DeepSeek's privacy policy, updated February 10, 2026, names Hangzhou DeepSeek Artificial Intelligence Co., Ltd. in China as the controller, and it lists foundation-model training and optimization as a reason personal data may be shared with service providers. It also gives you a right to opt out of training. That is a consumer privacy right, not a business plan where training is off by default. Do not put business data in the DeepSeek chat apps.
