How to uninstall Termius on Mac

Termius keeps your hosts, groups, snippets, keys and identities in an encrypted vault. With an account and a subscription the vault syncs to Termius's cloud; without one, or with the credentials sync toggle off, Termius's documentation says those credentials stay only on this Mac. Before removing the app, confirm on another device that the hosts and keys you need are there, or copy out any SSH key that exists only in Termius. The steps cover Termius's disk image and the Homebrew cask termius.

Do not log out before uninstalling

Termius's documentation says logging out clears all local data, and credentials that were not synced cannot be recovered afterwards. Removing the app is a separate step and does not need a logout. If you want to keep a local-only vault for a reinstall, leave the data folder below in place.

Quit Termius and remove the app

  1. Close open sessions and quit Termius from the Termius menu.
  2. Search Activity Monitor for Termius and check that its processes have exited. In the recorded test Termius ran seven processes, which Mole's Status page folded into one row.
  3. Move Termius from Finder's Applications folder to the Trash.

Removing the app does not cancel a Termius subscription or delete your account. Termius schedules a deleted account for removal and keeps it restorable for 30 days, as described in its account management page.

Where Termius keeps its data

Press Shift + Command + G in Finder and check each location. Skip paths that do not exist.

Location What it holds What to do
~/Library/Application Support/Termius The app's own data folder; Termius does not document its contents, so treat it as your local vault Keep it while any host or key exists only on this Mac; remove it last
~/.termius Listed in the Homebrew zap list; Termius does not document its contents Look inside before removing it
~/Library/Logs/Termius App logs Safe to remove after quitting
~/Library/Saved Application State/com.termius-dmg.mac.savedState Saved window state Safe to remove after quitting

Check the result

Run these read-only commands after the app is in the Trash:

pgrep -il termius
ls -d "$HOME/Library/Application Support/Termius" ~/.termius
  • No output from pgrep means no Termius process is running. A listed process means the app is still open; quit it before touching its data.
  • ls -d prints each folder that still exists and reports "No such file or directory" for the rest. A surviving Application Support/Termius is expected if you kept a local vault; it is not a failed uninstall.

If you installed it with Homebrew

The termius cask's zap list is ~/.termius, ~/Library/Application Support/Termius, ~/Library/Logs/Termius and the saved window state. brew uninstall --cask --zap termius moves them to the Trash, local data included. The cask's plain uninstall step also deletes /Library/Preferences/com.termius-dmg.mac.plist, a preferences file outside your home folder.

To keep the local data, remove only the app:

brew uninstall --cask termius

Mole adds --zap only when every path on the zap list sits inside ~/Library, none of them touches a row you left unchecked, and no other installed app claims them. ~/.termius is outside ~/Library, so Mole never adds --zap for this cask: it runs the plain command above and removes only the leftovers you selected. A brew command you type yourself never consults Mole's checkboxes.

What Mole lists

For Termius from its disk image:

  • ~/Library/Application Support/Termius is listed but not selected. The Chromium cache folders inside it, such as Cache, Code Cache and GPUCache, are separate rows selected by default.
  • ~/Library/Logs/Termius, when it exists, is selected by default. Mole can also list ~/.termius, taken from Homebrew's zap list for this app, but does not select it.
  • Caches, preferences and saved window state filed under com.termius-dmg.mac are selected by default.

Mole cannot tell whether your vault has synced, so it never selects the data folder for you.

What this test covered

On September 19, 2026, Termius was copied from its disk image into Applications, opened, and uninstalled with a Preview build of Mole 1.15. There was no Homebrew receipt. ~/Library/Application Support/Termius was listed, left unselected and stayed on disk. On September 26, 2026, Termius 10.1.0 from its disk image was installed again and removed with a development build of Mole with every row ticked: the app and 12 listed items went to the Trash, Application Support/Termius included, and nothing from the list remained. No account sign-in, sync, SSH session or Homebrew install was tested.
