Description

It would be useful to add an event when Haven is manually activated, and another event when Haven is manually deactivated. Also, I'm not sure if this is currently implemented, but it would be useful for there to be an event when the phone shuts down due to low battery, and an event when the app closed (because someone is powering off the phone for example) but not deactivated or because of low battery.

I think having these extra events will make users more sure of themselves. And if you come back to find Haven not activated, you'll have evidence that it's because you just forgot to activate it rather than because someone tampered with the phone while you were away.

Research direction
Investigate the existing event handling in the Haven Android app. Look at the MainActivity and any service classes to understand how manual activation/deactivation is currently implemented. Then, add new events (likely through Android's EventBus or custom listeners) for manual activation, manual deactivation, low battery shutdown, and app close. Ensure events are triggered at appropriate points in the lifecycle.
