隐私政策

一、适用范围与运营者

本政策适用于“啵啵几何工坊”iOS 应用（以下简称“本应用”）。本应用运营者为 App Store 产品页面所示的开发者或销售商（以下简称“我们”）。

二、我们处理的信息

计算输入、结果与历史：你输入的边长、角度及场景尺寸仅在设备上用于计算和绘图。最多 20 条历史记录保存在本应用的本地沙盒中，不会上传至开发者服务器。

应用偏好：语言、字体大小、场景开关和工具顺序等设置保存在设备上。

订阅权益：本应用使用 Apple StoreKit 获取产品信息并核验订阅权益。我们不接触付款卡号、Apple 账户密码或完整付款资料，也不在开发者服务器保存交易记录。

三、我们不收集的信息

当前版本不要求注册账户，不包含开发者运营的后台服务、广告、用户追踪、行为埋点或第三方分析 SDK，也不请求相机、照片、麦克风、通讯录或位置权限。

我们不出售个人信息，也不将本应用内的数据用于定向广告。

四、复制、分享与第三方服务

只有在你主动点击“复制结果”时，相关内容才会写入系统剪贴板。只有在你主动使用分享功能并选择接收应用后，相关计算内容才会交给该应用；接收方的处理方式受其自身隐私政策约束。

购买、续订、退款、家庭共享、订阅恢复，以及 Apple 提供的可选诊断或 App 分析由 Apple 独立处理。请参阅 Apple 隐私政策。

五、保存、删除与用户选择

计算历史会保留在设备上，直至你逐条删除、清空历史或卸载本应用。偏好设置会保留至你修改、恢复默认设置或卸载本应用。

你可以随时不保存或清空历史、更改偏好、停止使用或卸载本应用。由于我们不在开发者服务器保存账户或计算数据，通常没有可供访问、更正或删除的服务器端个人数据。

六、安全、儿童隐私与政策更新

本地信息受 iOS 应用沙盒及设备安全机制保护。本应用是通用计算工具，不以儿童为主要对象，也不会主动收集儿童个人信息。

我们不运营用于接收本应用数据的服务器，因此不会主动将计算数据传输至境外。如功能或数据处理方式发生变化，我们会更新本政策及生效日期。

1. Scope and Operator

This Privacy Policy applies to the Bobo Geometry Workshop iOS app (the “App”). The operator is the developer or seller identified on the App Store product page (“we,” “us,” or “our”).

2. Information We Process

Calculation inputs, results, and history: Measurements and angles are processed on your device for calculations and drawings. Up to 20 history records are stored in the App’s local sandbox and are not uploaded to a developer server.

App preferences: Language, text size, tool visibility, and tool order are stored on your device.

Subscription entitlement: The App uses Apple StoreKit to load product information and verify active subscription entitlement. We do not receive payment card numbers, Apple Account passwords, or complete payment details, and we do not store transaction records on a developer server.

3. Information We Do Not Collect

The current version requires no account and includes no developer-operated backend, advertising, user tracking, behavioral analytics, or third-party analytics SDKs. It does not request access to the camera, photos, microphone, contacts, or location.

We do not sell personal information or use App data for targeted advertising.

4. Copying, Sharing, and Third Parties

Calculation content is written to the system clipboard only when you tap Copy Results. It is provided to another app only after you use the share feature and select a destination. The destination’s own privacy policy governs its handling of that information.

Purchases, renewals, refunds, Family Sharing, restoration, and optional diagnostics or App Analytics provided by Apple are processed independently by Apple. See Apple’s Privacy Policy.

5. Retention, Deletion, and Your Choices

Calculation history remains on your device until you delete records, clear history, or uninstall the App. Preferences remain until changed, reset, or the App is uninstalled.

You may choose not to save history, clear local history, change preferences, stop using the App, or uninstall it at any time. Because we store no account or calculation data on a developer server, we generally hold no server-side personal data for you to access, correct, or delete.

6. Security, Children, and Policy Updates

Local information is protected by the iOS app sandbox and device security features. The App is a general-purpose calculator and is not directed primarily to children. We do not knowingly collect children’s personal information.

We operate no server that receives App data and therefore do not actively transfer calculation data across borders. If the App’s features or data practices change, we will update this Policy and its effective date.
