MouseTrail is a macOS menu bar utility that draws a colorful, fading trail behind your mouse pointer so it is easier to spot on screen. MouseTrail is built privacy-first: the app operates completely locally on your Mac, has no account system, no analytics, and no backend server. This policy explains what the app does and does not do with information on your device.
MouseTrail 是一款 macOS 菜单栏小工具，会在鼠标指针后绘制一条渐隐的彩色轨迹，让您更容易在屏幕上找到指针。MouseTrail 以隐私优先的方式构建：应用完全在您的 Mac 本地运行，没有账户系统、没有数据分析、也没有后端服务器。本政策说明应用如何处理（以及不处理）您设备上的信息。
We do not collect, store, or transmit any personal information. MouseTrail has no analytics, no tracking, no advertising identifiers, and makes no network connections of its own.
我们不收集、不存储、也不传输任何个人信息。MouseTrail 没有数据分析、没有跟踪、没有广告标识符，自身也不进行任何网络连接。
MouseTrail Pro is a one-time purchase (a Non-Consumable in-app purchase, priced from $9.99 USD — price may vary by region) that permanently unlocks fixed colors, gradients, and custom preset styles. There is no subscription and no recurring charge for new purchases, and no free trial. All payments are processed entirely by Apple through your App Store account; we never see or store your payment details, Apple ID, or billing information. Your entitlement status (whether Pro is unlocked) is verified with StoreKit and cached only on your device, so the app also works offline. If you subscribed to MouseTrail Pro before this change, your subscription keeps working exactly as before — you do not need to buy the one-time unlock, and you can still manage or cancel it at any time in your App Store account settings.
MouseTrail Pro 现为一次性购买（App 内购买中的非消耗型项目），售价 9.99 美元起（不同地区价格可能不同），购买后即可永久解锁固定颜色、渐变色以及自定义预设样式。新购买不涉及订阅，也没有周期性扣费，同样没有免费试用期。所有付款均由 Apple 通过您的 App Store 账户处理，我们绝不会看到或存储您的付款信息、Apple ID 或账单信息。您的解锁状态通过 StoreKit 验证，并仅缓存在您的设备上，以便应用在离线时也能正常工作。如果您在本次调整前已订阅 MouseTrail Pro，您的订阅将完全按原样继续生效——无需购买这次新增的一次性解锁，您也可以随时在 App Store 账户设置中管理或取消订阅。
Your trail settings and custom presets are stored locally on your Mac (in the app's preferences and the macOS Keychain, so your presets survive reinstalling the app). If you export presets as a .mousetrailpack file, that file is created only at your request and saved to the location you choose; sharing it is entirely under your control. The "Launch at Login" option is a standard local macOS setting.
您的轨迹设置和自定义预设存储在您的 Mac 本地（保存在应用偏好设置和 macOS 钥匙串中，因此重新安装应用后预设仍会保留）。如果您将预设导出为 .mousetrailpack 文件，该文件仅在您主动操作时生成，并保存到您选择的位置；是否分享完全由您决定。"登录时启动"选项是标准的 macOS 本地设置。
MouseTrail uses no third-party services. The only external service involved is Apple's App Store for purchases, which is governed by Apple's Privacy Policy.
MouseTrail 不使用任何第三方服务。唯一涉及的外部服务是用于购买的 Apple App Store，其受 Apple 隐私政策约束。
MouseTrail runs inside the macOS App Sandbox. Since no data leaves your device, your information is protected by your Mac's own security: preferences live in the app's sandboxed container and presets are protected by the macOS Keychain.
MouseTrail 运行在 macOS 应用沙盒中。由于任何数据都不会离开您的设备，您的信息由 Mac 自身的安全机制保护：偏好设置保存在应用的沙盒容器中，预设由 macOS 钥匙串保护。
MouseTrail collects no data from anyone, including children.
MouseTrail 不收集任何人的数据，包括儿童。
If we ever change how MouseTrail handles data, we will update this policy and the "Last updated" date above before the change takes effect.
如果 MouseTrail 的数据处理方式发生变化，我们会在变更生效前更新本政策及顶部的"最近更新"日期。
