Terms of Service
Last updated 2026-11-12
Who we are
Pulsar is a system monitor for macOS, developed and published by an independent developer ("we"). These terms cover the Pulsar app, the website pulsarmac.app and any Pulsar license you buy. By installing Pulsar or buying a license you agree to them.
The free edition
The free edition of Pulsar may be used at no cost, for personal or commercial work, on any Mac you own or control. Features included in the free edition stay free.
Pro licenses
Licenses are not on sale yet. This section and the Payments and Refunds sections apply from the day sales open.
A Pro license is a one-time purchase, not a subscription. It unlocks the Pro features of Pulsar for one person on up to two Macs at a time. You can deactivate a Mac in the app to move the license to another one.
After checkout, the license key is emailed to the address you paid with. You enter it in Pulsar's Settings and activate it over the internet; Pro features unlock as soon as activation succeeds. If the email does not arrive, write to us and we will resend the key.
A Founding license or a Supporter license includes every future update to Pro features. A Standard license includes updates to Pro features for one year from purchase; after that year, the Pro features you already have keep working, and you can choose to buy again to receive newer ones.
A license is for you. Do not resell, publish or share license keys. We may disable keys that have been refunded, charged back or published.
Early access and trial
Until licenses go on sale, Pulsar is in early access: Pro features are open to everyone and no trial clock runs. From the day sales open, each Mac gets 14 days of the full Pro experience without sign-up. When that ends, Pulsar continues as the free edition.
Payments
Purchases are processed by Dodo Payments, our reseller and merchant of record. Dodo Payments handles payment, tax and invoicing, and its own terms apply to the transaction. Prices are listed in US dollars and exclude any tax that applies where you live; tax is shown at checkout.
Refunds
You can ask for a full refund within 14 days of purchase. See the Refund Policy.
Acceptable use
Pulsar reads system state and, when you ask it to, sends signals to processes on your Mac. Use it only on computers you are authorised to manage. You may not reverse engineer the license checks, or redistribute modified copies of the app.
Updates
Pulsar can check pulsarmac.app for new versions and install them after you confirm. You can turn the automatic check off in Settings.
No warranty
Pulsar is provided as is. Its readings come from interfaces macOS exposes and may be incomplete; the known limits are documented. Quitting or force-quitting a process can lose unsaved work in that process, and that decision is yours. To the extent the law allows, we are not liable for indirect or consequential loss, and our total liability is limited to the amount you paid for your license.
Changes
We may update these terms. The date above shows the latest version; material changes are announced in the release notes. A license you have already bought keeps the entitlements it was sold with.

服务条款
最后更新 2026-11-12
关于我们
Pulsar 是一款 macOS 系统监控工具，由独立开发者（下称「我们」）开发并发布。本条款适用于 Pulsar 应用、网站 pulsarmac.app 以及你购买的 Pulsar 许可。安装 Pulsar 或购买许可即表示你同意本条款。
免费版
Pulsar 免费版可以无偿使用，个人与商业用途均可，可安装在你拥有或管理的任意 Mac 上。免费版包含的功能永久免费。
高级版许可
许可尚未开售。本节以及「付款」「退款」两节自开售之日起适用。
高级版许可为一次买断，不是订阅。一份许可供一人使用，可同时在两台 Mac 上激活；在应用内停用其中一台后，可在另一台上重新激活。
结账完成后，许可密钥会发送到付款时填写的邮箱。在 Pulsar 的设置中输入密钥并联网激活，激活成功后高级功能随即解锁。没有收到邮件时请来信，我们会重新发送密钥。
创始许可与支持者许可包含高级功能此后的全部更新。正式版许可包含自购买之日起一年内的高级功能更新；一年期满后，已获得的高级功能继续可用，如需更新的功能可再次购买。
许可仅供购买者本人使用，不得转售、公开或共享许可密钥。已退款、被拒付或被公开的密钥，我们可以将其停用。
抢先体验与试用
许可开售之前，Pulsar 处于抢先体验阶段：高级功能对所有人开放，不计试用时间。自开售之日起，每台 Mac 获得 14 天的完整高级版体验，无需注册。试用结束后，Pulsar 以免费版继续运行。
付款
购买由我们的经销商 Dodo Payments 处理，它是交易的记录商户（Merchant of Record），负责收款、税务与发票，该笔交易同时适用其条款。价格以美元标示，不含你所在地区适用的税费；税费在结账时显示。
退款
购买后 14 天内可申请全额退款，详见退款政策。
使用规范
Pulsar 读取系统状态，并在你主动操作时向本机进程发送信号。请只在你有权管理的计算机上使用。不得对许可校验进行逆向工程，也不得再分发修改后的应用。
更新
Pulsar 可以向 pulsarmac.app 检查新版本，并在你确认后安装。自动检查可在设置中关闭。
免责声明
Pulsar 按现状提供。它的读数来自 macOS 开放的接口，可能不完整；已知的限制有文档说明。结束或强制结束进程可能导致该进程中未保存的内容丢失，是否执行由你决定。在法律允许的范围内，我们不对间接或附带的损失负责，赔偿总额以你为许可支付的金额为限。
条款变更
我们可能更新本条款。页首的日期为最新版本的日期；重要变更会在更新说明中公布。已购买的许可保留其出售时所含的权益。
