What we use to cast the chart.
Updated
Birth details and readings
Birth date, time when known, and selected birthplace are used to calculate a chart. Your chosen name and reading focus help present it. Location search sends the place query to a mapping service to find matching coordinates and a time zone.
Generating a reading sends chart context to OpenAI. Chat answers can also use the question, saved chart, and conversation context. Do not include information in a question that you do not want processed for that answer.
Guests, accounts, and stored history
You can try the chart and first reading before creating an account. That does not create a saved account chart. Requests still pass through the services needed to calculate, generate, deliver, and monitor the experience.
When you save a chart, Supabase stores account information and private chart data. Saved readings and membership question history can be stored with the account. Authentication uses cookies; parts of the chart journey also use browser session storage.
Service providers
Supabase supports authentication and storage. OpenAI generates readings and answers. Langfuse supports AI tracing, which can include generation inputs and outputs. PostHog supports usage analytics and error monitoring. Resend delivers account and requested emails. Stripe processes membership payments and billing. Hosting services process requests and operational logs.
These services process data for their respective functions. This page does not promise that a guest request leaves no operational records or that monitoring is anonymous.
Chart links and email choices
If you request an emailed chart link, the link carries encoded birth details so the chart can be reopened. Encoding does not make the link secret or encrypted. Anyone you share it with may be able to read those details. Treat it as private.
Account and requested service emails support sign-in and delivery. Marketing email is optional. Signed-in users can change that choice in email preferences.
Storage, correction, and deletion requests
Saved chart and reading records are stored for account access and history. Cancelling membership changes paid access; it does not itself delete an account, its saved history, or billing records. This site does not offer an automatic account-deletion control.
For access, correction, deletion, or retention questions, email the.astral.meridian@gmail.com from your account email. We may need to verify the account before acting on a request. Do not send your password or payment-card details.
