The letter stated that the data involved includes source code, system architecture, database credentials, and cloud service tokens. It demanded Zhipu to clarify the data storage, cross-border transmission, third-party sharing, and model training usage, as well as to completely delete the related data from servers, caches, and backups, and provide access logs and proof of deletion.
