Starchart is practice software for astrologers. Practitioners use it to store client birth data, write reports, publish share links, and optionally send writing drafts to their own Ghost sites. Clients do not create Starchart accounts.
Roles
The practitioner is the data controller for their client records. Starchart acts as a processor for the information the practitioner enters and publishes through the app.
Data we process
- Practitioner account and profile details, including name, email, practice name, website, and settings.
- Client records entered by practitioners: name, birth date and time, birth timezone, birth city/place, latitude, and longitude.
- Astrological calculation outputs derived from birth data, including chart data and astrocartography line data.
- Report, writing, and Library content created by the practitioner, including private report context notes.
- Published share-link settings, including optional report password hashes and revocation state.
- Optional Ghost publishing configuration, stored encrypted, for practitioner-initiated draft sync.
- Operational records such as invite tokens, activity logs, imports, exports, and waitlist submissions.
Where data is stored
Application data is stored in Neon Postgres. File uploads, rendered chart/map images, and generated assets may be stored in Cloudflare R2. The ephemeris service runs on DigitalOcean and receives birth data only as needed to calculate charts, maps, and related astrological outputs.
TODO before paid launch: confirm and publish the active Neon, Cloudflare R2, Vercel, and DigitalOcean regions and data processing agreements.
Published share links
Published report URLs are public unless the practitioner adds a password. A share URL may include the client name, birth details, chart/map images, and report prose chosen by the practitioner. Private report context notes are not published. Practitioners can revoke a share URL by unpublishing the report.
Retention, export, and deletion
Practitioners can export their data and delete client records from the app. Account deletion removes the practitioner's Starchart data, including people, reports, writings, Library entries, and profile data.
TODO before paid launch: define backup retention windows, deleted-file retention for R2 assets, and any support process for practitioner or client data requests.
Third-party services
Starchart uses infrastructure and service providers to run the app, including Vercel, Neon, Cloudflare R2, DigitalOcean, MapTiler, and optional Ghost integrations configured by practitioners.
Contact
Privacy requests should be sent to Zen Design Labs. TODO before paid launch: publish the official privacy contact email here.
