Atrium Browser Lite

# 🔒 Atrium Browser Lite
Atrium Browser Lite automatically detects and masks sensitive information before prompts are sent to AI assistants and chat platforms.

Whether you're a developer, consultant, founder, analyst, or everyday AI user, accidental data exposure can happen in seconds. Atrium reduces that risk by protecting information before it leaves your browser — locally, with zero telemetry.

# 🌍 Choose What You Protect
Pick the regions and privacy regimes you care about (GDPR, HIPAA, UU PDP, PDPA, Privacy Act) — or simply enable Global mode. Only the detectors you choose will run.

# ⚙️ How It Works
Atrium inspects outgoing prompts on supported AI platforms and replaces sensitive values with safe placeholders before submission.

Examples:
[john@example.com](mailto:john@example.com) → [[EMAIL_1]]
081234567890 → [[PHONE_1]]
sk-proj-xxxxxxxx → [[API_KEY_1]]

Optionally, original values can be restored inside the AI response so the model remains useful while the platform never receives your actual data.
