Judgment Layer — Privacy Policy

Last updated: April 27, 2026

Summary

Judgment Layer is a Chrome extension that drafts email replies in your personal voice. All processing happens locally in your browser using on-device AI models. We do not collect, transmit, sell, or share any of your email content, drafts, or personal data. There are no analytics, tracking, or telemetry of any kind.

1. What the Extension Accesses

  • Gmail thread content — Read locally to provide context to the on-device model when drafting a reply. Never transmitted off your device.
  • Hugging Face model files — The extension downloads open-source AI model weights from huggingface.co on first use. Only model files are downloaded; no user data is sent in the request.
  • Local browser storage — Your generated drafts, learned style preferences, and extension settings are stored locally in Chrome storage on your device.

2. What We Do Not Do

  • We do not transmit email content, drafts, or thread context to any server.
  • We do not collect analytics, usage telemetry, or crash reports.
  • We do not use cookies or tracking pixels.
  • We do not share, sell, or rent any data to third parties.
  • We do not use your data to train models. All learning happens on your device.

3. On-Device Processing

All AI inference (drafting, style learning, classification) runs locally in your browser via WebAssembly and on-device model runtimes. Your email content never leaves your machine. If you uninstall the extension, all locally stored data is removed by Chrome.

4. Permissions Justification

  • Host permission for mail.google.com — Required to read the active email thread so the on-device model can draft a contextually appropriate reply.
  • Host permission for huggingface.co — Required to download open-source AI model weights on first install. Only static model files are fetched; no user data is sent.
  • storage — Stores your drafts and style preferences locally.
  • sidePanel — Renders the extension UI in Chrome's side panel.
  • offscreen — Runs the on-device model in a background context so inference does not block the page.
  • scripting — Injects the Gmail content script when you open a Gmail tab.

5. Third Parties

The extension fetches model weights from Hugging Face. These requests contain only the model file path and standard browser headers; no personal data or email content is included. Hugging Face's privacy policy governs that interaction.

6. Data Deletion

All extension data lives in your browser's local storage. Uninstalling the extension or clearing Chrome extension data removes everything. There is no server-side data to delete because we do not have servers.

7. Changes

We may update this policy. Material changes will be reflected on this page with a new “Last updated” date.
