隐私政策
单位随手换（Handy Units）
单位随手换是一款单位换算工具，不需要注册账号，也不会向你索要姓名、手机号或邮箱。
一、我们收集的信息
在你同意本政策后，App 会通过「友盟+」统计 SDK 收集匿名的使用统计，用来了解 App 的使用情况并改进功能：
- 设备信息：设备型号、操作系统版本、App 版本、设备标识（IDFV，以及友盟保存在私有粘贴板中的 OpenUDID）、屏幕尺寸、运营商、网络类型、IP 地址（用于判断大致地区）。
- 使用情况：启动次数和使用时长，以及换算的分类和单位、切换分类、复制、分享、编辑常用分类、打赏提示是否出现等操作事件。你输入的具体数值不会上传。
我们不申请广告标识符（IDFA），也不读取你的精确位置、通讯录、相册，或你复制到剪贴板的内容。
二、第三方 SDK
三、只保存在本机的信息
你的设置、常用分类、输入的数值和换算次数只保存在本机（以及本机的小组件）中，不会上传。
四、汇率
为了显示汇率，App 会从单位随手换汇率服务或 ExchangeRate-API / Frankfurter 下载公开的汇率表，请求中不含任何个人信息。
五、打赏
打赏完全由 Apple 通过 App Store 处理，我们看不到你的支付信息。
六、你的选择
- 你可以随时在「设置 › 使用统计」关闭统计，关闭后 App 不再上报任何使用数据，所有功能照常可用。
- 不同意统计不会影响任何功能的使用。
- 如需查询或删除已上报的数据，请发送邮件至 aquilawang0625@gmail.com 联系开发者。
本政策如有重大变化，App 会再次征求你的同意。
Privacy Policy
Handy Units
Handy Units is a unit converter. It needs no account and never asks for your name, phone number or email.
1. What we collect
After you agree to this policy, the app uses the Umeng+ analytics SDK to collect anonymous usage statistics, so we can see how the app is used and improve it:
- Device information: device model, OS version, app version, device identifiers (IDFV and OpenUDID, which Umeng keeps in a private app pasteboard), screen size, carrier, network type, and IP address (used to estimate the region).
- Usage: launches and session length, and events such as the category and unit of a conversion, switching categories, copying, sharing, editing favorites and whether the tip prompt was shown. The numbers you type are never uploaded.
We do not request the advertising identifier (IDFA), and we don’t read your precise location, contacts, photos, or anything you copy to the clipboard.
2. Third-party SDK
- SDK: Umeng+ U-App analytics (UMCommon, UMDevice)
- Provider: Umeng Tongxin (Beijing) Technology Co., Ltd.
- Purpose: usage statistics
- Data: see “Device information” and “Usage” above
- Umeng+ privacy policy: https://www.umeng.com/policy
3. Kept only on your device
Your settings, favorite categories, the values you type and your conversion count stay on this device (and in its widgets). They are not uploaded.
4. Exchange rates
To show exchange rates, the app downloads a public rate table from our rate service or from ExchangeRate-API / Frankfurter. These requests contain no personal data.
5. Tips
Tips are processed entirely by Apple through the App Store. We never see your payment details.
6. Your choices
- Turn off Settings › Usage Statistics at any time; the app then stops reporting and every feature keeps working.
- Declining statistics never limits any feature.
- To ask about or delete reported data, email the developer at aquilawang0625@gmail.com.
If this policy changes materially, the app will ask for your consent again.
