Privacy Policy - Celestine

1. Introduction

Celestine ("we," "our," or "us") is operated by AIVANA PTE. LTD. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use the Celestine mobile application and related services (the "App"). By using the App, you consent to the practices described here. If you do not agree, please discontinue use.

2. Information We Collect

Account information: email address, hashed password, display name, profile photo, language preference, and login/session data.

Birth and profile data: date of birth, time of birth, place of birth, gender, calendar preference, and the questions or details you choose to provide for readings and charts.

Orders and master services: services selected, master chosen, order status, delivery content, ratings and reviews, and support records.

Messages: chat messages exchanged with masters, AI conversations, and community posts or comments you create.

Photos and media: images you upload (for example, a profile photo) and images masters upload for their public profiles and galleries.

LIVE session data: booking details, participants, session time and duration, and technical connection data. We do not record the audio or video of LIVE sessions.

Payments and coins: coin balance and transaction ledger, purchase identifiers from Apple, Google, or RevenueCat, and subscription status. We do not receive or store your full card or bank details.

Usage and device data: features used, readings performed, app version, device type, operating system, and diagnostic logs.

Communications: messages you send to support, including your email address and the content of your request.

3. How We Use Your Information

To create and secure your account and provide the App's features.
To calculate charts, generate AI interpretations, and deliver readings.
To connect you with masters, process orders, and enable chat and LIVE sessions.
To manage coins, subscriptions, purchases, refunds, and master payouts.
To show ratings and reviews and to keep the marketplace trustworthy.
To send service messages, notifications, and support responses.
To detect abuse, fraud, and prohibited content, and to enforce our Terms.
To improve the App and comply with legal obligations.

We do NOT sell your personal information. We do not share your birth data with other users. Masters receive only the information needed to fulfil your order, and are required to keep it confidential.

4. AI Features

Some interpretations are generated by AI. To produce them, your question and relevant chart or birth details may be sent to our AI provider. AI output can be inaccurate or incomplete and is for entertainment and personal insight only. It is not medical, psychological, legal, or financial advice. Do not submit sensitive information you do not want processed to generate a reading.

5. Data Storage and Security

Data is stored on secure infrastructure provided by Supabase (Google Cloud, Singapore region) and Aliyun Object Storage Service for media. We use the following measures:

Encryption at rest: birth date, birth time, and birth location are encrypted using AES-256-GCM.
Encryption in transit: API communications use TLS/SSL.
Access control: users can access only their own data; staff access is restricted and audited.
Password hashing: passwords are hashed and never stored in plaintext.

No method of storage or transmission is 100% secure. We retain data while your account is active and as needed for support, dispute resolution, safety, and legal compliance. Reading history is retained for up to 30 days. When you delete your account, we delete or anonymise associated data within a reasonable period, except where retention is required by law or needed to resolve an ongoing dispute.

6. Data Sharing and Third Parties

We share information only as needed to operate the App:

Supabase — database, authentication, and storage infrastructure.
Aliyun — object storage for images and email delivery for verification and password reset messages.
Google Cloud — underlying cloud infrastructure.
Agora — real-time audio and video for LIVE sessions.
DeepSeek — AI processing for interpretations and chat features.
RevenueCat, Apple, and Google — purchase validation, subscriptions, and coin transactions.
Masters — the information necessary to provide the reading you ordered (such as your question, birth details, and order chat).
Authorities or other parties — when required by law, to protect safety, or to enforce our Terms.

These providers process data under their own terms and privacy policies. We require them to protect your information and use it only for the services they provide to us.

7. Your Rights

8. Children's Privacy

The App is not intended for individuals under 13 (or 16 in the EU/UK). Paid master services and LIVE sessions are intended for users aged 18 or older, or minors with verifiable parental consent. If we learn that a child has provided personal data in violation of this policy, we will delete it and terminate the account.

9. International Transfers

We and our providers may process data in Singapore and other countries where we operate. Where required, we use appropriate safeguards for cross-border transfers.
