What DeepSeek's privacy policy and terms of service say about your data
Training opt-out is named but not explained
The policy states "the right to opt-out of using your Personal Data for training our models" without describing how the opt-out is exercised. The right is named, though no concrete mechanism sits behind it.
Access right has no mechanism or deadline
The policy offers "the right to access your Personal Data" as a bare statement. No request route, response deadline or data format is specified.
Correction right sits beside an accuracy disclaimer
The policy states "the right to correct inaccuracies in your Personal Data" in general terms. It later disclaims that the factual accuracy of Outputs cannot be guaranteed.
Explicit refusal to sell or profile
The policy states "NOTE WE DO NOT ENGAGE IN TARGETED ADVERTISING, SELL PERSONAL DATA OR USE PERSONAL DATA FOR PROFILING". That is an explicit non-engagement clause rather than a vague assurance.
What the policy is silent or vague on
- Not stated: whether training use differs by plan
- Not stated: shorter retention for AI conversation logs
- Not stated: a sub-processor list or data processing agreement
- Not stated: limits on special-category data
