What OmniFocus leaves behind
Specific to OmniFocus
Dragging the app to the Trash does not delete your documents or support folders. Your task database, backups, and settings remain in sandboxed containers, occupying between 100 MB – 1 GB. These include separate containers for different versions and a sandbox script folder. You must manually remove these via the hidden Library folder to complete the uninstallation.
- License
- OmniFocus is licensed through an Omni account subscription, a license key or the App Store.
- Account and sync
- OmniFocus can sync through an Omni Sync Server account; without sync the database exists only on this Mac.
Preparing to remove OmniFocus
Because the app stores its entire database locally, deleting the containers will permanently erase any unsynced tasks. Ensure all data is uploaded to your Omni Sync Server account if you use one. Otherwise, manual backups are necessary since the database exists only on this Mac. Remember that custom perspectives are also part of this database.
