Privacy Policy

This policy explains how YUDING (the "App", "we", "us") collects, uses, stores and shares your information when you use the App and this website, yudingempire.com, and what rights you have. Please read it in full before using the service.

1. Operator and contact

The App is operated by [TO FILL: legal company or developer name], registered at [TO FILL: registered address].

Privacy enquiries: support@yudingempire.com

2. Information we collect

2.1 Account information

There are four ways to sign in, and we receive accordingly:

• Email sign-up — your email address. Passwords are hashed and held by Firebase Authentication; we never see them in plain text.
• Phone verification — your phone number including country code.
• Google Sign-In — your Google account identifier, email and avatar.
• Sign in with Apple — the identifier Apple provides. If you choose to hide your email, we only receive Apple's private relay address.

2.2 Profile information

Display name, English name, gender, birthday, avatar, cover image, bio, region, YuDing Code (member number) and verification status. You enter these yourself, can edit them at any time in the App, and can keep certain fields anonymous.

2.3 Birth data for charting

To compute a chart we collect your birth date (solar or lunar), birth hour or exact birth time, birth region (used for true-solar-time correction) and gender, plus the relationship label and name you enter when creating a profile for someone else.

You may create profiles for family and friends. Please obtain their consent before entering another person's birth data; you are responsible for the lawfulness of the third-party information you submit.

2.4 Usage and content

• Chart and plate history, generated reports, browsing history
• Direct messages and images you send
• Posts you publish
• Friend relationships, following lists and block lists

2.5 Transaction information

DCC balance and spending history, gifting records, shop orders and pickup numbers. We do not collect or store your card number, CVV or payment password — payment is handled by the Apple App Store and we only receive whether a transaction succeeded.

The e-wallet labels saved under "Payment" in the App are a demonstration feature: they store only the label you type, connect to no real payment channel, and contain no credentials that could be charged.

2.6 Device permissions

All of the following are optional; declining affects only the related feature:

2.7 Technical information

Device model, OS version, App version, language setting, push token, crash logs and basic usage statistics — used for troubleshooting and improving the service.

3. How we use this information

• Computing charts and plates, and generating the corresponding readings
• Creating and managing your account, identity and YuDing Code
• Providing social features: friends, messages, posts, following and blocking
• Issuing, spending and gifting DCC, and processing shop orders
• Sending notifications relevant to you (report ready, messages, friend requests)
• Synthesising read-aloud audio for reports
• Translating the interface and report text into your chosen language
• Troubleshooting, preventing abuse and fraud, and keeping accounts secure
• Meeting obligations under applicable law

4. Third-party services

We rely on the following providers to run the App. Their own privacy policies govern the data they process:

5. Storage and retention

Data is stored on Google Cloud servers in Singapore (asia-southeast1). Because our providers operate global infrastructure, data may transit other countries or regions during transmission and backup; we require providers to maintain protection comparable to this policy.

Retention: your account and birth profiles are kept while the account exists; deleting a report or profile removes it from ordinary storage. After account deletion we erase or anonymise your personal data within a reasonable period, except transaction records we are legally required to retain.

6. Sharing

We do not sell your personal information. We share it only:

• Content you choose to make public — display name, avatar, bio, posts and messages you send, visible to other users within the scope you choose
• With the providers listed above, to the extent needed to deliver the service
• Where required by law, in response to a lawful request from a competent authority
• To protect rights, to prevent fraud or abuse, or to protect the safety of users and the public
• In a business transfer — on a merger or transfer of assets we will notify you in advance, and the recipient must honour this policy

7. Your rights

• Access and correction — view and edit your profile and birth data under Me → Edit Profile
• Deletion — delete individual reports, posts, messages and birth profiles
• Account deletion — start deletion under Settings → Account & Privacy; your account and associated data will be removed. This is irreversible, and any unused DCC is forfeited
• Withdrawing permissions — turn off camera, photos, location, microphone and notification access in iOS Settings at any time
• A copy of your data — write to us for a copy of the personal data we hold about you
• Complaints — if you believe we have handled your data improperly, contact us, or complain to the data protection authority in your jurisdiction

To exercise these rights, email support@yudingempire.com. We reply within 30 days of receiving a request.

8. Children's privacy

The App is not directed at children under 13, and we do not knowingly collect their personal information. If you are a guardian and believe your child has given us information without consent, please contact us and we will delete it promptly.

9. Security

We protect data with encryption in transit (HTTPS/TLS), access control through Firebase security rules, and server-side secret management. Please understand that no method of internet transmission or storage is completely secure, and keep your account credentials safe.

10. Cookies on this website

yudingempire.com is a static site. It uses no tracking cookies and loads no third-party advertising or analytics scripts. We store only your chosen display language in your browser's localStorage; that value is never sent to us.

11. Changes to this policy

When this policy changes we update the "Last updated" date at the top of this page, and for material changes we will prominently notify you inside the App. Continued use means you accept the updated policy.
