 **Notifications** (the bell on Home and Family): a list of what you have not seen yet: chat messages (one line per conversation, with a count), reminders for tasks, events and mail, and family announcements. Tap one to open it; mark all read or clear. Kept per person in `inbox.json`.

 **Name tiles on the sign-in page:** on a device you have remembered (Settings → Family → *Remember this device*, or any family device) the sign-in page shows everyone's name, children marked KID. Tap yours, then enter your PIN (it signs in as soon as the last digit is typed) or use your passkey; a child with no PIN just taps. Any other browser still shows only *Sign in with passkey*, so strangers see no names and cannot guess PINs. A remembered personal device gets a normal long session; a family device keeps its short sessions. *Forget* switches it off again.
 
 **Family devices** (Settings, under Passkeys): for a kitchen tablet or the family computer. An admin turns on *Make this a family device* while signed in on it; from then on it opens on the **family board** (announcement, today's family calendar, chores with progress, shopping list, family tasks and notes) and a row of name tiles, children marked **KID**. Tap your name: a child signs in with one tap, everyone else enters a PIN they set in Settings (five wrong tries lock that person for five minutes; there is also a passkey link). A label with your name and **Switch user** stays on screen, and the device goes back to the board after five idle minutes (music playing keeps it signed in). Sessions on a family device last 30 minutes at a time, not months. Turn it off from the same place. Each board card has a **+** to add to the shopping list, the family tasks, a shared checklist (pick which) or the Family calendar (all day, or at a time): write it, tap your name (PIN unless you are a child) and it is added as you, if that part of the hub is turned on for you. Chores on the board are tappable: tap one (up-for-grabs chores ask *I did it* or *Take it for later*), tap your name, and enter your PIN if you are not a child; the chore is then done or claimed as you, with all the usual chore rules, without signing in. The admin picks who appears on the board (a **Show on the family board** switch in each person's settings; people left off do not get a tile or show in family chore progress). The Family calendar and Family task list are shared by everyone and appear on the board.
