DuoDeck

Privacy Policy

Updated 9 November 2026

Your devices, connected directly

DuoDeck connects an iPhone or iPad to a Mac companion. Screen frames, optional audio, clipboard text and control input travel between your devices over the connection you configure. The current native apps do not use a DuoDeck cloud relay, hosted account database, advertising SDK or analytics SDK.

Permissions

The Mac companion uses Screen Recording to transmit a chosen window or desktop, and Accessibility to deliver pointer and keyboard actions. The iOS app uses local-network access for discovery and camera access when you choose to scan a pairing code.

Information kept on your devices

Pairing identities, trusted devices, preferences and saved connection information are stored locally. The app can retain a thumbnail of your last session for its saved-Mac view. You can remove saved Macs and paired devices in the apps. Operating-system keychain items can remain after an uninstall; removing the app alone does not guarantee that every pairing credential is erased.

Your choices

You can disconnect at any time, disable clipboard or audio sharing, remove paired devices and revoke permissions in system settings. Remote Access is optional and uses the network or VPN configuration you supply.

This website

The website uses local storage to remember your interactive-preview layout, shortcut set and pointer speed. These preferences remain in your browser. Choose Reset preview to restore their defaults or clear site data in your browser to remove them. Ordinary HTTP request metadata may be processed by the hosting infrastructure to serve the site. The site currently has no account sign-in, advertising or analytics integration.

Optional update checks

When you check for updates, manually or automatically, DuoDeck Host contacts GitHub to check DuoDeck release information. GitHub receives the request IP address and the app version included with the request. Automatic checks are enabled by default and can be turned off in Overview › Updates.

External links and contact

GitHub, Apple and other linked services apply their own privacy policies. Product source, support information and issue reporting are available in the DuoDeck repository.
