“Real people at AI companies may be reading your private chats — here's how to protect yourself”

Key points

• AI conversations may be reviewed by humans to improve models or ensure safety.
• OpenAI, Google, Microsoft and Anthropic outline human review policies for chats.
• Deleting chats may not erase all copies immediately; retention varies by company.
• Google Gemini chats can be kept for up to three years even after deletion.
• Users can adjust settings, but opt-out does not guarantee complete privacy from reviewers.
