隐私政策
Lumi餐记（以下简称“本应用”）尊重并保护您的个人隐私。本政策用于说明本应用如何处理您在使用饮食记录、食物库、统计、饮水记录、照片、备份和导出功能时产生的信息。
本应用采用本地优先设计：饮食记录和相关设置默认仅保存在您的设备本地，不需要注册账号，也不会上传到我们的服务器。
一、我们处理的信息
1. 您主动记录的信息
您可以在本应用中主动输入或保存以下内容：
- 饮食记录，例如用餐类型、食物名称、分量、热量、蛋白质、碳水、脂肪和备注；
- 食物库内容，例如常用食物名称、分类、默认分量和营养参数；
- 饮水记录、每日目标、昵称、语言、主题、单位和提醒设置；
- 您主动选择或拍摄的餐食照片、头像。
2. 系统权限相关信息
只有在您主动使用相应功能时，本应用才会请求必要的系统权限：
- 相机权限：用于拍摄餐食照片；
- 照片库权限：用于选择餐食照片或头像；
- 通知权限：用于按照您开启的设置发送本地用餐或饮水提醒。
本应用不采集位置信息、通讯录、麦克风内容、广告标识符或设备唯一标识符，也不要求您注册账号。
二、我们如何使用信息
本应用仅在您的设备上将上述信息用于：
- 展示、编辑、排序和统计您的饮食及饮水记录；
- 提供食物库的收藏、编辑和快速添加功能；
- 根据您设置的目标生成趋势、营养占比、日历和简单反馈；
- 按照您主动开启的选项安排本地提醒；
- 执行您主动发起的数据备份、恢复、导出或分享操作。
本应用不使用您的饮食记录进行广告投放、个性化广告、用户画像或复杂的自动化分析。
三、信息的存储与传输
饮食记录、食物库、设置和照片路径默认存储在您的设备本地。本应用不会将这些内容上传至我们的服务器，也没有云端同步功能。
当您主动使用“导出”或系统分享功能时，您选择的数据会交由设备系统或您选择的分享目标处理。分享目标可能按照其自身的隐私政策处理相关内容；请在分享前确认目标和内容。
当您使用本应用的本地备份和恢复功能时，数据仍保存在设备本地，不会自动发送给我们。
四、信息的共享与披露
我们不会出售、出租或交换您的个人信息，也不会将本应用内的饮食记录提供给广告商、数据分析机构或其他第三方。
仅在以下情形下，相关信息可能离开本应用的本地环境：
- 您明确选择使用系统分享、导出或其他外部应用功能；
- 依据适用法律法规、司法程序或有权机关的合法要求必须提供；
- 为保护您、我们或公众的合法权益而确有必要。
五、信息安全
我们通过本地存储、权限控制和尽量减少数据收集的方式保护您的信息。由于设备、操作系统和电子存储介质都可能存在风险，我们无法保证信息安全绝对不受任何威胁。
请妥善保管您的设备及系统解锁凭证，并在分享或导出前确认文件内容和接收方。
六、您的权利与选择
您可以在本应用内：
- 查看、修改或删除饮食记录和食物库内容；
- 关闭相机、照片库或通知权限；
- 清空当日记录或清除全部本地数据；
- 创建本地备份、恢复本地备份或导出数据。
关闭相关权限可能导致对应功能无法使用，但不影响其他本地记录功能。由于数据默认只保存在您的设备上，卸载应用、清除应用数据或更换设备可能导致未备份的数据丢失。
七、第三方服务
本应用未接入广告、社交登录、云端同步或第三方行为分析服务。相机、照片库、通知和系统分享由设备操作系统提供；当您使用这些系统能力时，相关处理受设备系统及您选择的外部应用规则约束。
八、儿童隐私
本应用不以儿童为主要服务对象。我们不会通过网络故意收集儿童个人信息。如果您认为儿童在未获适当同意的情况下向我们提供了信息，请通过下方邮箱联系我们。
九、隐私政策的变更
我们可能根据功能变化、法律法规或隐私实践更新本政策。更新后的版本将在本页面发布，并更新“更新日期”和“生效日期”。如有重大变化，我们会在合理范围内通过应用内提示或其他适当方式告知您。

Privacy Policy
Lumi餐记 (“the App”) respects and protects your privacy. This policy explains how information is handled when you use meal logging, food library, statistics, water tracking, photo, backup, and export features.
The App is designed local-first: meal records and related settings are stored on your device by default. You do not need to create an account, and the App does not upload your records to our servers.
1. Information We Handle
Information you choose to provide
You may choose to enter or save:
- meal information, such as meal type, food name, portion, calories, protein, carbohydrates, fat, and notes;
- food library information, such as food names, categories, default portions, and nutrition values;
- water records, daily goals, nickname, language, theme, units, and reminder preferences;
- meal photos or an avatar that you choose or take.
System permissions
The App requests a permission only when you use the related feature:
- Camera: to take a meal photo;
- Photo library: to select a meal photo or avatar;
- Notifications: to deliver local meal or water reminders that you enable.
The App does not collect location data, contacts, microphone content, advertising identifiers, or unique device identifiers, and it does not require an account.
2. How Information Is Used
The App uses this information locally on your device to:
- display, edit, sort, and summarize your meal and water records;
- provide food saving, editing, and quick-add features;
- generate trends, nutrition balance, calendar views, and simple feedback based on your goals;
- schedule local reminders when you turn them on;
- perform backup, restore, export, or sharing actions that you initiate.
The App does not use your meal records for advertising, personalized ads, user profiling, or complex automated analysis.
3. Storage and Transfer
Meal records, food library entries, settings, and photo paths are stored locally on your device by default. The App does not upload them to our servers and does not provide cloud synchronization.
When you explicitly use export or the system share feature, the data you select is passed to the operating system or the sharing destination you choose. That destination may handle the data under its own privacy policy. Please review the destination and content before sharing.
When you use local backup and restore, the backup remains on your device and is not automatically sent to us.
4. Sharing and Disclosure
We do not sell, rent, or exchange your personal information, and we do not provide meal records to advertisers, analytics companies, or other third parties.
Information may leave the App’s local environment only when:
- you explicitly choose system sharing, export, or another external-app feature;
- disclosure is required by applicable law, legal process, or a lawful request from an authority;
- disclosure is reasonably necessary to protect your rights, our rights, or public safety.
5. Information Security
We protect information through local storage, permission controls, and data minimization. However, no device, operating system, or electronic storage method can be guaranteed to be completely secure.
Please protect your device and system credentials, and confirm the file contents and recipient before exporting or sharing.
6. Your Choices and Rights
Within the App, you can:
- view, edit, or delete meal and food library records;
- disable camera, photo library, or notification permissions;
- clear today’s records or delete all local data;
- create a local backup, restore a local backup, or export your data.
Disabling a permission may make the related feature unavailable but will not affect other local record features. Because data is stored locally by default, uninstalling the App, clearing its data, or changing devices may delete data that has not been backed up.
7. Third-Party Services
The App does not integrate advertising, social login, cloud synchronization, or third-party behavioral analytics. Camera, photo library, notifications, and system sharing are provided by the device operating system; use of those capabilities is subject to the operating system and any external app you select.
8. Children’s Privacy
The App is not directed primarily to children. We do not knowingly collect children’s personal information through a network service. If you believe a child has provided information without appropriate consent, please contact us using the email below.
9. Changes to This Policy
We may update this policy when features, laws, or privacy practices change. The updated version will be posted on this page with revised update and effective dates. For material changes, we will provide notice through the App or another appropriate method where reasonably possible.
