DeepSeek's privacy policy states personal data, including prompts, is directly collected, processed, and stored in the People's Republic of China, and may also be stored on servers outside a user's home country. Users have a stated right to opt out of having their data used for training or optimizing DeepSeek's technologies; the policy does not describe this as off by default for API traffic, so training is recorded as on by default here unless a customer opts out. No specific retention period in days is published, and no zero data retention offering, HIPAA BAA, SOC 2, or FedRAMP authorization is stated.

Where you can call it
- direct Retired name; requests using deepseek-chat stopped resolving at 15:59 UTC on 2026-07-24. During the transition window it pointed to the non-thinking mode of deepseek-v4-flash.
deepseek-chat was the alias for DeepSeek-V3's non-thinking mode before the V4 migration. Its per-model documentation page was withdrawn on retirement, so context window, max output tokens, and release date have no first-party source and are not published here.
