What you lose and keep with Insomnia

Specific to Insomnia

Removing the application bundle does not delete local projects or settings, which stay in ~/Library/Application Support/Insomnia. Only projects stored locally in this folder are at risk if you later clear it, while cloud or Git-synced collections remain safe in their respective accounts. The app’s preferences and caches persist independently of the executable.

Where your Insomnia data lives

These folders hold your own Insomnia data. Deleting the app leaves them in place; removing them is what actually deletes it.

~/Library/Application Support/Insomnia App data · local vault data, request history, plugins and caches Back up first: your data

Account and sync: Projects can be stored locally, in cloud sync or in a Git repository; only local projects depend on this folder.
Your files: Local projects are stored as database files inside the Insomnia support folder.

Preparing to remove Insomnia

Deleting the app itself is reversible via the Trash, but emptying the Trash permanently removes the executable. If you intend to clear all traces, you must separately delete the support folder containing your local database files. Ensure you have backed up any local-only collections before proceeding with folder deletion.

Export local projects and collections using the in-app export option.Identify and note which projects are local versus synced to Git or cloud.Copy any custom plugins from the plugins folder to a backup location.Quit the application completely before attempting to remove any files.

Frequently asked questions

Will deleting Insomnia delete my files?

No. Removing the app doesn't touch documents you saved in other folders. Only the app and, if you remove them, its own support files are deleted.

Will I lose my unsynced projects if I only delete the app?

No, the application bundle and your local data are separate; data persists until you manually delete the support folder.

Can I recover deleted local projects after emptying the Trash?

No, once the support folder is deleted and the Trash is emptied, local database files are permanently lost unless backed up.
