Records on your devices

Water amounts and times, daily goals, cup sizes, reminders, preferences, and collection progress are stored on your device. Your iPhone and paired Apple Watch exchange records and settings; offline Watch entries remain queued until they can sync. Widgets share a daily summary and hide it when App Lock is enabled.

Optional permissions

• Notifications: your device schedules local drinking reminders. You can turn them off in system settings.
• Apple Health: if you enable sync and grant permission, the app writes saved water amounts and times, including existing history, to Apple Health. Edits and deletions are also synced. It does not read other Health data. Turning sync off keeps records already written to Health; you can manage those records and permissions in Apple Health.
• App Lock: authentication uses system Face ID, Touch ID, or your device passcode. The app does not receive your biometric data or passcode.

Purchases and backups

Apple handles purchases and payments. The app uses purchase status to unlock Pro features and does not receive your payment card details.

You choose where to save exported backup files containing records and settings. Device backups may also include app data according to your Apple backup settings. The developer cannot access your personal backups.

Managing and deleting data

You can delete entries or use Clear Data in the app to remove local drinking records, collection progress, and preferences. Clear Data also requests deletion of records this app wrote to Apple Health; if deletion cannot complete, manage them in Apple Health. Exported files and system backups are managed separately and are not deleted by Clear Data.

设备上的记录

喝水量、记录时间、每日目标、杯量、提醒、偏好及收藏进度保存在本机。iPhone 与配对的 Apple Watch 会同步记录和设置，手表离线记录保留至可同步时传输。小组件共享今日摘要，开启应用锁后会隐藏内容。

可选权限

• 通知：设备安排本地喝水提醒，你可以在系统设置中关闭通知。
• 苹果健康：开启同步并授权后，应用会将已保存的喝水量与记录时间写入苹果健康，包含已有历史；编辑和删除也会同步。不读取其他健康数据。关闭同步会保留已写入健康的记录，你可以在苹果健康中管理这些记录和权限。
• 应用锁：使用系统面容 ID、触控 ID 或设备密码验证，应用无法获取你的生物识别数据或设备密码。

购买与备份

购买和付款由 Apple 处理。应用根据购买状态开放 Pro 功能，不会获取你的银行卡信息。

导出的备份文件包含记录和设置，由你选择保存位置。系统也可能根据你的 Apple 备份设置备份应用数据。开发者无法访问你的个人备份。

管理与删除数据

你可以删除单条记录，或在应用内使用“清除数据”移除本机喝水记录、收藏进度及偏好。清除时也会请求删除本应用写入苹果健康的记录；如果未能完成删除，请在苹果健康中管理。已导出的文件和系统备份需单独管理，不会随“清除数据”一同删除。
