Answers to the common questions. For anything else, write to contact@montana.one.
How do I sign in?
On the first page choose Continue with Montana, then Create: your identity is made from 24 words on the phone itself and needs neither a number nor an e-mail address.
Do I need a phone number or an e-mail address?
No. The 24 words are your whole identity: the app asks for no phone number and has no sign-in by e-mail.
I have a new phone. How do I bring my account back?
With your 24 words: on the first page choose Continue with Montana, then Open identity, and enter them. If the words are kept in the iCloud Keychain, a phone signed in with the same Apple Account offers the identity without typing.
How do I leave?
In Settings → Privacy, Delete account erases the 24-word identity on the phone, and deleting the app removes everything it stored. Montana keeps no directory of people, so nothing of yours remains on our side.
How do I report abuse?
Long-press any received message and choose Report, or open the person's card and choose Report or Block. Reports are reviewed within 24 hours.
