Data Guard Privacy Policy

Browser extension for ChatGPT, Claude and Gemini · Effective 28 October 2026

In short

Who this policy is for

Data Guard is an internal tool for Jazz employees. It works only after you sign in with your Jazz Microsoft 365 account. This policy explains what the Data Guard Chrome extension does with your information. It covers the extension and the Data Guard server it talks to. It does not cover ChatGPT, Claude or Gemini themselves, which have their own privacy policies.

What the extension handles

The extension runs only on chatgpt.com, chat.openai.com, claude.ai and gemini.google.com. It does nothing on any other website and does not read your browsing history.

Prompts you send

When you send a prompt on one of those sites, the extension sends its text to the Data Guard server. The server replaces sensitive details with placeholders and returns the masked text. Only the masked text goes to the AI site.

Files you upload

When you attach a file on one of those sites, the extension sends it to the Data Guard server, which returns a masked copy. Only the masked copy is uploaded to the AI site; the original is never handed to it. If masking fails, nothing is uploaded. To confirm the AI site accepted the masked copy, the extension looks for its file name on the page; that check happens in your browser and sends nothing anywhere.

The AI's answers

When an answer contains placeholders, the extension sends that text to the Data Guard server, which returns it with the real values put back. The restored answer is shown on the page in your browser. It is not sent back to the AI site.

Your sign-in

You sign in with Microsoft, in Microsoft's own window, either from the extension or on the Data Guard console. The extension never sees your password. Microsoft returns a token that confirms who you are; the extension passes it once to the Data Guard server and does not keep it. The server then sets a sign-in cookie, which the extension cannot read. That cookie identifies you (by your work email address) to the Data Guard server, so that only you can restore what you masked. A sign-in lasts 8 hours.

Your choices in the extension

Your on/off choices (detect tables, restore answers automatically, show the on-page button) are saved with Chrome's storage. If you use Chrome sync, Chrome syncs these choices to your other devices. They contain no personal information.

Custom terms you type (extra words to always mask) and the link between each chat and its masking session are kept only in your browser's memory. They are never written to disk, never synced, and are erased when you close the browser.

Where your data goes

Prompts, files and answers travel only between your browser and the Data Guard server at data-guard.jazz.com.pk, over an encrypted HTTPS connection. The server runs on Jazz's own network and can be reached only from that network or its VPN. No other company or service receives your data from Data Guard.

The AI sites receive only the masked version of your prompts and files, exactly as they would receive anything you send them. What they do with it is governed by their own policies.

What is kept, and for how long

WhatWhereHow long
Link between placeholders and real values (needed to restore answers)Data Guard serverDeleted one hour after it was last used
Uploaded files and their masked copiesData Guard serverDeleted when the masking job finishes. Anything left over is removed within 6 hours.
Activity record: your work email, the time, and how many items of each type were masked or restoredData Guard server logsKept for security and troubleshooting. It never contains the real values, your prompts, your files or the answers.
Sign-in sessionData Guard server and a cookie in your browser8 hours, or until you sign out
Custom terms and chat-to-session linksYour browser's memory onlyUntil you close the browser
On/off choicesChrome storage (synced if you use Chrome sync)Until you change them or remove the extension

The placeholder links are never backed up, so they cannot outlive their expiry.
