Celestiary Privacy Policy
Updated September 29, 2026
Readings on your device
The app calculates readings in your browser using birth details, profile information and answers you enter. Browser storage holds profiles and results. Searching for a birthplace sends the city or ZIP search to Open-Meteo or Zippopotam. Avoid entering another person’s details without their permission.
Optional accounts and cloud copies
Google sign-in provides account identity information. Signed-in profiles, readings and purchased guides may be saved in Google Firebase for access across devices. Clearing browser storage does not delete those cloud copies or cancel a subscription.
AI-written guides
When you request a written guide, relevant birth details and computed results are sent through our server and Vercel AI Gateway to an AI provider. The configured providers include Anthropic and Google; requests may use a fallback provider if the primary service is unavailable. AI processing is subject to the providers’ applicable service terms. Do not submit information you do not want processed this way.
Weekly readings, email and push
If you enroll in Weekly, we store your selected profile, account email, timezone, processing consent, subscription information and generated issues in Firebase. Scheduled generation uses that saved reading, and Resend delivers emails. If you enable push, we store a subscription for your browser and send notifications through push services. A sample issue also involves server processing and storage.
Payments and hosting
Stripe processes payments and returns purchase and subscription identifiers and status. We do not receive your full card number. Vercel hosts the service and provides page-view analytics. Operational services may process technical information such as IP addresses. We do not sell your personal data or use advertising trackers. Do Not Track does not change these practices.
Access, cancellation and deletion
Clear site data in your browser to remove local copies on that device. Use the Weekly page’s Manage or cancel control for recurring billing. To request cloud account, profile, guide, weekly issue or push-subscription deletion, email us from your account address. Tell us whether you also want any subscription canceled; deleting a local copy or signing out does not stop billing. We may retain records necessary for payments, disputes or legal obligations and will explain applicable exceptions.
Retention and contact
We keep information needed to deliver the service, handle support, prevent fraud and meet legal obligations. You can request deletion. Billing, dispute and legally required records may need to be retained; we will explain any applicable exception. Copies held by payment providers are subject to their own obligations. For privacy, access, correction or deletion requests, email samuel.taylor19@gmail.com. Please identify the product and your purchase or account email; do not send passwords or full payment-card details. We may need to verify your identity before acting.
Children and changes
Purchases and account setup are intended for adults. Contact us if a child has submitted personal information without appropriate permission. We will date material changes to this policy here.
