DeepSeek: data residency & retention
Headquarters
🇨🇳 China (China)
Where inference runs
China
The privacy policy states personal data is collected, processed, and stored in the People's Republic of China — all API data is processed and stored in mainland China.
Region pinning
No
No region selection, non-China hosting option, or residency commitment appears in the privacy policy, platform terms, or API docs.
Prompt retention
Retained
Prompts are retained as long as necessary to provide services and for interests including service improvement — no fixed window; context caching on disk is on by default with no documented off switch.
Trains on API data
Yes, by default
One policy covers app and API without carve-out: user input is used to train and improve models; opt-out only by emailing privacy@deepseek.com — no console toggle for API traffic.
Zero data retention
Not offered
No zero-data-retention option exists in any official DeepSeek document.
