Core tasks in mental health & psychology

GLM (Z.ai) raises a concrete GDPR concern. Parent company Zhipu (Beijing) is subject to Chinese data and security legislation, regardless of where the servers are located. For sensitive data, self-hosting the MIT-licensed weights is the recommended mitigation. Weigh this heavily before using it in mental health & psychology.

Confidentiality and GDPR

GDPR: Caution

Mental health records contain special category personal data (health data, GDPR). Only use systems with 7510 certification, a data processing agreement and EU hosting; audio recordings of therapy sessions must not be sent unencrypted to external servers. AI-supported diagnostics and treatment decisions fall under the EU AI Act (high risk) and require human oversight and an audit trail. A BIG-registered professional remains ultimately responsible for the content of the record.

The international service Z.ai runs through JINGSHENG HENGXING TECHNOLOGY PTE. LTD. (Singapore); personal data is in principle processed in Singapore. According to the data processing agreement, API content is processed in real time and not stored. GLM-5.2 is open-weight under MIT and can therefore be fully self-hosted or hosted through an EU provider.

Rule of thumb Use the business variant with a data processing agreement, and keep a human in the loop for decisions that matter.
