Terms of use (as of 2026-03-27, section 4.3): DeepSeek may use inputs and outputs 'to a minimal extent', after encryption and de-identification, to improve the services and the underlying technologies; opt-out available by switching off 'Improve the model for everyone'. Privacy policy: data is used, among other things, to train and improve the models; right to object to use for training. Document 'Model Mechanism and Training Methods of DeepSeek': in the optimisation phase, a small portion of the training data may be based on user input, which is then encrypted, de-identified and anonymised.

The Open Platform terms (effective 2026-04-29) govern ownership of inputs and outputs (the customer retains rights to inputs and receives rights to outputs) but contain no express statement on the use of API inputs for training; they refer to the document 'Model Principles and Training Methods Explanation', which likewise does not distinguish between chat and API. The terms of use (section 4.3) and the privacy policy apply to 'Services' in general; an API-specific opt-out is not described. For end-user data in its own applications, according to the privacy policy and the Open Platform terms (5.5), the developer is the controller.
