Subscription

Sievesmith is free to download. Without a subscription you can add one server, open, edit, format and check its scripts (locally and on the server), keep drafts and export backups.

Sievesmith Pro unlocks uploading, creating, renaming, deleting and activating scripts, more than one server and the Git mirror. It is a yearly subscription, for you alone or for your family (Family Sharing, up to six people), and starts with a free trial. One subscription covers Mac, iPhone and iPad.

Manage or cancel it in the App Store under your account’s subscriptions; Settings › Subscription shows the state. If a purchase is not recognized, choose Subscribe… and then Restore Purchases. The demo server works without a subscription.
