Saju Studio does not collect personal information. The birth date, birth time, time zone, and sex you enter for your chart are processed entirely on your device. They are never transmitted to or stored on our servers.
If — and only if — you purchase Pro, the payment information Google Play issues is sent to and stored on our server so we can verify the purchase. The app transmits a purchase token (a payment receipt identifier), an order number (GPA. format), and a product identifier. Alongside these, our server records the purchase state (purchased, refunded, pending, and so on), whether it was verified, the payment amount, and the created/updated timestamps; if Google also supplies an account-linkage identifier, that identifier may be stored as well. This payment information contains no personally identifying information such as your name, email, or date of birth.
The app also records, on our server, whether certain features were used — such as generating a chart, viewing a day-pillar (ilju) card, or saving a result card — keyed to an anonymous install identifier randomly generated on your device at install time (not an advertising ID or device identifier, and not linked to you personally). Your birth date, birth time, sex, and other chart inputs and calculation results are never included in this record and remain processed entirely on your device. The same identifier is also used to determine which marketing channel (an ad, a social post, etc.) led to the install.
This payment information is used solely to verify payment validity, tally revenue, and apply refunds. The anonymous usage statistics above are used solely to understand feature usage and measure marketing channel performance.
This payment information is retained for payment record-keeping. Where no statutory retention obligation applies, we delete it without undue delay upon your request. The anonymous usage statistics are retained only for non-identifying aggregate purposes.
We do not share collected information with third parties. Payment processing is performed by the Google Play billing system, to which Google's own privacy policy applies separately.
This app serves no advertising and collects no advertising identifiers (e.g. Advertising ID). It does collect the minimal anonymous, install-scoped feature-usage and marketing-attribution data described in Section 1; this identifier does not identify you personally and is not shared with any third-party ad network.
Because this app collects no personal information, it collects no personal information from children either. The anonymous usage statistics above likewise do not identify age or identity.
