DuoDeck

Terms of Use

Updated 9 November 2026

The product

DuoDeck lets a paired iPhone or iPad interact with a compatible Mac. A Mac, the companion app and the permissions required for capture and input are necessary for its core functions. It is not a system-wide trackpad for unrelated iPhone apps.

Use

Use DuoDeck with computers and accounts you own or have permission to control. You manage your trusted devices, network and optional VPN or remote-access configuration.

Open source

DuoDeck includes software derived from the Apache 2.0 licensed Sill project. The applicable license, warranty provisions and retained copyright notices are available in the source repository. These terms do not restrict rights granted by those licenses.

Availability

Features depend on the operating-system version, device and connection. Release notes and distribution-channel records describe the actual available builds. The current website does not sell subscriptions, and the native local-control experience does not require a DuoDeck account.

Support
