Privacy Policy

Last updated: November 2026

WoFu (“the Platform”) values and is committed to protecting your personal privacy. This Privacy Policy explains how we collect, use, disclose and store your personal data when you use the Platform’s website and mobile app services. Please read it carefully before using the Platform.

1. Information we collect

When you use the Platform, we may collect the following types of personal data:

Account data: email address, password (stored encrypted), and linking information for third-party accounts such as LINE, Google or Kakao.

Chart data: name, date of birth, time of birth, place of birth, and sex. A chart may be your own or one you created for someone else (see the next item).

Other people’s chart data: the name, sex, date of birth, time of birth and place of birth you enter when you create a chart for a family member, friend or other person, or when you use synastry, birth-time selection or an expert reading. For birth-time selection, the candidate data is a planned date and time of birth. You should provide this only after obtaining that person’s consent (see section 6 of the Terms of Service).

Synastry settings: the relationship type, the current status of the two people, and whether the adult intimacy compatibility analysis is enabled. The intimacy analysis is off by default; the system processes that content only when you enable it, the relationship type is romantic, and both people are 18 or older.

Background details: the occupation, description of your work, relationship status, family situation and notes you choose to provide. These are sent to the AI as context for your reading, and you can edit or clear them at any time from the chart editor.

Consultation content: the questions you put to the AI reader and the conversation history. So that later conversations keep their context, we also store a summary of your background that the AI compiles from those conversations.

Card questions and readings: the question you enter in Zi Wei cards, the cards drawn by the system, the AI reading and your follow-up questions. The system automatically classifies each question by topic (such as relationships, career or money) for statistics and to improve reading quality; when the same account asks a similar question within a short period, the system also compares it with your past questions to let you know.

Expert reading data: the questions you submit to the astrologer, the chart you specify for the reading, and your display name on the Platform’s official LINE account; the conversation in which the astrologer replies through official LINE is also kept.

Analysis feedback: the ratings and comments you submit about analysis reports.

Payment information: transaction records when you purchase paid services. The Platform supports several payment methods (credit card, ATM transfer, convenience-store payment, mobile payment, cryptocurrency, etc.); actual payments are handled by third-party payment providers (ECPay, NewebPay, JKOPAY, PayPal, NOWPayments, etc.), and the Platform does not store your credit card number.

Rewards and referral data: your member points records and referral (invitation) relationships.

Usage records: your browsing history and feature usage on the Platform.

Device information: device type, operating system, browser type, and IP address.

Push notification identifier: if you allow notifications in the mobile app, we store your device push identifier, language preference and app version so that we can tell you when a reading is ready. It stops working when you turn notifications off or sign out.

Customer support messages: the messages you send us through in-app support, together with the reference to the reading or order you are asking about.

Advertising attribution data: when the app is first opened, it asks Apple whether this install came from an advertisement we placed on the App Store. The answer — whether it came from an ad, and the campaign identifier — is linked to your account and used to measure marketing performance. This query does not read your advertising identifier (IDFA) and is not combined with any third-party data.

In-game rewarded ads: in the app's life-simulation game, a rewarded ad provided by Google AdMob plays only when you choose "Watch an ad for ten more years". When an ad plays, Google may collect a device identifier, approximate location (estimated from your IP address), ad interactions and diagnostic data such as crashes, to serve and measure ads. The app does not ask for tracking permission, so Google cannot obtain your advertising identifier (IDFA). If you never choose to watch an ad, no ad is loaded.

2. How we use your information

We use the personal data we collect for the following purposes:

To provide Zi Wei Dou Shu chart casting, AI analysis, AI chat, synastry, birth-time selection, Zi Wei cards and expert reading services.

To create and manage your member account.

To process your orders and payments.

To send service notifications, order confirmations and important system announcements.

To let the Platform’s astrology staff review questions, card spreads and readings in order to calibrate the quality of AI interpretations.

To improve and optimize the quality of our service and the user experience.

For statistical analysis and market research (handled in de-identified form).

To comply with applicable laws and respond to lawful requests from government authorities.

3. How we protect your information

The Platform takes appropriate technical and organizational measures to protect your personal data, including:

Using the HTTPS encrypted transport protocol.

Storing passwords with industry-standard encryption algorithms.

Credit card details are entered on and handled directly by the payment pages of third-party payment providers (ECPay, NewebPay, JKOPAY, PayPal, etc.); they never pass through or get stored on the Platform’s servers.

Restricting the personnel authorized to access personal data.

Card questions and readings, and the questions and charts submitted for an expert reading, are viewed by the Platform’s astrology staff to deliver the service or calibrate reading quality; everyone with such access is bound by confidentiality obligations and accesses only what is necessary.

Reviewing our data security measures regularly.

4. Disclosure and sharing

Except in the following cases, the Platform does not provide your personal data to third parties:

With your consent: where we have obtained your explicit consent.

Service providers: partners we must engage to deliver the service (such as payment and cloud providers), all of whom are bound by confidentiality obligations.

AI service providers: readings, the AI consultation, synastry, birth-time selection and Zi Wei card readings are produced by third-party large language model services (OpenAI, Anthropic). To do that, the relevant chart data (including charts you created for other people), the background details you provide, your synastry settings, and the content you enter in chat and card questions are sent to those providers for processing. Under their enterprise API terms these providers do not use your data to train their models. These services are located outside Taiwan.

Life-simulation game: game characters are fictional and generated at random. When a life begins, the character's randomly generated birth details are sent to an AI service provider to write the character's "Nature" description; when you buy a "Life story", the events and choices from that game are sent to an AI service provider to write a short story. Neither includes your own name, birthday or other personal data, and the game does not require an account.

Astrologers: when you purchase an expert reading, the chart you specify (including its background details), your questions and your LINE display name are provided to the astrologer who replies. The astrologer is either Platform staff or a partner astrologer bound by confidentiality obligations.

Apple (refund review): if you ask Apple for a refund on an in-app purchase, Apple asks us what that order actually delivered. We reply with how much of it was delivered, its delivery status, and our recommendation on the refund. The reply covers only the delivery facts of that one order — it carries no name, chart data or report content. By completing an in-app purchase you consent to us providing this information for refund review.

Legal requirements: as required by law, a court order, or a lawful request from a government authority.

Protection of rights: to protect the rights, property or safety of the Platform, its users, or the public.

5. Personal data provided by someone else

If your name and birth details were entered by another user of the Platform (for example a family member, friend or partner) to create a chart, run a synastry or book a consultation, the Platform processes that data on the basis of that user’s representation that they obtained your consent.

The data is managed by the person who created it and is deleted together with their account.

You may use the contact details in section 11 of this policy to request access to, correction of, or deletion of data about you; we will act after verifying your identity and may also delete the analysis content produced from it.

The Platform will not contact you on its own initiative and will not disclose the data to anyone other than the person who created it.

6. Use of cookies

The Platform uses cookies and similar technologies to:

Keep you signed in.

Remember your preferences.

Analyze site traffic and usage.

Improve site performance and user experience.

You can manage or refuse cookies through your browser settings, but this may affect your experience of certain features of the Platform.

7. Your rights

Under Taiwan’s Personal Data Protection Act, you have the following rights:

To inquire about or request access to your personal data.

To request a copy.

To request supplementation or correction.

To request that we stop collecting, processing or using it.

To request deletion.

To exercise these rights, please contact us using the details below. We will handle your request within a reasonable period.

8. Data retention and account deletion

We retain your personal data for as long as necessary to fulfill the purposes for which it was collected.

Charts, analysis reports, chat and card history, and synastry and birth-time data are kept for as long as your account exists so that you can revisit them at any time.

After you request account deletion, the account enters a 30-day retention period; signing in during that period restores it. Once the period ends, the account and everything under it (including charts you created for other people and expert reading records) are permanently deleted.

Where the law requires otherwise (such as tax record-keeping obligations), those records are retained in de-identified form for the statutory period.

How to delete your account:

In the app (iOS / Android): open WoFu, go to “Me”, open your account settings and tap “Delete Account”, then confirm on screen

On the website: sign in at wofu-studio.com, then go to “Settings” → “Security” → “Delete Account”

If you cannot sign in: email support.wofu@wofu-studio.com from the address you registered with, with the subject “Account deletion request”; we will verify your identity and delete the account for you

9. Protection of minors

The Platform does not knowingly collect personal data from children under 13. If you are a minor under 18, you should use the Platform with the consent of your legal guardian. The adult intimacy compatibility analysis in synastry can be enabled only when both people are 18 or older. The candidate data processed for birth-time selection is the planned birth time of a child not yet born, provided by a parent or legal guardian.

10. Changes to this policy

The Platform may revise this Privacy Policy at any time. The revised policy will be posted on this page with an updated “Last updated” date. For material changes, we will notify you by appropriate means. Continuing to use the Platform after a revision constitutes your acceptance of the revised policy.
