When you create an event in Proton Calendar(new window), you can set up notifications to alert you about the event before it occurs. You can also edit the event to add notifications after it has been created.
To receive notifications on the desktop, they must be manually enabled in your browser.
However, if you have the Proton Calendar app installed on your Android device, iPhone, or iPad, then you will receive Calendar notifications automatically via Android and iOS’ built-in notification systems.
