Privacy Policy
XiaoriGuang is designed to keep data on your device and does not require an account. The app connects to Firebase only when you choose Family Sharing, allowing authorized devices in the same family to sync.
Data stored on your device
When Family Sharing is not used, baby names, birth dates, care records, notes, reminder settings, and display preferences stay on the device. The app and its widget use an App Group to read a minimized local care summary.
Optional Family Sharing
Family Sharing uses Firebase Anonymous Authentication to create a random device identifier. No email address, phone number, or password is required. After creating or joining a family, baby profiles, care records, and family member nicknames are encrypted in transit and stored in Google Firebase for authorized devices in that family.
This data is used only for family synchronization, not advertising, analytics, or marketing. Firebase may process IP address, device, and error information as needed to operate its services. A member who leaves or is removed stops syncing. When the family owner dissolves a family, its cloud members, baby profiles, and care records are deleted.
Export, restore, and deletion
You can create CSV or JSON files and choose where to save or share them. Before importing JSON, the app shows a summary and asks you to confirm that current device data will be replaced. Leaving or removing a family uses a soft-delete process; dissolving a family permanently deletes that family's cloud data.
Notifications and optional support
Reminders are scheduled locally only after the user grants permission. If you make a support purchase, Apple processes the payment. XiaoriGuang does not receive credit card or Apple Account payment details. Support purchases never unlock, restrict, or change any feature.
What we do not do
XiaoriGuang does not require a real name, email address, phone number, or password. It contains no advertising or cross-app analytics tracking and does not sell personal or care data.
