NeutrinoPrivacy Policy
Neutrino does not collect any data.

The app
Neutrino stores your to-do list as a file on your Mac, in a location you control. The app has no accounts, no analytics, no advertising and no tracking, and it does not send your list or any other information to us or to anyone else.
If you choose to keep your list in a folder synced by a service such as iCloud Drive, Google Drive or Dropbox, that service handles the file under its own privacy policy. Neutrino itself only reads and writes the file on your Mac.

If you email us, we use your address and message only to reply to you.
