Open questions
Questions the captured policies leave unanswered, and where the answer probably lives.
Muse Privacy Policy (muse.ai/privacy) is referenced but not captured. It likely covers Muse retention periods, sharing, data location, human review and legal terms.
The 'How Muse works with Connectors' help page isn't captured. It would say what connector data is stored and what happens on disconnect.
No captured policy gives a deletion timeline for Meta AI or Muse (how long until deleted data is gone, including backups). The Meta AI Privacy Center guide (facebook.com/privacy/guide/genai) and the Meta Privacy Policy 'Learn more' subpages on retention would likely say.
Output ownership and the license Meta gets in your content aren't in the AI Terms. Both are likely in the Meta Terms of Service (facebook.com/terms.php), which isn't captured.
Whether the Meta AIs Terms of Service govern Muse isn't stated. Muse-specific terms would answer this.
Regional AI Terms (UK, EU, Brazil) and the US Regional Privacy Notice aren't captured.
The privacy policy's 'Where is information transferred?' and 'AI integrations' subsections are collapsed in the captured policy. Their expanded text would say more about data location and AI third-party sharing.
The AI partners page (facebook.com/privacy/dialog/ai-partners) isn't captured. It would name the search partners and say what is shared with them.
