Explanation of the permissions:
Control vibrator: Used for the alarm to vibrate the phone with the desired vibration pattern
Disable standby modus: Used to make sure that the screen isnâ€™t turned off during alarm
Phone calls / read phone state: This is to not interrupt active calls by the alarm and to stop the alarm when a phone call comes in.
Read calendar events: This is to get the time, title and location from the event when an alarm is raised.
Modify calendar events: When an alarm is snoozed my app has to store a new reminder for the event. This is stored in the calendar database.
Retrieve running applications: Used by the home helper to get the Launchers which can be associated with the home key
Set preferred apps: Used by the home helper to replace the launcher for the home key
Test hardware: Used to set the screen brightness for flashing screen

Works under Android 6.0?
Yes works, but you have to disable the battery optimization under Android power options.
did you try to disable the battery optimization for CER under Android power options? I’m using CER on an HTC One M8 under MM and this helped to make the app reliably again.
Yes, I disabled battery optimization for CER, and it did nothing. I still miss events.
I also tried disabling battery optimization for Google Calendar just in case there was some dependency.
Josh, OK. Could you please also try to deactivate battery optimization for the apps ‘Calendar storage’ and ‘Google Calendar sync’? If this doesn’t help I would recommend to deactivate it for all apps in order to find out if this has anything to do with it. Besides that I know that some Marshmallow devices suffer from bugs in the Android system that Google needs to solve. But let’s hope it’s something about the battery optimization.
Google calendar sync doesn’t appear at all under battery optimization. But I’ve turned off optimization for Calendar, CER, and calendar storage.
That didn’t help.
Is there a way to turn off optimization for all apps at once? I only know how to do it one app at a time. If I have to do it that way, I’d prefer to start with other apps that you suspect might be involved.
I don’t think this is battery optimization changes in Marshmallow. In addition to the fact that I’ve turned off battery optimization for a large number of apps at this point, CER notifications ate also not appearing at times when Doze is not (or should not be) on. I can be using the phone, or moving around with it in my pocket, and I still won’t get a reminder.
I love CER and have been using it for years. I recently got a Nexus 6P and installed CER. Everything seems to work perfect except the default calendar reminders are not being surpressed properly. So I end up getting the CER notification and also the default Google Calendar notification.
Is there a workaround for this?
Also is it required to disable battery optimization for CER to work on newer versions of Android? I didn’t know about this until I read through some recent comments here. It would be worthwhile to update your FAQ and also proactively notify new user upon install that this is needed.
CER has stopped working. Android version G930VVRS4CRG2. Power saving mode is OFF. Are there any other global setting I should check?
I may have found the answer. I have a Galaxy S7. Under Settings > Device maintenance > Battery > Unmonitored apps , add CER.
