so a power outage would not disable it

seems like the DS3231 RTC module currently used does not include RAM :-/

we might store information into the Arduino EEPROM https://www.arduino.cc/en/Reference/EEPROM

Storing alarm there would make sense when it is changed (avoid writing too often to the EEPROM)

we might as well store the alarms into the... alarm registers of the DS3231 http://forum.arduino.cc/index.php?topic=277605.0

would also provide the user the possibility to shut it down without bad consequence
