Dr. Z for Chrome privacy policy

Effective date: 22 October 2026. Published by AristAI.

Dr. Z for Chrome is a browser extension for AristAI Mapper. It shows what needs you in Mapper, shows your Mapper chat in Chrome's side panel, sends pages you choose to Mapper, and opens or uses web pages for requests you make in Mapper after you allow each site. This policy explains what the extension handles and where it goes.

What the extension collects

DataWhenWhere it is kept or sent
Sign-in tokens for your Mapper account (a device token, a 90-day refresh token and 15-minute access tokens)When you link this browser from Mapper, Settings, DevicesKept in the extension's local storage in Chrome; sent only to your Mapper server
A device name such as "Chrome on macOS"When you link this browserSent to your Mapper server so you can see the browser in Settings, Devices
The text, title and address of a web pageOnly when you press Ask about this page, Add this page or Add to Mapper with Dr. Z, or when you allow Dr. Z to open a page for a request you madeSent only to your Mapper server
PDF files up to 7 MBOnly when you add a PDF page as course materials or evidenceSent only to your Mapper server
Screenshots of Dr. Z's own tabOnly while Dr. Z works in its own tab on sites you allowed for that requestSent only to your Mapper server
Your settings: Pause, whether Dr. Z shows on pages, the sites where you hid it and where you moved itWhen you change themKept in the extension's local storage in Chrome only

The extension does not collect your browsing history, your keystrokes or clicks, your passwords, payment details or your location. The small Dr. Z on your pages reads nothing on the page; it only notes the site name so it can stay hidden where you hid it, and that stays in Chrome. Dr. Z never types passwords or payment details.

Where it is sent

Only to your Mapper server, which is always at an aristai.io address (for example mapper-cn.aristai.io), over HTTPS. The Chat tab shows your Mapper page in the side panel, and that page is part of the same Mapper server. Mapper handles this data under your school's agreement with AristAI and the Mapper privacy terms.
