Super Calculator Privacy Policy

Last updated: September 3, 2026

This policy applies to Super Calculator (超级计算器), a local-first iPhone and iPad calculation hub for arithmetic, fractions, unit and currency conversion, reusable history, photo/OCR-assisted solving, and focused reference tools.

Data stored on the device

The app can store calculation, conversion, and tool history, including the expression or input, result, type, favorite state, and creation time. It also stores language and appearance preferences, a locally cached currency-rate snapshot and its freshness date, and the edited text that you choose to keep while using the solving workflow. The default history limit is controlled in Settings and is 500 entries unless you change it. These records are kept in the app’s local container.

Photos, camera, and OCR

PhotosPicker and the camera are used only after you choose photo solving. The selected image is processed for text recognition on the device. Recognized text is placed in an editable field before solving. The app does not automatically upload the original image or recognized text. If you explicitly enable a compatible external solving endpoint and actively retry, the app sends only the text you confirm, not the original image. The external response is shown as a reference and may be incomplete or wrong.

Network and configured services

Core arithmetic, fractions, unit conversion, focused tools, and history do not require a network connection. When you actively refresh currency data, the app may request a reference-rate snapshot from its configured rate service and stores the last valid snapshot locally. If refresh fails, the existing or bundled reference remains and the app reports the failure. Optional semantic solving is disabled by default. When enabled, the endpoint and any access key are supplied by you; the key is kept in the device Keychain and the service processes data under its own terms and privacy policy.

Apple services and permissions

The app uses Apple frameworks for local storage, PhotosPicker, camera permission prompts, Vision text recognition, Keychain storage, App Intents, accessibility, and system interface presentation. It does not request location, contacts, microphone, HealthKit, or notification permission in this release. Apple processes system permissions and services under Apple’s own terms. Shortcuts can invoke the local Calculate, Convert Units, and Convert Currency actions.

What we do not collect

The current app has no account system, cloud history, advertising SDK, analytics SDK, tracking, social profile, or server database for your local records. It does not sell or use your local calculations, images, OCR text, tool inputs, or history for advertising. The app is not directed to children and does not provide a medical, fertility, investment, payroll, tax, or legal service.

Retention, deletion, and exports

You control local history in Settings, including the clear-history action and the configured history limit. You can remove the optional service endpoint and clear its access-key field. Working image data is used for the selected recognition task and is not saved by the app as a photo record. Files you copy, export, or share are controlled by the destination you choose. Device backups and third-party endpoints are outside the app’s control.

Accuracy and security limits

Local-first storage reduces unnecessary transmission but cannot guarantee absolute security or recovery from device loss, reset, corruption, or a service failure. Currency values are references, and the focused health, finance, work, and cycle tools are estimates. Use your own judgment and appropriate professional advice where needed.

Changes and contact

We will update this policy when data handling, permissions, services, or product scope materially changes. For privacy questions or deletion support, contact [email protected].

超级计算器隐私政策

更新日期：2026 年 9 月 3 日

本政策适用于超级计算器（Super Calculator），一个面向 iPhone 与 iPad 的本地优先计算中枢，提供四则与科学计算、分数、单位和汇率换算、本地历史复用、照片/OCR 辅助解题和专用参考工具。

保存在设备本地的数据

App 可以在本机保存计算、换算和工具历史，包括表达式或输入、结果、类型、收藏状态和创建时间，也会保存语言与外观偏好、汇率参考快照及新鲜度日期，以及你在解题过程中选择保留的可编辑文字。历史条数上限可在设置中调整，默认是 500 条。这些记录保存在 App 的本地容器中。

照片、相机与 OCR

只有在你主动选择照片解题后，App 才会使用 PhotosPicker 或相机。所选图片会在设备端进行文字识别，识别文本会先进入可编辑输入框。App 不会自动上传原图或识别文本。如果你明确启用兼容的外部解题地址并主动重试，App 只发送你确认后的文字，不发送原图。外部服务返回的内容只作为参考，可能不完整或不正确。

网络与已配置服务

核心计算、分数、单位换算、专用工具和历史记录不需要联网。你主动刷新汇率时，App 可能向配置的汇率服务请求参考快照，并将上一次有效快照保存在本机。刷新失败时，App 会保留已有或内置参考数据并显示失败状态。可选语义解题服务默认关闭；启用时，服务地址和访问密钥由你提供，密钥保存在设备钥匙串，服务商按自己的条款和隐私政策处理数据。

Apple 服务与权限

App 使用 Apple 框架提供本地存储、PhotosPicker、相机权限提示、Vision 文字识别、钥匙串、App Intents、无障碍和系统界面能力。本版本不请求定位、通讯录、麦克风、HealthKit 或通知权限。Apple 按自己的条款处理系统权限和服务。快捷指令可以调用本地的计算、单位换算和汇率换算动作。

不会收集什么

当前版本没有账户系统、云端历史、广告 SDK、统计 SDK、追踪、社交资料或用于保存本地记录的服务器数据库。App 不出售本地计算、图片、OCR 文本、工具输入或历史记录，也不将其用于广告。本 App 不面向儿童，也不提供医疗、生育、投资、薪酬、税务或法律服务。

保留、删除与导出

你可以在设置中控制本地历史，包括清空历史和条数上限。你也可以移除外部服务地址并清空访问密钥输入框。临时图片数据只用于本次识别，App 不会把它保存成照片记录。你复制、导出或分享的文件由你选择的目标应用或位置控制。设备备份和第三方服务不在 App 控制范围内。

准确性与安全限制

本地优先可以减少不必要的传输，但不能保证绝对安全，也不能保证设备丢失、重置、损坏或服务失败后一定恢复。汇率是参考值，健康、金融、工作和周期工具是估算结果；需要时请结合自己的判断和适当的专业意见。

变更与联系

当数据处理、权限、服务或产品范围发生重要变化时，我们会更新本政策。如有隐私问题或删除支持需求，请联系 [email protected]。
