Privacy Policy
Last updated: August 24, 2026
CatchSay ("we", "us") provides an AI-powered saju (Four Pillars) and fortune-telling service. This policy explains what data we collect, how we use it, and your choices. It is currently provided in English; localized versions may follow.
1. Information we collect
- Birth information — birth date, time, and gender, if you choose to provide them, and whether the date is lunar. Used only to calculate your saju chart and generate a personal reading. You can use the app without entering this.
- Account information — email address and authentication details when you sign up.
- Conversations & usage — messages you exchange with our AI characters and basic usage metrics (e.g. tokens consumed) to operate and improve the service.
- Payment information — when you purchase a plan or tokens, payments are processed by Stripe. We do not store your full card details; Stripe does.
- Physical-order information — when you order a physical talisman, we collect the recipient's name, email address, phone number, delivery address, order amount, and payment status. Stripe collects the address and payment details through its secure checkout.
- Analytics — privacy-friendly, cookie-less usage analytics (self-hosted Umami) such as page views and funnel events. We do not sell this data.
2. How we use your information
- To compute your saju chart and generate personalized readings and voice content.
- To create and secure your account, and to provide customer support.
- To process payments, manage subscriptions, and prevent abuse.
- To confirm, prepare, and deliver physical talisman orders, and to provide order support.
- To understand and improve how the service is used.
3. AI processing
To generate saju readings and chat responses, the following data is sent to a third-party LLM provider (DeepSeek) as well as our self-hosted AI model: your birth date, time, and gender if provided, the derived saju chart (heavenly stems, earthly branches, five elements, etc.) calculated from that information, and your chat messages. This data is used solely for fortune-telling and conversational responses — it is not used for advertising or marketing purposes. Birth date/time and gender that you have not entered are never sent.
4. Third parties
We rely on service providers including Stripe (payments and secure checkout), AI model providers — specifically DeepSeek (third-party LLM API) and our own self-hosted AI models (reading and chat generation), Resend (transactional email), and Cloudflare (infrastructure and email routing). Each processes data only to provide their service to us. We do not sell personal data to any third party.
5. Data retention
We retain account and reading data for as long as your account is active. Physical-order and shipping information is retained only for as long as needed to fulfill the order, provide support, and meet applicable record-keeping obligations. You may request deletion of your account and associated data at any time (see Contact), subject to those obligations.
6. Your rights
You may access, correct, or delete your personal data, and clear your stored birth information from your account settings. To exercise these rights, contact us below.
7. Children
The service is not directed to children under 13 (or the minimum age in your jurisdiction).
8. Changes
We may update this policy. Material changes will be reflected by the "Last updated" date above.
