Privacy at YiPhase
YiPhase is a free, experimental I Ching learning and reading website. Public account registration is currently closed. We do not request birth details or payment information.
Questions and AI readings
Time, two-number Mei Hua and virtual three-coin casts are calculated in your browser using the stated casting rules. AI does not select or change the resulting hexagram. The main Free Reading form requests an interpretation of your question when you select Start My Free Reading: your question, chosen numbers or captured moment and time zone, and the cast derived from them are sent over HTTPS to YiPhase and its third-party AI provider. On the legacy coin and moment pages, these details are sent when you choose an AI explanation. Optional clarification or follow-up requests also send the same cast and any replies you choose to provide. These steps interpret the same cast; they do not cast again. Each AI step counts toward the free allowance. Avoid identifying or sensitive personal information.
Sending information for interpretation is separate from saving a reading. The public reading flow does not save your question, optional background, cast or AI answer as a reading record in YiPhase’s server database. The server processes them to answer the request, while limited usage and connection data are handled separately below. This tab uses sessionStorage to retain the current question, cast and answer so you can refresh, open a related lesson and return. Notes are retained in this tab only when you choose to save them. These records normally end with the tab session, though a browser may restore a recovered tab. They are not an account backup or cross-device sync. Download the reading or notes to keep a longer-lived copy.
On Free Reading or Deep Reading, Clear this reading removes that flow’s saved question, cast, answer and notes from this tab. It does not remove older Reading Studio records or Learning Circle drafts. On the older studio pages, Clear this tab’s readings removes that studio’s separate temporary records. Neither control deletes downloaded files, server usage/connection records, data held by the AI provider or the other browser storage described below. Provider retention and deletion follow the provider’s policies; local clearing does not recall a request already sent. Use your browser’s site-data controls to remove the remaining local records.
Local learning marks and discussion drafts
If you choose In progress or Explored, your topic marks are stored in this browser using localStorage. They do not include a reading question or AI conversation. If you explicitly choose Save local draft only in the Learning Circle preview, localStorage retains the draft title, message, chosen audience and any reading structure you deliberately attach. Question text is included in that attachment only when you explicitly select it; AI answers and conversations are not imported. These marks and drafts remain in the same browser across visits until you remove them. They are not uploaded, posted, synced to another device or saved as account records. A private label describes an intended future audience; it is not a verified private account or protected inbox. Other people using the same browser profile may be able to see its stored drafts. You can undo or reset marks on the learning path, delete each saved draft in the circle, or remove this site's data in your browser settings. Clear this tab's readings clears the separate temporary reading records, not these learning marks or discussion drafts. Registration, verification emails and real discussion submissions are not open in this preview.
Website usage and technical data
Our hosting and Cloudflare may process IP addresses, request times, URLs and other standard connection data needed to deliver and protect the site. To improve the casting experience, our first-party analytics records page views and a random identifier for each casting attempt. For coin casts, it records completed steps, result loading, close or page-exit signals and optional one-tap exit feedback. For Mei Hua casts, it records whether the cast was started and formed or encountered an error. We also record the selected reading method and AI request outcomes. These signals can show where a flow stopped; without volunteered feedback they cannot tell us why someone chose to leave. We do not record the coin faces, question text, optional details, clarification replies, Mei Hua time zone or AI answer in analytics. We also measure navigation with a random identifier in sessionStorage that expires after 30 minutes of inactivity. It links page paths and broad game sections within this tab, classified referrers (such as Google, Pinterest and YouTube), allowlisted campaign tags, foreground-time heartbeats, outbound link categories, and game loading/casting/reading/follow-up/study/download signals. We do not store full referrer URLs, search terms, arbitrary query values, question text, cast values, AI answers, study notes or email in this navigation table; it contains no IP address. Session linkage is removed after 30 days and events after 365 days. Source tags are declarations, not proof of acquisition. Missing referrers and blocked scripts limit attribution; a last observed page, hidden tab or timeout does not establish why or where someone left. These optional browser signals respect GPC and Do Not Track and set no analytics cookie. Our private administrator dashboard can show the IP address, country, page and time of recent visits. YiPhase removes IP addresses from its analytics database after 30 days and deletes those event records after 365 days. Analytics requests contain the page path, not your question, AI answer or full URL query. We do not set an analytics cookie, and the first-party browser analytics script respects Global Privacy Control and Do Not Track signals. The server keeps temporary per-address usage counts to limit free readings and a daily total count to control costs. Our third-party AI provider and Cloudflare process data under their own policies.
Optional design preferences
The jewellery design study is not a shop. If you press “Save my preference”, YiPhase stores the selected piece, assembly, hexagram, colours, preferred purchase format, engraving preference, optional price range or amount and currency, and any suggestion or email you voluntarily enter for up to 365 days. An email is optional; feedback is saved without one. Contact details and suggestions are available only in the private administrator dashboard. Email is used to reply or follow up about the feedback or design, not to automatically subscribe you to marketing. No name or reading question is requested. This tab also temporarily retains your design selection so you can visit a hexagram guide and return; the draft is not submitted until you press the button. Your email and suggestion are not saved in this tab’s selection draft. A random identifier retained in this tab lets a repeat submission update the same preference; it is not a verified person count. The preference table does not contain an IP address or link to reading records. Standard hosting and connection logs and the separate page-view analytics described above still apply. Our private dashboard summarises preferences and keeps currencies and purchase formats separate. Please keep sensitive personal information out of suggestions. To request deletion of design feedback, contact [email protected]; if you supplied an email, include that email so we can locate the record.
Optional product enquiries
The collection currently accepts enquiries, not orders or payments. When you press “Send my interest”, we store the selected product, enquiry topic, optional message and optional email privately for up to 365 days. An email is not required. These records do not contain your IP or link to reading records. Ordinary connection logs and separate page analytics still apply. A random in-page identifier updates your enquiry if you submit again without reloading; it is not a person count. Only authorised administrators can see enquiries. Contact information is used to handle your enquiry, not to automatically subscribe you to marketing. To request deletion, contact [email protected] with the product and approximate submission time, and your email if supplied. This form does not reserve a piece or order custom work.
Future accounts
Account registration is not open. If it opens, we plan to use a verified email and a public nickname, with separate permissions for public discussions and private exchanges. Saving a reading or including its question in a discussion will remain your choice. We will not request a birthday. Your question and AI answer will not be included in saved cast history. We will update this notice before opening registration.
Your choices
You can read the guides or use the legacy casting studio without requesting an AI interpretation. The main Free Reading form sends the question and cast for interpretation when you select Start My Free Reading. If you have a privacy question, contact [email protected]. Last updated: 24 October 2026.
