Automatic service deactivation
One-time deactivation: To prevent unnecessary charges, Security Center will be automatically deactivated for pay-as-you-go users who have not used the service for 15 consecutive days. This deactivation will occur during the upcoming price adjustment window.
It is a one-time protective measure, not a recurring policy. You can re-enable the service at any time via the console.
If you are sure that you no longer need Security Center, manually disable the pay-as-you-go features to avoid future charges.
We are committed to delivering clearer, more transparent, and flexible security services. Your feedback helps us improve. If you have questions, please contact customer service.
Thank you for your continued trust and support.
