本地免费，云端可选。
序流是一款本地优先的笔记应用。笔记存在你自己的设备上，不注册也能用。需要多设备同步时，再开云端——只为容量付费，功能不打折。
Free on your device.
Cloud when you want it.
Ordflux is a local-first note app. Your notes live on your own machine and work fully offline, no account required. Turn on Cloud Sync only when you want them on more than one device — you pay for space, never for features.
