Golden Stars does not collect, share, or transmit your data to the developer or any third party. The app has no analytics, advertising, accounts, or network access.
The app stores your visualization preferences locally on your device so they persist between sessions. This includes settings such as star geometry (dots and skips), colors, line thickness, fill mode, animation speed, Mandelbrot palette choice, Spirograph ring, wheel, pen, and style, and Julia palette and shape. These preferences are kept in a private file on your device only.
If you enable Android backup on your device, these preferences may also be included in your encrypted Google account backup or in device-to-device transfers. That backup is managed by Android/Google, not by this app or its developer. No preference data is sent to the developer.
