I have no intention of buying a monthy/yearly sub for the alarm system. Can I still use the app? Will the app still send me notification? Will I still be able to customize and change the Alarm system through the app?
Good question @GB11! Alarm users can choose between Professional Monitoring and Self Monitoring anytime. If you are not subscribed to a Protect Plus Plan, you will only be able to sel monitor, as professional monitoring requires subscription. Check out our help center article about monitoring to see the benefits and processes for each monitoring type.
When not subscribed and self monitoring, you may still use the Ring app and will still receiving notifications of certain Alarm events. There are many features still available in self monitoring, however, cellular backup is only a feature with the Protect Plus subscription. I hope this helps!
