支持与帮助

小岁记支持 iPhone（iOS 17.0 及以上）、iPad 和 Apple Watch。数据可通过 iCloud 在多设备间同步。

您的所有数据默认存储在设备本地，不会上传至任何第三方服务器。如果您开启了 iCloud 同步，数据将通过 Apple 的加密通道在您自己的设备间同步，我们无法访问。

可以。小岁记支持添加多个宝宝的档案，方便有多个孩子的家庭使用。您可以在宝宝列表中轻松切换。

进入 App 设置页面，开启"生物识别锁定"选项即可。开启后每次打开 App 需要验证身份。

小岁记使用世界卫生组织（WHO）发布的儿童生长标准数据，可以直观对照宝宝的身高、体重、头围发育百分位。

在 App 设置中，您可以导出所有记录为 CSV 或 PDF 格式。如需删除数据，可在设置中选择清除所有数据，或直接卸载 App。

如果您已开启 iCloud 同步，在新设备上登录相同的 Apple ID 并安装小岁记后，数据会自动同步过来。您也可以通过 iPhone 的整机备份恢复功能迁移数据。

小岁记完全免费，无广告，无内购。所有功能均可免费使用。

XiaoSuiJi supports iPhone (iOS 17.0+), iPad, and Apple Watch. Data can be synced across devices via iCloud.

All your data is stored locally on your device by default and is never uploaded to any third-party server. If you enable iCloud sync, data is synced between your own devices through Apple's encrypted channels — we cannot access it.

Yes! XiaoSuiJi supports multiple baby profiles, making it easy for families with more than one child. You can easily switch between profiles.

Go to Settings in the app and enable the "Biometric Lock" option. Once enabled, you'll need to verify your identity each time you open the app.

XiaoSuiJi uses the World Health Organization (WHO) child growth standards to help you compare your baby's height, weight, and head circumference percentiles.

In Settings, you can export all records as CSV or PDF. To delete data, use the "Clear All Data" option in Settings, or simply uninstall the app.

If you've enabled iCloud sync, simply sign in with the same Apple ID on your new device and install XiaoSuiJi — your data will sync automatically. You can also use iPhone's full backup restore.

XiaoSuiJi is completely free with no ads and no in-app purchases. All features are available for free.
