Sigma Computing's privacy policy provides strong legal rights (access, deletion, portability, correction, opt-out) but is silent on AI model training, output ownership, and security controls beyond industry-standard assertions.
What Sigma Computing's privacy policy and terms of service say about your data
Critical Finding: D1.1–D1.4 Contained Wrong Policy
The original ledger quoted Claude's training language ("training our models, unless you opt out", "Outputs") which does NOT appear in Sigma's policy. Sigma Computing's privacy policy is silent on model training, LLM use, and output ownership, it governs a cloud analytics platform, not an AI service. D1.1, D1.2, D1.4 all downgraded to zero.
D3.4 Downgraded to Half
Original quote about "aggregation and de-identification techniques" does not appear verbatim; actual policy text says "we may disclose or use aggregated or de-identified information or data for any purpose", vague commitment without minimization mechanism detail, hence half not full.
D4.2 Upgraded to Full
Original award was half; policy explicitly requires third parties to "abide by contractual, technical, and organizational measures" with named scope: "processed only to the extent that such processing is necessary, consistent with this Privacy Notice, and in accordance with applicable law", named mechanisms present, merits full.
D4.3 Upgraded to Full
Original award was half; policy clearly states "if you opt out, going forward, we will not disclose your Personal Data to third parties (including Advertising and Marketing Partners) for the purposes of online analytics, targeted advertising, or cross-context behavioral advertising", negative covenant with no-opt-out carve-out, merits full.
What the policy is silent or vague on
- Not stated: keeping user inputs out of model training
- Not stated: a way to opt out of training
- Not stated: whether training use differs by plan
- Not stated: your ownership of generated outputs
