1Who We Are

TIANJI AI STUDIO PTE. LTD. (UEN 202605294Z), of 141 Cecil Street #08-07, Tung Ann Association Building, Singapore 069541, runs TianJi and is the controller of the personal data described here. This Policy applies wherever you live and should be read with our Terms of Service. Write to admin1@tianjiaistudio.com about anything in it.

Currency and languageYour IP address, sent to an IP-location service so prices show in your own currency; the language you use the app inYour device
PurchasesMinutes bought and held, and the store's purchase record. We never see your card numberGoogle Play or the Apple App Store

Some of this is sensitive — what you tell the Master about your health or your relationships, or a face photo. We process it only to give you what you asked for, with your consent.

3What We Do With It

  • Readings and consults: calculating charts, writing and speaking the Master's replies, running live sessions (contract; consent for photos and voice).
  • Your evolving profile: short memories of your situation, goals and concerns, so the Master applies the Arts to your life rather than in general (consent). It does not replace the Arts.
  • Relationship insight between connected people, and personalising the app and, in future, recommendations such as products and dating matches (consent).
  • Social features: Circle, Discover including Dating, Messages, calls, blocking and reporting (contract).
  • Translation into your language — section 4 (contract).
  • Purchases of live minutes, and the records tax law makes us keep (contract; legal obligation).
  • Prices in your currency: the country your IP address is in, and the day's exchange rate (legitimate interests).
  • Keeping TianJi working and safe, and our own first-party analytics, which never records what you wrote (legitimate interests; legal obligation).

We do not sell your personal data. We do not use your conversations to train AI models, and we send them to our AI providers only to produce the reply you asked for. There are no third-party analytics, advertising or tracking services anywhere in TianJi.

4Automatic Translation

TianJi shows you other people's messages, and the Master's earlier replies, in the language you have chosen for the app. Exactly how that works:

  • What is sent. The text of a one-to-one message someone else wrote to you, or of an earlier reply from the Master, goes to BytePlus ModelArk to be translated. Nothing goes with it — not your name, not your chart, not your account.
  • What is not. Your own messages are not translated for you, photos and voice are not translated, and nothing is translated for anyone who is already reading in the language it was written in.
  • What is stored. We keep the translation beside the original, so the same text is not translated twice, and we note which language the original was in. The original is always kept, Show Original brings it back, and translations are deleted when the message, the consult or your account is.

A machine translation can be clumsy or plainly wrong, so the original is always there to check.

5Other People, and Children's Charts

A consult can be about one person you found in Discover, or up to four of your Circle connections. The Master is given their name, a digest of their chart and your compatibility — only where their own visibility settings allow it, and never across a block. Their details and what you said about them are stored in your account with the Master's readings, visible only to you. Please only add people whose details you are entitled to share; you can delete a person or a consult at any time, and if someone asks us to remove their information, write to us.

Relationship insight. When two people are connected, what the Master learns about the relationship from one of them may shape the guidance it gives the other — never revealed, quoted or attributed. Health, money and debts, sexuality and affairs, legal matters and anything said in confidence are never used this way. It stops when the connection is removed or either person withdraws consent.

Children's charts. An adult may add a child's chart after confirming they are the parent or guardian, or have permission; we record that confirmation and its wording with the chart. The chart is read-only: no login, never in Discover, Dating or Messages, never in the anonymous library in section 12, never sent to analytics. Delete it at any time, and it goes when your account goes.

6Live Sessions, Face and Palm Readings

In a live session your voice goes to BytePlus: RTC carries it, Seed-ASR turns it into text, ModelArk composes the reply and Seed-TTS speaks it back. When the animated avatar is on, Akool renders the Master's video from that reply. We keep the written turns as part of your consult history. We do not store the audio — it exists only while it is being carried and recognised. Your camera is never used, and there is no camera button in a Master session.

For a face or palm reading, the photo goes to BytePlus ModelArk's vision model, which describes what it can see. We store the photo, a fingerprint of it so it is not read twice, the list of features, and the reading written from them. That list is narrowed first: anything the model says about health, ethnicity, attractiveness, age or disability is removed and never reaches the Master or your profile. Delete the reading and the photo goes with it.

7Who Else Sees It, and Where It Is Held

These providers process data for us, under contract, only as far as running TianJi needs:

ProviderWhat forWhat they get
ClerkSign-in and account securitySign-in details, device and IP information
BytePlus ModelArkThe models that write the Master's replies, read face and palm photos, and translate messagesConsult content, charts, relevant profile context, photos you submit for a reading, message text to translate
BytePlus Seed-ASR, Seed-TTS and RTCHearing you, speaking back, carrying the live sessionYour voice during a live session; the Master's reply text; session identifiers

Google FontsThe typefaces the app is set inYour browser asks Google for the font files, which tells Google your IP address and browser. This happens in the app, not on this page

Where it is held. We are a Singapore company, but TianJi's data is stored in the United States — our servers, database and files are hosted by Railway in US West (California). BytePlus processes through its Asia-Pacific (Southeast) endpoints; Clerk and Akool also process outside your country. So your personal data leaves Singapore, Thailand or Vietnam, and when we move it we use contractual protections requiring a standard of care comparable to your local law.

Other users see only what you choose to show them. We may also disclose data where the law requires it, to protect someone's safety, or as part of a business transfer, in which case this Policy follows it.

8How Long We Keep It

  • Your account, charts, profile, consults, memories and photos: while your account exists. We never delete an account for being inactive.
  • When you delete your account: all of that goes from the live service straight away, and out of our host's rolling backups within 90 days (daily for 6 days, weekly for 27, monthly for 89). Session audio was never stored at all.
  • Messages, chat media and translations: until deleted; the copy the other person holds stays with them. A message you delete disappears for both of you at once and is purged from our systems within 90 days, or 90 days after a safety review if a report still points at it.
  • Reports, blocks and safety records: kept indefinitely, so a report still means something and a block still holds after an account goes.
  • Purchase records: 5 years, which is what Singapore tax and company law requires.
  • Usage analytics: pruned after 180 days.
  • Anonymous copies of conversations: kept indefinitely. They carry no identifier, so account deletion cannot reach them — section 12.

9Your Rights, and What Delete Account Removes

You can ask for a copy of your data, correct it (birth details are editable in the app), delete it, or object to a particular use. Email admin1@tianjiaistudio.com; we answer within the time your local law requires, usually inside 30 days.

Delete Account really deletes — straight away and for good: your birth details and charts, every consult and turn in it, live session transcripts, memories, readings, every photo including palm and face, your connections and the charts you added, your dating profile with its likes and passes, your minutes and jade grade, your analytics rows, your settings, and your sign-in account with Clerk. Other people's ties to you go too. Four things stay, on purpose:

  • A conversation another real person is part of. Their copy stays with them. Your account row becomes an anonymous marker — no name, no email, no photo, sign-in impossible — and they see "Someone".
  • Blocks other people made against you, so a blocked chat stays hidden for whoever blocked it.
  • Reports, safety records and purchase records, as section 8 says.
  • Anonymous copies of conversations, which hold nothing that identifies you.

Withdrawing consent. In Profile & Settings, or by email, you can switch off the Master learning from new conversations and using your stored memories (we delete them on request), relationship insight to and from your connections, and personalised recommendations. Readings from your birth chart still work, they are simply less personal. Withdrawing consent to everything means we cannot run the service for you, so we would close your account. Withdrawal does not undo what happened before it.

10Adults Only

You must be 18 or over to have a TianJi account, and we do not knowingly collect the personal data of anyone under 18. There is no teen mode and no children's version. A child's chart added by an adult (section 5) is not an account: the child cannot sign in and never appears socially. If you think a child has given us data, tell us and we will delete it.

11Security

We use encryption in transit, access controls and reputable providers. No system is perfectly secure. If a breach affects you, we will tell you and the authorities as the law requires.

12Helping Us Improve the Master

When a conversation with the Master ends, or a face or palm reading is produced, we keep an anonymous copy so we can check the quality of its answers and improve them. Switch it off at any time with Help Improve the Master in Profile & Settings.

First we take out names — yours, anyone you mention — along with places, dates, birth details, email addresses, phone numbers, handles and links, and put neutral markers such as <name> in their place. The copy carries no account identifier of any kind, and no time more precise than the day. With it we keep only what describes the reading rather than you: the elements and strength of the chart, the luck pillar, the Zi Wei bureau, your age in a five-year band, your gender, your app language, your country, the Master's short notes on temperament and situation, and simple quality signals such as how long the conversation was.

Because they hold no identifier, these copies cannot be traced to you, retrieved by you, or removed on request — including when you delete your account. That is also what makes them safe to keep: deleting your account still deletes everything that is yours. Switching off stops new copies being made. We do not sell, publish or share them.

13Singapore, Thailand and Vietnam

Singapore (PDPA 2012). We act with your consent or as the PDPA otherwise permits. Our Data Protection Officer is at admin1@tianjiaistudio.com, and the Personal Data Protection Commission hears complaints if our answer does not satisfy you.

Thailand (PDPA B.E. 2562). We rely on your explicit consent for sensitive data such as face images, and on contract, legitimate interests or legal obligation for the rest (section 3). You have the rights to access, a copy, portability, objection, erasure, restriction, correction and withdrawal, and may complain to the Personal Data Protection Committee.

Vietnam (Decree 13/2023/ND-CP). This Policy is our notice of processing: purposes (section 3), data including sensitive data (section 2), recipients (section 7), retention (section 8), and the risk that disclosure of sensitive data would cause harm, which section 11 reduces. We process only on your consent, given by an affirmative act such as ticking the agreement box and withdrawable at any time. Write to us to exercise your Decree 13 rights, or complain to the competent authority.

14Changes and Contact

Each version carries a version number and dates at the top. When we change something material we show you a summary in the app and ask you to agree before you carry on, and we give at least 14 days' notice unless the change is urgent for safety or the law. We record which version you agreed to, and when.
