Technical details

What Promo Desk is built with and how it treats your files. For people who like to know what runs on their Mac.

Built with

Part	What we use
Language	Swift 6 (strict concurrency)
Interface	SwiftUI, with AppKit for open panels and Quick Look
Project	Swift Package Manager — the app logic lives in a separate module with its own tests
System	macOS 14 Sonoma or later · Apple silicon and Intel
Third-party code	None. No SDKs, no analytics, no ad or tracking libraries

Your files

Promo Desk reads only the folders you choose. The Mac App Store build is sandboxed and keeps access with security-scoped bookmarks, so it cannot open anything else.
Your listing files are read, never rewritten. The one exception: when you press Mark as posted on a post file, Promo Desk updates that file's status: line.
Ticks, folder list and settings are JSON files in Promo Desk's own Application Support folder, written atomically. Export Settings puts them in one file you can move to another Mac.

Network

Sync Knowledge downloads a public GitHub repository of marketing guides (read only, nothing is sent).
Buttons such as Open App Store or Open X only open a page in your browser.
The optional Claude panel starts the Claude Code program you installed yourself, signed in with your own account. Promo Desk has no server of its own.

Listing files

Plain Markdown: one ## Field name heading per store field, the value below it. Promo Desk recognises fields for 19 stores and 17 launch sites, and flags placeholder text so it never reaches a store.
