No, there are no expiration dates.
However, for security reasons, projects that do not have any instances (regardless of whether they are running or stopped) within the project for a continuous period of 30 days will be gradually deleted. (Instances: Solr, general-purpose instances, paid dedicated crawlers)
In such cases, registered "Extensions" in the project will also be deleted. Therefore, if necessary, please create a new project and register the extensions to the project again for use.
