An accountability group that fits in a room.

Yes. One identity can be in any number of rooms: one with your partner, one with friends, one with the family. Tap the room name on the Room tab (or Settings, Room, Your rooms) to switch, start another room or join one with a link or code. Anyone can start a room, whether or not they are an admin somewhere else. Each room has its own habits, its own name and look for you, and its own admins; nothing crosses over between rooms. Rooms you joined on another device appear after tapping the refresh line in that list.

A room link contains the room secret, so anyone with the link can join and see everything. Send it directly to the person you want in the room, in a private channel, and avoid posting it anywhere public. By default only admins see the link, the code and the QR and can invite; in a couple both of you are admins, in other rooms an admin can make someone else an admin or open invites to everyone under Settings, Room. The member list there shows who has joined.

If a link has reached someone it should not have, open Settings and renew the invite link under Room. Everyone already in stays in; old links, codes and QR codes stop working. Admins can also remove a member there.

A streak counts consecutive scheduled days (or periods, for habits like “3 times a week”) that you completed. Skipping a day with a reason neither breaks nor extends the streak. Missing a day breaks it, unless the habit has the forgiving streak turned on: then one missed day per week counts as skipped and the streak continues. You can turn this on or off per habit in the habit editor.

When you first open Jatkuu, your device creates a key pair. The public key is your identity in a room; the private key never leaves your device and signs every change you make, so nobody can act as you. There is nothing to log in to, so there is no password to remember or leak. Your backup is a 12 word recovery phrase that you can show, copy or save as a file in Settings.
