+## Auto Log Cleanup
+
+Enable Auto Log Cleanup to automatically delete the oldest logs once the default storage limit of 10 million logs is reached, ensuring that new logs are always saved without needing manual deletion. Logs are deleted in chunks of 0.1% of the storage limit, which equates to 10,000 logs at a time.
+
+This setting is useful for maintaining continuous logging while staying within the default storage constraints.
