Notifications
Mobile push only, device registration, and the per-member schedule that controls when it arrives.
upzero delivers notifications as push notifications to the mobile app. There is no other channel: no email, no SMS, no Slack, no webhooks, for an ordinary notification. This is a deliberate V2 decision, not a gap waiting to be filled.
Device registration
Install the mobile app and sign in. Your device registers for push automatically, there is nothing to configure by hand.
Your schedule
Every member controls their own notification schedule under Settings → Schedule, so a notification at 3am reaches whoever is actually on call rather than the whole team at once.
| Mode | Behaviour |
|---|---|
| Always | Notify whenever something happens |
| Scheduled | Notify only inside the days and time window you define |
| Never | Silence everything |
Choosing Scheduled reveals which days it applies to, a start and end time, and the timezone those times are read in.
Always notify for critical incidents overrides the schedule so a genuine outage reaches you outside your window, and while set to Never. It is on by default. Turning it off means Never silences critical notifications too, and a critical notification raised outside your window waits until the window opens, so this is the one control where the safe direction to be wrong in is stated plainly rather than left to guess.
Escalation pages are a different kind of notification
An escalation policy page is not subject to the schedule above at all, on purpose. It bypasses your quiet hours and Do Not Disturb unconditionally, including if you have turned off the critical override, because a quiet-hours setting that can silence the one delivery guarantee the system has would defeat the point of paging someone in the first place. Every bypassed delivery is still recorded, so "why did I get this at 2am" is answerable from your notification history.
Email as a non-response and pile-up fallback exists only inside the escalation path described on the escalation policies page. It is never a channel you select here.
