Microsoft Copilot discloses basic AI identity and data access rights, but trains on user data with opt-out, grants itself broad perpetual rights to outputs, and lacks specificity on data processors, international safeguards, and children's governance.

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

Training with Opt-Out

Conversation data trains generative AI models unless user opts out; opt-out mechanism not specifically named, only referenced as "additional privacy choices" in product settings

Output Ownership Risk

Microsoft can copy, distribute, sublicense, and give outputs to third parties indefinitely ("we can give those same rights to others who work on our behalf") with no time limit or user control

Deletion & Retention

Users can delete individual conversations (removed immediately, back-end deletion within 30 days), but overall retention policy is only "for as long as reasonably necessary" (vague)

Data for Advertising

Policy states data used "to provide relevant advertising" with no explicit opt-out mechanism for ad-specific uses, unlike Anthropic's commitment to non-sale

What the policy is silent or vague on

Not stated: whether training use differs by plan
Not stated: your ownership of generated outputs
Not stated: data portability
Not stated: a retention period for your data
