Privacy Guard Extension Privacy Policy

Last updated: September 11, 2026

Overview

This policy covers the Aladdin Privacy Guard Chrome extension (MV3). The extension helps you detect and tokenize sensitive data before sending prompts to AI chat services such as ChatGPT, Claude, and Gemini.

We do not collect, store, or sell your raw prompts or PII on our servers. Detection and token mapping run locally in your browser.

Data processed locally (never uploaded)

  • Prompt text you paste into the side panel or protect via the in-page Shield button
  • Token mappings (e.g. <EMAIL_1> → original value) stored in IndexedDB on your device only
  • PII detection via regex, rules, and optional enhanced NER — all in-browser

Optional Shield API

If you configure an API key in extension Settings, you may send already-tokenized prompts to Aladdin's Shield proxy (/api/v1/shield/chat/completions). In that case:

  • Only placeholder text (e.g. <PERSON_1>) is transmitted — not originals
  • Token mappings remain on your device
  • We log metadata only (model, token count, timestamp) — never prompt or response text
  • Requests are forwarded to third-party LLM providers (OpenAI, Anthropic, etc.)

Without an API key, the extension works fully offline for detection and copy/paste workflows.

Host permissions

The extension requests access to:

  • chatgpt.com, claude.ai, gemini.google.com — to inject the local Shield button and read/write the chat input field when you click it
  • aladdin-agent.net (and localhost in dev) — for optional Shield API and custom rules sync

We do not read page content unless you explicitly click the Shield button.

Storage & retention

  • chrome.storage.sync — API base URL and API key (if you provide one)
  • IndexedDB — token mappings until you clear them or uninstall the extension
  • No cloud backup of token mappings

Third-party services

When using Shield API, prompts are forwarded to LLM providers under their respective privacy policies. Aladdin does not use your data for model training.

Children

The extension is not directed at children under 13.

Changes

We may update this policy. Continued use after changes constitutes acceptance. Material changes will be reflected in the extension version notes.
