久用 (LongUse) - 隐私政策 Privacy Policy

Records and iCloud

LongUse records item names, purchase prices, dates, categories and notes that you enter. These records are stored on your device. If you enable iCloud for LongUse, records sync through Apple CloudKit to your private iCloud database. You can use the core app locally without creating an app account. The developer does not operate a server receiving your item records.

Optional cloud analysis

Offline statistics calculate costs on your device without a network request or AI model. You may optionally configure a cloud service (DeepSeek, OpenAI, Anthropic, or a compatible HTTPS endpoint) using your own API key. Before each analysis request, the app identifies the receiving endpoint and asks for confirmation. It sends only item counts, average days owned and aggregate daily costs. Item names, notes and individual purchase details are not included. Requests go directly from your device to the selected service.

The selected provider processes requests under its own privacy policy and terms, and may charge fees. Review these before confirming. The provider receives network information, such as your IP address, as part of the connection. API keys are saved in this device's Keychain and are used to authenticate requests to the service you select. You can remove a key by clearing its field in Analysis settings. Generated analysis is displayed during the current session and is not stored by LongUse.

Widgets and notifications

Widgets read an on-device snapshot shared with the app. They do not upload data. Notifications are optional and use Apple's notification permission. Cost goals are checked when the app is opened or relevant records change.

No advertising or behavioral tracking

LongUse has no advertising SDKs, behavioral trackers or third-party analytics SDKs. The developer does not sell your data.

Control and deletion

You can edit or delete individual items, or delete all item records in Settings. If iCloud is enabled, deletion syncs to your other devices and cannot be undone in LongUse. Removing the app clears its local app container; it does not automatically delete records in iCloud or keys in the system Keychain. Custom categories and display preferences are stored locally.

Contact and updates

For support or privacy questions, contact us through GitHub Issues. Do not post purchase records, API keys or other private details in a public issue. Policy changes will be published here with an updated date.

物品记录与 iCloud

久用将您输入的物品名称、购买价格、日期、分类和备注保存在设备上。若为久用启用 iCloud，记录会通过 Apple CloudKit 同步至您的私人 iCloud 数据库。核心功能无需创建 App 账号即可在本机使用。开发者不运营接收物品记录的服务器。

可选云端分析

离线统计只在设备上计算，不联网，也不使用 AI 模型。您可以自行配置 DeepSeek、OpenAI、Anthropic 或兼容的 HTTPS 服务，并填写自己的 API 密钥。每次请求前，App 会展示接收服务地址并请求确认，仅发送物品数量、平均使用天数及汇总日均成本，不发送名称、备注或逐项购买明细。请求直接由设备发送至所选服务。

服务提供商按其隐私政策和条款处理数据，可能收取费用；请在确认前查看。网络连接会向服务提供商暴露 IP 地址等连接信息。API 密钥保存在此设备的钥匙串中，用于验证对所选服务的请求；可在分析设置中清空密钥字段进行移除。分析结果仅在当前会话中显示，久用不持久保存该结果。

小组件与通知

小组件读取与主 App 共享的本机数据快照，不上传数据。通知为可选功能，需获得系统通知权限。日均目标在打开 App 或相关记录变更时检查。

无广告和行为追踪

久用不包含广告 SDK、行为追踪器或第三方分析 SDK。开发者不出售您的数据。

管理与删除

您可以编辑、删除单项物品，或在设置中删除全部物品记录。若开启 iCloud，删除操作也会同步到其他设备，在久用中无法撤销。卸载 App 会移除本机 App 容器，但不会自动删除 iCloud 记录或系统钥匙串中的密钥。自定义分类和显示偏好保存在本机。

联系与更新

如需支持或有隐私问题，请通过 GitHub Issues 联系我们。请勿在公开问题中填写购买记录、API 密钥或其他私人信息。政策变更将在此页面发布并更新日期。
