN (cdnjs.cloudflare.com), which receives standard request data. We do not use advertising trackers and we do not sell personal data.
4. Your rights
You may ask us to access, correct or delete personal data we hold about you (for example, order records) by emailing mufmo130@gmail.com. Depending on where you live, you may have further rights under laws such as the GDPR or Korea's Personal Information Protection Act.
5. Children
The Service is not directed to children under 14, and paid features are for adults.
6. Changes and contact
We will post changes on this page. Contact: mufmo130@gmail.com
