Privacy Policy
Last updated: March 14, 2026
Overview
Phantom is a voice-powered AI browser assistant built as an open-source Chrome extension. Your privacy is a core design principle, not an afterthought.
Data We Collect
Phantom collects no personal data. Specifically:
- No accounts or sign-ups required
- No analytics, tracking, or telemetry
- No cookies on our website (except essential ones)
- No user data is stored on our servers
How the Extension Works
When you use Phantom, the following data flows occur:
- Voice audio is streamed to Google's Gemini API via our WebSocket proxy for real-time conversation. Audio is not stored.
- Screen captures (when vision is enabled) are sent to Gemini for understanding page context. These are not stored.
- API keys (if using BYOK mode) are stored locally in your browser's extension storage and never sent to our servers.
- Memory and embeddings are computed and stored entirely in your browser using a local model. They never leave your device.
- Session summaries are generated via our server but stored only in your browser's local storage.
Privacy Shield
Before any screenshot is sent to the AI, Phantom's Privacy Shield automatically detects and blurs sensitive content including:
- Passwords and credit card numbers
- API keys and tokens
- Social Security Numbers and personal identifiers
- Email addresses and phone numbers
Third-Party Services
Phantom uses the following third-party services:
- Google Gemini API — for AI conversation and understanding. Subject to Google's API Terms.
- Google Cloud Run — hosts the WebSocket proxy server. No user data is persisted.
Open Source
Phantom is fully open source. You can audit every line of code on GitHub.
