Does DeepSeek API (Open Platform) train on your data?
Not stated
Vendor pages don't say clearly.
The Open Platform terms checked do not say whether API inputs are used for training. The consumer privacy policy says it does not cover data from apps built on the open platform.
Why this matters: Unknown doesn't mean no. Ask DeepSeek to confirm in writing before sharing confidential data, because training can't be undone. Why training matters →
