Before you start
A few questions, clear answers
Can I use Notban without signing up?+
Yes. Notes, checklists, labels, reminders, locks and backups all work on your phone without signing in, even offline. Signing in with your mobile number is only needed to sync across devices, share and keep version history.
What happens when I’m offline?+
Notban is offline-first: every change is saved on the device right away and syncs automatically once you’re back online. If two people edit the same note’s text at once, nothing is lost; a conflict copy is created.
How do I share a note?+
Open the note menu, tap Share and enter the person’s mobile number with view-only or edit access. Even if they don’t have Notban yet, they’ll see the note after their first sign-in. You can share several notes at once too.
Do attached images and files sync?+
Not yet. Attachments stay on the device and are included in the encrypted backup file and in Word exports. Text, checklists, labels and note settings do sync.
What if I lose my phone?+
Sign in with the same number on another phone or on this website. Your synced notes come back, and from Active devices you can sign the lost phone out.
Which languages and calendars are supported?+
Persian, Arabic and English, with right-to-left and left-to-right layouts; Solar Hijri, lunar Hijri and Gregorian calendars; light and dark themes and adjustable font size.
