1. 处理的信息

为了整理家庭物品，App 可在设备本地处理你主动录入的物品名称、分类、位置、品牌、型号、序列号、购买与保修日期，以及照片、票据和附件。OCR 识别与整理也在设备本地完成。

2. 设备权限

• 仅当你选择拍摄时请求相机权限。
• 使用系统照片选择器时，只取得你明确选择的项目。
• 仅当你启用保修提醒时请求通知权限。
• 拒绝权限后仍可手动记录；你可以随时在系统“设置”中更改权限。

3. 不收集与不共享

开发者不会上传你的物品记录、照片、票据、OCR 内容、通知设置或使用行为；不会出售数据，也不会用于广告画像。

4. 本地存储、导出与删除

数据保存在 App 的本地容器中。你可以删除单个记录、导出完整备份或可阅读的 PDF；恢复备份时，App 会验证文件完整性。

删除 App 会移除其本地数据。更换设备或删除 App 前，请先将备份导出并妥善保存。备份由你控制；通过其他 App 或服务分享、保存后，适用相应服务的隐私政策。

5. 儿童隐私

App 无账号，不主动收集年龄或身份。请勿在物品记录中输入不必要的敏感个人信息。

6. 未来变更

如果未来加入云同步、分析、崩溃报告或第三方服务，我们会在启用前更新本政策、App 内说明、App Store 隐私信息及相关声明。

1. Information processed

To organize household items, the app can process information you enter—such as item name, category, location, brand, model, serial number, purchase and warranty dates—along with photos, receipts, and attachments. OCR and organization happen on device.

2. Device permissions

• Camera access is requested only when you choose to take a photo.
• The system photo picker gives the app access only to items you explicitly select.
• Notification permission is requested only when you enable warranty reminders.
• You can still record items manually after denying access and change permissions later in Settings.

3. No collection or sharing

The developer does not upload your item records, photos, receipts, OCR content, notification settings, or usage behavior. Data is not sold or used for advertising profiles.

4. Local storage, export, and deletion

Data is stored in the app’s local container. You can delete individual records and export either a complete backup or a readable PDF. The app checks backup integrity before restoring.

Deleting the app removes its local data. Before changing devices or deleting the app, export and safely store a backup. You control where backups go; once shared or saved through another app or service, that provider’s privacy policy applies.

5. Children

The app has no account and does not actively collect age or identity. Do not enter unnecessary sensitive personal information in item records.

6. Future changes

If cloud sync, analytics, crash reporting, or third-party services are added later, we will update this policy, the in-app explanation, App Store privacy information, and applicable declarations before enabling them.
