Privacy & Data Handling in Google Antigravity: What Happens to Your Code?

When using AI-powered IDEs, privacy is a top concern. This guide explains exactly how Google Antigravity handles your code, what data is sent to servers, and how to protect your intellectual property.

How Antigravity Uses Your Code

What Gets Sent to Gemini 3

When you use AI features, Antigravity sends:

• Current file content (or selected portion)
• Context files (referenced imports, types)
• Project structure (file names, not contents)
• Your prompt/question

What Stays Local

• Files in .antigravityignore
• Environment variables
• Git credentials
• MCP server credentials
• Build outputs
