Local notes. Offline after activation.
Local by default
Native notes stay on your Mac. Koala does not require an account, and note content is not sent to Koala servers.
Offline after activation
Activation needs an internet connection once. After that, Koala verifies its licence locally and works offline.
Backups you choose
Export a backup archive from the app menu, then import it later to move or restore your notes.
