Make sure MouseTrail is running (look for the trail icon in the menu bar), then move the mouse — the trail only appears while the pointer is moving. The classic rainbow trail, including its length and width, works for everyone with no purchase required.
看不到轨迹怎么办？请确认 MouseTrail 正在运行（菜单栏中有轨迹图标），然后移动鼠标——轨迹仅在指针移动时显示。经典彩虹轨迹（包括长度和粗细调节）无需购买，人人可用。
Click the menu bar icon > Settings > Trail. Rainbow mode's length and width sliders are free for everyone and apply live. Fixed colors, multi-color gradients, and saving your own presets require MouseTrail Pro — a single one-time purchase (from $9.99 USD, no subscription).
如何更改轨迹颜色、长度或粗细？点击菜单栏图标 > 设置 > 轨迹。彩虹模式的长度与粗细滑块人人可免费使用，调整即时生效。固定颜色、多色渐变以及保存自定义预设则需要 MouseTrail Pro——单次一次性购买（9.99 美元起，无需订阅）。
Toggle "Launch at Login" in the menu bar menu (or in Settings > General). It's on by default after the first launch.
如何在登录时自动启动？在菜单栏菜单（或设置 > 通用）中开启"登录时启动"。首次启动后默认开启。
If you bought MouseTrail Pro as the one-time purchase, there's nothing to cancel — it's a single charge, not a recurring one. If you'd like a refund, that goes through Apple directly at reportaproblem.apple.com. If you're on the older MouseTrail Pro subscription from before this change, it keeps renewing as usual and you can still manage or cancel it any time: open the App Store app > click your name > Account Settings > Subscriptions, or System Settings > Apple ID > Media & Purchases > Subscriptions.
需要取消 MouseTrail Pro 吗？如果您购买的是一次性的 MouseTrail Pro，无需取消——这是单次扣费，不会重复收费。如需退款，请直接通过 Apple 的 reportaproblem.apple.com 办理。如果您是在本次调整前购买了 MouseTrail Pro 订阅，订阅仍会照常续费，您可以随时管理或取消：打开 App Store 应用 > 点击您的姓名 > 账户设置 > 订阅，或系统设置 > Apple ID > 媒体与购买项目 > 订阅。
No. Your subscription keeps working exactly as before, with no action needed on your part. You don't need to buy the new one-time Pro unlock, and you can still manage or cancel your subscription any time via Apple's subscription settings (see above).
我在此次更新前就已订阅，需要做什么吗？不需要。您的订阅将完全按原样继续生效，无需任何操作。您不必购买这次新增的一次性 Pro 解锁，也可以随时通过 Apple 的订阅设置管理或取消订阅（见上）。
Open Settings > Pro and click "Restore Purchases" while signed in to the same Apple Account you bought with. This works for both the one-time Pro purchase and a legacy subscription.
在另一台 Mac 上购买过 Pro，如何恢复？使用购买时的同一个 Apple 账户登录后，打开设置 > Pro，点击"恢复购买"。无论是一次性购买的 Pro 还是旧版订阅，都可以这样恢复。
Settings > Trail > Export… saves your presets as a .mousetrailpack file anywhere you choose (including cloud drive folders). Use Import… on any Mac to bring them back; your presets also survive deleting and reinstalling the app automatically.
如何备份或分享预设？设置 > 轨迹 > 导出…可将预设保存为 .mousetrailpack 文件（可存至任意位置，包括云盘文件夹）。在任何 Mac 上用导入…恢复；即使删除并重装应用，预设也会自动保留。
No. Everything runs locally on your Mac — see the Privacy Policy.
MouseTrail 会收集数据吗？不会。一切都在您的 Mac 本地运行——详见隐私政策。
