### The theft alarm

*Every 30 seconds while you use Raven*

If money leaves a wallet between two reads and Raven did not send it, you get an alert naming the wallet and what left.

| | |
|---|---|
| While you use Raven | Every 30 seconds |
| When you come back | At once |
| While you are away | Every 2 minutes, with the alarm on |
| Raven’s own moves | Never alarm |

## Backup reminder

While a key is in no backup yet, Raven shows a line asking you to make one. See [Backup and recovery](https://ravenwallet.pro/docs/backup).

## Under the hood

- **How it knows**: Raven compares each read with the last one. Money that left without a move in [Activity](https://ravenwallet.pro/docs/activity) is money Raven did not send.
- **Reads, not keys**: The alarm only reads balances by address. It works while the vault is locked.
