Sold as a download

macOS (signed & notarized) · Windows (installer not yet code-signed) — a desktop app, licensed to you for good. One purchase covers both platforms. The copy you download is yours to keep and will go on working whether or not we do: it runs entirely on your machine, with no subscription and no server on our side. Re-downloads live in your account for as long as the store does, so keep your own copy of anything you rely on.
