# Expiration Recycling

## Alert

The billing system will send alarm notifications to customers.

Resources recycled manually by the account manager: An alarm will be sent to the customer within 10 minutes.

Automatically recycled resources:

- Monthly or yearly billing: An alarm is sent on the 1st day in the morning, once on the 3rd day, and once on the 6th day;
- Hourly billing: The next alarm is at 10 o'clock.

### Renewal

If you renew within 7 days after the alarm is issued, you can continue to use it normally, and the original configuration is retained.

## Recycling strategy

If you have not renewed after the alarm is issued, the resource will be deleted 7 days after the first alarm is issued.

## User Deletion

If the user deletes the WAF during its use, a corresponding fee for the current month's used time will be charged, and the remaining fee will be returned to the user's account.
