What DeepSeek's privacy policy and terms of service say about your data

D1.2 downgrade

Marked "full" for named opt-out mechanism, but "the right to opt-out of using your Personal Data for training our models" is boilerplate naming without concrete implementation. Downgraded to "half" per rubric: adjectives/named-but-vague = half at most.

D2.1 downgrade

Marked "full" for access right, but "the right to access your Personal Data" is a bare statement with no mechanism, deadline, or format specification. Downgraded to "half" per rubric: stated rights without substance = half.

D2.4 downgrade

Marked "full" for correction right, but "the right to correct inaccuracies in your Personal Data" is vague boilerplate. Policy later disclaims: factual accuracy of Outputs cannot be guaranteed. Downgraded to "half" per rubric.

D4.3 affirmed as full

"NOTE WE DO NOT ENGAGE IN TARGETED ADVERTISING, SELL PERSONAL DATA OR USE PERSONAL DATA FOR PROFILING" is an explicit named non-engagement clause that meets full award criteria.
