Your projects, sessions, and documents live in your Qufy account. The Mac app keeps only what it needs to work on this Mac, in the places below.
Your sign-in: in the macOS Keychain, as the item with service studio.qufy.desktop and account session. If the Keychain refuses it, the sign-in is kept in memory only until you quit Qufy.
In ~/Library/Application Support/studio.qufy.desktop: qufy-time.json holds your app settings and the actions waiting to sync (project ids, times, and notes), with no sign-in token. widget.json holds what the widgets show: project names, amounts, and your last sessions. Both files can be read only by your Mac user account.
The log: ~/Library/Logs/studio.qufy.desktop/qufy.log (moved to qufy.old.log when it reaches 256 KB). It records start-up steps, load times, sign-in steps, Keychain and sign-out results, and window errors. It never records tokens or notes.
macOS also keeps caches for the app's window in ~/Library/Caches and ~/Library/WebKit/studio.qufy.desktop.
Good to know
- Links that start with qufy:// from a browser or another app can only open Qufy. They cannot start, stop, or change your timer.
- The widget is sandboxed by macOS and can read only its one file, widget.json.
- Signing out removes your sign-in from the Keychain. To remove everything else, follow the steps to uninstall the app.
