What DeepSeek's privacy policy and terms of service say about your data
Training opt-out is a real switch
Inputs and outputs feed model development by default, but the terms point to a named control, "Improve the model for everyone", that users can turn off, and a separate right to opt out of training is listed among user rights.
Output rights go to the user
Users keep whatever rights they have in their inputs, DeepSeek assigns output rights to the user, and the terms explicitly permit reusing outputs for personal use, research, derivative products, and training other models.
No retention clock anywhere
The policy keeps data "for as long as necessary" and names no retention period, no deletion timeline after account closure, and no shorter clock for chat logs.
Data is stored in China with soft transfer language
The policy states data is collected, processed, and stored in the People's Republic of China and promises only "appropriate safeguards" for cross-border transfers without naming a legal mechanism.
What the policy is silent or vague on
- Not stated: whether training use differs by plan
- Not stated: a deletion timeline after closure or request
- Not stated: shorter retention for AI conversation logs
- Not stated: a sub-processor list or data processing agreement
