> Help that applies to every LonelyDuck app you buy: licenses and your Macs, orders and refunds, and updates.

Applies to Canto 1.0 beta 3 and Tulip 2.0 beta 2 · Updated Oct 10, 2026 · https://lonelyduck.io/docs/general

These pages cover what Canto and Tulip share: how a license works on your Macs, buying, receipts and refunds, and how updates and betas reach you. Each app's own guide covers the rest.
