记录一杯

首页点击“提交饮水证据”，拍照或选择照片，填写本次实际喝掉的水量，再保存。一天可记录多次。

导出完整备份

首页右上角“数据与隐私”→“导出完整备份（含照片）”，在系统菜单选择保存到“文件”。完成保存才形成外部备份。

导入恢复

在同一页面选择“从文件导入完整备份”，选择 .dashui 文件。相同记录跳过，冲突时停止。当前索引损坏时也可导入完整备份恢复。

恢复上一份本地备份

这会回退前一次记录索引，可能撤回最近一次新增或删除。照片缺失不能只靠索引恢复，需要完整备份。

照片看不到怎么办

保留 App，先尝试导入包含照片的完整备份。不要先卸载，否则本机记录也会移除。

使用边界

免费使用，支持简体中文和英文。水量由你填写，仅用于个人记录，不提供饮水量或健康建议。

Log a drink

On the home screen, submit a photo, take or select an image, enter the amount you actually drank, and save. You can log multiple drinks each day.

Export a complete backup

Open Data & Privacy using the information button on the home screen, then export a complete backup including photos. Choose Save to Files in the system share sheet and finish saving. Opening the share sheet alone does not save a backup.

Import and restore

Use the import option on the same screen and select a .dashui file. Identical entries are skipped. Conflicts stop the import. A complete backup can also restore a damaged record index.

Restore the previous local backup

This rolls back the previous record index and may undo your latest addition or deletion. Missing photo files require a complete backup; restoring only the index cannot repair them.

A photo is missing

Keep the app installed and try importing a complete backup that includes the photo. Do not uninstall first, as this removes local records too.
