Privacy Policy
Last updated: 14 June 2026
Sajura ("we", "the app") is a Korean astrology (saju) app for entertainment. This policy explains what we collect and how it is used. By using the app you agree to this policy.
What we collect
To calculate your saju chart and generate readings, you provide your first name, date of birth, time of birth (optional), and birthplace (optional). If you choose to create an account, we also collect your email address (and, with Google sign-in, your name as provided by Google). We do not ask for a phone number or any government identifier.
Where your data is stored
If you use Sajura without an account, your birth details and readings stay on your own device (your browser's storage); clearing your browser data removes them. If you sign in, your profile is also stored on our servers (via our hosting and database provider, Supabase) so it can sync across your devices. You can delete this any time — see "Your choices & rights".
AI-generated readings
When you request a personalized reading, the data derived from your birth details (your saju chart) is sent to our AI provider, Anthropic, which processes it to generate the reading text and returns it to you. We send the chart and your first name — not your raw birth certificate. Anthropic processes the request under its own terms and does not train its models on it.
Analytics
We collect anonymous, aggregated usage events (e.g. which screens are viewed, whether an invite was shared) to understand and improve the app. Your birth details are never sent to analytics.
Payments
If you subscribe to Premium, payments are processed by Stripe. We never receive or store your full card number — Stripe handles all card data. We store only your subscription status, plan, and renewal date, linked to your account, to unlock Premium features.
Age requirement
Sajura is for users aged 18 and older. We do not knowingly collect information from anyone under 18. If you believe a minor has used the app, contact us and we will help remove the data.
Your choices & rights
You're in control: without an account, clear your data any time from your browser settings. With an account, you can sign out, or delete your account and all stored data any time from Account → Delete my account. If you are in the EU/EEA or UK, you have rights to access, correct, and erase your personal data under the GDPR; contact us to exercise them.

Changes
We may update this policy; the "last updated" date will change accordingly.
This document is a starting template for a prototype, not legal advice. Have it reviewed by a qualified lawyer before any public launch, especially for GDPR (EU/France) and COPPA (US) compliance.
