Confidentiality and GDPR

GDPR: Caution

Be transparent that customers are speaking with AI and ensure a smooth handover to an employee. Protect the privacy of customer data in conversations.

The DeepSeek service stores data in China and uses it for training by default (with an opt-out). Only an EU self-hosted variant of the open weights is defensible for sensitive data.

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