DecHex 隐私政策

最后更新日期：2026 年 11 月 7 日（适用于 1.0.6 及以后的版本）

DecHex（以下简称「本应用」，包括其小组件和控制中心按钮）尊重并保护你的隐私。本政策说明本应用如何处理你的信息。

一、我们不收集任何个人信息

本应用不收集、不上传、不存储任何可识别你个人身份的信息。具体而言：

• 本应用不联网，没有任何网络请求，不存在把数据发送到服务器的能力
• 不要求注册、不要求登录、不索取手机号、邮箱或任何账号信息
• 不接入任何第三方统计、广告、崩溃收集或社交 SDK
• 不申请任何系统权限，不读取你的通讯录、相册、位置、麦克风、相机、健康等任何敏感数据

二、本应用在本机保存的内容

为了在你下次打开应用时恢复上次的状态，本应用会在你自己的设备本地保存以下内容：

• 当前输入的数字、运算符与计算结果，计算历史（两个计算器各一份）
• 配色主题、数字字体、千分位分隔符、应用图标配色、键盘布局、位宽等偏好设置
• 按键震动、按键声音、计算结果记忆的开关状态
• 上次停留的页面

这些数据通过 iOS 系统提供的本地存储（UserDefaults）保存在应用沙盒内，不会离开你的设备，我们无法访问。你可以随时长按 CLR 关闭记忆功能（会立即清除已保存的计算状态和历史），或直接卸载本应用来彻底删除全部数据。

三、小组件与控制中心

为了让主屏幕、锁定屏幕小组件和控制中心按钮的颜色跟随你选择的主题，本应用会把当前主题的几个颜色值写入本机的 App Group 共享存储，供本应用自己的小组件读取。共享的只有颜色值，不包含任何计算内容，也不会离开你的设备。

四、Siri 与快捷指令

你可以通过 Siri 或「快捷指令」让本应用转换进制、计算表达式。你说出或输入的数字和表达式由系统交给本应用，在本机完成计算后把结果返回给你，本应用不会保存或上传这些内容。语音识别由 Apple 的 Siri 处理，适用 Apple 的隐私政策。

五、剪贴板

只有在你主动操作时，本应用才会访问剪贴板：点按「复制」按钮或在长按菜单中选择「复制」时，把对应内容写入剪贴板；在长按菜单中选择「粘贴」时，读取剪贴板中的文本并解析为数字。除此之外本应用不会读取剪贴板。

六、不需要服务器，也不涉及 ICP 备案

七、儿童隐私

本应用不收集任何用户数据，因此也不存在收集儿童个人信息的情况。年龄分级为 4+。

八、数据共享

由于本应用不收集数据，不存在向任何第三方出售、出租或共享用户数据的情形。

九、政策变更

如果未来版本引入需要处理数据的新功能，我们会在本页面更新本政策，并在应用更新说明中提示。

十、联系我们

DecHex Privacy Policy

Last updated: November 7, 2026 (applies to version 1.0.6 and later)

DecHex (the "app", including its widgets and Control Center button) respects your privacy. This policy explains how the app handles your information.

1. We do not collect personal information

• The app does not use the network. It makes no network requests and cannot send data to any server
• No sign-up, no login, and no phone number, email address or account information is requested
• No third-party analytics, advertising, crash reporting or social SDKs are included
• No system permissions are requested. Contacts, photos, location, microphone, camera, health and other sensitive data are never accessed

2. What the app stores on your device

To restore your work the next time you open it, the app stores the following locally on your own device:

• The current input, operators and results, and the calculation history of each calculator
• Preferences such as theme, number font, thousands separator, app icon color, keypad layout and word size
• The on/off state of key haptics, key sounds and result memory
• The page you last used

This data is kept in the app's sandbox using the iOS local storage (UserDefaults). It never leaves your device and we cannot access it. Long press CLR to turn off result memory (this immediately clears the saved state and history), or delete the app to remove all data.

3. Widgets and Control Center

So that the Home Screen and Lock Screen widgets and the Control Center button match your theme, the app writes a few color values of the current theme to an on-device App Group container that only the app's own widgets read. No calculation data is shared, and nothing leaves your device.

4. Siri and Shortcuts

You can ask Siri or use the Shortcuts app to convert number bases or calculate expressions. The numbers and expressions you provide are passed to the app by the system, calculated on your device, and the result is returned to you. The app does not save or upload them. Speech recognition is handled by Apple's Siri and is subject to Apple's privacy policy.

5. Clipboard

The app accesses the clipboard only when you ask it to: tapping a Copy button or choosing Copy from a long-press menu writes that value to the clipboard, and choosing Paste reads the clipboard text and parses it as a number. The clipboard is not read at any other time.

6. Children's privacy

The app collects no user data, so it collects no personal information from children. It is rated 4+.

7. Data sharing

Because the app collects no data, no user data is sold, rented or shared with any third party.

8. Changes to this policy

If a future version adds a feature that processes data, this page will be updated and the change will be noted in the release notes.
