• Offline operation: The software is not connected to the Internet and functions entirely within the local environment of the hospital PC. No data is transmitted externally.

• Data storage and protection: Patient information is stored locally in a Microsoft SQL Server–based database, which is encrypted according to MS-SQL security protocols. This ensures protection of personal data from unauthorized access.

• System independence: The device and the software are functionally independent — hospitals may record or transfer results manually into their internal hospital information systems (HIS/LIS) if preferred.

• Security classification: According to internal development standards, the software complies with Level B information security requirements under Chinese cybersecurity regulations, which corresponds to standard safeguards for non-networked hospital software systems.
