Privacy Policy
The information we collect, how we use it, and when it is sent to external services.
- Data when you are not logged in is mainly saved within the device (browser storage).
- When signed in, profiles, settings and chat history are saved to and synced with your account.
- When using the AI function, the input text and reference data are sent to an external AI API (Google Gemini API).
- Payments are made with Stripe, donations are made with PayPal, and no credit card information is saved in the app.
- We may use access analysis (Google Analytics).
1. Information we collect
- Profile details (date of birth and optional birth time, birthplace, name and similar details)
- Chat messages (the text you enter in AI chat)
- Account information (user ID, email address, and information required for authentication and synchronization)
- Device information (identifiers saved by your browser, local storage and similar information)
- Usage analytics (browsing information collected through cookies and similar technologies to understand usage)
2. Storage location (not logged in/logged in)
- Not logged in: It is mainly saved in the browser storage (localStorage, etc.) within the device. Data may be lost if you delete your browser data.
- Log in: Profiles, settings and chat history are saved to and synced with your account, so you can use the same data on other devices.
- The retry cache expires after one hour and is deleted on the next AI request. Deleting an account also deletes that account’s cached AI responses.
3. Sending to external services
When you use AI readings or AI chat, the text you enter and the reference data (profile names and calculated results)needed for the reading, along with conversation context when needed, are sent to an external AI API (Google Gemini API, including requests through a proxy). If you include personal details such as your real name or address in a message, those details may also be sent.
“Do not send to external AI” stops transmission for AI features. This setting does not stop account synchronization while signed in or analytics.
- Stripe Checkout: Used to pay for point purchases (card information etc. is processed by Stripe and not saved in the app).
- PayPal: Used for donations (development support) (separate from point granting).
- Google Analytics（gtag.js）: May be used to understand and improve usage status.
4. Purpose of use
- Horoscope calculation and display of results
- Providing AI functions (fortune telling/chat)
- Account functions (login, data storage/synchronization, password reset)
- Management of point purchase/transaction history
- Analysis and improvement of usage status, prevention of unauthorized use
5. Cookies etc.
This service may use cookies, browser storage, etc. to provide functionality (login status, UI settings retention, etc.) and access analysis.
