What are the terms for termination of the service under Circularo's Terms of Service?

The Terms remain effective until the subscription expires or is terminated by either party. If you terminate, it takes effect at the end of your current subscription period. Circularo may terminate with 14 days' notice for a breach or immediately for serious violations or legal reasons. Upon termination, your access to services and related licenses ends, all outstanding payments must be settled, and your content will be deleted 30 days after the termination date.
