Stellara treats your data with the same precision we apply to celestial calculations. This policy explains what we collect, why, and how you stay in control.
The birth data you provide (name, date, time and place of birth), the coordinates obtained through geocoding, and your gender and field of work if you specify them. When you link Telegram, we store your Telegram ID to deliver briefs. If you reply to briefs, we store the text of your replies; taps on the buttons under briefs are stored as the state of the topic, confirmed or dropped. When you pay with Telegram Stars, we store the payment ID and amount. We do not collect visit analytics, tracking cookies or device fingerprints.
Your data is used to calculate your natal chart, generate texts and deliver the briefs you set up. We do not sell your data or disclose it for advertising. To run the service, some data is processed by providers: OpenCage, your birthplace, to find coordinates; Anthropic, the data needed to generate texts (see below); Telegram, brief delivery and payments; Railway and Vercel, hosting.
The chart portrait, planet sections, briefs and the Sunday note are generated through the Anthropic Claude API. The request includes your name, date, time and place of birth, the calculated chart positions, your gender and field of work if you specified them, and the text of your replies to briefs, so that the next brief can continue the topic and the Sunday note can draw on them. Button taps are not sent as text; only whether a topic is confirmed is taken into account. Your Telegram ID is not included. Anthropic does not use data received through the API to train its models.
Data is stored in a PostgreSQL database hosted on Railway infrastructure within the EU. Connections are encrypted in transit. Access is restricted to the application service only.
You can delete your account at any time on the chart page. Your profile, natal chart, briefs, replies, topics and subscription are deleted immediately and irreversibly. To cancel an auto-renewal or refund Stars, a separate record is kept: Telegram ID, payment ID and amount. This record remains after the operation is complete. The history of Stars transactions is also kept on Telegram's side.
