SiblingCare ("the app") is a free family care board developed by Tong Zhang.
None. The app has no ads, no analytics, no tracking, no account and no servers. Care circle names, tasks, medication notes, cost records and emergency card details you enter, and any photos of documents you take, are stored and processed only on your device and are never sent to us or any third party. Document photos are saved on your device; the app has no AI or automatic recognition and no image leaves your phone. Optional reminders are local iOS notifications on this device only; the app never sends messages to other people. Text you choose to share (for example the emergency card) is passed to the iOS share sheet and sent only where you choose. Deleting the app, or "清除本机所有数据" in the app, removes all of its data.
Health-related information you enter stays on your device. SiblingCare does not provide medical advice; always follow your doctor and pharmacist.
The app does not collect data from anyone, including children.
Changes will be posted on this page.
