Proton Calendar notifications — overview and default settings

Proton Calendar can send you reminders (notifications) to alert you about upcoming events. There are two kinds of notifications:

• Push notifications — Banners or other notifications that appear in your desktop browser or on your mobile device (Android and iOS)
  • Learn more about Proton Calendar desktop browser notifications
  • Learn more about Proton Calendar mobile notifications
• Email notifications — Emails that are sent to your inbox
  • Learn more about Proton Calendar email notifications

You can add notifications to Proton Calendar events in two ways:

• Add default notifications — Notifications that will be automatically added to all events you create in a particular calendar.
• Add event-specific notifications — Notifications for a specific event.

Here we explain how Proton Calendar notifications work in general on the Proton Calendar web app:

How notifications behave in different types of calendar events

Notifications for shared calendar events you’re invited to

When you receive and accept an invitation to an event in Proton Calendar, the event is added to your default calendar. The event will have the default notification(s) that you set for that calendar. You can edit event-specific notifications anytime.

Any notifications on events you’re invited to remain private to you. For example, the notifications below are only for you.

Note that you can only edit a shared calendar event on the web and Android apps. You can’t currently edit a shared calendar event on Proton Calendar for iPhone or iPad (iOS/iPadOS).

Notifications for shared calendar events you invite others to

Similarly, any notifications you add to events you’ve organized with invited participants remain private to you. For example, the notifications below are only for you.

The event in the participants’ calendars will have their own calendar’s default notifications or any notifications they’ve added manually.

Notifications for shared calendars

Likewise, if you share a calendar with other Proton users, any notifications you add remain private to you. The person you share the calendar with has their own notifications.

Notifications for external calendars

You can add default calendar notifications to external calendars you’ve subscribed to via a URL. The default notifications you add will be applied to all events in the calendar.

You can’t add event-specific notifications to external calendars you’ve subscribed to via a URL.

To add default notifications to an external calendar:

1. In Proton Calendar, click the horizontal three dots next to the calendar you want to edit and select Edit. 

2. Click Add notification under event notifications (for events at a specific time of day) or all-day event notifications (for events lasting all day).

3. Click Save when you’re done.

You can add up to five default event notifications and up to five default all-day event notifications.
