Android 7 users: app might not work properly on your device, please switch to "Calendar Notifications Plus" (see my other apps).

Description for "Sticky Calendar":

This app will keep Google Calendar notifications until the your dismiss them

This app would keep calendar event notifications from disappearing after event time has passed. Reboot is handled also - all notifications are restored after reboot, so event notifications are fully persistent and staying until manually dismissed.

App works by removing original notification and replacing with similar looking one from its own.

App only works with Google Calendar and only event notifications are handled by this app. There is no need to handle reminders - they don't disappear.
